Every module within a VXIbus system must have a unique logical address; no
two modules can have the same address. On the VX4792 Arbitrary Waveform
Generator, you select the logical address value using a switch located beneath the
right cover. The waveform generator has two user-selectable address modes:
Dynamic Auto Configuration and static.
With Dynamic Auto Configuration address mode (hexadecimal FF
255 decimal), the system resource manager automatically sets the address to the
next available value within your system. For example, if you have devices set to
addresses 01 and 02 already in your system, the resource manager will automati-
cally assign address 03 to the waveform generator at power-on.
Static address mode sets the address to a fixed value between 0 and 255. This
mode ensures that the waveform generator address remains fixed for compatibili-
ty with systems that require a specific address value.
Remember that each device within your system must have a unique address to
avoid communication problems.
The logical address switch (Figure 1–1) is located beneath the right cover. The
8-section switch has the following characteristics:
H An OPEN switch selects binary 1
H A CLOSED switch selects binary 0
H Switch 1 sets least-significant digit, switch 8 sets most-significant digit
Use the following procedure to set the logical address:
CAUTION. Many components within this instrument are extremely susceptible to
static-discharge damage. Remove the instrument covers only in a static-free
environment. Observe standard handling precautions for static-sensitive devices.
Always wear a grounded wrist strap when handling the waveform generator.
1. Use a screwdriver with a size T-10 TorxR tip to remove six screws
(Figure 1–1), then lift off the right cover.
2. Set the switch address mode and binary value as desired:
H Set switches 1 through 8 to OPEN for Dynamic Auto Configuration
H Set switches for a static address between 0 and 255 (decimal)
3. Slide the right cover in place, then install the six screws.
