ALWAYS Use A Flyback Diode On A Relay Coil! It
Prevents Back EMF From Destroying The Switching
Transistor.

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

13
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 _at_ 500mA
• for XControls.

14
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

• SNMP Functions (Currently not factory supported)
• Offload Control Duties From NIONs
• Control Third Party Products (Currently not
  factory supported)
