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.
Quoi de neuf dans la dernière version ?
- Supported with ID-5200A/E.
- Supported the display of 10 GHz band repeaters.
- Fixed a bug where the app would crash when displaying the map screen on devices running iOS 26 or iPadOS 26.
