1.238 Evertz-7708-LR

This page describes the device driver and the device window for the Evertz 7800 Chassis LR7708 Series Wideband Receiver cards type:

• 7708LRA,
• 7708LR-H,
• 7708-LR

The driver was tested with the following cards:

• Model: 7708LRA
• SW: 1.12 Build 120

Please note: Parameters of the corresponding transmit card are not implemented. Use separate 7708-LT driver on the opposite chassis.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

• --- Shows all parameters of the LR card.
• --- The faults page.
• --- The device info page.
• --- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the controller.

• parameter --- description

• address --- The SNMP address specification for the device. The full address specification consists of the following fields:aaa.bbb.ccc.ddd:pppp read-community write-community

  • aaa.bbb.ccc.ddd --- The IP address of the device in 'dotted quad' notation. This field is mandatory.
  • pppp --- The IP port number where the device accepts SNMP requests. The port number may be omitted, the driver uses the standard port 161 in this case.
  • read-community --- The SNMP read community name. This must match the read community expected by the device.
  • write-community --- The SNMP write community name. This must match the write community expected by the device. The write community name may be omitted, the driver uses the read community name for both, read and write in this case. If both community names are missing, the driver uses 'public' as a default for read and write community.

• agcMode --- Defines the gain mode of the card:

  • AGC: Maintains a constant output level even if the rf input level changes as long as in AGCs hold range.
  • IGC: Compensates optical loss and outputs rf signal proportional to what is coming into the transmitter card.
  • MANUAL: User selectable fixed gain for rf levels.

• agcLevel --- Defines the target output level when in AGC mode.

• squelch --- Defines if squelch is activated or not

• squelchThreshold --- Defines the threshold for transmitters cards rf input level. Works only with compatible cards which send monitoring information to receive cards.

• slot --- Defines the slot number where the card is installed. Setting this parameter is indispensable for correct communication
