Host Serial Port 
 
The RS-232 Host Serial Port provides serial communications between the Reader/Encoder and 
the Host Computer.  In addition, the Host Serial Port carries DC power from the remote power 
pack to the Reader/Encoder.  The Host Serial Port is capable of communication speeds of up to 
115 K bits/sec. 
 
USB Port  
 
The Host USB 1.1 Port provides communications between the Reader/Encoder and the Host 
Computer.  The USB Cable, 5-pin mini B Plug, connects to host 4-pin USB Type A Plug, with 
10-pin RJ45 and 12V/Ground connector for Power Supply.    
 
Auxiliary Serial Port 
 
The Auxiliary Serial Port provides serial communications and power between the 
Reader/Encoder and an external device.  The Auxiliary Serial Port is capable of communication 
speeds of up to 19.2 Kbits/sec.  The port is also capable of carrying +12 VDC at up to 1 A for a 
device connected to this port.   

 

Power Input 
 
The Reader/Encoder is powered by a 12 VDC power-pack.  The +12 VDC power is carried to 
the Reader/Encoder as part of the Host Serial cable. 
 
All other voltages required by the Main PCB are generated onboard as required. 
 
The input connector and cabling carry power to support the Reader/Encoder. 
 
Polarization and Securement of Serial Port Cables 
 
The ports, located at the rear of the Reader/Encoder, use RJ connectors with locking tabs, which 
assist in securing the cable to the Reader/Encoder.
