Push Button Switches:
The Crosspoint Switch may be controlled using Normally Open Momentary push button
switches. Use one switch for each output channel that needs to be controlled. One pin of
the switch connects to a source of 28V (+16 to +30 Volts), the other pin is wired to the 20
pin connector on the cross point switch. A short press of the switch commands its
corresponding output channel to be connected to the next enabled input channel. Input
channels 1 and 2 are always enabled. Input channels 3 and 4 can be individually
enabled by connecting pins 11 and 12 (for channels 3 and 4 respectively) to a source of
28V (+16 to +30 Volts). For instance: : If pins 11 and 12 are left disconnected, then
inputs 1 and 2 are enabled, and inputs 3 & 4 are disabled. A short press of any of the
channel command switches will cycle their corresponding output through inputs 1, 2, 1, 2,
1, 2….. If pin 11 is connected to a source of 28V and pin 12 is left disconnected, then
inputs 1,2,& 3 are enabled, and input 4 is disabled. A short press of a channel command
switch will cycle its corresponding output through input 1, 2, 3, 1, 2, 3, 1, 2…..
Notes:
Industry standard M17/94-RG179 Coaxial Cable with many brands of SMB Mini
connectors that are specified for use with RG-179 @ 1.5GHz or more will support up to
100 feet of length between the cross point switch and either a signal source, or a monitor
or other endpoint. Premium Cable such as Thermax 875-892 cable and their specified
connectors can increase useable cable length.
