Repeaters
The repeaters will automatically power on when power is applied. Press the pushbutton on their
front panel to activate the LEDs as they will turn off eventually to save power.
The information delivered by the LEDs on the MDTs and the Repeaters are identical and
described below:
Turn ON or Off (MDT only):
- Press & hold button until LED blips off, then release.
Power-up LED Flashing:
- Listening for DCAP or Repeater: LED flashes slowly
- Trying to Connect to DCAP: Flashing changes from slow to fast
- Successful Connection: LED stays solid for 10 seconds.
- If NOT successful, LED goes out without the 10 second on
Check the status of an MDT or Repeater by tapping the button
- Unit is OFF: Two flashes after button is released
- Unit is Asleep and NOT connected to Network: One flash only
- Unit will wake up within one hour and try to re-connect to
Network. This is usually an indication of poor placement or
inadequate Repeater coverage.
- Unit is Connected and operating normally: LED on for 10 seconds
- Green is good link, Orange an OK link, Red is poor link
Reset Count (MDT Only): Press and hold button until power-up flashing sequence starts (12-
15 seconds)
MDT to Meter wiring
Refer to our many wiring diagrams on our web site for wiring instructions from the many
different meters available.
5. Repeaters and MDT Devices Placement
a. Repeaters Backbone
With the DCAP Unit powered up, the repeater backbone should next be placed. Repeaters turn
on automatically when power is applied. Their LEDs will turn off after a few minutes to save
power but can be turned back on by pressing the pushbutton on the front panel. Start with
units closer to the DCAP/AP, and use the LED feedback indication to verify the range is
acceptable. At first just the minimum numbers of repeaters can be placed, and it is necessary
that they be within range (solid 10 second LED “flash” when button pushed) for the backbone
to be reliable. Repeater to Repeater (or DCAP) range in open field scenarios is in excess of 1/2
mile, however building construction materials, terrain, and poor location choices can reduce this
down to hundreds of feet or less.
Warning: All radio devices should be placed at least 8 inches (20 cm) away from people in
order to minimize RF exposure.
