Specifications

TIP: If the application permits, always configure the Radio Control port to use two stop bits.

Communication is a little bit slower (9%) but more reliable.

Data flowing through the Control channel is indicated by two arrows. A green arrow shows data flow from

the host application to the radio and a red arrow shows data flow from the radio to the application.

TIP: If the application provides PTT (T/R) 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. In

addition, MK2R cannot properly handle T/R sequencing or protect the Power Amplifier and

LNA from hot switching since the radio must be keyed before MK2R can sense it.

Note: The virtual COM port assigned for radio control in Router can be shared with CW, PTT and/or

foot switch (use same virtual COM port), but sharing is not recommended unless it is specifically

supported by the application. Many applications use the control lines (RTS, CTS, DTR, DSR) for

handshaking or apply a fixed level.

In order for Router to automatically control Audio Switching and PTT keying, it must know what radio model

is connected to MK2R. To configure the radio, click the Set button for each radio.

Select your radio in the Radio

combo box. Then select the

communication speed in the Baud

rate box. Note: The baud rate must

match that of your radio. All Icom

and some Ten-Tec radios require

setting the appropriate CI-V address

(use the information from Setup

hints window). If everything is

configured properly, your radio’s

current operating frequency and

mode should be displayed.

Configure your radio parameters as

described in the Setup hints

window. These parameters are

different for each radio and can be

set in radio menu. Check your

transceiver manual for information

on configuring your radio.

The special VOICE/DIGITAL combo

box is used to automatically switch

Router and MK2R/MK2R+ between

VOICE and DIGITAL (AFSK/PSK)

operation.

TIP: Disable the auto baud function in any Icom Radio used with MK2R. Configure the radio,

Router, and your application software to operate at 9600 baud.
