The CAT channel is used by application software to control transceiver frequency, mode, T/R switching and
many other parameters using a serial (CAT) protocol. Most modern radios implement some form of CAT but
almost every radio implementation is different. The functions controlled by the computer depend on the
particular application and radio.
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
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 Radio
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 to support the
automatic switching functions
the "none" options in the Radio box.
