destroyed when the power to the card is applied. This is due to the fact that the input current biases the IC so that it acts as a forward biased diode on power-up. This type of failure is typical on serial interface chips. Hot insertion Plugging cards into the card cage with the power on will usually not cause a problem. (MicroBee urges that you do not do this!) However, the card may be damaged if the right sequence of pins contacts as the card is pushed into the socket.
OVERVIEW . . . . . . . . . . . . . ............................................................................................. . . . . . 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 specifications calls for a height of 0.4 inches.
TECHNICAL SPECIFICATIONS . . . . . . . . . . . . . ............................................................................................. . . . . . Baud Rate The PCFW-104 is fully 16C550A compliant and supports software selectable baud rates of 300, 1200, 2400, 4800, 9600, 19.2K, 38.4K, 56K and 115.2K. Environmental -40° to 85° C operating. -50° to 90° C non-operating. RH 5% to 95%, non-condensing. Power Specification 5V +/– 5% at 50 mA max. 12V +/- 5% at 500 mA, Radio powered by PC/104 Bus.
98, ME, NT, 2000 and XP may limit your IRQ selection without aftermarket drivers. This is usually not required unless all IRQ’s supported by the OS are already allocated. Note PC/104 CPU manufacturers vary in implementation of the interrupt interface. Most use pullups on the interrupts. This allows a board to drive low or tristate float high the interrupt lines preventing damage if two boards conflict. The PCFW-104 uses the tristate scheme. On a few motherboards the manufacturers use pulldown resistors.
Radio Power In order to provide maximum flexibility for the user the PCFW-104 allows for powering of the Radio Module from either the PC/104 Bus 12 VDC supply or an external 6-30 VDC source. PC/104 Bus Power Place jumper JP3 in the INT position (jumper nearest PC/104 Connector). The radio module is now powered from the PC/104 bus an no further connections are required. It is important to be sure that the 12 VDC bus power source has sufficient current to supply the radio.
Testing Installation NOTE Refer to the FreeWave Radio Users manuals for proper radio operation and setup. Once the unit is installed it is recommended that the unit be tested using a simple communications program such as Hyper Terminal under windows. Open the communications program and select the proper COM port. Set the communications parameters to 19,200 Baud, 8 Bits, No Parity, 1 Stop Bits (19200,N,8,1) and press the setup button. The FreeWave Setup Menu should come up on the screen.
