B&B Electronics VFG9000-SERIAL - Quick Start Guide - Manual (Page 3)

POWER SUPPLY REQUIREMENTS
NEW AND EXISTING INSTALLATIONS
The VFG9000-SERIAL option card draws all of its power from the main
board of the Fieldbus Gateway. The specifications of the Fieldbus Gateway
account for the power needs of an option card.
COMMUNICATING WITH THE VFG9000-SERIAL
OPTION CARD
CONFIGURING A VFG9000-SERIAL OPTION CARD
The VFG9000-SERIAL is configured using Fieldbus Gateway Manager
software. The software is available as a free download or it can be ordered on
CD. By configuring the VFG9000-SERIAL using the latest version of the
software, you are assured that your unit has the most up-to-date feature set. The
software can configure the VFG9000-SERIAL through the RS232 PGM port,
USB port, Ethernet port, or CompactFlash socket on your Fieldbus Gateway.
Additional information can be found in your Fieldbus Gateway hardware
bulletin and the Fieldbus gateway Manager user manual.
CABLES AND DRIVERS
B&B 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.bb-elec.com. If making your own cable, refer to the
“VFG9000-SERIAL Port Pin Outs” for wiring information.
RS232 PORTS
The VFG9000-SERIAL option card has one RS232 port. The port can be
used for either master or slave protocols with any Fieldbus Gateway
configuration. The RS232 port and RS422/485 port on the VFG9000-SERIAL
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 Fieldbus Gateway literature.
RS422/485 COMMS PORT
The VFG9000-SERIAL 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.
For examples of RS422/485 communications refer to your Fieldbus Gateway
literature.
DH485 COMMUNICATIONS
The VFG9000-SERIAL 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 VFG9000-SERIAL 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 B&B.
