STEP I - Establish communication between the remote and the TIU
A. Power up both the DCS Remote and the TIU by turning on a transformer hooked to
the fixed input 1 channel and pressing the S5 On/Off button on the remote.
B. Press the READ button on the remote.
1. If the remote says FOUND TIU ADDRESS # WITH # AIU BOXES
CONNECTED that means that your remote is communicating with the TIU -
Proceed to STEP II.
2. If the remote says TIU ADDRESS # NOT FOUND that means that your
remote is not communicating with the TIU - keep following this step.
a. Power up the TIU and count the number of times the red LED
blinks, this number is the actual address of the TIU. Compare that
number to the TIU address that the remote did not find.
1. If the numbers do not match then you must add the correct TIU address in
to the remote and delete any unused TIU addresses that may be in the remote
already. After you're finished, power up the TIU and the remote and press the
READ button again.
· If the remote finds the TIU then proceed to STEP II.
2. If the numbers match but the remote still will not find the TIU that means
you most likely have a loose RF Module in either the remote or the TIU. Open
up both and make sure that the RF Modules are pushed all the way in to their
respective sockets. After you finished power up the TIU and remote and press
the READ button again.
a. If the remote finds the TIU proceed to STEP II.
b. If the remote still does not find the TIU that means that you most
likely have a bad RF module in one or the other. If available use a
known good DCS system to check which RF module is bad and order
the correct RF module from us.
3. If the red LED does not light at all then check for a blown fuse in the TIU.
4. If the red LED in the TIU comes on but does not blink at all that usually
means that the software was not loaded correctly in the TIU, try re-loading the
software.
