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. CR’s Tuner Helper 3, a free Windows application, can connect to the IP-232
for point-and-click Ethernet tuner control and setup.
• Extends RS-232 control over Ethernet
• Controls up to nine CR 232-series tuners (up to 9 can be daisy-chained from RS-232 port)
• Powers from Ethernet (PoE) in A and B modes
• Integrates any RS-232 controlled device, including video projectors, displays,
• Works with CR’s free Tuner Helper 3 software for graphic Ethernet tuner control for CR tuners
• Operates with Telnet commands from AMX, Crestron, Simtrol, other control systems, and PC
software
• Sets up from IP, RS-232 port, and onboard DIP switches
• Mounts in RK3 AV System Tool Rackmount or alongside AV tuner in RK-1 or RK-HD1 rack mounts.
• Includes power supply
• Meets RoHS safety and California energy standards

Installation
Installation is a simple and direct process:
1. Set IP address information locally via RS-232
2. Set RS-232 COM port baud rate and data parameters locally via RS-232 or remotely over IP
DIP Switch Settings
Use the DIP switch on the bottom of the unit for setup (turn IP-232 so switches are on the bottom of the case,
S1 is on the left, Up turns switches ON):

*Values in gray cells are the default settings.
• Command - Turn Switch 7 ON changes RS-232 from operation as a remote RS-232 port to receiving
setup commands via a Terminal program, turn off to return to remote RS-232 mode.
• Default RS-232 - Turn Switch 8 ON to operate RS-232 port at 9600 baud, no parity, 8 data bits, 1
stop bit, no handshaking. Switch to OFF to return to current settings.
• Default Settings – Turn S1 Switches 1-4 OFF, 5-8 ON, then all S2 switches ON, then reset power.

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.
Set Up IP-232 RS-232 via Control System
Once you’ve defined the IP address of the IP-232, you can also use your control system to configure the RS232 port. The typical approach is to send configuration commands via Telnet port 23 in the system start-up
sequence. With this approach, the programmer can define RS-232 port attributes in software, long before
the actual installation.

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.
General protocol specifications
Characters in command strings to the IP-232 are common ASCII keyboard characters.
Command strings sent to the IP-232 begin with the ASCII > (greater than symbol) as an 'Attention'
character and end with carriage return - ASCII CR, Hex $0D, or keyboard Enter - as an 'End-of-command'
character.
Responses from the IP-232 begin with the ASCII < (less than symbol) as an 'Attention' character and end
with a carriage return followed by line feed an ASCII LF or Hex $0A as 'End-of-command' characters.
A carriage return is required at the end of each command and is assumed in all examples.
Command String Structure
[Attention] (Unit#) [Command] (Parameters) [Return]
Attention Single character (>) starts the string
Unit# The Unit# is expressed as an ASCII 0-9 when used in multiple tuner applications.
To address all units, use a Unit # of 0 (Zero)
No unit number will default to Unit#1
Command A two-character command
Parameters Added attributes to some commands
Return A carriage return ends the command string, you may use ASCII CR, Hex $0D, or keyboard
‘Enter’ in programming. For simplicity, the programming examples in the manual will not
show the ‘CR’ – so remember, you’ll need to add it in your control code.
Command and Status Response
Commands can be sent back to back at any time without any delay. To allow for rapid, multiple commands,
status responses are intentionally delayed by about 125mS, sending the most current status in response to
control commands or user actions.
