* SW8 is OFF for non-interlaced monitors, and ON for

monitors.
** Factory default is non-interlaced VGA (color).
* The BC 4000 video outputs are analog (VGA) and will only function with analog compatible monitors.
The BC 4000 board can be configured to perform a hardware reset when the Data Carrier Detect (DCD) or Data Set Ready (DSR) signal changes from true to false. Jumpers on jumper block JP3 determine which signal from which COM port will reset the board. Figure 2-2 shows each configuration for JP3.
* A jumper across pins 1 and 2 resets the hardware when the DSR signal drops on COM1.
* A jumper across pins 3 and 4 resets the hardware when the DSR signal drops on COM2.
* A jumper across pins 5 and 6 resets the hardware when the DCD signal drops on COM1.
* A jumper across pins 7 and 8 resets the hardware when the DCD signal drops on COM2.
To disable reset on loss of DCD or DSR, remove all of the jumpers.
This automatic reset option may only be configured on one COM port at a time. On that COM port, reset on loss of DCD, DSR, or both signals may be selected. Therefore, do not put jumpers simultaneously on pins 1, 2, 3, and 4. Do not put jumpers simultaneously on pins 5, 6, 7, and 8.

The IDE disk controller can be disabled if necessary in the CMOS setup program. This would be necessary if, for example, a SCSI adapter was installed and the SCSI adapter's hard disk was to be used as a boot device. To completely disable the IDE hardware, shunt JP4 position 3-4 must be ON.
* To recover IRQ 14, all IDE drives must be removed from the 40-pin header cable.
Figure 2-3, Jumper Block JP4 - IDE Configurations
Two serial and one parallel port are available on the BC 4000. COM1 uses IRQ 4, COM2 uses IRQ 3, and LPT1 uses IRQ 7. If these I/O ports are not needed, their interrupts can be recovered for use by other hardware devices. To disable the ports and recover the interrupts, place a shunt on JP4 positions 1 and 2. Factory default is to enable the ports.
Figure 2-4, Jumper Block JP4 - COMM & LPT Configurations
A mouse may optionally be connected to the BC 4000. To enable the mouse interrupt (IRQ 12), place a shunt on jumper block JP5. Factory default is to disable the mouse interrupt.
The BC 4000 is designed to interface with a power supply and cause an interrupt in the event of an A.C. failure. The interrupt may be configured to occur on IRQ 10 or IRQ 15 using JP1. Placing a shunt on pins 1-2 selects IRQ 15. Placing a shunt on pins 2-3 selects IRQ 10. Factory default selects no A.C. Fail interrupt, leaving both IRQ 10 and IRQ 15 available for other hardware devices.

Once the hardware options are configured, the BC 4000 should be installed in the bus master slot as follows:
1. Power down the system in which the BC 4000 will be installed.
2. Gain access to the passive backplane. Typically this requires removing the cover from the computer.
3. Seat the BC 4000 into the bus master slot in the backplane (refer to Figure 2-4) The bus master slot is identified by the additional EISA style connector in line with the standard EISA connector.
4. Secure the BC 4000 with a screw.
5. Connect the appropriate cables to the BC 4000 (refer to Figure 1-1).
6. Reassemble the system as necessary (e.g. replace the computer's cover).
7. Apply power to the system.
To verify that the system is functioning properly, connect a monitor to J11 and a keyboard to J10.
After the standard CMOS setup has been configured and DOS is up and running; the EISA configuration utility (CFG) must be executed to set up EISA CMOS memory.
Figure 2-6, Slot Identification.
A parallel port may optionally be added to function as LPT1 of the BC 4000. This requires a Cubix LPT1 printed circuit board (PCB) adapter and bracket, a panel opening where the DB-25 connector can be installed, and a 20-conductor ribbon cable.
INSTALLATION
Warning: Turn off the power to the system before beginning this procedure.
1. Install the Cubix LPT1 adapter in a panel opening on the system. Typically, an opening provided for an empty board space is dedicated to the LPT1 connector. In this case, install the bracket next to the BC 4000 board and tighten the screw firmly.
Alternately, if the LPT1 connector is being installed into a Cubix auxiliary junction panel, the bracket provided with the LPT1 adapter should be removed. Unscrew the connector from the bracket and install the adapter into the desired panel opening.
2. Connect one end of the 20conductor ribbon cable to the LPT1 header (J7) on the BC 4000 board. The pin-one side of the ribbon cable is marked with a colored (blue or red) stripe. Pin one on the BC 4000 header is labeled with a triangular arrowhead (Ú). Align the pin-one side of the ribbon cable with pin one on the header.
3. Connect the other end of the ribbon cable to the LPT1 adapter. Pin one on the adapter is labeled with a triangular arrowhead. Align the pin-one side of the ribbon cable with pin one on the adapter.
4. Plug the peripheral device's cable into the DB25 connector.
Figure 2-7, LPT1 Adapter Connected to BC 4000.
A second serial port may optionally be added to function as COM2 of the BC 4000. A PS/2 mouse input port may also be added. This requires a Cubix printed circuit board (PCB) adapter and bracket, and a single panel opening where the DB-9 and Mini-DIN 6 can be installed. Both the COM2 and the mouse interfaces are provided on the same PCB adapter. To connect COM2 requires a 10-conductor ribbon cable; the mouse port requires a 5-conductor cable.
INSTALLATION
Warning: Turn off the power to the system before beginning this procedure.
1. Install the Cubix PCB adapter in a panel opening on the system. Typically, an opening provided for an empty board space is dedicated to the COM2 and mouse connectors. In this case, install the bracket next to the BC 4000 board requiring the COM2/mouse port, and tighten the screw firmly.
Alternately, if the COM2 and mouse connectors are being installed into a Cubix auxiliary junction panel, the bracket provided with the COM2/mouse adapter should be removed. Unscrew the connectors from the bracket and install the adapter into the desired opening.
2. Connect one end of the 10conductor ribbon cable to the COM2 header (J8) on the BC 4000 board. The pin-one side of the ribbon cable is marked with a colored (blue or red) stripe. Pin one on the BC 4000 header is labeled with a triangular arrowhead (Ú). Align the pin-one side of the ribbon cable with pin one on the header.
3. Connect the opposite end of the 10-conductor cable to the 10-pin header on the Cubix adapter board. Pin one on the adapter is indicated in Figure 2-6. Align the pin-one side of the ribbon cable with pin one of the 10-pin header on the adapter board.
4. Connect one end of the 5-conductor cable to the PS/2 mouse header (J4) on the BC 4000 board. Pin numbers one through five are indicated on the cable connector. Pin one of the BC 4000 header is indicated in Figure 2-6 Align pin one of the cable connector with pin one on the header.
5. Connect the opposite end of the 5-conductor cable to the 5-pin header on the Cubix adapter board. On the adapter board, pin one of the 5-pin header is the closest pin to the edge of the board. Align pin one of the cable connector with pin one on the header.
6. If COM2 is to be used, plug the peripheral device's cable into the DB9 connector.
7. If a mouse if to be used, plug the mouse connector into the Mini-DIN 6.
F Use JP5 to enable the mouse interrupt (IRQ 12). Also check advanced CMOS setup to make sure mouse support is enabled in the BIOS.
