Data Repeaters are simple 1:2 distribution amplifiers for RS485 data. They have both XLR3 and XLR4 inputs for data and power on our standard arrangement.
The incoming data is cleaned up and resent via two independent data amplifier/line drivers. They are required for very long cable runs or to enable star connection of remote devices where daisy chaining cannot be done.
They will accept any form of RS485 data up to 115k baud.
