Overview

The purpose of this document is to detail the installation and configuration of a SpaceTrack4000 Antenna Controller Unit (ACU) for use with Lantronix appliances.

Terminology

Acronyms and abbreviations used in this document:

• ACU - Antenna Controller Unit
• M&C - Managing and Controlling
• BDU - Below Deck Unit

Configuring the Port

A few important items to note prior to configuration:

• The default baud rate for the Spacetrack M&C port is 9600.
• The default password for the BDU is FACTORY SETUP.

Once the Spacetrack BDU is properly connected to the Lantronix appliance, take the following steps to configure the port:

Open a connection to the Lantronix Local Manager and navigate to the port you wish to initialize.

[admin@LantronixLM]# port 1/1 
 native
[admin@LantronixLM (port 1/1)]# 

Use the config init command to configure the M&C port on the Spacetrack 4000. The make and OS should both be set to Spacetrack. Model and OS version are not required.

[admin@LantronixLM (port 1/1)]# config init
--- Enter New Values ---
description: []: 
make: [native]: Spacetrack
model: []: 
os: []: Spacetrack
os version: []:
management IP: []:  
Configure dedicated Ethernet port? (y/n) [n]: 
console username: []:  
console password []: FACTORY SETUP
confirm password: FACTORY SETUP
enable username: []:FACTORY SETUP
enable password []:FACTORY SETUP
serial bit rate [9600]: 9600
serial data bit [8]:
serial parity [none]:
serial stop bit [1]:
serial flow control [none]:
Do you want to commit these changes? (y/n): y

When the config init command completes, run terminal to open a terminal session with the Spacetrack ACU. The Lantronix appliance will locally echo the commands to make interactions easier.

[admin@LantronixLM (port 1/1)]# terminal
Press ~[ENTER] to exit 
Connecting ... 
beginning pull of running-config
running-config saved to archive as current.
Console session started.

If the port has been properly configured, you will be able to interact with the ACU using standard command codes. If you are not able to interact with the 4000 ACU using the appropriate command codes, ensure that the physical connection is correct and that the serial settings on the Lantronix appliance match those on the 4000 ACU. Use the escape sequence (~[ENTER]) to exit the terminal session with the ACU.

Automated Functions

Automated jobs are scheduled using default frequency during the config init process. For the Spacetrack ACU, these jobs include pullRunningConfig and deviceInfo.

Running Config

The 4000 ACU has one configuration file that is pulled by the pullRunningConfig job and is stored on the appliance as the running-config. To pull this file manually, use the pull running-config command.

[admin@LantronixLM (port1/1)]# pull running-config
beginning pull of running-config
running-config saved to archive as current.

Configuration Rollback

The Spacetrack ACU driver includes support for Surgical Rollback. When the terminal command is run, the appliance will pull the device configuration before giving control to the user. After the terminal session is closed, the device configuration will be pulled again and compared to the original. If the session was terminated unexpectedly, any changes will be rolled back. Otherwise, the user will be presented with the options to commit or rollback any changes made.

Configuring Monitors

There are two monitors that are automatically scheduled when a port is configured as a Spacetrack ACU:

• gps: Collects latitude and longitude information from the ACU.
• remotestate: Collects information on key variables including azimuth, relative azimuth, cross level, AGC, AGC threshold, and polarity angle.

The monitors are scheduled to run at 30 second intervals by default. If you would like to change the monitor interval, simply reschedule the monitor with the appropriate delay. The syntax for scheduling a monitor is:

config monitors <object> <interface> [ruleList] [:delay]

To schedule the monitors for the Spacetrack ACU, navigate to the port of the device to be monitored.

[admin@LantronixLM]# port 1/1
SpaceTrack 4000 
SpaceTrack4000

Use the config monitors command to schedule the specific monitor.

[admin@LantronixLM (port1/1)]# config monitors gps :60
Job was scheduled 1: [Interval: 60 Seconds; Mask: * * * * *] rulesMonitor gps

GPS information is now being monitored.

[admin@LantronixLM (port1/1)]# config monitors remotestate :30
Job was scheduled 2: [Interval: 30 Seconds; Mask: * * * * *] rulesMonitor remotestate
remotestate information is now being monitored.

Displaying Monitors

To display monitor data, use the show command from the port. The command syntax is:

[admin@LantronixLM (port 1/1)]# show monitors

The result will display index number, time interval and mask, interface name, applied rules, and delay time.

1: [Interval: 00:00:60 Mask: * * * * *] rulesMonitor gps none "" 60
2: [Interval: 00:00:30 Mask: * * * * *] rulesMonitor remotestate none "" 30

Displaying GPS Data

The GPS monitor is displayed in three parts: events, most-recent, and position. These extensions are required for display of the GPS data. The extensions are described below:

• Events: Shows GPS coordinates associated with Lantronix events
• Most-recent: Displays the most recent valid GPS coordinate
• Position: Displays the GPS coordinate history

Examples of the three GPS monitors:

[admin@LantronixLM (port1/1)]# show gps events
GMT      Latitude             Longitude        Context  Message

Displaying Device Syslog

To display syslog information for the SpaceTrack 4000, use the show device syslog command from the port. This command will display currently stored syslog data. The command syntax is:
