¨ WARNING ¨ While QSC has endeavored to develop and produce the most depend- able and robust ‘network’ audio product for your use, due to the myriad of network situations and equipment that may be encountered in its implementation, QSC cannot be held responsible for network conflicts and associated consequences that may result. For this reason, QSC strongly recommends that the network used for implementa- tion of QSControl products be completely separate from all other networks, data or other

Important Safety Information! Please review the following important safety information before operating the CM16a. Explanation of Graphical Symbols The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to humans. The exclamation point within an equilateral triangle is intended to alert the u

Section 1: Introduction- List of Functions & Features FUNCTIONAL LISTING, BLOCK DIAGRAM & DETAILED DESCRIPTIONS The CM16a performs remote control and monitoring of amplifiers. Below is a listing of the functions available for the supported QSC amplifiers. The following two pages (Block Diagram part 1 & 2) illustrate the main functions of the CM16a. Following the diagram is a section giving detailed explanations on each functional block that will aid in the use of the CM16a. Note that not all fe

Section 1: Introduction- Network Description QSC CM16a Amplifier Network Monitors are designed to operate on standard 10BASE-T Ethernet. Each CM16a operates as a respective node on its network; each unit contains a programmable IP address in nonvolatile memory. To minimize network conflicts, each IP address should be unique. When shipped from the factory, the CM16a’s factory-programmed IP address is printed on a label affixed to the front panel of the unit. Record the unit’s IP address and seri

Section 1: Introduction- Sample Network Topologies The simplest network configuration is a single system controller computer and a CM16a con- nected by a single Ethernet crossover cable. A standard Ethernet cable would NOT work. The crossover-type cable must be used when con- necting the CM16a directly to the system con- troller computer. This type of cable switches (or crosses over) the transmit and receive sig- nals from one end to the other enabling con- nection without any intermediate devi

Section 1: Introduction- Sample Network Topologies Some networks have multiple system con- troller computers. This configuration is es- sentially the same as the second example with the addition of the second computer attached to the hub or switch. To create the more complex distributed star topologies needed for larger systems, use additional hubs or switches. Some have spe- cial uplink ports for connecting to other hubs or switches via a standard Ethernet cable. If the hubs or switches do not

Section 2: Installation- Basics and Mounting UNPACKING There are no special unpacking precautions for the CM16a. Keep the original packing material for reuse in the rare event that service be required on the CM16a. If service is required and the original packing material is not available, adequately protect for shipment (strong box of appropriate size, sufficient packing material to prevent impact damage or load shifting).

Section 2: Installation- Mounting and AC Power MOUNTING THE CM16a (continued): The illustration below, left, shows the basic mounting technique. Support the CM16a from underneath while positioning the mounting holes in the desired location in the rack. Secure with standard rack hardware. The CM16a uses fan-drawn air for cooling. The air intake is on the left side of the chassis and the exhaust vents are on the front panel. Be certain not to obstruct these openings! Allow ample “open space” arou

Please refer to the previous page for connector pinout. CONNECTING THE RLY/TRG IN The RLY/TRG IN connector is a two-pin terminal block connec- tor. When using this input for a switch-closure (or opening) event, the two terminals should be connected to the switch contacts directly. This type of event detection can be used
