Dataforth's MAQ20-COM2 communication module communicates using Ethernet, USB and RS-232 industrial buses with the host software interfacing to the system using the Modbus TCP or RTU protocol. The Ethernet interface allows for up to four simultaneous socket connections which can support up to four simultaneous Modbus TCP transactions. Baud rates as fast as 921.6kbps can be run over RS-232 serial communication.
Data acquired via the MAQ20-COM2 data acquisition & control system can be stored for later analysis. Each communication module has an easily accessible and removable 4GB micro-SD memory card that can be used to log data from all input modules supported via the MAQ20.
To power the MAQ20 data acquisition & control system, a 7-34V DC power source is connected to the MAQ20-COM2 communication module. Regulated and protected supplies housed within the module provide power both to the internal circuits and to all modules in the system.
