Page 3: Introduction
The ISO-COMM isolated boards provide up to 500 volts DC of isolation. The ISO-COMM provides two or four DOS and Windows compatible serial ports, and also offers extended ‘AT’ interrupts. Each port is independently addressable as COM1: through COM4:, or any other I/O address up to 3FF Hex. -
Page 4: Before You Get Started
Before You Get Started What’s Included The ISO-COMM is shipped with the following items. If any of these items are missing or damaged, contact the supplier. ISO-COMM Serial I/O Adapter • • Cable providing 2 DB-9 connectors. Advisory Conventions Warning The highest level of importance used to stress a condition where damage could result to the product, or the user could suffer serious injury. - Page 5 Before We Get Started, Continued Factory Default Settings The ISO-COMM factory default settings are as follows: Port # Base Address Port 1 Port 2 Port 3 Port 4 For your reference, record installed ISO-COMM settings below: Port # Base Address...

Page 6: Card Setup
The ISO-COMM contains several jumper straps which must be set for proper operation. Address Selection Each port on the ISO-COMM 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 ports. - Page 7 Port Enable / Disable Each port on the ISO-COMM can be enabled or disabled with switch position 8 on the DIP-switch. The port is enabled with the switch ‘On’ or ‘Closed’ and disabled when ‘Off’ or ‘Open’. If any port is disabled, be sure to disable the interrupt request for that port by removing the IRQ jumper.
- Page 8 IRQ. Figure 5 - Header E5, Shared IRQ Mode Set jumper to ‘S’ if you are using more than one ISO-COMM in a bus or wish to completely remove the pull- down resistor for hardware compatibility.

- Page 10 Card Setup, Continued The above example shows the correlation between jumper block E5 and the interrupt jumpers (E1-E4). This example shows the ISO-COMM shipping configuration with COM1: & COM3: sharing interrupt 4 and COM2: & COM4: sharing interrupt 3. Headers E8 and E9 RS-485 is backwardly compatible with RS-422, however it is optimized for party line or multi-drop applications.
- Page 11 Combined RS-232 and RS-422 On the four port ISO-COMM boards two ports of RS-232 and two ports of RS422 is possible, but it is complicated to configure. The configuration requires that you selectively bend (or float) pins on the DIP- resistor pack out of the socket.

Page 12: Installation
Hardware Installation The ISO-COMM can be installed in any of the PC expansion slots, but to access the ‘AT’ or (E)ISA IRQs (10, 11, 12, 15) the adapter must be installed in one of the 16 bit slots. The ISO-COMM contains several jumper straps for each port which must be set for proper operation prior to installing the card into the computer. -
Page 13: Technical Description
Technical Description The Sealevel Systems ISO-COMM provides the PC with two or four additional ground isolated RS- 422/485/232 or two or four non-isolated RS-422/485 serial ports for terminals, modems, printers, etc. Isolation is important in installations where the equipment being connected to the PC is either far from the PC, or on a different power transformer circuit. - Page 14 RTS to CTS and RI. Also, connect DCD to DTR and DSR. Terminating these pins, if not used, will help insure you get the best performance from your adapter. © Sealevel Systems, Inc. 3415, 3416, 3417, 3418, 3419 Manual | SL9149 11/2021...

No two adapters can occupy the same I/O address. 3. Make sure the Sealevel Systems adapter is using a unique IRQ The IRQ is typically selected via an on-board header block. Refer to the section on Card Setup for help in choosing an I/O address and IRQ. -

0 (space) and -12 volts (-3 to -10 volts) denotes a binary 1 (mark). The RS-232 and the EIA/TIA-574 specification defines two type of interface circuits, Data Terminal Equipment (DTE) and Data Circuit-Terminating Equipment (DCE). The Sealevel Systems adapter is a DTE interface. RS-422 The RS-422 specification defines the electrical characteristics of balanced voltage digital interface circuits. -
