Serial Line Interfaces
The VMSE has RJ45 and screw block serial ports. The RJ45 port only supports RS--
232, whereas the screw block port supports RS-232 and RS-485/422. By setting the
switch located on the face of the VMSE and by selecting the matching setting with
the configuration software, RS-232 or RS-485/422 can be selected.
NOTE: The VMSE is a one 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. If Channel two appears, it should be disregarded (this channel
applies to another type of product).
