Advisories
Three types of advisories are used throughout the manual to stress important points or warn of potential
hazards to the user or the system. They are the Note, the Caution, and theWarning. Following is an example
of each type of advisory:
Note: The note is used to present special instruction, or to provide extra information which may
help to simplify the use of the product.
CAUTION!
A Caution is used to alert you to a situation which if ignored may cause injury or
damage equipment.
WARNING!
AWarningisusedtoalertyouofasituationwhichifignoredwillcauseseriousinjury.
Cautions and Warnings are accented with triangular symbols. The exclamation symbol is used in all cautions
and warnings to help alert you to the important instructions. The lightning flash symbol is used on the left
hand side of a caution or a warning if the advisory relates to the presence of voltage which may be of
sufficient magnitude to cause electrical shock.
Use caution when servicing any electrical component. We have tried to identify the areas which may pose
a Caution or Warning condition in this manual; however, ICS Advent does not claim to have covered all
situations which might require the use of a Caution or Warning.
You must refer to the documentation for any component you install into a computer system to ensure proper
precautions and procedures are followed.

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” to the DB-37 connector mounted on the board (see Figure 1-1) and
you are done.

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.
SW 4 sets the I/O address for port 1, SW 3 sets the address for port 2, SW 2 sets the I/O address for
port 3, SW 1 sets the address for port 4, as labeled on the cable.

If you don’t see an address in the table that is compatible with your software, you can determine the
switch setting for a particular address by using the table below. The following table shows the
correlation between the dip switch setting and the address bits used to determine the base address. In
the example below, the address 300 HEX through 307 HEX is selected. 300 HEX = 11 0000 0XXX
in binary representation.

1A9 1OFF
2A8 1OFF
3A7 0ON
4A6 0ON
5A5 0ON
6A4 0ON
7A3 0ON
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”.

Manual Number: 00750-004-14 Page 3-1
Chapter 3: Option Selection
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).
E1-E4: Selects the interrupt for each serial port. If COM1: is selected, this jumper must be on the
IRQ4 setting. If COM2: is selected, this jumper must be on IRQ3.
NOTE:
Most communications software applications default COM3: to IRQ4 and COM4: to IRQ3. This
requires the sharing of interrupts between COM1: and COM3:, and between COM2: and COM4:.
Whilethisisthedefault,itisnotalwaysthepreferredsetting. Checkyourapplication’sconfiguration
instructions to ascertain the most appropriate IRQ selection.
Any two or more ports can share a common IRQ by placing the jumpers on the same IRQ setting
and setting the appropriate selection at E5. Consult your particular software for IRQ selection. If
no interrupt is desired, remove the jumper.
Note - that IRQ 2 on AT class machines is not available for users. IRQ 9 is substituted in place of
IRQ 2. To select IRQ 9 place jumper on the IRQ 2 position.

E5: “N” indicates the (N)ormal, single interrupt per port mode. The “S” indicates the (S)hared
interrupt mode, which allows more than one port to access a single IRQ. The (M) indicates the
inclusion of a 1K OHM pull-down resistor required on one port when sharing interrupts.

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

Manual Number: 00750-004-14 Page 3-3
should only have one port set to "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 factory default for this is COM1 & 3, sharing IRQ4 and
COM2 & 4, sharing IRQ3.

Chapter 4: Technical Description
WINCOMM4 Four Port RS-232 Serial Interface
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.
Features:
• Provides a COM1: turnkey solution
• Four RS-232 ports with full modem control signals
• Individually selectable address and interrupts (IRQS 2-7 and 10, 11, 12, or 15 on the AT connec-
tor)
• Multiple cards or ports can share the same IRQ
• 4 DB-25 male connectors provided using the systems “spider cable”
The WINCOMM4 board utilizes the same 16550 UART chip found in the IBM asynchronous
adaptor. This chip features programmable baud rate, data format and interrupt control. Refer to
the IBM technical reference for details on programming the chip.
Each serial port can be set as COM1:- COM4:, providing total compatibility with most communi-
cations software and languages, or any other I/O address up to 3FF HEX. Some software packages
require the use of the modem handshake signals such as CTS or DCD. Consult the particular
manual for your software to determine these requirements. If none are mentioned, or if you are not
sure, a safe configuration is to tie DTR to DSR and DCD (6-8-20), and tie RTS to CTS (4-5). This
usually satisfies the modem signal requirements for most communications software.
How to remain CE Compliant
In order for machines to remain CE compliant, only CE compliant parts may be used. To keep a
chassis compliant it must contain only compliant cards, and for cards to remain compliant they
must be used in compliant chassis. Any modifications made to the equipment may affect the CE
compliance standards and should not be done unless approved in writing by Industrial Computer
Source.
The Model WINCOMM4 is designed to be CE Compliant when used in an CE compliant chassis.
Maintaining CE Compliance also requires proper cabling and termination techniques. The user is
advised to follow proper cabling techniques from sensor to interface to ensure a complete CE
Compliant system. Industrial Computer Source does not offer engineering services for designing
cabling or termination systems. Although Industrial Computer Source offers accessory cables and
termination panels, it is the user's responsibility to ensure they are installed with proper shielding
to maintain CE Compliance.
