Can Transceivers and Split Boxes be connected in parallel?

Post by Closetalk Support »

Yes! As of July 2014, the Split Box supports being connected in parallel with Transceiver Units directly connected to the Central Unit. This reduces the number of required Split Boxes and lowers the total system cost.

This only applies to new Split Boxes sold beginning July 2014 and later! Older Split Boxes are still subject to the original installation requirements. When ordering a Split Box, be sure to specify whether it will be used for an old or new installation.

Updated installation requirements for new Split Box model
Please note that the new Split Box model "adds" 5 meters of cable length, i.e. the total cable segment length for a Transceiver Unit directly connected to the Central Unit and in parallel with a Split Box must be 5 meters longer compared to the total cable length for the Split Box zone, this is to maintain phase accuracy and system stability.

A Split Box is connected to the Central Unit using a 20 meter Cable. The Transceivers connected to the Split Box uses 5 meter cables, making the total cable length for the Split Box zone 20 + 5 = 25 meters.

Therefore, every other Transceiver connected directly to the Central Unit, in parallel with the Split Box zone, must have a cable length of 25 + 5 = 30 meters where the extra 5 meters compensates for the signal delay in the Split Box.
