3.7.5 RS232C Serial Interface Connector
An RS232 serial interface connector is located on the rear panel on all models. Note that two
versions of the RS232 exist on the MX model series depending on the age of the unit. Older
models can be identified by the fact that they will not have a USB interface.

Table 3-10: RS232C Connector pin out – MX with RS232 but no USB
On MX models without a USB interface, a special RS232 cable is required to connect to a PC.
With these MX models, a special 13 foot / 4 meter long cable is supplied in the MX 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.
MX models that have both RS232 and USB interface use a more common straight through DB9
male to DB9 female serial cable, which is supplied in the MX ship kit for these models.
