Description

RP1

SP2

1810-0279
1820-3975
3101-3066

Resistor Network, 9- by 4.7kOhm
IC, 74HC541 Octal Line Driver
Switch,DIP,8-Rocker .OSA 30VDC

Each bit in the Device Type Register is normally pulled high (1) by RP1.

The bits can be reconfigured using the DIP switch. The range of device
types for an A24 or A32 device is 0 - 4095. For an A16 device, all 16 bits
are available for specifying the device type for a range of 0- 65535. The
user will need to add the required buffer and resistor network to implement
the full A16 device type range. The default factory setting is FFxxh.

Note

Per the VXIbus Specification (OBSERVATION C.2.6), device types 0-255
are reserved for register-based Slot 0 devices.

Refer to the VXIbus Specification, Section C.2.1.1.2 for detailed
information concerning Device Type Register implementation restrictions.
Table 2-6 shows the Device Type Register bit definitions.
