Page 5: Card Setup
Card Setup Card Setup The COMM+232/EX contains several jumper straps which must be set for proper operation. Address Selection Each port on the COMM+232/EX occupies eight consecutive I/O locations. A DIP-switch is used to set the base address for these locations. -
Page 6: Port Enable / Disable
Card Setup Port Enable / Disable Each port on the COMM+232/EX 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 7: Interrupt Modes
