NOTE: If communication cannot be established or the control system is locked up,
refer to “Troubleshooting Communications” in the latest version of the Crestron
2-Series Control Systems Reference Guide (Doc. 6256).
NOTE: Passthrough mode enables Toolbox access to any serial controlled device
on the network. This aids in troubleshooting by allowing direct communication
between the PC and a network device (effectively “passing through” the MPC-M5).
For information pertaining to Passthrough mode, refer to “Passthrough Mode” in the
latest version of the Crestron 2-Series Control Systems Reference Guide (Doc. 6256)
