• Control Protocols
Serial Control
– RS422, RS485, RS232
– Standard ASCII Text Strings
• PASHA, X-Net
• Control Alias
AND
RATC2
– Replaces Control Groups
– Improved User Interface
– Supports Long Alias Names
• Case Sensitive
• No Spaces Allowed
PASHA And X-Net Still Use Three Character Alias
Nion Serial Control
Port
•DB9 on the rear of the unit.
•Unique pinout - be careful.
•RS422/485 operation.
•Integral 120 ohm terminators.
•Use pins 1 & 2 for RS485 (1+, 2-).
•Supplies +12VDC @ 500mA
for XControls.
Control Via TCP/IP
• RATC And RATC2
–Both Supported
–Re-Use Existing Control Systems
–RATC Type Must Be Selected
During Design (NioNode Properties)
–RATC2 - Improved User Interface
• Shorter Commands
• Type “h” For Command List
RATC2 Telnet Session
Control Via TCP/IP

at PowerPoint all day?
Let’s DO something!
Even if it’s wrong.
