The PCFW-104 PC/104 FreeWave Data Radio is a PC/104 Bus Compliant 8 BIT interface that
allows the FreeWave Model FGRM-511X005 900 MHz data radio to be easily installed on any
PC-104 stack.
The PCFW-104 is fully PC/104 compliant in all aspects EXCEPT height. The PC/104 specifica-
tions calls for a height of 0.4 inches. The unit exceeds the recommended height by approxi-
mately 0.200 inch and is due to the RF Shield.
Once the unit is configured and installed it is treated like any other serial port on the stack.
In other words, if it is configured for an address of 3F8 and IRQ 4 then it is as simple as using
any device on COM 1.
The interface supports baud rates up to a maximum of 115,200.
The unit includes the 16 bit 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 PCFW-104, be-
ing an 8 BIT interface, does not require a 16 bit ISA card be prior to the radio unless operation
requires IRQ 10, 11, 12 or 15.
For more information on the PC-104 ISA bus please refer to the PC-104 specification at:

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:
Ground yourself before handling the PCFW-104 Radio Modem.
Disconnect power before removing or inserting the PCFW-104 Radio Modem.

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.
