*** Requires a corTalk® uGI1 to use. *** Contact us at 'sales.ugi1@mobiltex.com' to purchase. This app is for configuring the uGI1 (Micro GPS-enabled Interrupter 1). The uGI1 is used to monitor and control a cathodic protection rectifier by switching a relay at precisely scheduled intervals. This app allows access to basic information on the uGI1 and allows setting up 10 different profiles to meet the customer's needs. Note that logs, due to their size, can only be extracted from the uGI1 using the PC configuration application through the USB port. The app has three tabs, a 'Settings' tab, 'Profiles' tab and 'Live Profile' tab. The 'Settings' tab allows for seeing a detailed status of the device, any recent faults that have arisen, manually setting the Real Time Clock (RTC), setting the unit's name, adding notes and rebooting the device. The 'Profiles' tab allows for the custom configuration of up to 10 independent profiles. It can read/write them from/to the unit and set their values. In addition, the profiles can be reset to their default values. The 'Live Profile' tab gives real time live information on the uGI1 Profile. The uGI1 must initially be put in Bluetooth pairing mode and a pairing code entered on the app. The pairing code (default=123456) can be found and changed with the PC configuration application. Once paired, the iOS device can reconnect without needing to re-enter the code or put the uGI1 back into pairing mode. Only iOS devices supporting Bluetooth 4.0 (LE) can connect to the RBT1 with this app. (iPhone 4S and newer and iPad 3rd gen and newer)

Automatically set the transceiver’s “FROM” and “TO” fields by tapping a repeater site or a station on the map. Receive History In the DV mode, read and edit the received station’s information. Download additional information from an Internet database, such as QRZ.com or APRS.fi. Text messaging Send and receive text messages. Call Sign list Edit call signs and names used in the DR function.

Export Export a Repeater list, a Call Sign list, or Receive History. See the transceiver’s instruction manual for details. The instruction manual can be downloaded from the ICOM web site. Device requirements The RS-MS1I operating requirements are as follows: iOS16 or later Usable transceivers (As of May 2026) - ID-4100A/E + Bluetooth unit (UT-137) - ID-52A or ID-52E *1 - ID-52A PLUS or ID-52E PLUS *2 - ID-5200A or ID-5200E *3 - IC-705 *4 *1 Supported in RS-MS1I Ver.1.1.0 or later. *2 Supported in RS-MS1I Ver.1.3.0 or later. *3 Supported in RS-MS1I Ver.1.4.0 or later. *4 Supported in RS-MS1I Ver.1.2.0 or later. Preparation To use the RS-MS1I with a supported transceiver, you need an optional Bluetooth unit. See your transceiver’s instruction manual for details. Transceiver’s settings Set the following functions as shown below to use the RS-MS1I. [Function] > [CI-V] > [CI-V Transceive]: ON [Bluetooth Set] > [Data Device Set] > [Serial Port Function]: CI-V (Echo back OFF) Note: - The RS-MS1I may not work with all iPhones or iPads, even if they are one of the tested devices. This is because an application program on your device may conflict with the RS-MS1I. - The RS-MS1I may not be used, depending on the OS version, installed application, and so on. - Bluetooth LE is used for the connection with the transceiver, so there may be a time delay between the transceiver’s operation and the display on the iPhone or iPad. - When sending or receiving pictures using “FAST mode,” the headset audio will be temporarily interrupted because of the transceiver’s Bluetooth unit limitations. - You may need to connect to the Internet through a Wireless LAN, an LTE network or a 5G network for some functions. - The RS-MS1I supports only portrait orientation with the iPhone. It does not support Auto Rotate. However, landscape orientation and Auto Rotate are supported with the iPad.
