TROUBLESHOOTING 18 Problems Related to Data Communication, PC and Network Symptom Probable Cause Corrective Action Errors and retries occur frequently during transmission in the DATA mode. The audio output level of the auxiliary equipment is too high and modulation signals are distorted as a result. Lower the output of the auxiliary equipment such that the ALC zone is not exceeded. The audio input sensitivity of the data communication terminal on this transceiver does not match the input signal. Adjust the audio input sensitivity of the data communication terminal in menus [7-06] (USB) and [7-07] (ACC 2) such that the ALC zone is not exceeded.

Transmit signals using one of the following methods. a. Transmit by controlling the PKS terminal of The method of transmission is not appropriate. the ACC 2 connector. b. Transmit using the [PF] key configured for the DATA SEND function. c. Transmit using the "TX1;" PC command. The level of the audio input to the data communication terminal is low. Raise the audio output level of the connected auxiliary equipment, or raise the audio input level of the terminal in use in menus [7-06] (USB) and [7-07] (ACC 2). Errors occur frequently during reception in the DATA mode.

There is multi-path distortion or fading at short When using a beam antenna, change the intervals. (The RX signal strength is not orientation of the antenna to look for a position necessarily the best when it is strongest.) that is less likely to cause errors. Unable to communicate with ARCP-890 or ARHP-890 using the COM port. The baud rates do not match each other. The COM port is unable to handle CTS/RTS. Check the baud rate of the TS-890S and ARCP-890. Configure Advanced Menu [16] "PSQ/PKS Pin Assignment (COM Connector)" so that the COM port can handle CTS/RTS. Unable to communicate with ARCP-890 or ARHP-890 using the USB port. The driver is not installed on the PC. Download the driver from our website and install it on the PC. The correct driver is not installed on the PC Reinstall the driver. because the PC is connected to this transceiver before the driver is installed. The baud rates do not match each other. Check the baud rate of the TS-890S and ARCP-890. ① Flow control is not configured. ① Check that Advanced Menu [17] "Virtual ② The COM ports of PC and ARCP/ARHP are Standard COM Port - RTS" is configured to not matching. "Flow Control". ② Check that the COM port number assigned by the Device Manager of the OS for communication between this transceiver and ARCP/ARHP is the same as the number specified by ARCP/ARHP. (ARCP/ARHP uses the Standard COM port number displayed in the Device Manager of the OS.) Refer to 16-7 16-7 8-1 1-7 16-2 1-4 16-5 16-7 16-7 16-5 16-8 16-5 16-5 16-5 1-5 16-12 18-5
