W-E-B Telemetry Technical Manual Introduction
Handling your board safely
Anti-static handling
This board contains CMOS devices that could be damaged in the event of static
electricity discharged through them. At all times, please observe anti-static precautions
when handling the board. This includes storing the board in appropriate anti-static
packaging and wearing a wrist strap when handling the board.
Batteries
The W-E-B Telemetry board contains a Lithium battery to maintain the configuration of
the GPS unit, if present.
Do not short circuit the batteries or place on a metal surface where the battery
terminals could be shorted. During shipment the battery is isolated from the
boards circuitry and should be connected before using the board. Please refer
to the link section of this manual for details.
Dispose of used batteries according to the manufacturer’s instructions and
local ordinances. Do not incinerate, crush or otherwise damage the batteries.
The batteries are non-rechargeable. There is a danger of explosion if a lithium
battery is recharged or incorrectly replaced.
The Lithium battery on the W-E-B Telemetry base board has a life expectancy
of 5 years. This battery should only be replaced by qualified service
personnel.
Packaging
Please ensure that should a board need to be returned to Arcom, it is adequately
packed, preferably in the original packing material. If the original packing material is not
available, return the board in an anti-static bag contained within a box that provides
suitable protection.
Electromagnetic compatibility (EMC)
The W-E-B Telemetry board is classified as a component with regard to the European
Community EMC regulations, it is the responsibility of the end user to ensure that
systems using the board are compliant with the appropriate EMC standards.
Arcom EMC tests of the W-E-B Telemetry board have shown that the RF emissions of
the board are well below standard international EMC limits and that it is unlikely to
contribute significantly to the RF emissions spectrum of any system in which it is used.
The optional wireless modules catered for by the W-E-B Telemetry board all have full
regulatory approval from the appropriate agencies.

W-E-B Telemetry Technical Manual Detailed hardware description
W-E-B Telemetry board footprint
The board is 100mm (3.93") by 155mm (6.10") and is 1.6mm (63 thou) thick.
Power supply requirements
The board is designed to accept a 10V to 30V DC power supply, nominally 12V DC.
Power conditioning
The input supply lines are protected using re-settable surface mount fuses. These fuses
can only be reset by power cycling the board.
The PCB also provides protection for reverse voltage and transient voltages to comply
with ETSI EN 301 489-1 V1.4.1, ISO 7637-1 and ISO 7637-2.
On board EMC filtering minimizes conducted noise.
Switch mode power supplies
On board DC/DC converters provide the necessary power rails:
+5V, 2.5A max. •
•
+3.6V, 2.5A max.
•
+12V, 250mA max.
•
-12V, 150mA max.
•
+1.8V, 100mA max (see Sony Ericsson modem module).
Network interface
A 10/100Base-T Ethernet connector is mounted on the front edge of the PCB to allow
direct mounting to a front panel. The RJ45 connector incorporates activity and speed
LEDs. The network connection is provided by the PC/104 processor card and is
connected to the board by a standard RJ45 cable.
Serial interface
A dual port male DB9 connector is mounted on the front edge of the PCB to allow direct
mounting to a front panel. The RS-232 serial connection is provided by the PC/104
processor card and is connected to the board by a standard 20-way IDC ribbon cable.
PC/104 bus support
The board includes an 8bit PC/104 slave interface conforming to IEEE996.1. The
module includes a 16bit connector to accommodate connections for additional interrupt
lines.

W-E-B Telemetry Technical Manual Detailed hardware description
Power supervisory circuit
A supervisory circuit monitors the DC input supply. This signal creates an interrupt
(Power Fail) to indicate an occurrence of the DC supply voltage falling below 8V DC.
The number of interrupt resources required is minimized by concatenating several
interrupts into a single signal. This interrupt is concatenated with the Ignition Sense
interrupt.
Ignition sense circuit
A supervisory circuit monitors an auxiliary (Ignition) input supply. This signal creates an
interrupt (Ignition Sense) to indicate an occurrence of the DC supply voltage falling
below 8V DC and rising above 8V DC.
The number of interrupt resources required is minimized by concatenating several
interrupts into a single signal. This interrupt is concatenated with the Power Fail
interrupt.
Dual UART 16C552
Two on board 16C550 compatible serial ports support optional wireless modules, whilst
a parallel port supports digital I/O.
Modem ON / OFF control signal
When power is initially applied to the board, the modem modules are in a low power/off
state. Toggle the ON / OFF control signal to turn the modules on. The ON/OFF signal is
provided by the parallel port (bit 3). The address of this signal is Base address (as
selected at LK1) +10H.
To turn the modem module on, follow these steps:
1 Apply power to the board.
2 Write a ‘1’ to bit 3 of parallel port. The status of the signal is (on).
3 Wait 10ms then write a ‘0’ to bit 3 of parallel port. The status of the signal is
(off).
4 Wait 600ms, then write a ‘1’ to bit 3 of parallel port. The status of the signal is
(on).
To turn the Motorola modem module off, write a ‘0’ to bit 3 of parallel port, (off).

W-E-B Telemetry Technical Manual Detailed hardware description
To turn the Sony Ericsson / Siemens modem module off, follow these steps:
1 Write a ‘1’ to bit 3 of parallel port. The status of the signal is (on).
2 Wait 10ms, then write a ‘0’ to bit 3 of parallel port. The status of the signal is
(off).
3 Wait 1000ms, then write a ‘1’ to bit 3 of parallel port. The status of the signal is
(on).
Status LEDs
Four status LEDs are provided, in a traffic light stacked arrangement. This is positioned
on the front edge of the PCB to allow direct mounting to a front panel:
A green LED provides visual confirmation of power. •
• A red LED and two yellow LEDS are user controlled.
The LEDs are accessed through the parallel port (bit 0 red; Bit 1 yellow; Bit 2 yellow).
The address of these LEDs is Base address (as selected at LK1) +10H.
Write a ‘1’ to the appropriate bit to turn the LED off.
Write a ‘0’ to the appropriate bit to turn the LED on.
