External Audio/Trigger Output Configuration
The external audio/trigger output interface is the SMB connector labeled AUDIO/TRG OUT on
the VXIpc-486 front panel.
You can configure the external audio/trigger output as either an audio output or a TTL trigger
output. The audio/trigger output is connected to the circuit card by a twisted-pair cable. You
can configure the audio/trigger output by connecting the cable to either J13 or J17. Table 2-3
shows the configuration options.

Installed System RAM Configuration
The amount of installed RAM is factory configured per customer order. You can change the
amount of installed RAM on VXIpc-486/1 models by installing dynamic RAM single in-line
memory modules (DRAM SIMMs) in positions A1 and A2, as shown in Table 2-4 and
Figure 2-1.
Warning:
Do not attempt to change the factory RAM configuration of the VXIpc-486/2.
Disassembling the internal brackets in an attempt to expose the DRAM SIMM
sockets will void your warranty.
