VMSE Interfaces
Serial Interface
The VMSE has RJ45 and screw block serial ports. The RJ45 port only supports
RS232, whereas the screw block port supports RS232 and RS485/422. By setting the
switch located on the face of the VMSE and configuring the VMSE setup, RS232 or
RS485/422 can be selected.
NOTE: The VMSE is a single serial port device, meaning that only one port can be
used at a time. In the configuration menu, Channel One refers to either one of the
ports being used.
