Rail-Split RJ45 User Guide
Overview
Rail-Split RJ45 is a fully bi-directional DMX512 splitter and distribution amplifier, with the added
feature of a ‘data fixer’ for DMX. The latter functionality is used for resolving flickering problems
arising from product incompatibility issues - see ‘Fixer Mode’ on page 6 for more information.

Connections
Input
The DMX512 input is via the RJ45 connector.
Loop-Through
A passive loop-through connection allows
onward connection to other DMX512 devices.
If this feature is not required then the signal
must be terminated. The product contains an
internal termination link. This is enabled by
fitting the shorting plug of the jumper (see
Connection 5 on the previous page) over the
lower pin.
Alternatively, a plug-in RJ45 terminator can
be fitted to Connection 4 (not supplied).
Output
Four DMX512 outputs are provided. Each
output is capable of driving 32 additional
DMX512 devices. It is not necessary to
terminate any outputs that are not connected.
However, a terminator must be connected to
the final DMX512 device.
