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.
