1. Global
The Set HL 675 is ideal for transferring Timing Data and Impulses.
Its 500mW emitting power and its licence free frequency range (869 Mhz) makes this device a powerful
and simple to use system.
Data / Impulse transmission system (500 Mw) which does not require a licence (free of use) in Europe
(ISM Band 869 MHz – REC 70-03).
Each Receiver can receive Impulses (simultaneously or not) from 4 Transmitters identified by the
function "CHANNEL" (1 to 4).
Up to 4 Teams can work (train) in the same area without disturbing each other thanks to the function
"TEAM" which offers the possibility to code each system (A, B, C, D).
It is also possible to use up to 16 transmitters with 4 receivers.
When the receiver is switched on, it is possible that one or more green LED’s are on before that the
transmitter(s) start to transmit. This detection system allows visualization of the quality of the
received signal, but also the possible interferences coming from other radio transmission systems. If it
is not possible to stop these interferences by moving the receiver, the transmission of Impulse cannot
be guaranteed.

1. Functions
1.1. The Transmitter :
1. IMPULSE Input for timing Impulse (Start gate, photocell – working / closing contact). Respect
the polarities.

2. POWER To switch on the receiver (press for 3 seconds on POWER).
The green LED is on.
To switch off the receiver, hold down SET and press POWER.
4. SET To program the TEAM (A,B,C,D) and to switch off the receiver.
Hold down SET during the changes.
5. TEAM To check the programmed TEAM.
To change the code, hold down SET and press TEAM.
6. CHANNEL To check the programmed CHANNEL.
To change the CHANNEL, hold down SET and press CHANNEL
7. TEST For testing the Impulse transmission only. The reception level will be displayed for
0.2 seconds on the receiver. You’ll also get an Impulse on the programmed
output.
8. TEST BATT To check the state of the battery. Press TEST BATT : The Battery level will be
displayed with the 4 LED’s for 2 seconds.
9. LED LED control panel which shows the programmed TEAM or CHANNEL. Also shows
the transmitted Impulse.
10. LED Shows the transmission mode : IMPULSE or DATA
11. CHARGE Charging status Leds.
The red led indicates that the battery is charging.
The charge is completed as soon as the green LED in on
.

1.2. The Receiver
1. IMPULSE Output for timing Impulse (Start gate, photocell – working / closing contact). Respect
the polarities.
2. DATA Female Sub-D 9 : RS232 Output
3. POWER To switch on the receiver (press for 3 seconds on POWER). The green LED is on.
To switch off the receiver, hold down SET and press POWER.
4. SET To program the TEAM (A, B, C, D) and to switch off the receiver. Hold down SET
during the changes.
5. TEAM To check the programmed TEAM. The green LED corresponding to the code A, B, C
or Dis on. To change the code, hold down SET and press TEAM.
6. LED LED control panel which shows the programmed TEAM or CHANNEL. Also shows the
Received Impulse.
7. LED Shows the transmission mode : IMPULSE or DATA
8. LED LED control panel which shows the Receiving Level and/or possible interferences
created by other radio signals.
9. BUZZER To enable or disable the Buzzer
10. TEST BATT To check the Battery status. The Level will be displayed with the 4 LED’s for 4
seconds:
- 4 LED’s on = 80-100%
- 3 LED’s on = 60-80%
- 2 LED’s on = 40-60%
- 1 LED on = 20-40%
- 1 LED on = 0-20% power remaining

2. Battery Charging
Each device has a Lithium-Polymer battery with supply 2100 mAh. Those batteries may be charged
with our charger HL540-10 or other 12V charger with a minimum of 800 mA.
For charging the battery we advise you to use our OEM TAG Heuer charger
Using another model may cause some trouble or harm the device.
-For charging, turn off the system.
- Connect the charger on the mains
- Plug the charger into the device
- The red LED will be on during the charge
IMPORTANT :
Always charge the devices by temperature above 32°F (0°C) and below 86°F (30°C)
The red LED lights during the charging process, when fully charged, the red LED shuts down and the
green LED will light on.
For a fully charged Battery it may take approx. 5 hours (for a completely discharged battery)
WARNING
Never connect the terminals of the battery in short-circuit.
To avoid keeping the battery pack fully loaded or completely discharged for a long period,
which reduces the lifespan of the battery. In the case of prolonged non-utilization of the
battery pack, it is necessary keep the system in a dry room, after a normal discharge.
In case of a reduced capacity of the battery pack, even after the load, leave the system ON a
whole night to obtain a complete discharge, then recharge the battery pack completely.
Renew the battery pack if the problem continues.
3. Software Update
With the Firmware (already used with the Chronoprinter 545 and the Minitimer HL440) able you to change
the transmission mode and Update your device.
New firware for the HL 675 are available free of charge on our website: www.tagheuer-timing.com
For this application you need :
The RS232 cable (HL605-10)
A computer fitted with a D-Sub9 RS232 Output
The software « FirmwareManager.exe »
How to proceed
1. With the radio switched « OFF » connect the external power Connect the RS232 between your
computer and the HL 675
2. Run «FirmwareManager.exe »

TAGHeuer Timin Page6/8
3. Select the correct COM Port
4. Browse and select the correct file (Rx/Tx)
5. Push START on the screen
6. Turn on the HL 675 (hold down for 5 seconds « ON »
The HL 675 will enter in a special setup mode
7. Until the file downloaded then, validate with « OK »
Hands on: Reinitialize your devices
If the systems are in a unknown mode, you can Initialise your system in the OEM
configuration (Channel 1, Team A, Buzzer On, Baud Speed 9600bps, Mode Impulse).
Push simultaneously SET and TEST BATT for 3 seconds.
All LED’s will flash and the system will beep until it is reinitialized.

5. Special pinout for Displays HL980 and HL960 / 990
6. Special Pinout for TX activating
Our radios are equipped with a PNP Transistor on their output.
This is an IT Standard which also allows us to ensure good autonomy.
Some devices only work with an RX pin and Ground. In order to activate this transistor and initiate the
external data from the radio you need to energise the Transistor with an external power supply or a
charged condenser.
