• - All run time functionality
• - May be compressed to fit in flash if so, it
  takes 20 secs to decompress

31

• Assign an IP
• Install and Setup Host Software
• Set onboard settings (not necessary with
  NativeCOM)
• Cabling

32
Assigning An IP Address

• NativeCOM (demo)

Cabling

• Electrical Interfaces
• RS232
• DCE (Data Communication Equip) - modems
• DTE (Data Termination Equipment) - terminals,
  printers, etc
• (basically everything except a modem)
• DCE is designed to plug straight into a DTE
• To connect a DTE to a DTE, need a null modem
• Our devices are DTE (termination) devices

43
Cabling

• Electrical Interfaces
• RS422 and RS485
• Electrically the same
• RS422 is point to point - usually 4 wire
• RS485 allows a bus - usually 2 wire
• Must be terminated at the receive end
• Termination is external, except on NPS/1000
• A bias is provided to put the bus in a known
  state if no device is driving it.

44
Cables

• Modem Signals (supported only under RS232)
• DCD - Data Carrier Detect - detect device or
  connection
• RTS/CTS - Ready/Clear To Send - flow control
• DTR/DSR - Data Terminal/Set Ready - flow control
• RI - Ring Indicator - call indication
• DCD is significant to us
• By default on RCS, DCD must be present to start
  service on a port
• By default on RCS, loss of DCD hangs up service
  on port
• Can be disabled by telling unit to ignore DCD
• This mode can be enabled on other products

45
Cables
Most Peripherals are DTE devices so need a Null
Modem

Debug and Diagnostics - LEDs

• Status LED
• Rapid Orange blink during self test
• 1/2 second Orange blink waiting for BOOTP/DHCP
  (RCS)
• 1 second Orange blink decompressing OS (RCS)
• Solid Green - initializing OS (RCS)
• Solid Green - waiting for BOOTP/DHCP (NPS or NDS)
• Blinking Green - Ready!
• Red - failed self test - blinks error code
• 92 memory failure
• 99 network failure
• Port LEDs (serial, WAN, printer)
• Orange/Dark when port is closed
• Green when port is open
• Blinking Green when data flows
• Flashes Red momentarily on error

51
Debug and Diagnostics

• LAN/Hub/Switch LEDs
• Orange when not connected
• Green when valid connection to a switch or other
  device
• Blinking Green when data flows
• Red on error
