40 QUADRAVISTA INSTALLATION AND OPERATIONS MANUAL
Connect the multiple unit system as shown below using a special “Y” serial cable.
When starting a chain of devices, always start by first switching on the device at the end of the
chain. When the device has completed its startup phase and sent its DCP messages, switch on
the next device in the chain. Finally, switch on the first device in the chain, which synchronizes
the settings of all other devices in the chain with its own settings as it starts up. The synchronized
chain can have any length.
Do not connect the last unit to the first to create a loop.
