5.0 OPERATION

Once you have configured the Model 1203 properly (see Section

3.0) and plugged it into your equipment, you are ready to operate the unit. After the Model 1203 is properly installed, it should operate transparently—as if it were a standard cable connection. Operating power is derived from the RS-232 data and control signals; there is no “ON/OFF” switch.
