The CR-IPS4 IP to Serial Controller is a Control System Centre for users to control a variety of serial devices. This four way version supports RS-232 at each I/O port and 1 port for the additional use of RS-422 or RS-485. Users can connect up to four devices simultaneously and control them via a 3 (or 5)-pin adapter cable to send RS-232/422/485 commands from this unit.

Comprehensive user control interfaces are available, including WebGUI, Telnet, and console (RS-232 in).

The CR-IPS4 IP to Serial Controller operates using either a 12V/1.25A adapter or Power over Ethernet (PoE). PoE allows users to power the unit directly from a standard PoE network switch without an external power adapter, providing greater installation flexibility.

The LEDs on the board provide status indicators for users to check: power and Ethernet status. It supports IEEE 802.1x RTS/CTS protocol to avoid hidden stations. The unit also provides a hotkey for convenient firmware updates.
