Contact Closure Devices
Any device capable of providing a latching contact closure may be used to control the IN3552R /
IN3562R. Several contact closure type control devices are available:
IN6901 / IN6902 RS-232 to Contact Closure Converters - allow IN3500 Series switchers and
other INLINE devices with contact closure control ports to be controlled by RS-232 sources such
as control systems and computer serial ports.
Control System - many control systems are capable of providing contact closures.
Remote Control Panel - a custom remote panel or remote switch may be fabricated by the
installer.
Disable Front Panel Input Selector
The front panel input selector can be disabled for applications where the switcher will only be controlled
through the remote port. To disable or enable the front panel input selector, set Jumper 7 (located inside
the unit) as follows:
J7 Open:
Front Panel Input Selector Enabled (factory default)
J7 Closed: Front Panel Input Selector Disabled
When the front panel selector is disabled, the remote port always functions in the following manner (it
makes no difference how the front panel selector is set):
Pins 1 and 2 open:
Input 2 Selected
Pin 1 grounded to Pin 2: Input 1 Selected
MONITOR EMULATION (IN3562R ONLY)
Some computer graphics cards must be connected to a local monitor in order to output a signal or select
an appropriate resolution. In order to ensure proper initialization of the graphics card at computer boot
up, a local monitor should be connected to each computer. If that is not practical, then the IN3562R
monitor emulation dip switches (located on the bottom of the switcher) should be set to the appropriate
settings for each input as indicated in the chart below.
Monitor Emulation Input 1 Input 2
VGA Color Monitor Dipswitch 1 - On Dipswitch 4 - On
Apple 13/14" RGB Monitor Dipswitch 1 - On Dipswitch 4 - On
Apple 2-Page Mono Dipswitch 3 - On Dipswitch 6 - On
Apple Portrait Monitor Dipswitch 2 & 3 - On Dipswitch 5 & 6 - On
Apple 21s Color Monitor Dipswitch 1, 2 & 3 - On Dipswitch 4, 5 & 6 - On
When using a multiscan or other MAC monitor not shown in the chart with most newer Apple Macintosh
computers, the Apple 13"/14" RGB monitor emulation settings will initialize the video card. The desired
resolution may then be selected using the Chooser menu.
In order to set Jumper 7, the IN3552R / IN3562R case must be opened. The procedure
for opening the case and location of jumper 7 are indicated on page 6. This procedure
should only be done by a qualified technician in a static-free environment. Failure to
follow proper procedures could result in damage to the unit or electric shock.
