1. STANDARD EATURES
The SW2X1, Electronic A / B switch has 2 buffered inputs and one
buffered output for easy interfacing. There are no mechanical multi-pole
switches to wear out or fail.
Front panel control and remote control provide flexible operation to fit
your specific application.
Quickly and easily switch from primary system to backup system at the
press of a button.
In the event of power failure, on-board bypass relays switches “A” input to
output.
2. INSTALLATION SW2X1-GPI
a. Chose whether the GPI will be self powered or have power supplied by
the source equipment. Each GPI is independently settable.
JUMPERS: J1 – J8 Revision 8/16/ 7
DRY: External circuit powers
INPUT opto-isolator
INPUT is isolated from other inputs
Place jumper over pins 2 and 3
WET: SW2X1 powers INPUT opto-
isolator
External circuit provides path to
ground
Place jumper over pins 1 and 2

b. Connect primary GPO source to the A input connector, use male D9
cable connector.
c. connect secondary GPO source to the B input connector, use male D9
cable connector.
d. Connect the destination GPI connections to the Output connector.
e. Connect the power supply’s connector (9-pin female D) into the
housing’s POWER connector (male 9-pin D). The PWR LED on front
panel will light. Power supply is +5VDC. 2A.
f. NOTE: The Power-up state defaults to input A and its status indicator
will light.
Installation is complete.

4. INSTALLATION SW2X1-RS422
a. Connect one end of an RS422 cable (9-pin D-type, male to male, 1 to 1)
into the rear panel connector (9-pin D-type) labeled INPUT A. Connect
the other end to an RS422 serial source (controller #1).
b. Connect a second RS422 serial source (controller #2) in the same
manner to INPUT B.
c. Connect an RS422 serially controlled VTR, (using an RS422, 9-pin D-
type male to male cable) into the 9-pin female connector labeled
OUTPUT.
d. Connect the power supply’s connector (9-pin female D) into the
housing’s POWER connector (male 9-pin D). The PWR LED on front
panel will light. Power supply is +5VDC. 2A.
e. NOTE: The Power-up state defaults to input A and its status indicator
will light.
Installation is complete.

6. MODE SELECTION SW2X1-GPI
The SW2X1-GPI supports two modes of operation.
a. MODE 1
Remote and local control is possible.
Active A input or A switch = Select A input.
Active B input or B switch = Select B input.
This is the default mode. The jumper is installed
over pins 3 and 4 on header J11 on the PCB.
The mode of operation is determined ONLY at
POWER UP. Changing the jumper after power up
will have no effect. Power MUST be turned off then
on to change the SW2X1’s MODE.
Jumper Diagram for Mode 1.
b. MODE 2
Remote control ONLY is possible. Local control is
disabled.
The LOCKOUT LED is turned on.
Remote B input inactive = Select A input.
Remote B input active = Select B input.
The jumper is installed over pins 1 and 2 on
header J11 on the PCB.
The mode of operation is determined ONLY at
POWER UP. Changing the jumper after power up
will have no effect. Power MUST be turned off
then on to change the SW2X1’s MODE.
