Accessories
The Accessories set in a radio or repeater configuration/codeplug contains settings relating to the accessory connector.
General
Hook Type
Hook Type allows the user to take the radio auto-reset squelch mode and overrides the auto-reset timer. When set to Disabled, the Hook feature is completely inactive. When set to Timed, the Auto Reset Timer will be started when the microphone goes off hook. When set to Permanent, the Auto Reset Timer is disabled while the microphone is off hook.
This feature is supported on mobiles in analogue mode only.
The hang-up stud on all mobile microphones consists of an electrically isolated stud and ring. When the microphone is placed onto the hang-up clip (i.e. the microphone goes on hook), the hook line in the radio is triggered and auto-reset will not be overridden or started.
Bluetooth
Analogue Microphone Gain (written as Analog Mic Gain in the CPS/RM) and Digital Microphone Gain set the gain of the attached Bluetooth accessory. The valid range for both is -20dB to +20dB in 1dB steps. The default values are -10 and -6dB. Adjusting these values has no impact on the wired microphone gain.
This is only supported in Bluetooth capable radios.

GPIO Physical Pins
The Feature setting defines what input or output will be on the GPIO (General Purpose Input Output) pin of the Accessory Connector.[1][2][3]
| Feature | Available on GPIO | Description |
|---|---|---|
| 5 Tone Call 1 – 6 | GPIO2, GPIO3, GPIO4, GPIO6, GPIO7, and GPIO8 | These are output lines, that when activated, sends the telegram as configured for Call buttons (Call 1, Call 2, Call 3, Call 4, Call 5 and Call 6). The same telegram is sent when Call 1 button is pressed (available when the 5 Tone feature is enabled in the device). |
| 5 Tone Decoder Output Control | GPIO2, GPIO3, GPIO4, GPIO6, GPIO7, and GPIO8 | This is an output line that is asserted or deasserted based on the Decoder Output Control options programmed in the radio upon successful decoding of a telegram sequence (available when the 5 Tone feature is enabled in the device). |
| AC Power Failure | All GPIO | Allows the user to enable/disable the AC Power Failure. When enabled, the repeater shows the alarm related to the AC failure. |
| Antenna Relay | All GPIO | When the radio is operating as a base station (instead of as a repeater), an antenna relay may be used to share the antenna between the receiver and transmitter connectors.
When the radio is in the receive mode, the Antenna Relay pin is set to an "INACTIVE" signal condition and the antenna relay is deactivated. When transitioning to the transmit state, the Antenna Relay pin is set to an "ACTIVE" signal condition. The antenna relay is activated and after a short delay the repeater/base station will begin transmitting. |
| Carrier Operated Relay | All GPIO | This is an output line to the Analog Phone Patch box that is activated whenever the repeater starts transmission to the Analog Phone Patch box and deactivated whenever the repeater ends transmission to the Analog Phone Patch box (applicable to repeater configuration only). |
| Channel Select 1 – 6 | All GPIO | This is an input line that allows an external device to select a channel. When the pin is assigned to this option, the pin can be triggered individually or combined with other pins assigned to this option to select a channel (applicable to Mobile configuration only). |
| Clear To Send | GPIO2, GPIO3, GPIO4, GPIO6, GPIO7, and GPIO8 | This is an output line used for indicating to an external modem that the radio has keyed up and data transmission may begin. This feature is useful because the line will not be asserted until audible transmission can really take place. MDC side-tones and Transmit Inhibit on Busy can result in delayed or blocked channel access. |
| CSQ Detect | All GPIO | This is an output line that indicates to the user when an RX signal is present (applicable to Analog mode only). |
| Data PTT | GPIO1, GPIO2, GPIO3, GPIO4, GPIO6, GPIO7, and GPIO8 | This is an input line used for data transmission from a device connected to a radio, another radio, or device. When the device that is connected to the radio is set to send data over the air, for instance, MDC data or GNSS coordinates, it triggers the Data PTT before it sends the data to the radio which in turn transmits the data over the air to the target radio or another device (applicable to Analog mode, Mobile configuration only). Overrides Voice |
| Data Revert | GPIO1, GPIO2, GPIO3, GPIO4, GPIO6, GPIO7, and GPIO8 | This is an input line used for predefining an alternative channel to be used during data transmission (applicable to Analog mode, Mobile configuration only). |
| Disable | All GPIO | This is an input line, that when activated, disables the repeater. When this is de-activated, the repeater is re-enabled. Note that the repeater will reset before changing its state. |
| Ext Alarm/Horn & Lights | GPIO2 and GPIO10 | This is an output line used to inform the user using the horn or/and lights if there is an incoming call alert/private call when the user is not in their vehicle (applicable to Mobile configuration only). See also Alarm (Horn & Lights). |
| Ext Mic Off Hook | GPIO1, GPIO2, GPIO3, GPIO4, GPIO6, GPIO7, and GPIO8 | This is an input line used for voice transmission via an external microphone with Push-to-Talk (PTT) buttons (applicable to Mobile configuration only).
