Description
Power A/B LEDs These red/green LEDs indicate power input status. Green means the
power supply is good. Red means the power supply is installed but has
failed. Off means the optional power supply is not installed. Power
Supply B is on standby when both supplies are good.
Input A/B LEDs These red/green/yellow LEDs indicate the signal input status. For a
full description see
Appendix A - LED Indicators
.
Output 1-10 LEDs These red/green/yellow LEDs indicate the presence or absence of
signals at the output connectors. Green means the output is present and
red means the output is absent or shorted.
Alarm LED This red/green/yellow LED indicates the presence of a fault condition.
Green means there is no alarm condition. Red means an alarm condi-

RS-232 Connector This DB-9M connector provides the RS-232 serial I/O interface to the
FDC3302. This allows the user to initialize, monitor and control the
FDC3302. See
Chapter 3 - RS-232 Serial I/O Port Signal Definitions
for detailed information.
10/100Base-T Jack This optional RJ-45 connector mates with the ethernet twisted pair
cable from the network.
Signal Input A/B Jacks These two BNC connectors accept the A and B analog signal inputs.
Disable Input A/B Jacks These two BNC connectors accept the A and B logic level external
alarm inputs. If properly configured (see
disablemode
), a high level
on this input will disable the corresponding Signal Input.
Alarm Output Jack This BNC connector provides the open-collector alarm output. This
output is asserted during the power-on/startup sequence and when an
alarm condition exists.
