INDUSTRIAL COMPUTER SOURCE WINCOMM4 Card Type Multi-I/O card Chip Set Unidentified Maximum Onboard Memory Unidentified I/O Options Serial ports (4 RS-232) Hard Drives supported None Floppy drives supported None Data Bus 16-bit ISA [Image] CONNECTIONS Function Label 37-pin octopus connector to four CN1 25-pin serial ports BASE I/O ADDRESS SELECTION Setting SW1-4/1 SW1-4/2 SW1-4/3 SW1-4/4 SW1-4/5 SW1-4/6 SW1-4/7 000h On On On On On On On 008h On On On On On On Off 010h On On On On On Off On 018h On On On On On Off Off 020h On On On On Off On On 3D8h Off Off Off Off On Off Off 3E0h Off Off Off Off Off On On 3E8h Off Off Off Off Off On Off 3F0h Off Off Off Off Off Off On 3F8h Off Off Off Off Off Off Off Note: SW4 sets the I/O addresses for port1, SW 3 sets the I/O addresses for port 2, SW2 sets the I/O addresses for port 3, and SW1 sets the I/O addresses for port 4. A total of 128 base address settings are available. The switches are a binary representation of the decimal memory addresses. SW1-4/1 is the Most Significant Bit and switch SW1-4/7 is the Least Significant Bit. The switches have the following decimal values:SW1-4/1=1024, SW1-4/2=512, SW1-4/3=256, SW1-4/4=128, SW1-4/5=64, SW1-4/6=32, SW1-4/7=16. Turn off the switches and add the values of the switches to obtain the correct memory address.
