Nd Cat - microHAM CW KEYER Manual

The CAT channel is used by the application software to control transceiver frequency, mode, T/R switching and
many other parameters. The application communicates with the radio using a serial protocol. Although most
modern radios implement some form of serial control, nearly every radio implementation is different. The degree
of control available for each radio depends on that radio and the application (logger or digital program).
NOTE: The port number assigned in Router MUST match the port number assigned in the host
application. First configure the virtual COM ports in Router then configure the application.
When a COM port is assigned in the Router but not in
the application (or the application is not running) Router
will indicate the channel is closed.
When an application opens the COM port assigned for control (usually at start-up), Router shows the channel as
open and displays baud rate, data bits, parity and number of stop bits used by the application. For example,
4800 8N2 means: 4800 baud, 8 bits data length, parity = none, and two stop bits.
Data flowing through the CAT channel is indicated by two arrows. A green arrow indicates data flow from the
host application to the radio and a red arrow indicates data flow from the radio to the application.
TIP: If the application provides for PTT (T/R) keying by radio control (CAT) turn this function OFF. PTT
by CAT is not reliable because RFI can prevent the radio from switching back to receive. There is a
dedicated T/R switching channel for this purpose called PTT.
NOTE: If your radio does not support handshake (most do not). Configure DTR and RTS settings in your
application program (logger) for Always On or Always Off. Do not select "Handshake."
For Router to determine the operating frequency and mode, it must know what radio (CAT protocol) being used.
To select the radio, click the Set button, choose your radio in the Radio combo box, select communication speed
in the Baud rate box, and set the CI-V address for Icom and some TenTec radios.
TIP: Disable the Autobaud function in any Icom transceiver used with Router. Configure the radio,
Router, and your application software to operate at 9600 or 19200 baud.
Disable router queries – When this box checked, Router will not poll the radio for frequency and mode when
that information is not available from the communication between the application and radio.
NOTE: "Disable router queries" disables Router polling only when the port has been opened by an
application program. When the virtual port is closed Router always polls the radio. If it is
necessary to disable all polling, select one of the "none" options in the Radio box.
WARNING: DO NOT select "Disable Router queries" unless you have a specific reason to do
so. Router does not interfere with logger polling and only polls for information that is not requested
by the logger. Disabling Router queries may result in incorrect frequency and/or mode decoding
and can have a serious impact on overall operation.
PW1 on radio bus – When this box checked, Router periodically generates an Icom "CI-V Transceive"
broadcast to keep the PW1 synchronized.
NOTE: Check this box only if you have an IC-PW1 or other Icom compatible accessory physically
connected in parallel with the transceiver.
Tracking: This function allows an external receiver to track the transceiver attached to CW Keyer.
NOTE: For specific information, please refer to Appendix C.
