Installing the Hardware
Before installing the board, carefully read Chapter 3 and Chapter 4 of this manual and configure the board
according to your requirements. The SETUP Program can be used to assist in configuring jumpers on the
board. Be especially careful with Address Selection. If the addresses of two installed functions overlap, you will
experience unpredictable computer behavior. To help avoid this problem, refer to the FINDBASE.EXE program
installed from the CD. The setup program does not set the options on the board, these must be set by jumpers.
This multi-port serial communication board uses software-programmable address ranges for each UART,
stored in an onboard EEPROM. Configure the address of the EEPROM using the onboard Address Selection
jumper block, then use the provided Setup program to configure addresses for each onboard UART.
To Install the Board
1.
Install jumpers for selected options and base address according to your application requirements, as
mentioned above.
2.
Remove power from the PC/104 stack.
3.
Assemble standoff hardware for stacking and securing the boards.
4.
Carefully plug the board onto the PC/104 connector on the CPU or onto the stack, ensuring proper
alignment of the pins before completely seating the connectors together.
5.
Install I/O cables onto the board’s I/O connectors and proceed to secure the stack together or repeat
steps 3-5 until all boards are installed using the selected mounting hardware.
6.
Check that all connections in your PC/104 stack are correct and secure then power up the system.
7.
Run one of the provided sample programs appropriate for your operating system that was installed
from the CD to test and validate your installation.
Installing COM Ports in Windows Operating Systems
*NOTE:
COM boards can be installed in virtually any operating system and
we do support installation in earlier versions of windows, and are very likely to
support future version as well. For use in WinCE, contact the factory for
specific instructions.
Windows NT4.0
To install the COM ports in Windows NT4 you’ll need to change one entry in the registry. This entry enables IRQ
sharing on multi-port COM boards. The key is
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Serial\
. The name of the value is
PermitShare
and the data should be set to
1
.
You’ll then add the board’s ports as COM ports, setting the base addresses and IRQs to match your board’s
settings.
To change the registry value, run RegEdit from the START|RUN menu option (by typing REGEDIT [ENTER] in
the space provided). Navigate down the tree view on the left to find the key, and double click on the name of the
value to open a dialog allowing you to set the new data value.
