Emit Time Station
ETS 2
rev. 2.1 - 11.11.2020
This user’s guide describes the use of Emit Time Station ETS2, which is used to
register emiTags.
The user’s guide firstly describes the ETS2’s various functions and then explains
how the enclosed extra equipment is to be connected and used.
urthermore we take a look at the ETS2’s menu system and go through the
menu choices. In the menu you may set the clock, the station’s code, the
display’s appearance, the protocol, the range of the signal, etc. We also discuss
how to use the menu system for troubleshooting and explain recommended
procedures when problems occur.
To process data from the ETS2 and to generate the result lists you need a PC
program which is compatible with emiTag/ETS2.
All available circuit diagrams, illustrations and specifications of extra equipment
are included in the “Emitag - koblingsskjema” manual. Not all of them are equally
relevant, but we prefer to include too much rather than to omit information that
may be of interest for some. Spare parts and extra equipment are marked with
Elfa’s supply numbers and may be ordered directly from Elfa (our supplier) if you
wish to install the parts yourself. Some of the supply numbers from Elfa may
however be outdated. The safest option is to buy the parts directly from Emit,
installed and ready for use.
The last part of the manual explains how to update the firmware in the ETS2
using the 'eUpdate' program from Emit, and ETS2's technical specifications are
displayed on the last page.
We have chosen to mark ‘input’ (connection ports) with green, ‘light emitting
diodes’ with blue and ‘key text’ with red to make it easier to distinguish between
the different functions.
ETS2 4G is the first transponder-decoder that is IS-approved for use in all IS-
sports, and for all levels. In order to be IS-approved a printer has been added.
In addition the hardware has been revised and fine-tuned to live up to IS's
requirements on resolution, accuracy and drifting. This includes a precision of up
to 31 uS1/1000000 seconds on the printout, if the 'Start/Sync' or ' inish' inputs
are used.
The ETS2 replaces the traditional clock and registers the time when the emiTags
pass the eLine loop, internal or external. The start-time and/or finish-time can
also be registered using an external start gate and/or photo cells. This enables a
timing resolution up to 1 uS accuracy ( 1/1000000).
The competitor’s tag ID and time are transmitted from the emiTags and back to
the ETS2 via an internal radio antenna. The data is saved locally before it is
transferred to a PC via USB, RS-2 2, RS-485 or GPRS.
The ETS2 and the emiTags may be used for timing in various sports, including
cross country skiing, biathlon, orienteering, ski orienteering, cycling (road racing,
time trials, off road, track cycling), running, triathlon, etc.
You may control the ETS2 from a computer or with the built-in keyboard, with six
variable menu keys and a numeric keyboard. The ETS2 has five LEDs (light
emitting diodes) and a graphic display which shows current information. The
LEDs change colour depending on the status of the event it is connected to.
You may use the ETS2 with the internal eLine loop or with up to two external
eLine loops. It is also possible to use Emit's 'StandUp Loop', if you prefer to have
a loop on the side of the course/track. The accuracy is better when you use two
eLine loops (approxiimately 1/100 second depending on the speed). When you
use one eLine loop the accuracy is about 1/10 second. Note that the range of the
internal eLine loop only is three metres.
Equipment included:
The ETS2 is delivered with the following equipment included:
Two eLine loops. The loops covers a twelve meters wide track.
220 V power cable
USB cable
This user’s guide
The ETS2 has several ports for connecting external equipment on top of the unit,
under the lid. These include (from the left to the right seen from the front):
'GPRS' - or connecting external GPRS antenna
'Finish'- Double banana plugs for connecting a photo cell
'Start/syn .'- Double banana plugs for connecting a start gate
'RS-232'- RS-232 (serial) port to PC
'USB'- - USB port to PC
’RS-485’- or transferring data via RS-485
'Loop 1'- or connecting external eLine loop 1
'Loop 2' - or possible connecting of external eLine loop 2
'Antenna' - or connecting an external radio antenna
'110-230V'- or connecting a 220V power cable
Charging the built-in batteries:
The ESD1 has eight built-in rechargeable batteries 9Ah NiMH. You charge the
batteries by connecting the included power cable. Make sure that the charging
switch is set on ‘ON’. When the charger is connected, the LED marked ‘Charge’
will be lit. Charge the ETS2 until the LED turns green. The process usually takes
about eight hours if the batteries were flat when you started. If you want top
charged batteries, you may continue the charging for 1 or 2 hours more. The
batteries will not be damaged by being connected to the charger for a longer
period of time.
