TROUBLESHOOTING .............................................68–75 The settings in this section are necessary only when using: (As of November 2016) • IC-7851 • IC-7850 • IC-7800 (firmware version 3.00 or later ) • IC-7700 (firmware version 2.00 or later)

❍ The RS-BA1 consists of the Remote Utility, used to configure a remote control system, and the Remote Control- ler, used to send CI-V commands to a radio to remotely operate it. ❍ With the RS-BA1, you can configure a remote control system through the Internet, or a LAN. ❍ The RS-BA1 provides highly qualified audio communication between your PC and an Icom amateur radio through a USB port (Type B/Mini-B) or LAN port*. • You can also control Icom radios with an RS-232C interface. * If you use the IC-7700, firmware version 2.00 or later installed, is required. If you use the IC-7800, firmware version 3.00 or later installed, is required. About the remote control system An RS-BA1 remote control system basically consists of following three components: • Base station (Radio and Server) • Network (Internet or LAN) • Remote station (PC) The Remote station controls the Base station radio through the network (internet or LAN). To control the Base station radio, the radio should be connected to the network through a PC or directly. Most Icom radios need a PC, and use the PC as the Server to exchange CI-V commands, control command and audio with the Remote station through either the internet or LAN. (Fig. 1) The radio has a built-in Network function that can be directly connected to the network. With this function, a Base station PC is not necessary. (Fig. 2) The radio is remotely controlled by the Remote station PC using the Remote Controller. See the “5. REMOTE CONTROLLER’S BASIC OPERATION” section for more details.

29 ■ When configuring the remote control system through the Internet If you configure the remote control system through the Internet, Remote stations can access the Server using its public IP address. If you utilize a Dynamic DNS service, Remote stations can access the Server by not only its public IP address, but also by its domain name. D To let Remote stations access the Server using its public IP address A public IP address is an address that is accessible over the global Internet. If you use a dynamic public IP address, it is chosen from a pool of available addresses and changes each time you connect to the Internet. Because of this, Remote stations will have to match the IP address each time to access the Server. If you use a dynamic public IP address, we recommend that you utilize the Dynamic DNS service to allow the Re- mote stations to access the Server using its domain name, or use a static public IP address. Ask the router’s manufacturer about how to configure your router to set the public IP address. IP address: 192.168.0.100 Computer name: Base PC IP address WAN: 888.888.888.888 LAN: 192.168.0.1 PC Icom radio PC (Server) Router Router Request “888.888.888.888” (Public IP address) Internet Internet Base station Remote station

30 D To let Remote stations access the Server by its domain name If you set up an account for a Dynamic DNS server, you can configure your router to update the Dynamic DNS server with your dynamic IP address. Even if you don’t have a static public IP address, you can allow Remote sta- tions to access the Server through the Internet, using its domain name. Ask the router’s manufacturer about how to configure your router to use the Dynamic DNS services. Dynamic DNS server Update with your dynamic IP address IP address: 192.168.0.100 Computer name: Base PC IP address WAN: 888.888.888.888 LAN: 192.168.0.1 Domain name Icom-rsba1.com PC Icom radio PC (Server) Router Router Request “Icom-rsba1.com” (Domain name) Internet Internet Base station Remote station ■ When configuring the remote control system through the Internet (Continued)

44 If you configure the remote control system through a LAN, Remote stations can access the Server using its IP ad- dress. The example below describes how to find out the Base station’s IP address, to be requested by Remote stations. ■ When configuring the remote control system through a LAN IP address: 192.168.0.10 Network Name: IC-7851 PC Request “192.168.0.10” (IP address) or “IC-7851” (Network Name). Router Base station Remote station IC-7851 IC-7850 IC-7800 (firmware version 3.00 or later) IC-7700 (firmware version 2.00 or later) (Radio/Server) D To let Remote stations access the Server using its IP address An IP address is a numerical label that is assigned to devices participating in a computer network. Check your radio’s IP address to let Remote stations access the Server. q Hold down [EXIT/SET] for 1 second to select the Set mode menu screen. w Push [F-5•OTHERS] to enter the Others set mode. e Push [F-1•▲] or [F-2•▼] to select “IP Address.” r Check the IP address that is displayed in the IP Ad- dress field. (Example: 192.168.0.10) Check t Push [EXIT/SET] twice to exit the Set mode. D To let Remote stations access the Server using its network name A network name is an identification information as- signed to each device participating in a computer net- work. Check your radio’s network name to let Remote sta- tions access the Server. • This function is only for the IC-7850 and IC-7851 transceiv- ers. q Hold down [EXIT/SET] for 1 second to select the Set mode menu screen. w Push [F-5•OTHERS] to enter the Others set mode. e Push [F-1•▲] or [F-2•▼] to select “Network Name.” r Check the network name that is displayed in the Network Name field. (Example: IC-7851) t Push [EXIT/SET] twice to exit the Set mode. Check For the IC-7850 and IC-7851 users: The DHCP function is set to ON as default. We recommend that you assign the server using the network name. If you want to assign the server using an IP address, set the “DHCP” item OFF in the Others set mode.

45 D To let Remote stations access the Server by its domain name If you set up an account for a Dynamic DNS server, you can configure your router to update the Dynamic DNS server with your dynamic IP address. Even if you don’t have a static public IP address, you can allow Remote sta- tions to access the Server through the Internet, using its domain name. Ask the router’s manufacturer about how to configure your router to use the Dynamic DNS services. Dynamic DNS server Update with your dynamically changing IP address IP address: 192.168.0.10 IP address WAN: 888.888.888.888 LAN: 192.168.0.1 Domain name Icom-rsba1.com PC Router Router Request “Icom-rsba1.com” (Domain name) Internet Internet Base station Remote station IC-7851 IC-7850 IC-7800 (firmware version 3.00 or later) IC-7700 (firmware version 2.00 or later) (Radio/Server) ■ When configuring the remote control system through the Internet If you configure the remote control system through the Internet, Remote stations can access the Server using its public IP address. If you utilize a Dynamic DNS service, Remote stations can access the Server by not only its public IP address, but also by its domain name. D To let Remote stations access the Server using its public IP address A public IP address is an address that is accessible over the global Internet. If you use a dynamic public IP address, it is chosen from a pool of available addresses and changes each time you connect to the Internet. Because of this, Remote stations will have to match the IP address each time to access the Server. If you use a dynamic public IP address, we recommend that you utilize the Dynamic DNS service to allow the Re- mote stations to access the Server using its domain name, or use a static public IP address. Ask the router’s manufacturer about how to configure your router to set the public IP address. IP address: 192.168.0.10 IP address WAN: 888.888.888.888 LAN: 192.168.0.1 PC Router Router Request “888.888.888.888” (Public IP address) (Radio/Server) Internet Internet Base station Remote station IC-7851 IC-7850 IC-7800 (firmware version 3.00 or later) IC-7700 (firmware version 2.00 or later)
