CEFD CDM-570 Serial

The CDM-570 Serial is a Comtech EF Data's entry-level satellite modems and operates at L-band and includes support for externally connected Block Upconverters (BUCs) and Low-Noise Block Downconverters (LNBs).

About

This connector is intended to communicate with CDM-570 Serial devices using serial commands as described in the device manual.

Note: This connector will export a different connector based on button FSK Enabled. A list can be found in the section 'Exported Connectors'.

Configuration

Connections

Serial Connection - Main

This connector uses a serial connection and requires the following input during element creation:

SERIAL CONNECTION:

  • Interface connection:

    • IP address/host: The polling IP of the device.
    • IP port: The IP port of the device.
    • Bus address: The bus address of the device.

Usage

Version 2.0.0.14

Start Page

On the Start page, you can access some of the device's parameters. Some of them can be set and others are of type read-only.

  • Equipment ID . - Shows available hardware and functionality options installed on the device.
  • Alarm Mask . - Alarm mask conditions.
  • Interface Settings . - RTS and Line Build Out configuration.
  • Utilities . - Some others options.
  • Normalized Value . - Set a value to normalize Rx Eb/No.

Configuration

Use this page to configure the modem operating Modulator and Demodulator parameters.

After setting the desired values you must enter the Send Configuration page button. If the values are correct press the Send Config button. Back to the Configuration page if you want to see again the values present in the device, press the Refresh button.

Modem Lineup

In this page press the Refresh Values button if it's necessary to read the latest values from device. This is useful when you don't want to wait for the next update performed by the timers.

It is also possible, in this page, to analyze the response of a command sent to the device. The code of each command is defined in the manual (Appendix D. Serial Remote Control). For example, to know the temperature in the device write "TMP?". To set the date 17-12-2013 write "DAY=171213".

Modulator/Demodulator

Use this read-only page to view information about the modem operating Modulator and Demodulator parameters.

Frame

Use this page to view and set EDMAC and AUPC related parameters.

Stored Statistics / Events

Use this page to configure the Statistics Sample Interval and to analyze statistical information.

It's also possible to see information about device Events under the Stored Events . page button.

Dynamic Threshold

There are two parameters in the Start Page - Rx Eb/No Status and Rx Remote Eb/No Status - that will trigger an alarm when the values of Rx Eb/No and Rx Remote Eb/No go beyond certain values. These values are described in the Dynamic Thresholds Table. So, if Rx Eb/No and Rx Remote Eb/No have values under EbNo_min and above EbNo_High a Critical Low or Critical High Alarm, respectively, will be triggered. Inside the limits, Rx Eb/No Status and Rx Remote Eb/No Status will be set as Normal.

To define these values you need to create a file under the path "C:\Skyline DataMiner\Documents\DMA_COMMON_DOCUMENTS\Lineuplevels\ with .csv extension. After that, in the DMA Element, press the Refresh File List button. The Channels CSV-File Path will show the name of the file. Then press Load File.

If device parameters Rx Coded, Rx Modulation and Rx FEC are the same as the ones described in the file then a row will be shown in the table and the alarms will be set.

Version 3.0.0.8

Admin - Summary

Use this read-only page to obtain information for the assigned MAC and IP Addresses and the currently available standard and optional operational features.

  • MAC Address (read-only): This is set at the factory to a guaranteed unique address that cannot be modified. The MAC address for the Ethernet interface.

  • IP Address/Mask: The IP address/mask for the IP Module Ethernet Interface.

  • Toggle Polling Speed: Switch between Fast Polling and Normal Polling of the parameters.

Modem

Use this page to configure the modem operating (Tx/Rx) parameters. Enter a preferred value into a text box, select a predefined parameter from a drop-down menu or, for the Alarm Mask section, use the provided button to define a designated alarm as Masked or Active.

With AUPC, a local modem is permitted to adjust its own output power level in order to attempt to maintain the Eb/N0 at the remote modem.

  • Framing: Use the drop-down menu to select a value: Unframed, EDMAC and EDMAC 2.
  • AUPC: Use the toggle button to select AUPC operation as either Off or On.
  • Rem Demod Target Eb/N0: Type in a value, in dB, from 0.0 to 14.9.
  • Tx Power Max Increase: Use the drop-down menu to select a value, in dB, from 0 to 9.
  • Max Pwr Reached Action: Use the drop-down menu to set the action as No Action or Generate Tx Alarm.
  • Rem Demod Unlock Action: Use the drop-down menu to set the action as Go to Nominal Power or Go to Maximum Power.

Modem - Utilities

Use this page to set utilities such as Date and Time and Circuit ID, and to Load or Store Configuration presets.

  • Re-Center Buffer: To force the re-centering of the Plesiochronous/Doppler buffer.

  • Force 1:1 Switch: To toggle the Unit Fail relay to "fail" state for approx. 500ms. If the unit is one in a 1:1 redundant pair and it is currently the online unit, this forces a switchover so the unit is then placed in standby mode. The command is always executed by the unit, regardless of whether it is standalone, in a 1:1 pair, or part of a 1:N system.

  • Load/Store Configuration: To Load (recall) and/or Store up to 10 configuration sets numbered 0 through 9.

  • Date & Time: Use the format MM/DD/YY to enter the Date (where MM = month [01 to 12], DD = day [01 to 31] and YY = year [00 to 99]). Use the international format HH:MM:SS to enter the Time (where HH = hour [00 to 23], MM = minutes [00 to 59], and SS = seconds [00 to 59]).

    Use Time Sync page button to set the Time Synchronization related parameters.

  • Circuit ID Configuration: Create a Circuit ID string of up to 24 alphanumeric characters.

  • Clocks: Configure Tx Clock Source, Rx Buffer Size, Modem Frequency Reference, G.703 Clock Extended Mode, and G.703 Clock Extend Interface.

  • Internal Reference:

    • Warm Up Delay: For internal frequency reference (OCXO). Disabled (instant on - no delay for OCXO to reach temperature) or Enabled (unit waits until OCXO reaches correct temperature)

    • Warm Up Countdown: Used to truncate the Warm-up delay period to zero, forcing the unit into 'instant-on' mode. As a query, returns the Warm-up Delay countdown, in seconds remaining. Range is from 000 to 200 seconds.

  • Terrestrial Interface:

    • Interface Type: Used to define which electrical interface type is active at the data connectors. If RS422, V.35, or RS232 is selected, the menu also indicates the operation of RTS/CTS.
