Switches are ON when pushed up. All Baud Rates are 8 Bit, No Parity, One or

Two Stop Bits. The switches are read by the microprocessor only at power-up; for
switch configuration changes to take effect, cycle the power input to the RS4x4HB.

2.7 ANSWERBACK MODES

The user may choose between two modes of answerback: verbose and non-

verbose. Select the mode using position 3 of the programming switch located on
the rear panel of the RS4X4HB.

Position 3 ON is verbose, while position 3 OFF is non-verbose.
The switches are read by the microprocessor only at power-up; for switch

configuration changes to take effect, cycle the power input to the RS4x4HB.

In the verbose mode, each time a routing command is sent, the current routing

map will be reported on the RS232 line.
