P300 Modem front panel view

Keyboard

The keyboard is of the membrane type (an integral part of the front panel) which provide a direct tactile feel. There are 15 keys in total - number keys in the range 0 to 9, an up arrow key ( ), down arrow key ( ), MAIN key, YES/ENTER key, and NO/PREV key.

This backlit display provides 2 lines of 40 characters each and is highly legible even in conditions of high ambient light. The LCD provides detailed information about the status and configuration of the unit, and when appropriate, prompts the user to enter data via the keypad.

The circular monitor port available on the front panel of previous products has been moved to the rear panel and is now combined onto the Async ESC connector (a `D` type connector instead of the difficult to obtain 8 pin `din` audio type connector). See the description of the “Async ESC connector” under the rear panel description which starts on the next page.

LED's indicate a fault, pressMAIN, then select Status		Amber: Loopback or Test mode active
		Off:	Normal (Tx carrier on)
to display the current fault condition.
		Amber: Tx carrier off or Standby of 1:1

In normal operation there should be three GREEN LED'sshowing.

If the Status is RED, the unit has failed due to internal or possibly external conditions. Refer to the text on the LCD Status screen and rectify if possible.

If the TX OK or RX OK LED's are off, then the Tx or Rx traffic has failed due to an external fault, again refer to the text on the LCD Status screen and rectify if possible.

If the TEST LED is AMBER, a test mode or loopback is active, press MAIN, and select Test to

'query or change the test settings.

If the STANDBY LED is Amber, the Tx carrier is off. It may be intentionally switched off, or it may be muted due to either a fault, an external mute signal, or if in a 1-FOR-1 redundant pair it may be the standby unit.
