– Compatibility & Integration
The VX4237 installs directly into VXIbus mainframe chassis. VME daisy-chain signal management via backplane jumper straps is required when empty slots occupy positions to the left of the module. Consult mainframe documentation for configuration details specific to your chassis size and slot arrangement.
