RS232 PORTS
The Data Stationr 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 Data Station 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. Refer to www.redlion.net
for additional information.
DH485 COMMUNICATIONS
The DSPZR’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.

NOTE
For reliable operation of this and other Red Lion products, one of the
following brands of CompactFlash card must be used...
SimpleTech SMART ® Modular swissbit ®
SanDisk ® Silicon Systems
Not all of the above manufacturers offer CompactFlash cards recognized to
UL standards, which may be required for your application.
Although RLC products limit use of CompactFlash card memory to 2 GB,
cards with a larger capacity can be used. They MUST be formatted to 2
GB and use the FAT 16 file system. It is recommended to format the CF
card using the format utility from within Crimson.
