Setting Switch
There are two setting switches. “x16” and “x1” represent high bits and low bits of Module
ID respectively.
Factory settings “00” can be used when only one device per model is connected to one
computer. Each device should be assigned a unique Module ID in the range of 00 - 7Fh
when several devices with the same model are being connected.
