2 FOUR POR T RS-232 SERIAL INTERF ACE 2.1 Overview The Four Port RS-232 Serial Interface provides your PC system with four RS- 232 asynchronous ports. Connect to any device that uses the RS-232 protocol, such as modems, data-entry terminals, and plotters.
3 CHAPTER 2: Introduction 2.3 Features Listed below are the special features your Serial Interface offers. • Each port is independently addressable. • Eleven interrupt options, including AT interrupts, for simple integration into existing systems.
4 FOUR POR T RS-232 SERIAL INTERF ACE 2.4 T echnical Description The Four Port RS-232 Serial Interface provides four additional serial ports for terminals, modems, printers, etc.
5 CHAPTER 3: Address Selection NOTE Be sure to set the address selections and jumper options before installation. Each serial port on the Four Port RS-232 Serial Interface occupies 8 con- secutive I/O locations. DIP switch SW4 sets the base address for Port 1, SW3 for Port 2, SW2 for Port 3, and SW1 for Port 4.
6 FOUR POR T RS-232 SERIAL INTERF ACE NOTE Be sure to set the address selections and jumper options before installation. The board contains several jumper straps for each port which must be set for proper operation. 4.1 Port Enable/Disable Each port on the Four Port RS-232 can be enabled or disabled with switch position 8 on the DIP switch.
7 CHAPTER 4: Option Selection Any two or more ports can share a common IRQ by placing the jumpers on the same IRQ setting, and setting the appropriate selections at E1. Consult your particular software for IRQ selection. If no interrupt is desired, remove the jumper.
8 FOUR POR T RS-232 SERIAL INTERF ACE 4.2 Interrupt-Mode Options Jumper E5 selects the interrupt mode for each port. Each port must be set in the correct mode to ensure proper installation. “N” indicates the normal, single interrupt per port mode (Figure 4-2).
9 Set jumper to “S” if you are using more than one Four Port RS-232 Serial Interface in a bus or you wish to remove the pull-down resistor completely for hardware compatibility. NOTE Setting the board in this configuration when it is not accompanied by a pull-down resistor will prevent the ports from triggering an interrupt.
