Overview The IP-232 extends Ethernet control to CR’s 232-series TV tuners, video projectors, displays, and other RS232 controlled equipment. The IP-232 is PoE compliant, accepting power through the LAN in either A or B modes. The unit is fully programmable, and includes switch settings to aid in installation. A single IP-232 can control up to nine tuners over Ethernet, with a full 2-way data connection to custom control systems or PC software.
Specifications Physical RS-232 Ethernet Setup Power POE DIP Switches Includes Options Size: 5.5” [140mm] wide x 1.1” [28mm] height x 3.
Installation Installation is a simple and direct process: 1. 2.
Set Attributes via RS-232 Commands Use a standard Null Modem DB9 F to DB9 F cable to connect a PC or USB COM port. Refer to RS-232 Commands in this manual for using Terminal to set up the IP-232 for your application. Set RS-232 Attributes via Web Page You can also set the RS-232 properties from an onboard Web page. Just set your browser to the unit’s IP address and click to set.
RS-232/IP Control Protocol Overview The IP-232’s full duplex RS-232 and Telnet protocol enables a system programmer to set up RS-232 port operation and IP addressing. All commands are sent as ASCII strings. No delays between characters or commands are required, as data is interrupt driven and buffered. The same RS-232 protocol can be sent over IP, sent to Telnet port 2728. All settings are saved to NVRAM in the IP-232.
RS-232 Commands Code Function Operation Defines IP Operation Ethernet IP - Use “>” symbol before each command - End with carriage return to send IP returns the current MAC address, Ethernet firmware version, current IP address, subnet mask, and gateway. Response example (S or D at end of IP signifies DHCP or Static address): IP Address $MAC=0014C8000201 $IP=192.168.001.232S IG=000.000.000.000 IM=255.255.255.
