One driver at each display installation is designated as the host driver, which receives its signal directly
from the DataMaster controller on its Signal IN terminals. It is the only driver that is connected to the photo/
temperature sensor. The Signal OUT terminals on the host connect to the client driver.
Select the host driver by inserting the Protocol-4 plug into the five-pin protocol jack (J20). Refer to Figure 9 or
Drawing A-166216 for location of the protocol jack.
With a time and temperature display there is usually only one host and one client. The client driver receives
signal from the host driver, and the client can re-drive this signal to other drivers.
