This section contains information on the cable and pin assignments for the
ProLinx gateway's serial ports (RS-232/422/485). The ProLinx gateway will come
with one to five serial ports, depending on the configuration purchased. In all
cases, the protocol serial ports will have the same pinouts.
Example: The 5202-MNET-MCM4 gateway contains five serial communication ports; four
configurable protocol application ports and one Configuration/ Debug port.
The 5201-MNET-MCM gateway contains two serial communication ports; one configurable
protocol application port and one Configuration/Debug port.
Each physical serial port has an eight-pin Mini-DIN jack connector. A six-inch
Mini-DIN-8Male to DB-9Male adapter cable is provided for each serial port. The
DB-9M provides connections for RS-232, wired as Data Terminal Equipment
(DTE), RS-422 and RS-485. The diagrams in the following topics detail the pin
assignments for several possible electrical interface connections.
