SETUP INSTRUCTIONS
T
he 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 the highest individual
channel levels on each line.
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 foundon 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 particualr 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.
