SAE J1708 Data Interface Cable
Model 1708CAB9
Make the connection to J1708 data bus systems using the
popular 9-pin Deutsch connector with the 1708CAB9 interface cable.
This 1.8 meter (6 feet) long, 18 AWG shielded cable is terminated
with a 9-contact circular socket. The Data A, Data B, and ground
conductors are stripped and tinned at the opposite end for easy
connection to Model 232SAER or J1708P1 which converts J1708
data to the RS-232 Standard. The remaining four connections are
included in the cable, but cut flush with the insulation.
Vehicles may provide a voltage on Pin B (orange wire) of the connector. Note that, if this wire is connected to the
+12V power input on the Model 232SAER or J1708P1, the voltage must not exceed 16 volts otherwise the 232SAER or
J1708P1 will be damaged.
