What devices can interface to LV to report elapsed time?

[cwest]

I have an application where I would like to log the elapsed run time of
several devices. I cannot find any hour meters that have a serial I/O or other
means to read them out. This would seem to be a common task. Does anyone have
any suggestions for a timing module with remote readout?

are just a couple timers with RS-232 options.

An alternative would be to activate a switch or relay when the device is on, connect the relay (debounce or use solid state) to a digital input of a DAQ card, and write a LV program to time how long inputs have been activated. You may want to log data to disk every so often in case of PC crash or loss of power.

Unclear as to your remote readout needs.
