Check to make sure that the protocol plug is loaded in J20 of the host driver. The
protocol plug should be installed only on the host driver (the driver connected to the
DataMaster 100 controller.)
If the host driver has power and the proper protocol and address settings, it will
always display something on power-up (it may be just an error code). If this does not
resolve the problem, the driver is probably defective. You can try swapping the host
driver with one from a different display. Make sure that the host driver always has a
protocol plug installed on J20.
Q.
My sign is displaying “Ex” (x is a number). What’s wrong?
A.
The driver displays error codes for common problems; refer to the Troubleshooting
section of the manual to resolve the problem.
Q.
My sign is displaying garbage. What’s wrong?
A.
Most likely the protocol and/or address plug settings are incorrect. The protocol plug
should be installed in jack J20 only on the host driver (the driver connected to the
DataMaster 100 controller). (Refer to the Power and Signal Connection section of
the manual.)
Q.
I don’t want to show __ (°C/°F/time) on my Time & Temp display. How do I
remove this?
A.
Use the DataMaster 100 controller to set the hold time for this item to 0.0.
Q.
When I try to set the hold times on my Time & Temp display to less than 1.1
seconds, it doesn’t work. Why?
A.
DataTime displays with driver software versions earlier than 2.0 did not support hold
times of less than 1.1 seconds. Versions 2.0 and newer do not have this issue.
Q:
I just connected my DataTime display, and instead of showing temp, it shows an
error message. What's wrong?
A:
Refer to Drawing A-166883 for temp sensor jumper settings and LED indicator
information. Refer to Drawing A-166216 for the 4-column MASC LED driver (or
appropriate 8- or 16-column driver specifications) for troubleshooting information.
The CAN RX and CAN TX LEDs should blink once every few seconds. If both
LEDs are on constantly, suspect the wiring between the MASC LED driver and the
temp/light sensor.
Q:
I have a multiple line display and all lines of the display show the information
set on the first line. How do I get the correct information on each line of the
display?
A:
The line number for the display is set using address plug J19. All displays ship with
an address plug that defaults to Line 1. The install kit includes a set of 12-pin Mate-
N-Lok
™
plugs that are labeled with the line number of the display driver to which
they should be installed. If a driver is located inside a display on a line other than
Line 1, remove the Address plug and install the corresponding plug to the line of
price data you would like to show.
