Configuring the Communications Protocols<br />

Next, identify and configure one or more communications protocols to use on<br />

the selected COM port.<br />

To configure a communications protocol or protocols for a COM port<br />

1. Select the communications protocol with the Communications Protocol,<br />

Configure command. The reader applies all subsequent changes in its<br />

communications configuration to the selected protocol. For help, see<br />

“Communications Protocol, Configure” in Chapter 12.<br />

Note: For a CrossBar network, configure the reader for Multi-Drop protocol.<br />

2. Set the parameters (such as baud rate) for the communications protocol.<br />

Make sure the values you set for the reader match the values set for the<br />

device it will communicate with.<br />

There are three ways to set communications parameters:<br />

• You can use IC.EXE.<br />

• You can scan the configuration commands listed in Chapter 12.<br />

• You can use DOS commands. For example, you can type the MODE<br />

command at the DOS prompt, or an application using the COM port<br />

can execute standard DOS commands.<br />

The method you choose depends on the COM port, as follows:<br />

Methods for Setting Communications Parameters<br />

COM Port Use IC.EXE? Scan Commands? Type DOS Commands?<br />

COM1 Yes Yes Yes<br />

RF (logical COM4) Yes Yes No<br />

COM4 No Yes Yes<br />

3. Repeat Steps 1 and 2 for every communications protocol you want to<br />

configure for the selected COM port.<br />

Here are the parameters you can set for each communications protocol:<br />

Multi-Drop Protocol Parameters<br />

• Baud rate, parity, and data bits<br />

• Transmit abort timeout<br />

• Address, multi-drop
