DMXManager User Guide

Operational Philosophy

DMXManager combines, merges and converts two
separate data sources into a single output.
Alternatively, it can be used as an automatic soft
switch between two data sources.

Features

• Combines two inputs on a highest takes

precedence basis

• Automatically switches from one input to

another upon loss of signal

• High performance processor

• Output address selection

• “Status Quo” feature maintains last output level

when input signal stops

• Input/output diagnostic functions

• Direct pass-thru connectors

• Sturdy all metal construction

• Optional 19” rack mount kit

Indicators

Three LEDs are used to indicate, from left to right,
power supply / processor run status, data A
receive detect, and data B receive detect. In test
mode the receive detect LEDs will flash if the input
signal is not as selected by the I/O mode switches
or if the signal is unrecognizable.

POWER:

DATA A:

DATA B:

Glowing solidly indicates power
supply and processor OK; off
indicates no power, and flashing
indicates defective processor or
control logic.

Glowing solidly indicates data signal
A received; off indicates no input
signal present.

Glowing solidly indicates data signal
B received; off indicates no input

Address Selection

Three rotary switches select the offset start
address for the unit in most configurations. For
dual AMX output, the address switches select the
starting dimmer number for the second AMX output
line. In merge mode, the switches set the starting
address for the second input data line. In test
mode, the switches set dimmers to full one at a
time. From left to right the switches are set as
hundreds, tens, and ones.

Setup Instructions

The Gray Interfaces Protocol Manager is designed
to permit easy, trouble free conversion between
standard USITT DMX512 and AMX192 lighting
control signals. The unit's main feature is its ability to
manage two separate lines of input data.

A few simple steps are required to prepare your
interface unit for operation. First, assemble your
mating cables and ensure that they conform to the
connector pinouts as shown on page 3. Plug the
cable or cables from your lighting control console
into the input connector on the rear panel of the
protocol manager. The output connector of the
converter box goes to your dimmer rack or other
devices, such as color scrollers.

Next set the rotary address select switches
according to the instructions on page 4. In most
applications this will be the factory default 000 or

001.
Set the first two positions of the 8-position DIP

switch according to the operating mode required. In
BACKUP mode, one or two input data lines may be
active, but the unit will read only the first. If that line
should become disabled, the Protocol Manager
automatically switches over to read the second line.

In PILE-ON mode, one or two input data lines may
be active, and the unit's output will be determined by

MERGE mode provides a means of connecting
two input signals "end to end" to create one
output signal consisting of the total number of
channels on both inputs. The most common
application of this is for two AMX192 inputs and
one DMX512 output. Another common use for
merge mode is to create an address offset
between input and output DMX data. Simply
connect the input line to Input #2 and set the
rotary address switches to the desired offset.

TEST mode is a useful diagnostic tool which
enables the user to verify Protocol Manager
input/output connections and signal integrity. The
unit will analyze the selected input protocol and
generate the selected output protocol to assist in
pinpointing network problems. More details on
test mode can be found on page 4.

Next determine the I/O (input/output) mode, eg.
DMX-in / AMX-out, and set DIP switches 3 and 4
accordingly. If two AMX outputs are required, turn
on switch 7. Note that not all I/O applications are
available on any one model of Protocol Manager.
The options available on your particular model
are listed on the label on the top of your unit.

Finally, set the desired status quo timeout with
DIP switch 5. Status quo maintains the last valid
channel levels in the event of loss of input data.
