Hello this is what I bought the DATALM from B&B Electronics to alert
maintenance to downed communications. Know when you've got incoming
data. Simply place the Data Alarm in the data line you want to monitor.

It has DB25 female and male connectors with all 25 lines passing
straight through so it can easily be added to any existing system. It
can be set to detect data or absence of data on TD or RD on RS-232
communication lines, or the strobe on parallel communications. When the

alarm condition is met, an LED turns on and a relay is tripped. Three
Relay Terminals are provided - Common, Normally Closed or Normally Open

positions. An audio alarm can be enabled to sound at the same time. The

relay and alarm can be set to sound for a minimum period of time
ranging from 1 second to indefinitely. A reset button is used to turn
off the alarm.
Measuring only 1.32"H x 2.40"W x 4.60"L, it fits easily next to your
computer or printer. Requires 11 to 16 VDC at 80 mA. Power supply not
included. Recommended Power Supply: 232PS 120VAC/60Hz to 12VDC @ 100mA,

2.5 mm plug, (+) Tip (UL/CSA approved).
