Configuring the conference system via the central unit

System analysis – “Diagnostics” submenu

The “Diagnostics” menu item provides information on the status of the current and

voltage supply, on the status of data transmission and on interruptions due to

faulty cables or cable connections.

Displaying status information on the

current and

voltage supply –

“System Load”

Both ports can be subjected to undervol

tages, overcurrents and short-circuits:

If an error icon appears (see page 34), check your conference system for the errors

mentioned above.

Possible steps for error elimination:

• Eliminate the errors separately for each port.

• Calculate the maximum length of the cable string (see page 13) and, if neces-

sary, reduce the cable length.

• Reduce the number of conference units to 15-20

max. per cable string.

Display Meaning and causes

Current

An overcurrent in the central unit can be caused by

• metal parts (e.g. paper clips) that bridge the contacts of the plug

connections

• faulty conference units

• faulty system cables

• too long system cables

• too many conference units connected to one port

Voltage

An undervoltage can be caused by

• faulty conference units

• too long system cables

• too many conference units connected to one port

Current A short-circuit in the central unit can be caused by e.g.

• metal parts (e.g. paper clips) that bridge the contacts of the plug

connections

• faulty system cables

• wrong cables (e.g. crossover cables)

Voltage

The port is deactivated due to e.g.

• no conference units connected

• a short-circuit

If an error is detected at startup of the central unit, first eliminate the

error and then perform a manual self-test (see page 40) in order to check

if the error still occurs.

If an error has only occured during operation and has already been elim-

inated, this is automatically detected by the central unit.
