‘Two-in, two-out’ mode connections
In this mode, the primary and secondary remote receiver modules are connected
differently. For the primary receiver, use the connection details shown on the
previous page. For the secondary receiver, connect the module as shown here:
The switch settings should be set for normal operation. Generally this means all
set to OFF, however:
• Switches 2 and 3 can be altered to select the required hot keys, and
• Switch 4 selects Automatic (OFF) or Manual (ON) video compensation mode.
For details, please refer to the user guide for the X-Series Extenders.
Operation
Power and activity indicator
On the front panel of the Dual Video
Transmitter a small recessed indicator provides
confirmation of power and activity, as follows:
• Constant red - power applied, no
communication activity.
• Flickering red - power applied,
communication occurring.
• Slow flashing red - module is in flash
upgrade mode.
‘Two-in, two-out’ mode
In this mode, operation should be straightforward with the main video image
appearing on the monitor connected to the primary receiver. The keyboard and
mouse connected at the primary receiver will have total control over the system.
The output from the computer’s second video controller should then appear on
the monitor connected to the secondary receiver. If there is no image on the
secondary monitor, first check that the computer is actually generating a second
screen image.
‘One-in, two-out’ mode
In this mode, control of the computer is arbitrated on a first come, first served
basis. In the standby state, control is available to both receivers and their
keyboard indicators both show their current Num Lock, Caps Lock and Scroll
Lock conditions.
At the moment that a key
is pressed or a mouse is
moved on one receiver, the
other receiver is temporarily
locked out (the video image
remains). The keyboard
indicators on the locked out
system then begin to flash to
confirm its status:
After two seconds of
inactivity from the receiver
that currently has control,
the system returns to its standby condition and the keyboard indicators of the
locked out system return to their ‘natural’ state.
