Chapter 1
The Enhanced Monitor of the HP E8402 and E8404 mainframes plugs into
the VXI backplane from the rear of the mainframe. It does not occupy a slot
in the mainframe or tie-up the MODID line. The enhanced monitor is a
message-based device, allowing easy communication over the VXIbus (for
example, through a command module or embedded controller) or a standard
RS-232 interface. The enhanced monitor does require a VXIbus address;
224 is the factory default. Figure 1-4 shows the rear panel of the HP
E8402/E8404 VXI mainframe with the Enhanced Monitor logical address
switches and RS-232 interface.
