The AMG MUXcomm™ software is designed to allow monitoring of the status of the Guardian™ 2800 transmission units. It runs on a PC under Windows 95/98.

The AMG MUXcomm™ software allows the user to interrogate any Guardian™ 2800 connected to the PC. The connection to the PC can be via one of two means:

	Directly via the RS232 port on the rear of the Guardian™ 2800. This could be achieved remotely by means of a modem
	Remotely to any Guardian™ 2800 connected in a loop configuration so long as one of the Guardian™ 2800 in that loop is connected via it own RS232 port to the PC running the software. The main screen of MUXcomm allows the user to select any Guardian™ 2800 attached to the network.

It also provides the user with information on the status of the communication link between the PC and the targeted Guardian™ 2800 i.e. whether the target unit is responding, acknowledging, and returning information. Individual messages can be examined in detail in the message window. The main screen also allows the user to select from a number of System Status Screens which are as follows.

Communications Status
This screen provides the user with control of certain timeout parameters associated with the communication link between the PC and the targeted Guardian™ 2800. In addition messages may be monitored by diverting them to the PC and the communication ports can be reset.

Status Registers
This screen provides the user with all the information that is available regarding the status of the target Guardian™ 2800. Information includes:

	Software issue level
	Unit configuration
	Individual video input and output card status – whether present, whether video signal present
	Individual data card status – what is fitted, is data present
	Individual optical card status – parameters such as laser power, laser temperature, receiver power, etc
	Memory Status

This is the non-volatile EEPROM memory status of the unit. This memory stores various system configuration information and the look up table required when the remote switching and routing capability of the Guardian™ 2800 system is used.

Video Matrix Configuration
This screen allows the user to manually change the video matrix switch configuration within the target unit. The user can select any optical channel to be connected to any video output channel and any optical channel to be connected to any video input channel within the target unit.

Keyboard Control
For a Guardian™ 2800 network, if the network has been configured using the AMG MUXcomm™ configuration software, the user can select any camera number to any monitor number by a mouse operated soft keyboard provided on this screen.
