Pulse Counter - Honeywell Cloud Link 4G Modem User Manual

4.3 Pulse Counter

Cloud Link 4G Modem supports 1-channel pulse-counting input up to 10 pulses per second with a min-
imum pulse width of 25 mS; It is to provide additional redundancy on the UMB pulse input front end. A
pulse input from the UMB is wired to this additional pulse input. The EVC will read the pulse counter
information recorded in the Cloud Link 4G Modem using AT commands and compare it with its own pulse
accumulation register and raise alarm if any mismatch in accumulation. Pull-up resistor in Cloud Link
4G Modem can drive ~30uA of wetting current.
The pulse counter in Cloud Link 4G Modem is not MID/MC certified, cannot be used for billing.
