Bodet DHF V2 927241 Installation manual

The HF (869MHz) radio transmitter sends the time code that it receives from the master clock.
The 869 MHz radio waves go through building walls: the coverage is about 100 to 200 metres and depends on
the number, structure and thickness of the walls. The DHF wireless time distribution uses a secured digital
transmission to avoid interferences with other transmissions.
In case of complex installation or when the reception is difficult, a secondary transmitter allows the coverage area
to be increased up to 1.5 km.

What
to do
if …
?
Some clocks are not synchronised.
Make sure that the main transmitter and the slave clocks are in
the “Init” mode. Verify that the secondary transmitter red LED is
blinking regularly. Increase the transmitter power. See diagram
(7A).
Transmission power set to the maximum, some clocks are still
not synchronised. Add a repeater (See 2).
You are close to an existing wireless clock system. See to it that the secondary transmitter is paired to the proper
main transmitter, see (5).

Start up instructions
Mount the repeater in the area covered
by the transmitter. Under no
circumstances the transmitter should be
directly mounted on a metallic surface. The DHF repeater V2 (ref.: 927241) enables to extend an area non
covered by the main DHF transmitter.

Connect the 230V (A) and secure the
powercable with the tie-wrap (B). Apply
the power.
5The DHF repeater must be
paired with the DHF transmitter in order to
work properly:
- Check that the « Init » mode yellow LED blinks. If
not, set up again the repeater in « Initialization”
mode (part 6).
- Set up the main transmitter in “Init” mode.
- Once the signal of the main transmitter is
transmitted, the « Init » mode yellow LED is OFF
and the DHF transmission red LED is ON.

Status of the DHF repeater at the first start
up.
- Power DIP (D) in position MED (125W).
- Power setting LED (C) ON (125 mW) on,
- INIT mode yellow LED (E) blinks (waiting for
the initialization of the main transmitter),
- DHF transmission Red LED (G) OFF.

In “initialisation” mode, the LED (E) is
on. To switch the repeater back in Init
mode, short the two pins (F) for 3
seconds.

You can adapt the transmission power
with two DIP switches (D). LEDs (C) allow
you to check your setting.
If some clocks are not synchronised, increase the
transmission power.
The DHF repeater has a buzzer (H). It can be
activated from the master clock Sigma to help in
localizing the DHF repeater.
