2.2.1 RS232 Serial Cable
The following drawing shows the connection diagram for the DB-9 Male and DB-9 Female cables to the
solder pads on the circuit board at J1.
Pin 9 on the DB-9 connector is shown with +7-24 VDC going to Pin 2 of J1. This an optional method of
supplying power to the device. It is not required if you use a different power source. The factory default
configuration has no internal connection to J1-pin 2. For more details about power, see Power Options on
page 2-10.
The signal on J1-pin 9 is named XCFG PB, which is the External Configuration Push Button input. This
signal is NOT connected to the DB9-Male cable at the factory. If you need the push button input, contact the
sales department to get a quote for a custom cable.
