Chapter 1 Hardware Configuration 1.1 General Description The Star Gate Technologies, Inc., Optum family of multiport serial I/O controllers consists of the Optum 4 and the Optum 8. The Optum 4 permits up to four (the Optum 8 permits up to eight) serial devices to be interfaced with an ISA (Industry Standard Architecture) or EISA (Extended Industry Standard Architecture) bus personal computer. 1.2 Hardware Configuration You may need to make some adjustments to the DIP switches on the main board before installing the board in your host PC. CAUTIONS The Optum serial I/O controller contains several components that can be permanently damaged if the controller is handled improperly. To avoid accidental damage, follow these recommendations: ù Before handling the main board, touch a grounded object to discharge any static electricity that has built up on your body. ù Never insert or remove the main board while power is applied to the computer. Once the computer power switch is shut off, wait at least 10 seconds for the power supply to discharge before inserting or removing the main board. ù Hold the main board only by its edges. ù When using the direct connect version of the product (without an external connection panel), never connect or disconnect either end of the multi-legged cable from the main board to a peripheral device while power is applied to the computer and the peripheral device. When using the external panel option, never connect or disconnect either end of the cable from the main board to the external panel while power is applied to the computer and the peripheral devices. The hardware configuration is determined by one 8-position DIP switch (SW3) and two 4-position DIP switches (SW1 and SW2). Refer to Figure 1.1 which shows the locations of these switches.

Then choose switch selections to match. If you need more information on interrupt operation or I/O channel addressing, refer to the system's technical reference manual. 1.2.1 Interrupt Selection The Optum I/O controller supports two interrupt modes which are selected by position 3 of SW2. Mode 1, which is selected when position 3 of SW2 is set to OFF, directs all ports to interrupt on the IRQ determined by one of the eight positions on SW3 or position 1 or 2 of SW2. See Table 1.1. TABLE 1.1_Interrupt Selection for all Ports with Position 3 of SW2 set to OFF SW3 SW3 SW3 SW3 SW3 SW3 SW3 SW3 SW2 SW2 SW2 Interupt POS POS POS POS POS POS POS POS POS POS POS Selected 1 2 3 4 5 6 7 8 1 2 3 IRQ 2 OFF OFF OFF OFF OFF OFF OFF OFF OFF ON OFF IRQ 3 OFF OFF OFF OFF OFF OFF OFF OFF ON OFF OFF IRQ 4* OFF OFF OFF OFF OFF OFF OFF ON OFF OFF OFF IRQ 5 OFF OFF OFF OFF OFF OFF ON OFF OFF OFF OFF IRQ 6 OFF OFF OFF OFF OFF ON OFF OFF OFF OFF OFF IRQ 7 OFF OFF OFF OFF ON OFF OFF OFF OFF OFF OFF IRQ 10 OFF OFF OFF ON OFF OFF OFF OFF OFF OFF OFF IRQ 11 OFF OFF ON OFF OFF OFF OFF OFF OFF OFF OFF IRQ 12 OFF ON OFF OFF OFF OFF OFF OFF OFF OFF OFF IRQ 15 ON OFF OFF OFF OFF OFF OFF OFF OFF OFF OFF * default setting Mode 2, which is selected when position 3 of SW2 is set to ON, is the DOS compatibility mode. In this mode, port 1 interrupts on IRQ4, port 2 interrupts on IRQ3, and the remaining ports interrupt on an IRQ determined by one of the positions 1-7 on SW3 or position 2 of SW2. See Table 1.2. TABLE 1.2_Interrupt Selection for all Ports (except Ports 1 and 2) with Position 3 of SW2 set to ON SW3 SW3 SW3 SW3 SW3 SW3 SW3 SW3 SW2 SW2 SW2 Interupt POS POS POS POS POS POS POS POS POS POS POS Selected 1 2 3 4 5 6 7 8 1 2 3 IRQ 2 OFF OFF OFF OFF OFF OFF OFF ON OFF ON ON IRQ 5 OFF OFF OFF OFF OFF OFF ON OFF OFF OFF ON IRQ 6 OFF OFF OFF OFF OFF ON OFF OFF OFF OFF ON IRQ 7 OFF OFF OFF OFF ON OFF OFF OFF OFF OFF ON IRQ 10 OFF OFF OFF ON OFF OFF OFF OFF OFF OFF ON IRQ 11 OFF OFF ON OFF OFF OFF OFF OFF OFF OFF ON IRQ 12 OFF ON OFF OFF OFF OFF OFF OFF OFF OFF ON IRQ 15 ON OFF OFF OFF OFF OFF OFF OFF OFF OFF ON CAUTION To prevent possible damage to an Optum controller which is set for mode 2 interrupt operation, make sure position 8 of SW3 and position 1 of SW2 are set to OFF before you install and operate the controller. 1.2.2 I/O Address Selection There are eight sets of I/O address maps for the serial ports. Table 1.3 lists the interrupt status register address and the port I/O addresses for each set.

(Position 1 of DIP switch SW1 is not used.) See Table 1.4.

Configure the first Optum controller to I/O address map Set 3, and configure the second Optum controller (if used) to I/O address map Set 4. ù For a SCO UNIX or SCO XENIX system with a built-in COM1 port, only one Optum controller may be used, and its I/O address map must be configured to Set 4. ù For a SCO UNIX or SCO XENIX system with a built-in COM2 port, only one Optum controller may be used, and its I/O address map must be configured to Set 3. ù For a SCO UNIX or SCO XENIX system with a built-in COM1 port and a built-in COM2 port, you can not use an Optum controller. In this case, either disable one or both of the built-in COM ports or please use an ACL family or an Avanstar family controller. ù You can use any I/O address map set listed in Table 1.3 for an Optum controller in a DOS, PC-MOS, or QNX system. A second Optum controller installed in the system must use a different I/O address map set. (You do not need Programmable Logic Devices to set I/O addresses for Optum controllers in computers using these or any other operating system.) The bit assignment for each interrupt status register is shown in Table 1.5. TABLE 1.5_Interrupt Status Register Bit Assignment Bit 7 6 5 4 3 2 1 0 PORT 8 PORT 7 PORT6 PORT 5 PORT 4 PORT 3 PORT 2 PORT 1 The bit corresponding to the port for which an interrupt request is pending is set to 1. The bit corresponding to the port for which no interrupt request is pending is cleared to 0.1.2.3 Selecting I/O Cycle Duration Switch SW2 position 4, which determines the I/O cycle duration, is enabled for a 4-clock I/O cycle by default. If your computer exhibits problems running with a 4-clock I/O cycle, set position 4 of switch SW2 to OFF to enable the computer to operate at a slower 6-clock I/O cycle. 2.1 Controller Installation When the Optum controller is properly configured, it may be installed in the PC. Refer to your PC manual for instructions on removing the cover to the PC so that the main board can be inserted into an expansion slot. When the controller is properly installed, replace the cover to your PC according to the instructions in your PC manual. Then go to section 2.2 for instructions on connecting peripheral devices. 2.2 Connecting Peripheral Devices If you selected the direct connect option, connect the single-leg end of the cable to the main board and connect the multi-leg ends to your peripheral devices. If you selected the external panel option, connect the main board to the external panel with the supplied cable and connect your peripheral devices to the sockets on the external panel. The Electronic Industry Association (EIA) 232 interface pin assignments are identified in Table 2.1.
