INSTALLATION

This section offers step-by-step instructions for installing IN3600 Series switchers.
1.

Connect all sources to the input connectors. Unused inputs do not need to be terminated.

An interface may be required for each computer video signal source in order to split off a signal for
each local monitor, bring all signals into the appropriate format, and amplify the signal to
compensate for long input/output cable runs.

Connect the IN3600 Series switcher output to the display device.

Apply AC power to the unit.

It is very important that all input / output connections be made utilizing high resolution coaxial cables.
Proper cable selection is critical to overall system performance, especially when working with high
frequency signals and/or long cable runs. The IN7000, IN7200 or IN7300 Series cables (available with
4 or 5 BNC connectors) or IN8000 Series VGA extension cables are recommended for best results.

OPERATION

Power Switch
The POWER switch is located on the back of the unit. When power is turned on, the unit will default to
Input 1 and the Input 1 LED will light to indicate that the unit is active. When powering up several units
that are linked together in a Master/Slave arrangement, it is required that either all units be powered on
simultaneously or that the Master unit be powered on last. This is to allow the Master unit to poll all
Slave units to determine how many are used in a multiple unit system.

Modes of Operation
The IN3600 Series switchers provide various modes of operation. These modes include:

♦

Manual Mode

In the Manual Mode, inputs from a single or multiple set of units are accessed by pressing the
corresponding front panel switch for that input. In this mode, RGB delay and Vertical Interval Switching
can be enabled. (See Programming Options)

♦

Scan Mode

In the Scan Mode, the unit switches between inputs at a specified time period. The time period is
programmable in 2.5 second increments up to 37.5 seconds. When the Blank button is used, all scanning
stops and individual inputs can be selected and viewed. When Blank is depressed again, scanning will
resume at the input it last left off at. In this mode, RGB delay and Vertical Interval Switching are
disabled.

♦

Autoswitching Mode

In the Autoswitching Mode, all inputs are scanned for active signals. The highest number input with an
active signal is switched to the output. (i.e. If inputs 2,3 and 4 have active inputs, input 4 will be switched
to the ouput.)

In all modes, the following options are available:

♦

Blank = nothing or sync

♦

Front Panel = enabled or disabled

♦

RS232 communication baud rates of 1200, 2400, 4800 or 9600
