Chapter 4  Installing the Encompass 4 Reader

TransCore Proprietary

4-55

Connecting Communications

TransCore offers reader models that communicate through RS–232, RS–422, and Wiegand 

interface protocols. This section describes the procedures and materials required for connecting the 

communications to the junction box and to the sense input and sense output circuits.

Required Materials

You need the following materials to connect the communications cable to the PC:

• 

PC or laptop

• 

Any terminal emulation program running on a PC

• 

Communications cable to connect to the COM1 port on your PC

Connecting the Encompass 4 Reader to the PC

Encompass 4 Reader communications and customer interface signals are supplied from the Encompass 

4 Reader to the host through a multi-wire cable, which is a 13-pair pigtail. The connector for this cable is 

located on the back of the Encompass 4 Reader. Refer to the following sections to connect the appropriate 

communications wires from the cable to the terminal strip that is located inside the junction box.
These sections contain instructions for connecting RS–232, RS–422, and Wiegand communications 

between the Encompass 4 Reader and the PC. Each section contains wiring instructions and pin 

assignments followed by step-by-step connection procedures.
The Encompass 4 Reader can remain powered up while connecting reader-to-host PC communications.

RS–232 Interface

RS–232 interface signals are supplied by three or five wires from the Encompass 4 Reader 

communications cable. The pin assignments for the signal to the host male DB9 and DB25 connectors are 

shown in boldface in 

“Pin Assignments for Signal to Host Connectors” on page 4-38
