Table 3-5: RS232C Connector – Units with RS232 but no USB.
On i/iX models without a USB interface, a special RS232 cable is required to connect to a PC.
With these models, a special 6 foot / 2 meter long cable (CI P/N 7000-263-1) is supplied in the
i/iX Series ship-kit. The wiring diagram for this cable is shown below in case a longer cable has
to be constructed. Alternatively, a generic straight thru DB9 male to DB9 female cable can be
used to extend the supplied cable.
The i/iX models that have both RS232 and USB interface use a regular straight through DB9
male to DB9 female serial cable, which is supplied in the i/iX ship kit for these models. To
connect the 5001iX to a PC’s 9-pin DB9 serial port, a special RS232 cable is required.
