Setting a Module ID
The host computer distinguishes and keeps track of the modules of same model by assigning Module IDs
to them. Factory settings “00” can be used when only one module per model is connected to one
computer.
Each module should be assigned a unique Module ID in the range of 00 - 7Fh when several modules with
the same model are being connected.
There are two rotary switches, moreover, “x16” and “x1” represent high bits and low bits of Module ID
respectively.
Use a flathead screwdriver or similar to open the cover on the underside of the GP-IB(USB)FL. This
exposes the rotary SW to set the Module ID. As shown in Figure 2.2, an easy way to open the cover is to
insert the tip of the screwdriver into the slot on the underside of the connection cable and then rotate the
screwdriver.
