Remarks
1 EMP2-X4S2 RS422/RS485 RS422/RS485 Total of four COM ports are detected in the Device
Manager. However, only two COM ports can be
accessed. Assume that the first COM port of EMP2-
X4S2 is COM X, as seen in the device manager, then,
based on the cable tag:
RS-422 A - COM X
RS-422 B - COM X+1
RS-485 A - COM X+2
RS-485 B - COM X+3
2 EMP2-X2S1 RS232 RS232 Total of two COM ports are detected in the Device
Manager. Assume that the first COM port of EMP2-X2S1
is COM X, then, based on the cable tag:
Isolated COM A - COM X
Isolated COM B - COM X+1
For EMP2-X2S1:
Both EMP2-X2S1 and EMP2-X4S2 use the same VID and DID. By default, the EMP2-X2S1 module uses the driver files of
the EMP2-X4S2 module, and so the device manager shows four COM ports. To overcome this issue, manually install the
EMP2-X2S1 Windows 10 64-bit driver package.
