In addition to SNMP, Davicom has chosen the MODBUS protocol as a means of adding more I/O capability to its remote site management systems. Both the MEXM-1 and MEXM-2 Expansion Modules use this protocol, in either the RTU or TCP modes, to talk with Davicom units. Opting for this means of expansion also opened the door to directly interfacing with external MODBUS-capable equipment such as Power Generators, HVAC units, GPIO modules and thousands of other devices.

How to Connect the ACPM-1 Modbus Device to the Cortex
DEX Knowledge Base Article
Given the fact that Cortex units have a MODBUS interface as well as an SNMP Manager and SNMP Agent, they can be used as translators to allow SNMP Management Systems to read information from MODBUS devices and also to allow MODBUS slave devices to be controlled by SNMP readings from external SNMP Agents.
