6.3 Scan Mode

The VSM-802 now features a Scan Mode whereby each output can
independently cycle through all 8 inputs at a customer specified period.

To enter the Scan Mode for a given output, press keys 9 and 10 at the
same time on the corresponding keypad. To enter the scan mode from a
serial device type: O1S or O2S which forces output 1 or 2 into scan
mode respectively (“ “denotes Enter).

To Exit Scan Mode, just press any key on the keypad. This will cause
the output to switch to selected channel and quit scanning. This can
also be done from a serial device by issuing a valid switch command
such as: O2I5 (see Addendum on page 13 of the manual for details
regarding controlling the switch through a serial device (or Windows®
HyperTerminal™)

When you place an output into scan mode, the Model 802 will
remember and remain in that state even after power off. So if you
disconnect power and reconnect power, it will pick up and start
scanning where it left off. In fact you don’t even need a keypad
plugged in for that output once power is restored!

Scan mode is not available in Tandem or Dual Head Switching mode
(see Addendum on page 14 of the manual for details regarding “Dual-
Head Switching”.
