TAG Heuer HL 670 User manual

HL 670 Data / Impulse
Transmitter set
User Manual
Version 09/2009

1. Global
The Set HL670 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.

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.
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 Accu is charging. The charge is completed as soon as
the green LED in on.

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 D is 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. 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)
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. System utility : TAG Heuer HL670 Configuration
Connect your device with the HL605-10 (delivered with the set) to your computer, run
the application. Turn on the system after pressing “Connect”.
This application is a free download from our Website : www.tagheuer-timing.com, It
enables you to configure the radio in different Baudrates:
2400, 9600 (Set by default), 38400, 57600,
115200 and 9600 bps with Flow control.

4. Software Update
With the Firmware (already used with the Chronoprinter 540 and the Minitimer HL440)
able you to change the transmission mode and Update your device.
For this application you need :
•The RS232 cable (HL605-10)
•A computer fitted with a D-Sub9 RS232 Output
•The software « Firmware.exe »
How to proceed
1. With the radio switched « OFF » connect the external power Connect the RS232
between your computer and the HL670
2. Run «Firmware.exe »
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 HL670 (hold down for 5 seconds « ON »
The HL670 will enter in a special setup mode
7. Until the file downloaded then, validate with « OK »
For each device, transmitter or receiver, two Software options are available :
oTAG Heuer Software (TH_Tx_Vxx / TH_Rx_Vxx)
This software is especially dedicated for the standard CP540 protocol and the
Minitimer. The 9600 with flow control Baud rate ensure that the frames are
correctly transmitted.
oChronelec Software (or transparent mode) (THbC_Tx_Vxx / THbC_Rx_Vxx)
This mode is especially for devices which need a data transmission with different
frame length. The data transfer is made until the device receives a blank
message within 50ms with a maximum frame length of 127 characters.
The transmission for 43 octets (standard CP540 frame) takes 125ms with 9600 bps.
The timeline is composed
- 35ms for the RF transmission. This time does not depend on the baud rate just
on the number of octets.
- 45ms for sending the frame
- 45ms for receiving the frame on the receiver

We can reduce this transmission time by increasing the baud rate from the receiver
and/or the transmitter. For example, the same frame length with 115200 bps (on both
sides) will only take 42ms.
Those devices may be used in a “Relay” configuration by plugging directly the
Receiver on another Transmitter (through the banana socket or RS232 connection).
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.

which the device will require a complete initialisation. To avoid this we
recommend that you always power up the device prior to connecting the
RS232/485 data cable.
