Serial Control• Control Protocols
– RS422, RS485, RS232– Standard ASCII Text Strings
• PASHA, X-Net AND RATC2• Control Alias
– 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
