The following info is specific to V4.43 of the MSAT-IP firmware. For info about newer versions, see MSAT-IP.

The default settings that work best on the MSAT-IP changed significantly with firmware version 4.43. When upgrading the firmware from an earlier version, you may want to erase your settings and start over with the defaults.

Some of the following instructions will work as described only if both the firmware and RCI are V4.43 or later. You can check the versions of both from RCI's Help > About form.


Back up Existing Settings

If you already have the MSAT-IP set up and working, you might want to back up your existing settings first.

Using a Network Connection

If are running RCI (the management software that runs on Windows(tm) PC) and it is connected to the MSAT-IP using a network connection, you can simply use RCI's File > Backup Settings option. Select a filename and directory store the file in and click "OK".

Without a Network Connection

There are two options for recording your settings if you do not have a network connection:

 * Write them down manually.
 * Connect to the MSAT-IPs serial port using terminal software set for 115200 baud.  At the "root:~>" prompt run the command "reinit".  That will make a backup of your settings files.  If you wish to restore them later, type "undo-reinit" then "reboot".

Load the New Default Settings

With a Network Connection

To perform a restore click File, Restore Settings. The Restore Settings file is located at: "C:\Program Files\Link Communications\MSAT-IP" and has the file name "MSAT-IP Default Settings.mst".

Once you click Open it will send the new file over to the unit. When completed (it takes ~2 minutes) a prompt will indicate the changes are made. You then need to reset the unit by clicking the File > Reset MSAT-IP. This will now load the restored settings and the audio and other features will be ready.


Using RCI, you can manually enter the same settings that the defaults file contains. They are listed below. To get started, right-click on the name of one of the ports. That will open the "Advanced Radio Properties" form. At the top of that form, there are several tabs. The settings listed below are grouped by the tab which is used to set them up.

Note that the settings displayed correspond with the "port" number shown in the lower-left corner of the "Advanced Radio Properties" form. You can easily switch the port number using the controls shown there. You can ignore ports 5-12, if they are accessible at all. On MSAT-IP units with LMR (radio) support, the settings for ports 3 and 4 are important; otherwise they can also be ignored.

  1. This setting in the default file included with V4.43 may differ from the setting shown here, but the difference won't matter.

Radio Name

These settings affect only the labels you will see in RCI; they do not affect how the MSAT-IP operates. You can change them to anything you like.

Port Radio Name Radio Description
1 MSAT-G2 Port 1
2 MSAT-Hand Port 2
3 XTS-VHF Port 3
4 XTS-800Mz Port 4

Radio Type

Port Type Link Port Settings Ping Pong Prevention PTT Control Adaptive TX Audio Delay (note 1)
1 Link / Remote Base Full-Duplex 0.00 PTT Enabled Enabled
2 Link / Remote Base Full-Duplex 0.00 PTT Enabled Disabled
3 Link / Remote Base Half-Duplex (RX priority) 0.00 PTT Enabled Disabled
4 Link / Remote Base Half-Duplex (RX priority) 0.00 PTT Enabled Disabled


  1. The "TX Audio Delay (sec)" and "RX Audio Delay (sec)" settings can both be set to zero. On port 1, which has Adaptive TX Audio Delay enabled, the "TX Audio Delay" setting will change automatically.

RX Activity

Port Multiple Conditions Selected Access Conditions
1 Accept Any VOX (slow, threshold 3), Resource-Specific Activity
2 Require All Resource-Specific Activity
3 Accept Any VOX (med, threshold 10)
4 Accept Any VOX (slow, threshold 10)

Audio Levels

The default Tone Gain (20) and Voice Gain (50) settings are fine for all ports.

Port Transmit Gain Receive Gain
1 75 750
2 75 750
3 70 595
4 70 505

ID Messages

Leave disabled for all ports, unless needed for FCC compliance on ports 3 and 4.

This setting will be ignored automatically for non-repeater ports. The "Default for Port" preset can be selected if desired.

Basic Operation

To make the MSAT handset operate normally while connected to the MSAT-IP, ports 1 and 2 need to be placed into the same "group". The best method for doing this depends on which user interface style is connected. The user interface style can be selected by clicking on one of the "dots" with a "G" or "C" in the top right-right corner of the main RCI screen (not the Advanced Radio Properties form). The following instructions depend on which mode is selected:

Mode "G" (Grid Interface)

In the center of the screen you will find a grid of virtual green LEDs. They can be toggled on and off by clicking on them. Make sure the two shown below are turned on:

MSAT-IP_Setup Image

That will place ports 1 and 2 the MSAT radio and handset in group 1 so they will communicate with each other. If using the LMR version of the MSAT-IP, radios can be patched to the MSAT radio and handset by turning on the corresponding virtual LEDs in that same column.
