EXPLANATION OF GRAPHICAL SYMBOLS The lightning flash with arrowhead sym- bol, within an equilateral triangle, is in- tended 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.
Section 1: Introduction- Overview The QSC CM16a Amplifier Network Monitor provides powerful amplifier management and zone paging capability in a QSControl networked audio system using Ethernet networking technology to communicate with the host computer/system controller.
Section 1: Introduction- Physical Characteristics & Layout PHYSICAL CHARACTERISTICS Each CM16a is one rack space in height (1RU) and has an internal AC power supply. Its chassis depth is 37.7 cm (14.84 in.). The width of the chassis is 44.0 cm (17.
Section 1: Introduction- Physical Layout Diagram 7.
Section 1: Introduction- List of Functions & Features FUNCTIONAL LISTING, BLOCK DIAGRAM & DET AILED DESCRIPTIONS The CM16a performs control and monitoring of amplifiers remotely. Below is a listing of the functions that are available for the supported QSC amplifiers.
Section 1: Introduction- Block Diagram (part 1) The following diagrams illustrate the basic functional blocks of the CM16a. Keep in mind that the first diagram is “duplicated” for each of the eight ports.
Section 1: Introduction- Block Diagram (part 2) 10.
Section 1: Introduction- Detailed Description of Functions AUDIO FUNCTIONS Audio Inputs - These are the “Phoenix”-type 3 pin connec- tors used for balanced line level audio-signal input. Input Sensitivity- Sets the sensitivity of the Audio Inputs to either 1 Volt or 3 Volts (r.
Section 1: Introduction- Detailed Description of Functions AMPLIFIER MONITORING FUNCTIONS Amplifier Model Detect- Identifies what model of QSC amplifier is connected to the CM16a’s DataPort. Amplifier Gain Detect - Reports the setting of the amplifier’s gain setting (in dB) for each channel.
Section 1: Introduction- Detailed Description of Functions RS-232 PORT FUNCTIONS RS-232 Port- The RS-232 (serial) port is used to communicate with the CM16a for Ethernet address setup purposes and other diagnostic purposes.
Section 1: Introduction- Network Description 14 QSC CM16a Amplifier Network Monitors are designed to operate on standard 10 BASE -T Ethernet. Each CM16a operates as a respective node on its network; each unit contains a programmable IP address in nonvolatile memory and will therefore present n o conflict with any other node on the same network.
Section 1: Introduction- Sample Network T opologies 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.
Section 1: Introduction- Sample Network T opologies 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. To create the more complex distributed star topologies needed for larger systems, use additional hubs.
Section 2: Installation- Basics and Mounting UNP ACKING There are no special unpacking precautions for the CM16a. However, it is recommended that you keep the original packing material for reuse in the rare event that service be required on the CM16a.
Section 2: Installation- Mounting and AC Power MOUNTING THE CM16a (continued): The illustration below shows the basic mounting technique. 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.
Section 2: Installation- Connections CONNECTING AUDIO INPUTS The audio inputs are located on the rear panel. The CM16a uses “Phoenix”-type (Euro-style) terminal block connectors for the audio inputs. These connectors allow the installer to pre-wire the input termina- tions before the CM16a is installed in the rack.
Section 2: Installation- Connections REAR PANEL- PAGE, RELAY & MONITOR CONNECTIONS CONNECTING THE MONITOR CHAIN IN/ OUT The MONITOR CHAIN connector is a five pin version of the “Phoenix”-type connector. The center pin is the shield connection for both the input and output of the monitor chain.
CONNECTION TO 10BASE-T (network connection) Connection to the Ethernet network is made using the RJ-45 type connector labeled 10BASE-T on the rear panel.
Section 2: Installation- Rear Panel Detail 22.
Section 2: Installation- Hookup Example 23.
Section 3: Operation- General AMPLIFIER SETUP- The amplifiers connected to the CM16a should have their power switches in the ON position and their gain controls set as required by the user (see Initial Testing note below).
Section 3: Operation- LED Behavior & Bypass Switch Usage BYP ASS SWITCH USE There are two distinctly different BYPASS modes. The first mode is the “Oops, I forgot the computer” or system troubleshooting type of BYPASS .
26 Section 3: Operation- Bypass Switch Usage (continued) The second mode ( “ safe ” mode)is used if the CM16a becomes inoperable (or behaves in completely unexpected ways) after uploading a new application file (TFTP file transfer).
The RS-232 connector on the rear panel is used as a serial port input/output (I/O). This I/O port is used for accessing controls for the IP address settings, system “health” data, firmware version information and other related data. Typically, this interface is not used by the majority of users.
28 Section 3: Operation- Serial Port I/O Interface 5) The Properties window for the selected COM port should now be active. It should be similar in appearance as the example to the right. For the Port Settings, use the following information so that commu- nication between the CM16a and the computer is in the same “language”.
29 Section 3: Operation- Serial Port I/O Interface 6) The Hyper Terminal main window will appear next, but blank. Type the letter “h” (for help) and then the “Enter” key. This will prompt the CM16a to post its menu text. The “h” key is the Help prompt for the CM16a.
30 Section 3: Operation- T elnet Access The features outlined for the RS-232 port can also be accessed via the Ethernet network connection. This feature can save a trip out to the remote CM16a with a laptop computer as long as the network and software are fully operable.
31 FUSE REPLACEMENT If the CM16a does not power-up when the POWER switch is in the “on” position ( POWER indicator LED does not illuminate) check the source of AC power and the connection of the power cord at the outlet and IEC receptacle ends.
32 Section 4: Specifications- Dimensions Below are shown the dimensions s of interest for the CM16a. These dimensions are helpful for locating the rear-supports for the CM16a when used in portable or touring installations.

36 SECTION 5: ARCHITECT ’ S AND ENGINEER ’ S SPECIFICA TIONS The Amplifier Network Monitor shall provide input, output, and status control for DataPort equipped QSC power ampli- fiers in an Ethernet-TCP/IP based network audio system. Sixteen independent channels shall be provided, grouped in pairs.
37 Section 6: Appendix- Ethernet Cable Pinouts A crossover cable has the RX and TX wire pairs switched around at one end. There are only two likely situations that would require a crossover cable: to connect a single system controller computer directly to a single CM16a device; and to cascade hubs that don’t have uplink ports.
