5.0 OPERATION
Once you have configured the Model 1200 properly (see section 4.0,
“Configuration” on page 7) and plugged it into your equipment, you are
ready to operate the unit. After the Model 1200 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.

put signal on the RS-232.
