Serial Line Interfaces

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).
