RS-232 electrical interface, such as modems, data-entry terminals, and plotters. What’s Included The VERSA COMM+4 is shipped with the following items. If any of these items are missing or damaged, contact the supplier. •... -
Page 6: Card Setup
Card Setup Card Setup The VERSA COMM+4 contains several jumper straps which must be set for proper operation. Address Selection Each port on the VERSA COMM+4 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
Card Setup Port Enable / Disable Each port on the VERSA COMM+4 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: Interrupt Mode Options
IRQs possible. If you are using more than one VERSA COMM+4 or a compatible card in a bus you should only have one port set to " M". The following example shows all four ports sharing a single IRQ. -
Page 9: Figure 6 - Header E5, Sharing Irq's With Another Adapter
Card Setup Set jumper to " S" if you are using more than one VERSA COMM+4 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 resistor will prevent the ports from triggering an interrupt.. -
Page 10: Installation
Installation Installation The VERSA COMM+4 can be installed in any of the PC expansion slots, but to access the “AT” or (E)ISA IRQ’s (10, 11, 12, 15) it must be installed in one of the 16 bit slots. The VERSA COMM+4 contains several jumper straps for each port which must be set for proper operation prior to installing the card into the computer. -
Page 11: Technical Description
Technical Description Technical Description The Sealevel VERSA COMM+4 provides 4 additional serial ports for terminals, modems, printers, etc. The VERSA COMM+4 can be configured as COM1: through COM4:, or as any other I/O address (up to 3FF HEX), providing total compatibility with most communications software and languages. -
Page 12: Connector Pin Assignments
The most common way to do this is connect 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 VERSA COMM+4 Page 8... -

No two adapters can occupy the same I/O address. 3. Make sure the Sealevel Systems adapter is using a unique IRQ. While the Sealevel Systems adapter does allow the sharing of IRQ’s, many other adapters (i.e. SCSI adapters & on-board serial ports) do not. The IRQ is typically selected via an on-board header block. - Page 15 2E8-2EF is typically reserved for COM4: 7. Please refer to your included diskette for any post production manual updates and application specific information. 8. Always use the Sealevel Systems diagnostic software when Troubleshooting a problem. This will eliminate the software issue from the equation.
