Overview
DMX-Buffer & DMX-Clarify
DMX-Buffer and DMX-Clarify are designed
to allow a DMX line to run further than the
standard limit of 300m, without the need for
expensive DMX splitters. They achieve this by
internally re-buffering the DMX signal.
The difference between the products lies in
the way they handle RDM data.
y Each product provides an extra 300m of
cable run
y Protected (non-isolated) input
y Single buffered output
y DMX-Buffer supports RDM, allowing
remote configuration of the fixtures
y DMX-Clarify filters out RDM (see detailed
operation below)
y Powered from a standard 9V PSU with DC
jack connector; protective metal case
y Data input: standard 5-pin male XLR
connector with internal termination
y Data output: standard 5-pin female XLR
connector
y DMX-Buffer is also available with RJ45
Ethercon input/output connectors
DMX-Clarify detailed operation
DMX-Clarify is designed to solve product compatibility problems. There are numerous products
on the market that will not accept the wide range of legal DMX timings and data. DMX-Clarify
cleans out any unusual or non-standard timing and data before sending to the output. This
includes stripping out all non-zero start codes (including RDM), forcing a 512-channel footprint
and calming any timing jitter.
Accepts and corrects break in range 56 µs – 1000 µs and outputs 250 µs
y
Accepts and corrects MaB in range 5 µs – 1000 µs and outputs 30 µs
y
Accepts and corrects MaB in range 0 µs – 1000 µs and outputs 30 µs
y
Accepts channel count 1 – 512 and outputs 512
y
Accepts refresh period from 23 ms – 1000 ms and outputs 30ms
y
Filters out multiple consecutive breaks
y
Re-times bytes of 1 stop bit to 2 stop bits
y
Filters out all non-zero start code packets
y
Re-times digital signal

DMX-Buffer, DMX-Clarify & DMX-Protect User Guide
DMX-Protect
DMX-Protect is a passive in-line protector
designed to protect a DMX line from damage
due to electrocution. It has two levels of
protection.
The first is a self-healing circuit that protects
against accidental connection to mains and
will recover when the fault is removed.
The second is a 'protection of last resort' that
will sacrifice the product in order to protect
against high energy faults such as lightning
strikes.
y Passive in-line protector
y Bidirectional protection - both I/P & O/P
are protected from fault on other side
y Protects against accidental connection to
mains (recoverable fault)
y Sacrificial protection against lightning
strikes (non-recoverable fault)
y Supports RDM
y Protective metal case
y Data input: standard 5-pin male XLR
connector with internal termination
y Data output: standard 5-pin female XLR
