1. Do not turn off power to the unit while this light is flickering. The unit writes
data in two minute intervals. Later Microsoft operating systems will not lock
the drive unless they need to write data; Windows 98 may lock the drive any
time it is mounted, thereby interfering with logging. Refer to “Mounting the
CompactFlash” in the Crimson 2.0 User Manual.

ETHERNET COMMUNICATIONS
Ethernet communications can be established at either 10 BASE-T or 100
BASE-TX. The Master’s RJ45 jack is wired as a NIC (Network Interface Card).
For example, when wiring to a hub or switch use a straight-through cable, but
when connecting to another NIC use a crossover cable.
The Crimson 2.0 manual contains additional information on Ethernet
communications.
RS232 PORTS
The Master has two RS232 ports. There is the RS232/PG port and the
COMMS port. Although only one of these ports can be used for programming,
both ports can be used for communications with a PLC. The RS232/PG port can
be used for either master or slave protocols.
RS422/485 PORT
The Master has one RS422/485 port. This port can be configured to act as
either RS422 or RS485.
Note: All Red Lion devices connect A to A and B to B, except for Paradigm
devices. Refer to
Red Lion website
for additional information.
DH485 COMMUNICATIONS
The Master’s RS422/485 COMMS port can also be used for Allen Bradley
DH485 communications.
WARNING
: DO NOT use a standard DH485 cable to connect this port to Allen
Bradley equipment. A cable and wiring diagram are available from Red Lion.
