2.1.1 Basic operations
The basic operations include selecting the MU-2-R to use, setting the interface, selecting the mode and function
window and so on.
The MU-2-R has 3 operation modes (command, text, and binary).
The transmission test function and air monitor function operate in the command mode. The buttons for these
functions are disabled in modes other than the command mode.
Immediately after opening the COM port and when returning from the air monitoring function to the control and
test window, the program automatically reads and resets the channel and Equipment ID, and these items are
displayed on the control and test window screen. If you perform an unexpected operation, the Equipment ID
may change to ‘FFh’, therefore always check the Equipment ID.
(1) Always close the COM port before connecting the MU-2-R, changing the equipment, turning the power on and
off and so on. If not, not only will the program shut down due to a COM port error, there may be adverse effects
to the operation of the OS.
(2) In the binary mode, characters entered in the input line of the control and test window are sent to the MU-2-R as
they are input.
(3) In order to return from the text mode to the command mode, the program sends the 1-byte ESC code:1Bh.
(4) An RS232C signal DTR line is used for switching between the binary mode, text mode, and command mode.
(5) When carrying out the various tests, check the User ID, Group ID, Equipment ID, Destination ID, transmission
channel and the routing information in the control and test window. In particular, note that when finishing on the
air monitoring function screen, the Equipment ID may be ‘FFh’ unless the power of the MU-2-R is turned off.
