After updating the transceivers firmware to the latest version that supports the Portable Digital Node Function the SCU-40 cable kit will allow a user to easily establish and operate a WiRES-X Portable Station by directly connecting the FTM-400XD or FTM-100DR to the USB and audio ports of a PC. In this configuration the conventional HRI-200 internet interface kit is not required for the Portable Digital Node function, and no fixed or dynamic global IP address is necessary. Since users do not need to open an Ethernet port, WiRES-X communication from any location is possible - such as Hotel rooms, Airports, Vehicle Wi-Fi, or even Wi-Fi Access Points.

Using this new Portable Digital Node Function, users can gain access to the WiRES-X Network directly by using the transceivers PTT and microphone. The need to have an additional radio to talk to a node radio is no longer needed in order to enjoy the WiRES-X Network. Using the SCU-40 cable kit the transceiver can also function as an Access Point for RF communication identical to any previous WiRES-X node.
