1 General
Neutron15 is a remote pulse logger designed for collecting and reporting
pulses from varying kinds of consumption meters with a pulse output,
e.g. electricity, gas, heat or water meters. Pulses are stored locally and
can be fetched by a Modbus master device via an RS485 connection.
Default Modbus ID is 45. It can be changed with the Special Command.

ranty does not cover dismantling, installation, and introduction costs and
the like. ionSign warrants that the provided software essentially manage
with their designed tasks, at the time of delivery. All significant software
defects are covered by the warranty. The defects will be resolved without

the defect. If the delivery includes third party products or services, these
are only covered by the applicable warranty provided by that third party.
