Chapter 1: Installation The WINCOMM4 board can be installed in any of the PC expansion slots, except J8 on the original IBM XT and portable. Be sure to set the address and jumper options before installation. Remove the PC case, remove the blank metal slot cover, and insert the board. Replace the screw, replace the cover, install the “spider cable”...
Chapter 2: Address Selection Each serial port on the WINCOMM4 board occupies 8 consecutive I/O locations. A dip switch is used to set the base address for these locations. Be careful when selecting the base address as some selections conflict with existing PC ports. The following table shows several examples that usually do not cause a conflict.

Switch Position Address Line Example: 300 Hex Switch Note - that setting the switch ON or CLOSED corresponds to a “0” in the address, while leaving it OPEN or OFF corresponds to a “1”. Page 2-2 Manual Number: 00750-004-14...
The board contains several jumper straps for each port which must be set for proper operation. Port Enable/Disable Each port on the WINCOMM4 can be enabled or disabled with switch position 8 on the dip switch. The port is enabled with the switch “ON” and disabled when “OFF” or “OPEN”. If any port is disabled, be sure to also disable the interrupt request for that port by removing the IRQ jumper (see below).

Set the jumpers to "S" for shared interrupt mode on all blocks sharing an IRQ except one. Set that port block for "M". This provides the pull-down resistor circuit that makes sharing of IRQ's possible. If you are using morethan one WINCOMM4 or a compatible card in a BUS, you Page 3-2...

"M". This example shows all four ports sharing a single IRQ. Set the jumpers to "S" if you are using more than one WINCOMM4 in a BUS or you wish to completely remove the pull-down resistor for hardware compatibility. Setting the board in this configuration when it is not accompanied by a pull-down or pull-up resistor will prevent the ports from triggering an interrupt.
The WINCOMM4 provides 4 additional serial ports for terminals, modems, printers, etc. The WINCOMM4 can be configured as COM1: through COM4:, or any other I/O address (up to 3FF HEX), providing a low cost means of expanding the number of serial ports on your PC.
