Setting the ALARM DIP (Switch Bank S3)
The third switch bank is used to set the user-configurable alarm feature that indicates the
loss of a data signal. When enabled, the continuous loss of data for more than 1 second will
be sensed and trigger this alarm. This feature will not operate properly in cases where logic
0 or no data bits last for more than 1 second.
To enable or disable the alarm function on the 5018 model, set the ALARM DIP switch as
follows
Transmit Data Signal Position 1:
ON = enable
OFF = disable
Receive Data Signal Position 2:
ON = enable
OFF = disable
Optical Fiber Types Supported
Versions of the universal data transceiver are available to drive most multimode (MM) and
single-mode (SM) optical fibers. The specific models are identified by a suffix at the end of
the model numbers as follows:
Fiber Size
Connector
850nm
1300nm
50µ, 62.5µ MM
ST
-1
-3
8/10µ SM
FCPC
N/A
-7
A 6300 adapter is available to allow the -1 and -3 versions of the 5018A model to be used
with multimode fiber and SMA connectors. A 6310 adapter is available to allow
the -7 versions of these models to be used with single-mode fiber and single-mode
ST connectors.
Indicator LEDs
The 5018A model has three green signal indicator LEDs that continuously monitor
operation. One, labeled “Power (or PWR)”, lights when operating power is present. The
other two, labeled “Transmit (or Tx)” and “Receive (or Rx)”, turn on whenever the
transmitted or received data is in the “high” state and off when it is in the “low” state.
As a result, they actually blink at the rate of the operating data. However, most data rates
are so fast that these LEDs will usually appear to be on continuously.
The 5018A also has a red LED labeled “ALRM” which lights when an alarm condition
is present.
