We offer protocol converter. Main features: this is microcontroller based unit. the unit continuously receives data on rs-232 serial port in ascii format. as per pre-defined logic, converts this data and organize as a list of registers. set of data stored in these temporary registers can be accessed using modbus protocol thro rs-485 port or tcp/ip port. unit ip address is programmable. user can also configure serial interface settings (data rate, parity etc.) other features: operating voltage: 24 vdc +/- 20% din rail mount enclosure led indication for power status and communication activities enclosure: abs material colour: grey mechanical dimensions: 55 (w) x 75 (h) x 109.5 (d) mm mounting: rail mounting or wall mounting
