CEFD CDM-570A Serial
The CDM-570 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 implements the parameters like in the previous CEFD CDM-570 Serial connector which was based on the previous web interface.

Configuration
Connections
SNMP CONNECTION:
- IP address/host: The polling IP of the device, e.g., 10.11.12.13.
SNMP Settings:
- Port number: The port of the connected device, default 161.
- Bus address: The bus address. This is the address that will be used for the serial communication.
How to Use
Admin - Summary
This page contains the available information for the admin, it contains the ethernet settings.
Modem
Use this page to configure the modem operating (Tx/Rx) parameters, including the Tx/Rx Interfaces and Framing. 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/YYYY to enter the date (where MM = month [01 to 12], DD = day [01 to 31] and YYYY = year).
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]).
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.
- RTS: Defines how RTS/CTS will operate at the main data interface
- Line Build Out: Valid only for T1 interface.
Modem - Status
Use this read-only page to view information about the modem's general operating status and configuration parameters. Installed Options: This read-only section provides information for additional installed options.
Modem - Logs
Use this read-only page to view Faults and Alarms (i.e., Modem Events) as logged by the unit, and to view modem operating statistics.
- Clear Events: To delete all existing log entries from the Modem Events Log. The log is then reset to one (1) entry: "Info: Log Cleared".
- Initialize Events Pointer: To Initialize the Events Pointer of the Modem Events Log.
- Clear Statistics: To delete all existing entries from the Modem Statistics Log.
- Initialize Stats Pointer: To Initialize the Stats Pointer of the Modem Statistics Log.
Modem - BUC/LNB
Use this page to configure Block Up Converter parameters and to display the BUC status for L-Band operation and to configure Low-Noise Block Down Converter parameters and to display the LNB status for L-Band operation. In version 1.0.1.4, it's possible to enable and disable polling of these parameters.
- Poll BUC/LNB Parameters - Enable or Disable the BUC and LNB polling.
BUC Configuration:
- Use the provided toggle buttons to turn BUC DC Power Control, 10 MHz Reference, RF Output and Communication Enabled or Disabled.
- BUC Low and High Current Limit value ranging from 0 to 4000 mA.
- BUC Lockout Frequency from 3000 to 65000 MHz and designate the value as a HIGH (+) or LOW (-) limit.
- BUC Address from 0 to 15.
BUC Status: The values displayed in this section are read-only and cannot be changed.
LNB Control:
- **DC Supply Voltage:**Off or On with 13, 18 or 24 V.
- LNB 10MHz Reference: Enable operations Disabled or Enabled.
- Assign LNB Current Lower and Current Upper Alarm Limit values ranging from 10 to 600 mA.
- Assign an Rx Lockout Frequency and designate the value as a HIGH (+) or LOW (-) limit.
LNB Status: The LNB Current and LNB Voltage values displayed in this section are read-only and cannot be changed.
