NXC-ME260 NetLinx Master-Ethernet Card/Module
Specifications
NXM-ME260 Specifications
Power consumption 750 mA @ 12 VDC
Memory • Compact Flash: 16 MB standard (upgradeable)
• Volatile: 16 MB
• Non-volatile: 1 MB
Microprocessor Coldfire 5407 (32-bit )
Front Panel Components:
Program port DB-9 (male) connector that supports RS-232 communications to your PC for
system programming and diagnostics. You set the port's communication speed
with the Baud Rate DIP switch. See the Setting the Program Port DIP
Switch section on page 7 for details.
There are Program ports located on the front and rear panels of the Master
Card for easy access. Because these ports share the same circuitry, you
should never use both at the same time; doing so will result in communication
and/or programming errors.
Status LED Green LED blinks to indicate that the system is programmed and communicat-
ing properly.
Output LED Red LED blinks when the Master Card transmits data, sets channels on and
off, sends data strings, etc.
Input LED Yellow LED blinks when the Master Card receives data from button pushes,
strings, commands, channel levels, etc.
Front Panel LEDs -
blink patterns
These LEDs also display special blink patterns when a mode is activated. See
the Modes and front panel LED blink patterns section on page 4 for details.
Program Port DIP Switch 8-position DIP switch located behind the front panel for setting the baud rate for
the Program port. The baud rate settings are 9600, 38,400 (default), 57,600
and 115,200 (bps). See the Setting the Program Port DIP Switch section on
page 7 for details.
Rear Panel Components:
PWR connector 2-pin (male) green captive-wire connector for 12 VDC power supply.
EXPANSION OUT port RJ11 connector connects to an AXB-SPE Server Port Expander.
Ethernet 10/100 port RJ-45 Ethernet 10/100 connector. The Ethernet Port automatically negotiates
the connection speed (10 Mbps or 100 Mbps) and whether to use half duplex
or full duplex mode.
Ethernet 10/100 LEDs LEDs that show communication activity, connections, speeds, and mode infor-
mation:
• A-activity - Yellow LED blinks when receiving Ethernet data packets.
• L-link - Green LED lights when the Ethernet cables are connected and
terminated correctly.
• SPEED - Green LED lights when transmitting data at 100 Mbps, and is off
when transmitting at 10 Mbps.
• FD-full duplex - Green LED lights when running in full duplex mode, and is off
when running half duplex mode.
AXlink connector Black 4-pin (male) captive-wire connector that provides data and power to
external control devices.
• Power rating = 6 A max; actual load depends on connected power supply.
Axlink Status LED Green LED blinks to show AXlink and expansion port data activity.
PROGRAM port 5-pin (male) gray connector for system programming and diagnostics. There is
a Program port located on the front and rear of the Master Cards for easy
access. Because these ports share the same circuitry, you should never use
both ports at the same time. Doing so will result in communication and/or pro-
gramming errors.