This is an input line, that when activated, will key the repeater and cause the repeater to transmit audio any present on the Ext Mic input line. PTT priority is determined by the Audio Priority setting in CPS 2.0 (applicable to Analog mode, Repeater configuration only). |
| Ext Mic PTT | GPIO1, GPIO2, GPIO3, GPIO4, GPIO6, GPIO7, and GPIO8 | This is an input line used for voice transmission through an external microphone with Push-to-Talk (PTT) buttons. |
| External PTT | All GPIO | This is an input line, that when activated, keys the repeater and causes the repeater to transmit audio presence on the TX pins of the J7 backplane connector. PTT priority is determined by the Audio Priority setting in CPS 2.0 (applicable to Analog mode). |
| FCC Type 2 Monitor | All GPIO | This is an input line, that when activated, prevents the repeater from keying up and from repeating inbound calls in a IP Site Connect environment (applicable to Repeater configuration only). |
| Football Knockdown | All GPIO | This is an input line, that when activated, disables the receive and transmit operations of the repeater for as long as the pin is activated. CWID will not be transmitted while this option line is active (applicable to Single Site Digital mode, Repeater configuration only). |
| Generic Input 1 – 6 | GPIO1, GPIO2, GPIO3, GPIO4, GPIO6, GPIO7, and GPIO8 | These input lines allow for status indication to the option board and level switching from the option board (applicable to Mobile configuration only). |
| Generic Output 1– 3 | GPIO1. GPIO2, GPIO3, GPIO4, GPIO6, GPIO7, GPIO8, and GPIO10. | These output lines allow for status indication to the option board and level switching from the option board (applicable to Mobile configuration only). |
| Generic Outputs 2 – 6 | GPIO1, GPIO2, GPIO3, GPIO4 (until output 5 only), GPIO6, GPIO7, GPIO8, and GPIO10. | These output lines allow for status indication to the option board and level switching from the option board (applicable to Mobile configuration only). |
| Major Alarm | ALL GPIO | This is an output line that is activated by a repeater when it enters a locked state after three instances of major hardware failure have occurred. |
| Minor Alarm | ALL GPIO | This is an output line, that is activated by a repeater when it is reporting an alarm triggered by minor hardware failure. |
| Monitor | ALL GPIO | This is an input line that allows the user to monitor a channel.
In analog mode, the user is able to listen to the traffic, in other words, the radio will unmute to the actual voice or data traffic in process. In digital mode, the user can only check if activity is present before transmitting, in other words, the radio will emit an audible/visual alert if there is activity present, but it will not unmute to the actual voice or data traffic in process. For a channel to be monitored, TX Admit Criteria of the channel should be set to Always. A channel cannot be monitored if any other value of TX Admit Criteria is selected. |
| Multi-Button PTT | GPIO1, GPIO2, GPIO3, and GPIO4. | When a cable is attached, the MB_PTT (active) causes the radio to change to a specified channel and assert the PTT. In other words, one button press on the accessory triggers a Channel Change and PTT. This choice is hidden when the Multi-Button PTT feature is disabled. |
| PL/Talkgroup Detect | ALL GPIO | For radio configuration, this is an output line used for permitting an output to be activated when the radio is receiving carrier and the Unmute Rule for the radio is satisfied on the channel. For repeater configuration, this is an output line that is activated when RX signal contains Private Line (PL) code (applicable to Analog mode only). |
| Repeater Knockdown | ALL GPIO | This is an input line, that when activated, will disable the internal repeat path of the repeater for as long as the pin is activated. An external device can then control when the repeater keys-up (applicable to Analog mode, Repeater configuration only). |
| Request to Send | GPIO1, GPIO2, GPIO3, GPIO4, GPIO6, GPIO7, and GPIO8. | This is an input line for initiating a data call from an external device and in doing so, the radio transmits without sending sub-audible signaling, in other words. the following are disabled: PL encode, Reverse Burst/TOC, and PTT ID (applicable to Analog mode). |
| Reset | ALL GPIO | This is an input line, that when activated, resets the repeater. |
