Expression 3 - ETC

Installing Full Tracking Backup
Full Tracking Backup (FTB) is a system where two consoles (or one
console and a Lighting Playback Controller), are interconnected using
ETCNet. One functions as the main controller (always the console when
using an LPC) and the other functions as a tracking slave unit. If the main
unit fails, the backup slave takes over immediately. 1
Use the keyswitch at the right end of the console LED display panel to
switch from one controller to the other.
Follow these steps to install a Full Tracking Backup system.
1. Interconnect the consoles (or the console and LPC) by cabling to the
network connectors. Terminate properly.
2. Connect monitors to the slave unit.
3. Set console DIP switches as explained under Setting Expression 3
DIP switches, page 331.
Installing SMPTE
In order to use SMPTE equipment with Expression 3 consoles, the
SMPTE option must have been installed at the factory. Connect the
console to SMPTE equipment using an appropriate SMPTE cable.
Follow these steps to connect SMPTE equipment to the console.
1. Turn console power off.
2. Insert SMPTE cable into the connector on the back of the console
labeled SMPTE.
3. Set a console DIP switch (number 4) to enable SMPTE with reference
to Setting Expression 3 DIP switches, page 331.
