REMOTE INTERFACE
The Remote Interface connector is a dual RJ45. The upper socket is used for the Ethernet interface with the lower socket used
for RS232 or RS485. The pin-out for the matching RJ45 plug is shown in the following table and diagram:

( Note: The above pin-out allows a straight through RJ45 cable to be used for connection between the
terminal and the MA4003 chassis. It is also possible to use an RJ45 - DB25 adapter to connect to a PC or
similar RS232 standard serial port.

( Note: The above pin-out allows connection to an RS485 communications bus. If desired, an RS485 -
RS232 converter and an RJ45 - DB25 adapter can be used to connect to a PC or similar RS232 serial port.