| Response Inhibit | GPIO8 | This is an input line where it allows user to place the radio in a state (through a button press) whereby the radio will not generate any outgoing transmissions in response to unsolicited incoming transmissions. This includes not transmitting back to Radio Check", Radio Monitor , Radio Disable, Confirmed Private Calls, Confirmed Text Message, and so forth. In this state, the user is still be able to initiate outgoing transmissions manually (for example, voice transmissions and text messages). |
| RX Audio Mute | GPIO1, GPIO2, GPIO3, GPIO4, GPIO6, GPIO7, and GPIO8. | This is an input line, that when activated, mutes the audio for the receiving radio even though the radio meets all the unmuting conditions (applicable to Analog mode). |
| Site Slot Sync Output | ALL GPIO | This is an output line, that when activated, relays master timing signals to slot sync slave repeaters in a MOTOTRBO Link system. This function is used with the GPIO Slot Timing Master field. |
| Site Slot Sync Input | ALL GPIO | This is an input line, that when activated, receives master timing signals from the slot sync master repeater in a MOTOTRBO Link system. This function is used with the GPIO Slot Timing Master field. |
| Telemetry VIO 1 – 3 | GPIO1 | These lines can be an input or an output line depending on the configuration in the radio. Setting the input or output capability on this line allows the user to control and monitor its own pin or another radio pin, which in turn can control and monitor any external hardware that is attached to the radio. |
| Telemetry VIO 1 – 5 | GPIO1, GPIO2, GPIO3, GPIO4, GPIO6, GPIO7, and GPIO8. | These lines can be an input or an output line depending on the configuration in the radio. Setting the input or output capability on this line allows the user to control and monitor its own pin or another radio pin, which in turn can control and monitor any external hardware that is attached to the radio. |
| TOC/Reverse Burst Disable | GPIO1, GPIO2, GPIO3, GPIO4, GPIO6, GPIO7, and GPIO8. | This is an input line used to inhibit the transmission of the TPL Reverse Burst or the DPL Turn-Off Code (applicable to Analog mode, Mobile configuration only). |
| Transmit Inhibit | GPIO2, GPIO3, GPIO6, GPIO7, and GPIO8. | This is an input line used to prevent the station from being keyed through any PTT (external or internal). The station remains functional in every other regard. |
| TX PL Inhibit | ALL GPIO | This is an input line, that when activated, will inhibit the transmission of sub-audible signaling (applicable to Analog mode, Mobile and Repeater configuration only). |
| TX Power Level High | ALL GPIO | This is an input line, that when activated, sets the repeater to use the high power level for TX transmission. When de-activated, the repeater uses the low power level for TX transmission.
NOTE: The repeater resets before changing its TX power level (applicable to Repeater configuration only). |
| Unassigned | ALL GPIO | No functionality is assigned to the pin. |

Active Level
Active Level defines what state is needed in order to trigger a GPIO configured as an input. It also defines what state the pin will be in when a GPIO output is active (the condition is true). For example, if GPIO2 is set to CSQ Detect and Active Level is set to High, then this GPIO will go high whenever carrier is present on the current channel. If GPIO3 is set to External PTT and the Active Level is Low, then in order to make the radio transmit, the pin needs to be be shorted/switched to ground (0V relative the the minus power line).
There is an internal pull-up resistor that pulls a GPIO input high if no external equipment is connected to that pin. Setting the Active Level of the input to High causes the feature assigned to that pin to be triggered when the radio powers up. To avoid this condition on input GPIOs, are not connected to any external equipment, set the Active Level to Low instead.
GPIO configured as an output will have a open collector with an internal pull-up resistor.
The GPIO pin follows TTL levels, in that:
| Logic Level | Valid Range |
|---|---|
| Low | 0 - 2V |
| High | 3 - 5V |
Debounce
Ticking this adds a debounce period to GPIO inputs. The duration of the debounce is set by Debounce Duration (in the General section above).
GNSS Report
If ticked, a GNSS update will be sent whenever the GPIO input is triggered.
