Section 1: Introduction- Block Diagram (part 2) 10.
Section 1: Introduction- Detailed Description of Functions AUDIO FUNCTIONS Audio Inputs - These are the 3-pin terminal block connectors used for balanced line level audio-signal input. This type of connector is sometimes called“Phoenix”or “Euro” style.
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 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.
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 or switch.
Section 2: Installation- Basics and Mounting UNP ACKING 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.
Section 2: Installation- Mounting and AC Power CONNECTING AC POWER The CM16a uses a detachable IEC standard power cord for connecting to a grounded AC source. To connect power to the CM16a: identify the proper end of the cord, match the orientation of the receptacle on the rear panel and insert firmly into the receptacle.
Section 2: Installation- Connections CONNECTING AUDIO INPUTS The audio inputs are located on the rear panel. The CM16a uses terminal block connectors for the audio inputs.
Section 2: Installation- Connections REAR PANEL- PAGE, RELAY & MONITOR CONNECTIONS 20 CONNECTING THE RL Y OUT The RLY OUT connector provides access to the internal relay’s contacts for remotely controlling an external low voltage device or circuit.
CONNECTING TO THE RS-232 PORT Connection is made with a null-modem serial cable with a DB-9 male plug to the CM16a. The RS-232 port can be used for setting various operational parameters that are CRITICAL to proper operation of the CM16a. The network address settings can be changed through this port.
Section 2: Installation- Rear Panel Detail 22.
23 Section 3: Operation- LED Indicators LED Indicators- When the power is switched “on”, all of the LED’s light briefly and then the PORT LED’s sequence through two patterns. The LED’s then resume normal operation. The LED functions are described below.
NETWORK- The network should be operable and QSControl software should be installed/running on the system controller computer. 24 AMPLIFIER SETUP- The amplifiers connected to the CM16a must have their power switches in the “on” position.
25 Section 3: Operation- Recalling Presets Using RL Y/TRG IN There are three operating modes for recalling presets using the RLY/TRG IN of the CM16a and a set of external contacts (switch, relay or other such device). These modes are set up and accessed using the QSControl software or RS232/Telnet sessions.
26 Section 3: Operation- Bypass Modes and Switch Location BYPASS MODE #2 (SAFE MODE): Use 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 Ethernet/IP settings, stand alone control capabilities, system “health” data, firmware version information and other related data.
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 communica- tion 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 RS-232 features can be accessed via the network. The Microsoft Telnet application is a Windows program. Consult Windows documentation for Telnet information .
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.

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 amplifiers in an Ethernet-TCP/IP based network audio system. Sixteen indepen- dent 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.
