The M1592A Serial Network Interface Module (Serial NIM) is designed specifically to allow serial access to a wide range of third party serial devices in either point-to-point or multi-drop configuration using RS485.

The Serial NIM comes equipped with the Conet/s protocol for peer-to-peer applications, or with Modbus Master and Slave protocols for access to a wide range of third party devices.

In addition, the Serial NIM supports the development of custom protocol drivers in the EziFORTH programming language. Custom protocols maybe downloaded to the module to communicate with any device equipped with a RS232 or RS485 serial port.

All data is accessible by a SCADA, DCS or PLC via the Maxiflex system CPU through a 4000 register Data Interchange Table.

All system configuration data and dynamic data can be read and written through this convenient table interface.

Using the supplied Omniset configuration utility, advanced polling schemes may be easily set up without the need for programming. All polling and communications processing is performed in the module, unloading the Maxiflex CPU module for the more important system tasks such as control and SCADA communications.

Through the use of network routing capability built into the Conet/s protocol, this NIM may form part of a larger network of networks, passing data seamlessly across different network segments transparently to the supervisory computer.

The M1592A is the recommended replacement for the M1585A is in all new installations. The M1592A is functionally identical to the M1585A except that the DB9 serial connector pin out has been changed to the revised Omniflex standard pin out that requires no internal link selection when choosing RS232 or RS485
