About the DV Gateway function

Even if you cannot access a D-STAR repeater, you can make Gateway calls with the DV Gateway function. The function has two modes, the Terminal mode and the Access Point mode.

L Other stations can also directly communicate using the DV Gateway function, only if they use call sign routing. L When using the DV Gateway function, you cannot make a direct Local Area call.

D-STAR (Digital Smart Technology for Amateur Radio) is a digital radio protocol developed by JARL (Japan Amateur Radio League). In this document, the following transceivers are described. ID-31A PLUS/ID-31E PLUS/ID-51A (PLUS2)/ID-51E (PLUS2)/ID-52A/ID-52E/ID-50A/ID-50E/ ID-52A PLUS/ID-52E PLUS

L See page 2 for the combination of the transceiver and data cable. L The ID-52A/ID-52E is used as an example. L The ID-52A PLUS/ID-52E PLUS can simultaneously receive the Normal mode and the Terminal mode in the Dualwatch function.

IMPORTANT:

• Before operating in the Terminal mode or the Access Point mode, BE SURE to check your local regulations or laws.

• Register your call sign (MY) at a gateway server.*

• Register the Terminal/AP call sign that is set in the RS-MS3A, RS-MS3I, or RS-MS3W to the RS-RP3C

software as the access point.*

* Ask the gateway repeater administrator for details.

Terminal mode

The Terminal mode enables you to make Gateway calls through the Internet by using a Windows, Android, or iOS device that is running the RS-MS3W, RS-MS3A, or RS-MS3I application. In the Terminal mode, the transceiver does not transmit or receive RF signals through the antenna. The communication is routed through only the Internet.

The Access Point mode enables you to use another D-STAR transceiver and remotely*

make Gateway calls through an Access point transceiver when connected to a Windows, Android, or iOS device that is running the RS-MS3W, RS-MS3A, or RS-MS3I application.

NOTE: When using the DV Gateway function

• When operating in the Access Point mode, you need two call signs. One for the Access Point transceiver and one for the Remote D-STAR transceiver. (p. 6)

• You need an Internet connection with an IPv4 Global IP address. If you use a cellular system, you need an IPv4 Global IP address assigned to your Windows, Android, or iOS device.

About the UDP Hole Punch function

When both the caller station and the called station use the Terminal or Access Point mode, the caller station does not need to:

• Assign an IPv4 Global IP address to the router’s WAN port and forward port 40000 when connecting to the Internet using the router.

• Use a device assigned a static or dynamic IPv4 Global IP address.

L Information

• Depending on your Network environment, you may not be able to use this function.

• The caller station must set “UDP Hole Punch” to “ON” in the RS-MS3W/RS-MS3A/RS-MS3I to use this function. When not using this function, set “UDP Hole Punch” to “OFF.”

• A few minutes* after the call, the caller station cannot receive from the called station. In this case, the caller station must transmit to the called station again. * Less than 3 minutes, depending on the router.

NOTE:

• Use version of the RS-MS3W/RS-MS3A/RS-MS3I application software, as shown below. RS-MS3W: version 1.30 or later RS-MS3A: version 1.31 or later RS-MS3I: version 1.0.0 or later

• The caller station cannot communicate with the called station when:

- The caller station is using an earlier version software or firmware.

- The called station using an earlier version software or firmware.

- The called station calls through a local repeater instead of using the Terminal or Access Point mode.

• Even if using the latest version, the called station needs to forward port 40000 when connecting to the Internet using a router, or to use a device assigned a static or dynamic Global IP address to communicate with the caller station.

3. Port forwarding

When using a router, enable communication with the Internet, as described below.

z Forward the port number 40000 that is used in the RS-MS3W, RS-MS3A, or RS-MS3I. z “UDP” should be used as the port protocol. z Set a static local IP address in Procedure 2 (2. Setting a static local IP address to your device) as a destination

port.

L Ask the router’s manufacturer about how to forward the port. L Only one Windows, Android, or iOS device connected to the router can use the DV Gateway function at the same time.
