Configuring the IR network topology

It is necessary to tell the readers cooperating on the IR network about each other via the

configuration settings.

Each reader can communicate to one reader on its “Left” and one reader on its “Right”. Each can be

separately enabled. The reader on which the network settings are being enterred is the “Center”

from its own persective but will be Left or Right reader to the adjacent readers.

Left Reader: The Left Reader is the reader whose highest Port number antenna is adjacent to the

antenna with the lowest Port number on the Center Reader.

Right Reader: The Right Reader is the reader whose lowest Port number antenna is adjacent to the

antenna with the highest Port number on the Center Reader.

Note: While the MPR 4.1 supports separating the antenna position from the Port order, in order

to use IR the antenna order must be matched to Port order and run from left to right (or

right to left) in the IR cooperating readers.

Note: A single (voting) Group ID must be used in each reader

Note: The transponder timeout values for the (voting) Group IDs must be the same across all

readers.

Note: The transponder timeout, set in the Group tab on the Configure panel, must be greater

than the time difference between all Reader clocks in the network.

Note: The protocol and tag programming settings must be the same on each reader for the

protocols involved in the IR network

Note: A reader restart is usually required when the IR network configuration is completed on all

readers

The following example shows how to configure the IR network based on where the Reader sits in the

site.

Example: Reader 1 in Figure 5-14 has a Reader on its right (Reader 2) but no Reader on the left.

Reader 2 in Figure 5-14 has a Reader on its right (Reader 3) and a Reader on its left (Reader 1). Reader

3 in Figure 5-14 has a Reader on its right (Reader 4) and a Reader on its left (Reader 2).
