Push the cables through the sealing rubber. Use the holes with the correct diameter (see figure below). SEALING RUBBER BREAKTHROUGH Reserved for RS232-Interface cable GMKN1016 (not applicable for MOTOTRBO) Reserved for speaker cable Planned for RLN4856, RLN4858 Planned for RLN4836, RLN4857 DEMOUNTING OF THE CONTACTS It might be necessary to change the pin position in the connector housing. The following section describes how to remove the contacts from the connector housing. REMOVE CONTACTS FROM ACCESSORY CONNECTOR To remove the contacts from the connector push the tool into the front side slot as shown in the diagram and pull out the contact. 3 REMOVE CONTACTS FROM RS232 CONNECTOR (Not applicable for MOTOTRBO) Push with the tool into the slot and pull out the contact. ASSEMBLING RS232 INTERFACE CABLE, ACCESSORY CONNECTOR KIT AND SPEAKER CABLE The following pictures show the RS232 Interface Cable GMKN1016 (GMKN1016 is not applicable for MOTOTRBO) assembled with the speaker and the Accessory Connector Kit GMBN1021 with accessory connector. The front of both connector housings should be flush with each other. All cables should be fixed with a strap (see figure below). For more possibilities of the accessory connection, see the accessory connection plan. 4 PIN ASSIGNMENT OF THE ACCESSORY CONNECTOR Pin Function Description 1 Speaker - Speaker - and Speaker + (Pin 16) are used to connect an external speaker. The audio PA is a bridge amplifier with a minimum load resistance of 3.2 ohms. 2 EXT_MIC_AUDIO External Microphone. This microphone signal is independent of the microphone signal on the microphone connector. The DC impedance is 660 ohms and the AC impedance is 560 ohms. 3 EXTERNAL_PTT This is a digital input to trigger external PTT; active low; non active high 4 EXTERNAL_ALARM This is a digital output for External Alarm / Fault Indication; active low; open collector with 4k7 Ohms pull up to B+ 5 TX_AUDIO This input is intended for injecting signals into the transmit path. Input impedance > 10 k Ohms; input level = 775mVRMS 6 KEYFAIL This line supports the encryption module and the flash mode. Service Aids: 12 volts at this pin during power up/on brings the radio into the flash mode. 7 ANA_GROUND Analogue Ground 8 DIGITAL_GROUND Digital Ground 9 EMERGENCY To activate this functionality the pin has to be connected to ground. This will turn on the radio. The CPS details which functions may be assigned to this pin by the code plug. 10 IGNITION Connecting this pin to the ignition line of the vehicle that will automatically turn on the radio if ignition of the vehicle is turned on. High active. 11 RX_AUDIO This is the received RX signal. Output impedance approximate 600 Ohms; unsymmetrical; output level = 775mVRMS 12 AUDIO_PA_ENABLE This is a digital input. High level or pin open enables the audio PA; Low level disables the audio PA. 13 SWB + This voltage is available when the radio is switched on. The max. current is 1A. 14 HOOK This is a high active digital input. Low = on hook; High = off hook 15 SCI_DTR Data Terminal Ready, used for clock input for high speed flashing. Reserved for Service Aids. 16 SPEAKER + Positive output of radio's audio PA (see Pin 1). 17 SCI_CTS Clear To Send. Reserved for Service Aids. 18 SCI_RTS Request To Send. Reserved for Service Aids. 19 SCI_RXD Receive Data. Reserved for Service Aids. 20 SCI_TXD Transmit Data. Reserved for Service Aids. 5 PIN ASSIGNMENT OF THE MOTOTRBO RADIO ACCESSORY CONNECTOR Pin Function Description 1 Speaker - Speaker - and Speaker + (Pin 16) are used to connect an external speaker. The audio PA is a bridge amplifier with a minimum load resistance of 3.2 ohms. 2 EXT_MIC_AUDIO External Microphone. This microphone signal is independent of the microphone signal on the front microphone connector. The nominal input level is 80 mVRMS for 60% of the maximum deviation. The DC impedance is 660 ohms and the AC impedance is 560 ohms. 3 GPI_1 (EXT_PTT) 5 V Level GPI which can be set up to trigger on a PTT input. Active low; non-active high. 4 VIP_1 (EXT_ALARM) 12 V Supply which can be set up for a digital output for External Alarm/Fault indication; active low. 5 FLAT_TX_AUDIO Data input. This input is for injecting signals into the transmit path that should be filtered; for example, the analog output of a modem. The nominal input level is 150 mVRMS for 60% of the maximum deviation and the input impedance is greater than 25 K. 6 UART_CTS/GPIO_3 UART_CTS for MOTOTRBO Series 01 radios and it’s intended for Motorola Internal Use Only. 5 V Level GPIO for MOTOTRBO Series 02 radios. 7 Ground Radio Ground. 8 GPIO_4 5 V Level GPIO. 9 EMERGENCY_SW To activate this functionality the pin has to be connected to ground. This will turn on the radio. The CPS details which functions may be assigned to this pin by the code plug. 10 IGNITION_SENSE Connecting this pin to the ignition line of the vehicle that will automatically turn on the radio if ignition of the vehicle is turned on. The CPS details which functions may be assigned to this pin by the code plug; active high. 11 RX_AUDIO Fixed level (independent of volume level) received audio signal, including alert tones. Flat or de-emphasis are programmed by CPS. Output voltage is approximately 330 mVRMS per 1 kHz of deviation. 12 GPIO_7 5 V Level GPIO. 13 SWB + This voltage is available when the radio is switched on. The max. current is 1.5 A. 6 Pin Function Description 14 GPIO_8 5 V Level GPIO. 15 RSSI Receive Signal Strength Indicator. A receive signal strength of –120 dBm gives about 1.12 Vdc at pin 15. A receive signal strength of –60 dBm gives about 2.44 Vdc at pin 15. The receive signal strength for levels in between can be linearly calculated. For signals strengths greater than –60 dBm, the voltage stays relatively flat at ~ 2.44 Vdc. 16 Speaker + Positive output of radio's audio PA (see Pin 1). 17 UART_TX / USB D+ UART_TX for MOTOTRBO Series 01 radios and it is intended for Motorola Internal Use Only. USB Data + for MOTOTRBO Series 02 radios. Caution: Applying greater than 5 V to the pin can cause damage to the circuit. 18 UART_RX / USB D- UART_RX for MOTOTRBO Series 01 radios and it is intended for Motorola Internal Use Only. USB Data - for MOTOTRBO Series 02 radios. Caution: Applying greater than 5 V to the pin can cause damage to the circuit. 19 UART_RTS / VBUS UART_RTS for MOTOTRBO Series 01 radios and it is intended for Motorola Internal Use Only. 5 V VBUS for MOTOTRBO Series 02 radios. Caution: Applying greater than 5 V to the pin can cause damage to the circuit. 20 Ground / USB Ground Radio ground for MOTOTRBO Series 01 radios. USB ground for MOTOTRBO Series 02 radios. 7 NOTES 8 m MOTOROLA, MOTO, MOTOROLA SOLUTIONS and the Stylized M logo are trademarks or registered trademarks of Motorola Trademark Holdings, LLC and are used under license.
