1. SERVICE

1.1. Device service

EM-481 provides data collection from connected MODBUS devices, data transfer to the server, data access
(via MODBUS TCP or SMS text messages), event tracking and response to events (sending SMS notifications,
recording values to MODBUS devices).
EM-481 provides:
 Flexible options of connection (via wire or wireless communication GSM or UMTS , automatic method
selection of communicating with a server, automatic or manual selection of GSM provider and communication
