Kenwood TS-480 manual Accidental continuous TX, Setting up KNS on the Arcp side

Page 49

When the system is operating, RX audio and the commands that control ARCP are sent from the host PC, along with the TX audio and commands controlling the transceiver.

Using this combination of ARCP-480 and ARHP-10, in order to be able to communicate by voice, and to be able to hear the sidetone when keying, both the host PC and remote PC must be running Windows® 2000 (SP3 or later) or Windows® XP (SP1 or later). For voice exchanges, the remote PC must be connected to a microphone for TX audio input, and to a speaker for receiving audio. These are both plugged into a sound card.

Accidental continuous TX

Inasmuch as KNS is a network-based method for performing remote control over a network, it is possible that, through some malfunction, the TS-480 installed on the host end might go into continuous transmission accidentally.

By setting the time-out timer on the TS-480, it is possible to ensure that, after the set time period has passed, the transceiver will automatically switch back to RX mode. The timer count always starts with the commencement of transmission, so even in the case of a prolonged but intentional transmission, after the set period has passed it will switch back to RX; nevertheless, it is a good way to prevent the transceiver from going into continuous TX mode.

In the event that, following the start of transmission, some network problem arises that prevents you from executing the command for the transceiver to switch back to RX, the ARHP-10 software itself is equipped with a function* that, after the passage of a fixed period of time, will switch the transceiver back to RX mode. However, please make sure that you can obtain rapid access to the host if a malfunction occurs.**

*This software cannot handle every problem that may occur. **In Japan only. For details, refer to the laws governing radio transmissions.

Setting up KNS on the ARCP side

First check the LAN/WAN. Ensure that everything is set up correctly, referring to the second section on ARHP10, ARCP-480 Help, and the instruction manuals for your network devices.*

Before setting up the host side for KNS, you should first check with the administrator of the host computer and obtain all necessary information. This includes the KNS host address, the command port number, user name and password, and guidance on how to connect the audio cable.

Within the setup window, you should fill in the necessary information in the KENWOOD NETWORK COMMAND SYSTEM frame. If the

To: combo box is empty, this means that no KNS host has been selected. You should input the host for the connection using the Setting and Add buttons.

In the KNS Connection Settings window, you should input the name of the other computer as the connection name, together with its description. For the address, input the IP address of the other computer. You must also input user name and password. If you are going to use voice
