How do I know which driver is the “host” (that is, which driver connects to the
DataMaster

™

100 controller)?

All driver boards are identical until you install the Protocol 4 plug. The driver
containing the Protocol 4 plug becomes the host. (Refer to the section titled Power
and Signal Connection of the manual.)

Which driver do I connect the temperature and light sensor to?

Connect the sensor to the host driver only (the driver that is connected to the
DataMaster 100 controller).

I have a price display with multiple lines. Which line do I put the host driver
on?

You can designate any driver as the host driver by installing the protocol plug in jack
J20. Be sure to set the line number of each driver by installing the correct address
plug. Use the Signal Out terminals of this display to go to the driver on the next line.
Connect signal to all other displays using the Signal Out terminals of the previous
line. (Refer to the section titled Power and Signal Connection of the manual.)

I powered up the display for the first time, and nothing happened; no digits lit
up or anything. What’s wrong?

First, open the display containing the host driver (the driver connected to the
DataMaster 100 controller). Is the green LED labeled POWER illuminated? If not,
the driver is either not getting 24 V DC, or there is a problem with the power supply
circuit on the driver board. If there is 24 V DC on J17, and J17 is secure, the driver is
defective. If the POWER LED is illuminated, check the protocol and address
settings.
