Connectors for EISA, and Optional Graphics The system has a slot for an optional EISA (Extended Industry Standard Architecture) board or an optional CRX , HCRX , VISUALIZE or CRX-48 graphics board. EISA The one-slot EISA I/O port is a superset of ISA (Industry Standard Architecture). It extends the capabilities of that standard while maintaining compatibility with ISA expansion boards. EISA provides 32-bit memory addressing and 32-bit data transfers. The EISA slot allows quick and easy integration in heterogeneous networks as well as simple connections of high-speed, low-cost disks and other peripherals. Some EISA option boards have external connectors for connecting these devices. Consult the documentation that accompanies each device for specific information concerning its use. Optional Graphics If the system has an optional graphics board installed, it will have one of the following graphics connectors: S Color graphics card (CRX-24, CRX-24Z, HCRX-8, HCRX-8Z, HCRX-24, HCRX-24Z , or VISUALIZE graphics) - This device has a D-sub miniature connector which is connected to the monitor by a cable, as shown in Figure Figure 1-4. S Graphics interface card (CRX-48Z graphics) - This device is connected by a cable to an external graphics processor, which in turn is connected to a video monitor, as shown in Figure Figure 1-5. Figure 1-4 shows the location of the CRX or HCRX graphics connector on the system unit's rear panel. Product Information 1-11

Connectors for EISA, and Optional Graphics
The system has a slot for an optional EISA (Extended Industry Standard Architec-
ture) board or an optional
CRX , HCRX , VISUALIZE or CRX–48
graphics board.
EISA
The one–slot EISA I/O port is a superset of ISA (Industry Standard Architecture). It
extends the capabilities of that standard while maintaining compatibility with ISA
expansion boards. EISA provides 32–bit memory addressing and 32–bit data trans-
fers. The EISA slot allows quick and easy integration in heterogeneous networks as
well as simple connections of high–speed, low–cost disks and other peripherals.
Some EISA option boards have external connectors for connecting these devices.
Consult the documentation that accompanies each device for specific information
concerning its use.
Optional Graphics
If the system has an optional
graphics board installed, it will have one of the follow-
ing graphics connectors:
S
Color graphics card (CRX–24, CRX–24Z, HCRX–8, HCRX–8Z, HCRX–24,
HCRX–24Z , or VISUALIZE graphics) — This device has a D–sub miniature
connector which is connected to the monitor by a cable, as shown in Figure
Figure 1–4.
S
Graphics interface card (CRX–48Z graphics) — This device is connected by a
cable to an external graphics processor, which in turn is connected to a video
monitor, as shown in Figure Figure 1–5.
Figure 1–4 shows the location of the CRX or HCRX graphics connector on the sys-
tem unit’s rear panel.
