MX20 and MX40 Processor Serial Port
A standard serial cable is used to connect the MX20 and MX40 Processors to the serial port on an external device (e.g. ter-
minal, PLC, motion controller, data recorder). This may require using a null modem cable or adapter. The serial port does
not support hardware (CTS/RTS) or software (Xon/Xoff) data flow control. The M-Series Processor supports RS-232
communication protocol only. RS-485 is not supported.
MX80 Processor Serial Ports
The MX80 processor provides four serial port connections. The connector on the front panel is Serial Port 1 (COM 5).
CAM 1 controls this serial port. Use a standard serial cable to connect this serial port to an external device (e.g. terminal,
PLC, motion controller, data recorder).
The connector on the rear panel provides three serial port connections for Serial Ports 2, 3, and 4 (COM 2, 3, and 4 respec-
tively). CAM 2 controls Serial Port 2, CAM 3 controls Serial Port 3, and CAM 4 controls Serial Port 4. Use the provided
cable to connect the rear connector to serial ports on an external device. This cable has a DB-62P connector on one end
and three standard serial port connectors (DB9) on the other end. The connector wiring pin numbers on these three con-
nectors are the same as the MX20 and MX40 (see “MX20 and MX40 Processor Serial Port” on page 5-2).
Connecting any of these serial ports may require using a null modem cable or adapter. The serial ports do not support
hardware (CTS/RTS) or software (Xon/Xoff) data flow control. They support RS-232 communication protocol only. RS-
485 is not supported.
MX40 VGA Connector
The MX40 processor requires a monitor and keyboard when it first starts, and to configure the system. The VGA cable
can be a maximum of 10 meters long.
