Switches are ON when pushed to the right (as viewed from the back of the
panel). All Baud Rates are 8 Bit, No Parity, One Stop Bit.
The switches are read by the microprocessor only at power-up; for switch
configuration changes to take effect, cycle the power input to the RS8x8HB.
In the non-verbose mode, only the word DONE will be reported. In either
mode, an incorrect or meaningless command will cause the word ERROR to be
reported.
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 RS8X8HB.
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 RS8x8HB.
In the verbose mode, each time a routing command is sent, the current routing
map will be reported on the RS232 line.

2.8 DISABLING THE TIMED SEQUENCE MODE
To avoid accidentally enabling the timed sequence mode, turn switch 4 ON.
This will disable the timed mode.
2.9 DISABLING BREAKAWAY AUDIO
To disable breakaway audio feature, turn switch 5 ON.
2.10 VERTICAL INTERVAL SWITCHING
All units are now fitted with the vertical switching option. Switching will occur
during the vertical interval, referencing the sync signal on input number one. If
input number one has no input, switching will be random with respect to sync.
Note: vertical interval switching has no meaning unless the inputs are synchronous
to one another.
