Replacement Hot insertable/removable. There is no risk to damage hardware, but
a reset is required.
Test Automatic test of the access of the card by the CPU
(See LED ‘CS’ below)
LED
CS Card Selection: the card corresponds to a card declared in TWinSoft.
ER Error: The type of the card does not correspond to the one declared in
TWinSoft.
GPS Receiver
General L1 (1575 MHz), C/A code, 12 channels, continuous tracking receiver
Precision: position
clock

500 ns (SA On)
Acquisition: Cold start
Warm start
< 60 sec
< 3 sec
Antenna connector Active antenna: SMA compatible
Power delivered by the card : 3 to 3.6 VCC
Synchronization
Internal Generates an internal clock signal every 1 ms (precision 200 µs)
Output Open collector, to synchronize to other TB
OX
MS
Frequency : 1 sec.
Precision : 200 µs.
To CPU-16 Synchronization from the digital input
Tick of the CPU-16 : 10 ms (used for time stamping)
Global precision : 25 ms
To CPU-32 Synchronization from the BUS
Tick of the CPU-32 : 1 ms (used for time stamping)
Global precision : 1 ms
LED RxD, TxD, Lock (validity of the GPS signal received)
Output 1 Hz
RS232 – RS485
Mode RS232 or RS485 (no simultaneous use of both modes)
Isolation No isolation. Gnd is linked to earth by internal connection
RS232 Signals: RxD, TxD, CTS, RTS, DTR, DSR, DCD, RI
Connector: 9 pin Sub-D (male)
RS485 • 2 wires (A+ and B-) for multi-points connection
• No need for termination resistor (
failsafe bias
resistors included:
pullup and pulldown resistors which assures a logical level TRUE
when A and B are open or in short circuit)
• Number of slaves: 256 (if RS485 technology of slaves allows it too)
• Screw connector: female with a step of 5.08 mm
