Select the “Serial CTS” radio button in the Carrier Detect frame. Configure the “Serial Port”
dropdown list for the port used for EchoLink. Confirm the correct serial port to use by examining
your computer configuration; the correct port depends on your particular computer.
If MCP-2A is installed, usually this software uses the same port as EchoLink software. When
there is only one COM port on a computer, it is usually COM1. If a USB-serial conversion cable is
being used, the correct COM port number may be COM2 or larger.
Do not check the Invert Sense check box for the TM-D710A/E and TM-V71A/E transceivers. This
is to set the Output Logic of Squelch Control from the transceiver to “Active High”. Refer to Step 3
of Parameter Settings in Section 8.5.4 Using MCP-2A to Configure TM-D710A/E. It is not
necessary to check the Squelch Crash Anti-Trip check box either. Next, click the TX Ctrl tab.

Transmit checkbox. Next, click the DTMF tab.
