The simple commands used for selecting the channels are
CHANNEL DECIMAL ASCI I
CHANNEL1 1! 31, 21
CHANNEL 2 2! 32, 21
: : :
CHANNEL 9 9! 39, 21
CHANNEL10 a! 61,21
CHANNEL11 b! 62,21
: : :
CHANNEL16 g! 67,21
Communication parameters are 9600 baud, no parity, 8-bit and
1 stop bit.
Whenever any channel is selected there well be a feedback from
the switcher on RS232 port i.e. when channel 1 is selected,
switcher will send 1! on the serial port pin no. 2. Similarly 2!
for channel 2 and so on.
B. SCAN MODE (OPTIONAL)
For scanning mode, keep slide-switch in scan position.
Scanning time for each channel is 5 seconds.
Scan mode operates in two ways: -
Scanning for the activated PCs or laptops only : -
In this mode, scanning will be done for activated PCs
only.

Scanning of all the PCs or laptops regardless of the
activated PCs:-
Page 6
Short all the pins of D9 pin connector (using another D9
Female Connector i.e.1 to 9 pins) at the rear panel. In
this mode scanning of all PCs is done regardless of the
PCs are ON or OFF.
C. AUTO MODE
For Auto mode, keep slide-switch in Auto position.
Auto mode works on priority basis. First priority is given to
Channel 1, 2nd priority to channel 2 and so on.
For example if Sync signal is detected on channel 2 and
channel 3 simultaneously, only channel 2 will get selected
on priority basis. Channel 3 can be selected only when
channel 1 and channel 2 are deactivated.
