Setting Up the System - 140
Power Supply
A plug in power transformer is supplied by Onity.
Simply plug this transformer into the wall outlet or
power strip, and connect to the jack labeled 12VDC, as
shown in Figure 11 on page 142 below.

Connecting Additional Encoders
When configured as a main station, the HT22 can be a
file server for up to seven HT22 auxiliary encoders.
These encoders are connected in “daisy chain”
configuration. Beginning with the main station, each
encoder is connected in a continuous string. The first
and last encoder in this string must have the terminating
resistor set to the ON position, as shown in Figure 12
on page 143. All of the other encoders in the string
must have the terminating resistor set to the OFF
position. The total length of the string may not exceed
4500 feet.
