RS-232 Serial Connection
Turn off power to the terminal/PC and connect the reader to the terminal/PC serial port via the 
RS-232 cable, as shown in Figure 1. If the terminal will not support POT (Power Off the 
Terminal) to supply reader power, use the approved power supply 
(AC Adapter). Plug the AC 
Adapter barrel connector into the socket on the RS-232 cable connector and the AC Adapter 
plug into a standard power outlet.