The LED marked 'Battery' indicates the remaining battery capacity. A red light
indicates a battery capacity of less than 30%. An orange light indicates a battery
capacity of 30--60%. A yellow light indicates 60-90% capacity, and a green light
indicates that the battery capacity is more than 90%.
Surroundings
The ETS2 is not waterproof, so make sure that no water seeps into the
connection ports on top of the unit. You may use the ETS2 in temperatures as
low as -20 °C, and the unit may be placed outside in rain and snow - as long as
the lid is locked.
CONNECTIONS
The radio antenna
If you wish to use an external radio antenna, it should be connected to the port
marked ‘Antenna’ You do not need an external antenna as long as the ETS2 is
placed no more than five meters from the track, but it may be wise to use an
external radio antenna if the distance is longer than this. If that is the case we
recommend to use a Yagi-antenna, which is sold separately. The Yagi-antenna
should be mounted 5-10 meters after the finish-line, and be pointing towards the
finish line.
External eLine loops
You should use an external eLine loop if the track is wider than 3 metres or if the
competitors pass more than 3 metres from the ETS2. Mill off a track for the loops
with a chain saw or some other suitable tool if the loops are to be placed in the
snow. If the surface is asphalt or other solid ground, the loops must be taped and
secured under mats suitable for the purpose. Make sure that the loops are stable
and lie safely, so that they do not disconnect and cause damage!
Place the loop in the track and run the cable to the ETS2. The eLine loop cable
has a black plug and is to be connected to the 'LOOP 1' port on the ETS2.
When you use two eLine loops you must remember that the blue loop ALWAYS
must be placed in front, while the grey loop ALWAYS must be placed at the
back. The grey eLine loop’s cable has a colourless plug and is to be connected
to the port 'LOOP 2' on the ETS2.
Signal ’contagion’
Note that the wireless signals from the eLine loops may have a range of several
meters. It is recommended to establish a ‘security zone’ of about 3 - 5 meters on
both sides of the loops, and about 5 meters parallel to the race direction, to avoid
errors with wrongly registered competitors passing in another track.
eLine loops for cycling races
In cycling and other sports where the competitors pass the finishing line in high
speed, you must increase the distance between the loop’s wires from 120 cm to
200 cm at the finish.
The LED’s marked 'LOOP 1' and 'LOOP 2' are green when the eLine loop is
connected and functioning. A red light indicates that the eLine loop is
disconnected or not functioning. An orange light indicates that the eLine loop was
disconnected when the power was switched on, or that the connection has been
broken, but is now OK. A blue light indicates that no connected antenna is
needed. This may be the case when you wish to use the ETS2 with only one
eLine loop. In such cases you connect the eLine loop to 'LOOP 1', and the
'LOOP 2' LED will be blue.
Connecting ETS2 to a
PC using USB
Connect the ETS2 to a PC
with the enclosed USB cable.
The ETS2 and the PC should
be switched on before
connecting them to the USB
cable. Connect the cable to
the port marked 'USB' on the
ETS2. Connect the other end
of the cable to an available
USB port on the PC.
The first time you connect the ETS2 to a PC with an USB cable, you might have
to install two drivers; ‘USB Serial Converter’ and ‘USB Serial Port’. Normally this
is done automatically, depending on the PC's operating system.
A virtual com-port is installed and appears in the Windows control panel, when
you connect external USB-equipment. When the equipment is disconnected (or
shut off), this com port will not be shown in the control panel. The com port will
often be shown as ‘com3’ or ‘com4’, depending on how mange com ports that
already are installed in the PC. If you wish to keep the same com port number
every time, you must connect the ETS2 to the same USB port every time.
Using the RS-485 port
Data may be transmitted long distances from the
ETS2 by using the RS-485 port. When you use this
port the cables may be several hundred meters long,
but you have to convert the signal to RS-232 or USB
in the other end of the cable. We have chosen
converters from Moxa Inc. for this use, because they
are among the best and the most stable converters
one can get. We mostly supply Moxa Uport 1450I (4
ports, isolation protection), but we can also provide
Uports with 1, 2 and 8 ports. We do not recommend
serial converters that doesn't have isolation protection,
even if they are much cheaper.
