deep. This means that instead of an interrupt generated every 15 characters one could be

generated only once per message greatly reducing overhead on the host processor to handle

interrupt servicing.

The unit incorporates the 16 bit PC/104 ISA connector so 16 bit devices can be placed on the

stack after the radio. Also interrupts 10, 11, 14 and 15 are accessed thru this connector. The

MBS-GPS-SS2-5HZ, being an 8 BIT interface, does not require a 16 bit ISA card be prior to the

radio unless operation requires IRQ 10, 11, 12, 14 or 15.

For more information on the PC-104 ISA bus please refer to the PC-104 specification at:

Caution:

The MBS-GPS-SS2-5HZ contains static sensitive CMOS components. The greatest danger

occurs when the card is plugged into the PC/104 stack. The card becomes charged by the user

and the static discharges to the I/O bus from the pin closest to the card connector. If that pin

happens to be an input pin, even TTL inputs may be damaged. Follow sound ESD practices!!!!

To avoid damaging your card and its components:

1. Ground yourself before handling the MBS-GPS-SS2-5HZ GPS Module.

2. Disconnect power before removing or inserting the MBS-GPS-SS2-5HZ GPS Module.

OPERATING PRECAUTIONS

Be sure that your PC/104 stack and/or power supply has sufficient current to supply the radio at

the specified power setting. For use with an active antenna 12V is recommended although 5V is

sufficient. Please refer to Jumper setting for Active Antenna Power Selection.
