18 TROUBLESHOOTING
Symptom
Unable to communicate with
ARCP-890/ARHP-890 using the LAN
port. (For operation within the LAN)
Unable to perform PC keying in the
CW mode using the USB port. Or
unable to transmit.
Unable to perform PC keying in the
RTTY mode using the USB port. Or
unable to transmit.
When this transceiver is connected to
a PC with a USB cable, the COM port
number assigned to the PC becomes
larger.
Clock correction by the NTP server is
not performed.
Date and time cannot be configured.
18-6
Probable Cause
① The IP address cannot be acquired.
② The IP address of this transceiver is not
configured in ARCP/ARHP.
③ The administrator ID, password and the LAN
connection are not configured.
④ The users to be connected are not registered
in the KNS user list.
① CW keying is not configured.
② PTT is not configured.
③ The PC application settings are wrong.
① RTTY keying is not configured.
② PTT is not configured.
③ The PC application settings are wrong.
When our transceiver (TH-D72/TS-590S/
TS-590SG/TS-990S/TS-890S/TH-D74) is
connected to a USB port that is different from
the previously connected port, the OS will
assign a new COM port.
The IP address cannot be acquired.
The NTP server address is not configured.
NTP information is not transmitted from WAN. Open the port of communication devices such
LAN cable is not connected.
Auto clock correction is ON.
Corrective Action
① Same corrective actions as the
correction by the NTP server is not
(18-6) symptom.
② Configure the IP address of this transceiver
in the ARCP/ARHP.
③ Configure the administrator ID, password
and "KNS Operation (LAN Connector)" in the
KNS menu.
④ Register the information to the KNS user list.
① Configure Advanced Menu [20] "Virtual
Enhanced COM Port - DTR" to CW keying.
② Configure Advanced Menu [19] "Virtual
Enhanced COM Port - RTS" to PTT.
③ Reconfigure the PC application settings as
follows.
a. Check that the COM port number assigned
by the Device Manager of the OS for
communication between this transceiver and
the PC application is the same as the number
specified by the PC application.
b. Check that the keying output and PTT output
are the same as those configured in ① and ②
respectively.
① Configure Advanced Menu [20] "Virtual
Enhanced COM Port - DTR" to RTTY keying.
② Configure Advanced Menu [19] "Virtual
Enhanced COM Port - RTS" to PTT.
③ Reconfigure the PC application settings as
follows.
a. Check that the COM port number assigned
by the Device Manager of the OS for
communication between this transceiver and
the PC application is the same as the number
specified by the PC application.
b. Check that the keying output and PTT output
are the same as those configured in ① and ②
respectively.
With our transceiver unit connected to the PC,
delete the unwanted COM port number from
"Device Manager" of the OS. For more details,
please refer to the website below.

Check whether the DHCP of this transceiver is
configured to ON.
Check whether the DHCP server function on
the broadband router is configured to ON or
whether it is functioning normally.
Configure the NTP server address.
as the broadband router to ensure that the port
used for communicating with the NTP server is
not blocked.
Check the LAN cable connection.
Set auto clock correction to OFF.
