2.3 Device ID
A rotary control on the rear of the module (as shown) controls
device ID setting and can be set from 0 to 7. The device ID allows
dedicated control of the USB-2405 module irrespective of the con-
nected USB port. When more than one USB module of the same
type is connected, each must be set to a different ID to avoid con-
flicts and errors in operation.
