Advanced Repeater Installation

Installing more than one repeater, or getting a repeater to receive signals from multiple

stations/repeaters, follows the same basic processes used to install a single repeater into a

single station/single receiver network.

See the individual installation instructions for the advanced repeater configuration you’ve

selected.

Multiple Repeater (Daisy-Chain) Installation

A daisy-chain installation is very similar to a single repeater installation with the excep-

tion that more than one repeater is involved. See “Single Repeater Installation” on

page 13 for detailed instructions on configuring the transmitter and console for wireless

repeater use. This section covers the additional steps necessary to get a chain of repeaters

set up and communicating.

Verifying/Changing Repeater IDs

A repeater automatically retransmits all the data packets sent by the previous repeater in

the chain, except repeater A, which as the first in the chain retransmits only data packets

from the stations selected on its Transmitter DIP switch.

Note: Each repeater will only look for and acquire repeater signals from the previous repeater in the chain.

To set the repeater IDs for all of the repeaters in the chain:

1. Identify the repeater that will be positioned closest to the sensor station.

2. Verify that the repeater DIP switch in this repeater unit is set to the default ID of A (all

DIP switches in the OFF position).

3. Identify the next repeater in the chain.

4. Change the Repeater ID to B using the table below:

5. Continue setting the next sequential repeater ID for each repeater in the chain.
