INSTALLATION MTM700/MTM800 Mobile Terminal / Installation Manual 65

25-Pin subD Connector

Connection of Data Devices:

This connector offers a connectivity between a Data Device with RS232 interface and the Expansion

Head Radio with its SB9600 interface. This interface is a special Motorola Serial Interface. For fur-

ther information of the SB9600 Interface Cable please refer to section „Connecting Cables“.

Connection of the Motorcycle Control Head:

If this connection to a Data Device is not required it is also possible to connect the Motorcycle Con-

trol Head (Motorola P/N: SDLN4506)

NOTE: The radio must be turned ON/OFF via the Ignition Sense Cable HKN9327 which has to be

connected on Pin 10 of the Accessory Connector on the rear side of the radio.

Pin Function Description

1 GND Ground

2 RS232_SCI_TX Transmit Data (4-wire RS232 with RS232 level)

3 RS232_SCI_RX Receive Data (4-wire RS232 with RS232 level)

4 RS232_RTS Request to Send (4-wire RS232 with RS232 level)

5 RS232_CTS Clear to Send (4-wire RS232 with RS232 level)

6 FLT_A+ This voltage is at battery voltage level and is available as long as the radio is connected

to the supply voltage. A fuse in the radio prevents further circuit damage in case of

shorting this pin to ground. This pin is only used together with the pins 14, 20, and 23 to

select flashing and programming mode, SB9600 mode or to switch the radio on.

7 Ground Ground for RS232

8 SB9600_BUSY SB9600 Busy

9 NC Not Connected

10 NC Not Connected

11 NC Not Connected

12 SW_B+ Switched U

+ / 100 mA

13 SB9600_BUS- SB9600 BUS-

14 FLASH_MODE This input is intended to switch the radio into flashing & programming mode. When the

radio is switched off and this pin is connected with pin 6 (FLT A+), the radio switches on

and enters flashing & programming mode.

15 SB9600_BUS+ SB9600 BUS+.

16 Internal Mic Audio This input depends on radio programming mode. This microphone signal is independent

of the microphone signal on the accessory connector. The nominal input level is 80 mV.

The DC impedance is 660 ohms and the AC impedance is 560 ohms.

17 SB9600-Reset This output can be used to reset a SB9600 device.

18 NC Not Connected

19 GROUND Ground

20 Radio

ON/OFF

The radio can be switched on by connecting this pin with pin 6 (FLT A+). As long as both

pins are connected, the radio will be switched on.
