SHOCK/ENERGY HAZARD
Install in Restricted Access Location.
Use 10-14 AWG copper wire only.
Terminal block screw torque: 9 in-lbs (1 nM).
Branch circuit must have circuit breaker, 15A or less.
Install terminal block cover after wiring.
Connect Serial I/O to Host Computer
Using the standard null-modem DB9F-to-DB9F cable provided, connect one end to the FDC3300
connector labeled RS-232 and the other end to an available DB9M RS-232 connector on your host
computer. The factory default serial port parameters are 19200 baud, 8 data bits, no parity and 1 stop
bit. The FDC3300 does not use hardware or software handshaking, so make sure that your terminal
program is configured appropriately and disable all handshaking.
Connect Signal Inputs and Outputs
Using coaxial cables, connect your analog signal(s) to the Signal Input A and/or Signal Input B on
the FDC3300. The factory default for the FDC3300
switchmode
setting is for Signal Input A to be
the primary and Signal Input B to be the secondary. You can change this by using the
switchmode
command over the Serial I/O Port.
Connect coaxial cables from each of the FDC3300 signal outputs to your equipment.
Connect Disable Inputs (External Alarm Inputs)
If the source(s) of your reference signal(s) has (have) compatible TTL alarm output(s) that you would
like to use to force signal input switching on your FDC3300, connect these using coaxial cables to the
Disable A and/or Disable B input(s) on the FDC3300. The factory default for the FDC3300
dis-
ablemode
setting is to ignore these inputs. If you plan to use them, you will need to use the
dis-
ablemode
command over the serial I/O port to configure them.
Connect Alarm Output
If you are using the FDC3300 summary alarm output, connect a coaxial cable from the equipment
that will be monitoring the FDC3300 to the Alarm output on the FDC3300.
