Connecting the Reader to Another Device<br />

You can physically connect the reader to another device using one of the three<br />

methods described next.<br />

Note: If you have a JR<strong>2020</strong>, you do not physically connect the reader to another device.<br />

The reader communicates through radio signals instead of a physical connection.<br />

Communications Dock Place the reader in a communications dock and connect<br />

one or two devices to the dock’s serial ports. The dock’s network port is a<br />

25-pin DTE connector and the auxiliary port is a 25-pin DCE connector.<br />

Depending on how you set the dock’s DIP switches, the reader communicates<br />

with both ports or the ports communicate with each other.<br />

If you plan to run Interlnk with the reader connected to a host computer<br />

through the communications dock, you must connect the dock to the host<br />

computer with a 3-wire (2, 3, and 7) cable for Interlnk to operate properly.<br />

If the reader will communicate through only one port (network or auxiliary) on<br />

the reader communications dock, you must select that port with the<br />

Communications Dock Port command. For help, see “Communications Dock<br />

Port” in Chapter 12 or the <strong>JANUS</strong> <strong>2020</strong> Communications Dock Quick Reference<br />

Guide.<br />
