Operation
This unit is extremely easy to use and incorporates three jumper sets, JP1, JP2 and JP3.
The PCFW-104 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 PCFW-104 Radio Modem.
2. Disconnect power before removing or inserting the PCFW-104 Radio Modem.
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. It is recommended that the supply have a minimum of 1.0 Amps for
the 12 VDC internal or 8-30 VDC external source.
