Red Lion G3RS - Manual (Page 3)

CONFIGURING A G3RS OPTION CARD
The G3RS 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 G3RS 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 G3RS 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.
CABLES AND DRIVERS
Red Lion has a wide range of cables and drivers for use with many different
communication types. A list of these drivers and cables along with pin outs is
available from www.redlion.net/g3. New cables and drivers are added on a
regular basis. If making your own cable, refer to the “G3RS Port Pin Outs” for
wiring information.
RS232 PORTS
The G3RS option card has one RS232 port. The port can be used for either
master or slave protocols with any G3 configuration. The RS232 port and
RS422/485 port on the G3RS option card are multiplexed because they share the
same hardware. Both ports can be used with master protocols. However, when the
RS232 port is used with a slave protocol, the RS422/485 port is not available.
For examples of RS232 communications refer to your G3 operator interface
literature.
RS422/485 COMMS PORT
The G3RS option card has one RS422/485 port. This port can be configured
to act as either RS422 or RS485.
The RS422/485 port and RS232 port are multiplexed because they share the
same hardware. Both ports can be used with master protocols. However, when the
RS422/485 port is used with a slave protocol, the RS232 port is not available.
Note: All Red Lion devices connect A to A and B to B, except for Paradigm
devices. Refer to www.redlion.net for additional information.
For examples of RS422/485 communications refer to your G3 operator interface
literature.
DH485 COMMUNICATIONS
The G3RS option card’s RS422/485 port can also be used for Allen Bradley
DH485 communications. When this port is configured to communicate DH485,
the RS232 port can not be used because the ports share the same hardware and the
G3RS option card multiplexes the ports to communicate via two protocols.
WARNING: DO NOT use a standard DH485 cable to connect this port to Allen
Bradley equipment doing so may cause irreparable damage to the equipment
connected. A cable and wiring diagram are available from Red Lion.
