The CM6800E allows you to restrict system control by (1) limiting the monitors or cameras a 
keyboard can access, or (2) limiting the cameras that can be viewed on a monitor.

The CM6800E Matrix Switcher provides four formats for displaying alarmed cameras on system 
monitors: Block Build, Chronological Pair, Reverse Chronological Pair, and Salvo Group.

To display on a monitor, an alarm must be assigned to one or more alarm groups. The 
CM6800E-48X8 Matrix Switcher provides eight alarm groups (A through H). The CM6800-32X6 
Matrix Switcher provides six alarm groups (A through F). Refer to Alarm Groups and Alarm Group 
Display Options.

A priority alarm appears on system monitors before a non-priority alarm. Refer to the Priority 
description under Internal and External Alarms.

The binary, 7-bit, 128-character set implemented as the standard in communications. 

Output relays can be used to control external devices based on matrix switcher activities. External 
devices can include VCRs, alarm devices, and triggers for audio circuits.

In video, the greater the speed, the larger amount of information passed. In digital systems, this 
capacity is given in bits per second, or baud rates.

An abbreviation for “binary digit” – the smallest unit of information a computer can use. A bit is 
either a 1 or a 0 (a high or low voltage state).

An abbreviation for “binary term” – bytes are strings of bits, operated upon as a unit. A byte is 
equal to eight bits (256 possibilities) and is large enough to hold one character (like an “A” or the 
number “1”.)

Some cameras contain an auxiliary output relay, which can be used to operate a device connected to 
the relay.

This is Pelco’s “up the coax” control technology. Control signals are sent back up the coaxial cable 
that the video signal travels down on.

This is a communication port input on the rear panel of the matrix switcher.

A matrix switcher that can select any video input onto any video output at any time.

This is a way of providing multiple connections in a series, from one source. A daisy-chain 
configuration connects multiple, linked devices from one output. When connecting PTZ cameras to a 
matrix switcher, for example, one set of cables connects the matrix switcher to each receiver, and 
then each receiver is connected to the next receiver.

This is the amount of time something happens in the system, such as the amount of time a camera 
view displays on a monitor, or an auxiliary is on.

The matrix switcher can automatically initiate macros or sequences based on time and date.

This is Pelco’s Coaxitron control technology that uses 32 bits to send a command.

A three-second camera scan (pan) followed by a three-second pause.

The auxiliary device remains on until a command is given (by a system operator or system 
automation) to turn it off. 

A user-selectable, variable number, which is associated with an actual physical camera input on the 
rear panel of the matrix switcher.

A sequence of commands or steps. Macros can be operated automatically or manually. Automatic 
operation can be based on specific times or dates (set through the Event Timer).
