CONFIGURING A G3CN OPTION CARD
The G3CN is configured using Crimson software. Crimson is available as a free
download from www.redlion.net/g3, or it can be ordered on CD. Updates to
Crimson for new features and drivers are posted on the website as they become
available. By configuring the G3CN using the latest version of Crimson, you are
assured that your unit has the most up-to-date feature set. Crimson software can
configure the G3CN through the RS232 PGM port, USB port, Ethernet port or
CompactFlash socket on your G3 operator interface. Additional information can
be found in your G3 hardware bulletin and the Crimson user manual.
CANopen PORT PROTOCOLS
The G3CN option card has one CANopen port. This port may be configured
for various CANopen protocols. Check www.redlion.net/g3 for currently
supported protocols.
TERMINATION RESISTOR
An onboard termination resistor is selectable through a jumper setting. The
termination resistor is rated for 124Ω at 1W. If a different termination resistance
is desired, choose the jumper setting for no termination resistor. At this point you
will be required to connect your own termination resistor between positions 2
and 4 of the five position connector.
CAN GND
Position 1 of the pluggable connector provides a CAN ground connection.
This terminal is isolated from the HMI unit.
CAN-
Position 2 of the pluggable connector provides the CAN- bus line (active
low). This terminal is isolated from the HMI unit.
SHLD (OPTIONAL CAN SHIELD)
Position 3 of the pluggable connector is provided for optional shield
connections. This position is available only to tie shield wires together or to earth
ground. There is no internal connection to earth ground. The SHLD position is not
connected to any circuitry internal to the G3CN option card or G3 HMI unit.
CAN+
Position 4 of the pluggable connector provides the CAN+ bus line (active
high). This terminal is isolated from the HMI unit.
V+ (OPTIONAL 24 VDC)
Position 5 of the pluggable connector is provided for optional 24 VDC
connections. This position is available only to tie 24 VDC wires together. The
G3CN card neither provides 24 VDC power nor uses 24 VDC power through
this connection. The V+ position is not connected to any circuitry internal to the
G3CN option card or G3 HMI unit.
