{Purpose and scope of use}
The Neusoft controller and the master station (PDA or computer) together constitute the active transmission equipment of the remote centralized meter reading system (AMR), which realizes the carrier communication function of the master station, using low-voltage power lines as the communication medium and terminal equipment (carrier electric energy meter) 1) Establish a reliable data connection, and perform copy control operations on the terminal equipment in a half-duplex communication mode.
Mainly used in the on-site installation and commissioning of Neusoft's collection system.
{Function}
★Setting parameters: the handheld computer forwards the control instructions through the controller, and sets and modifies the parameters of the electric meter module through the power line.
★Reading parameters: It has the ability to specify the data of one meter and continuously read the meter number, meter base number, range, pulse constant, and current pulse number of the meter in batches.
★Monitoring single table: real-time monitoring of single table is possible.
{Feature}
★Reliable data transmission.
★Strong anti-interference ability .
★Small and easy to carry.
★It is necessary equipment to realize field maintenance.
