Crestron QM-MD16X16 16X16 QuickMedia™ Matrix Switcher

When connecting multiple QM devices, the route between a QM origination point

(transmitter) and a QM endpoint (receiver) cannot have more than two midpoints

(e.g. QM-MD16X16 or other QM switchers). Refer to the following diagram when

configuring a QM network.

NOTE: The aggregate length from transmitter to receiver cannot have a delay skew

or more than 22 ns.

Identity Code

The Net ID of the QM-MD16X16 has been factory set to 32. The Net IDs of multiple

QM-MD16X16 devices in the same system must be unique. Net IDs are changed

from a personal computer (PC) via the Crestron Toolbox™ (refer to “Establishing

Communication” on page 20).

When setting the Net ID, consider the following:

• The Net ID of each unit must match an ID code specified in the SIMPL

Windows program.

• Each network device must have a unique Net ID.

For more details, refer to the Crestron Toolbox help file.

Installation

Ventilation

The QM-MD16X16 should be used in a well-ventilated area. The venting holes

should not be obstructed under any circumstances.

NOTE: To ensure adequate ventilation while surface or rack mounting, do not stack

more than two QM-MD16X16s together.

To prevent overheating, do not operate this product in an area that exceeds the

environmental temperature range listed in the table of specifications. Consider using

forced air ventilation and/or incrementing the spacing between units to reduce

overheating. Consideration must be given if installed in a closed or multi-unit rack

assembly since the operating ambient temperature of the rack environment may be

greater than the room ambient temperature. Contact with thermal insulating

materials should be avoided on all sides of the unit.

Rack Mounting

The QM-MD16X16 can be mounted in a rack or stacked with other equipment. Two

“ears” are provided with the QM-MD16X16 so that the unit can be rack mounted.

These ears must be installed prior to mounting. Complete the following procedure to

attach the ears to the unit. The only tool required is a #2 Phillips screwdriver.
