• 1.58" x 5.54" x 5.12" (4.01 cm x 14.10 cm x 13.00 cm)
• 1 RU (rack unit) high
• 300 mA @ 12 VDC
See the NI-900 On-Board Memory Specifications section on page 9.
• 304 MIPS
• 1.30 lbs (0.59 kg)
• Metal with black matte finish
• FCC Part 15 Class B, CE, and IEC 60950
• RS-232 DB9 connector (male) can be connected to a DB9 port on a
computer. This port can be used with both Serial and NetLinx programming
commands. It is also used to both upload and download information from
the NetLinx Studio 2.4 program.
• Sets the communication parameters for the Program port.
• Red LED lights to when IR data is being received via the rear IR RX port.
• Three red LEDs light during the transmission of IR or Serial data via the rear
IR port.
• Four yellow LEDs light when the rear I/O channels 1 - 4 are active. LED
indicator for each I/O port reflects the state of that particular port.
• One set of red and yellow LEDs light when the rear DB9 Port (1) transmits or
receives RS-232, 422, or 485 data:
- TX LED (red) lights when transmitting data
- RX LED (yellow) lights when receiving data
- LED activity reflects transmission and reception activity
• These LEDs do not reflect changes in either the RTS or CTS when
hardware handshaking is used.
• Green LED lights when the Ethernet cable is connected and an active link is
established. This LED also blinks when receiving Ethernet data packets.
• Green LED lights when the Controller is programmed and communicating
properly.
• Red LED lights when the Controller transmits data, sets channels On/Off,
sends data strings, etc.
• Yellow LED lights when the Controller receives data from button pushes,
strings, commands, channel levels, etc.
Provides the NetLinx ID (D:S) assignment for the device.
• The D notation is used to represent a device number.
• The S notation is used to represent the System number of the Master.
• Refer to the NetLinx Integrated Controller WebConsole & Programming
Guide for details.
• RS-232/422/485 control port uses a DB9 (male) connector with
XON/XOFF (transmit On/transmit Off), CTS/RTS (clear to send/ready to
send), and 300 - 115,200 baud.
• Channel range = 1 - 255
• Channels 1 - 254 provide feedback
• Channel 255 (CTS Push channel): Reflects the state of the CTS Input if a
'CTSPSH' command was sent to the port
• Output data format for each port is selected via software
• A single DB9 connector provides RS-232/422/485 termination