Using photo cells
When using photo cell(s) at the finish you
must connect to the double banana plug
marked ' INISH'. When the ETS2 is
connected to photo cell(s), it will use the
photo cell as finish time and match this time
to the correct tag number.
Using a start gate
When a start gate is used to register start
times, the start gate must be connected to
the input marked 'START/SYNC'.
Synchronising several ETS2
Several ETS2 can be synchronized using
the 'START/SYNC'-input, by short-circuiting this contact (with a switch or a short
cable). All of the ETS2's to be synchronized must be connected to the same
cable AND they must all be in the 'Set Clock'-mode. Use the numeric keys to
set a valid time between 00:00:00 and 23:59:59 (on all ETS2's to be
synchronized). Start the clock simultaneously on all the ETS2's by short-circuiting
the cable connected to the 'START/SYNC'-inputs.
To check that all ETS2's have been synchronized correctly, short-circuit the cable
once more and check that the time registered is identical on all ETS2s. The time
is printed and shown on the display:
F0-1 09:00:13.954672
USER INTERFACE
The display of the ETS2 has seven available lines and up to 20 symbols. Three
keys on each side of the display control the various menu choices. In addition the
keypad has numerical keys and comma, plus four set keys.
'Menu' - in or out of menu modus
'Clear' - deletes the last symbol or leaves the menu
'On/Off' – turns on or off the ETS2 (hold for five sec. to turn off)
'Enter' - accepts choices
Operation mode
Start the ETS2 by pressing the 'On/Off' key. Two seconds later you will see
version number, battery status, radio status and clock. You will also hear clicking
sounds from the unit – this is the eLine loops’ drivers, which are automatically
adjusted every time the ETS2 is turned on. When the start-up procedures are
done (ca. 5 sec.) the display will show what time it is (HH:MM:SS), how many
tags that are registered (M=0) and to which code the ETS2 is set (C=100). If a
4G modem is connected (and enabled) the display will show '4G'next to M=0.
If an external eLine loop is not connected, you will be asked the following
question:
Answer ’'Off' if you don't want to use a loop with the ETS2. Choose 'Internal’ if
you want to use the internal eLine loop. Note that this loop is mounted at the
bottom of ETS2, and the range is merely three meters. Answer ‘External’ if you
have connected an external eLine loop to the 'LOOP 1' port on the ETS2.
Check that the LEDs for loop1 og loop2 have the correct colour (see page six for
details) and that all cables are properly connected.
The ETS2 is now in operation mode and is ready for use.
MENU SYSTEM
The menu system is used to customize various settings for the ETS2. In this
section we'll go through all menu items and explain how they work.
Press the 'Menu'-button to enter the main menu. Pressing 'Menu' again brings
you back one step in the menu system - and if you are in the main menu it will
return to operating mode. Pressing 'Clear' always brings you back to operating
mode.
Main menu (main menu)
In the main menu you have six choices: setting the clock, starting a new race,
displaying technical information, setting the unit's code, changing various
settings, and spooling data. Some of the menu choices leads to a sub-menu,
Set Cloc (main menu – set cloc )
Use the numeric keys to set a valid time between 00:00:00 and 23:59:59. Start
the clock by pressing 'Enter' or by short-cutting the 'START/SYNC'-input.
New Race (main menu – new race)
The 'New Race'-function resets the counter for registered emiTags and empties
the flash memory in the ETS2. The unit is now ready for use in a new race.
It is strongly recommended to do this before every race.
Info (main menu – info)
The info menu displays various information for the ETS2. There are five menu
choices in the info menu; general, power, versions, modem and print. The four
first menu choices lead to a sub menu. Press the 'Print'-key to print all this
information on the internal thermal printer.
General (main menu – info – general)
The general info menu shows which code the ETS2 is set to on the first line. The
second line shows how many passings it has recorded in the current session.
The serial number is shown on the third line, while calibration status is shown on
the forth line.
Power (main menu – info – power)
The power info menu shows how much battery capacity that is left on the first
line. The second line shows how many volts the battery has, while the third line
