RS232/485 SERIAL OPTION CARD FOR VLINX FIELDBUS GATEWAY
CONFIGURED USING VLINX FIELDBUS GATEWAY MANAGER
ISOLATED RS232 AND RS485 MULTIPLEXED PORTS CAPABLE
OF COMMUNICATING WITH RS232, RS422, RS485 AND DH485
DEVICES AT UP TO 115,200 BAUD
EASY INSTALLATION
VFG9000-SERIAL-1012qsg
GENERAL DESCRIPTION
The Vlinx Fieldbus Gateway contains a proprietary expansion port which
provides a high speed, parallel architecture that extends the functionality and
flexibility of the platform. This approach allows these products to evolve
concurrently with the latest advances in communications and standards, without
sacrificing performance. This high bandwidth channel has significantly greater
throughput when compared to the traditional (external) serial gateway approach.
The VFG9000-SERIAL option card adds an additional RS232 and RS422/485
port to the series. This isolated card protects user equipment from potentially
harmful ground loops while providing high-speed RS232, RS422, RS485, and
DH485 communication options to the end user.
The VFG9000-SERIAL communication card is easily installed by removing
the blank expansion port cover of your Fieldbus Gateway, and plugging the
VFG9000-SERIAL card into the expansion port. Configuration is simple using
B&B Electronics’ free Fieldbus Gateway Manager software.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
literature or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use the controller to directly command motors, valves, or other
actuators not equipped with safeguards. To do so can be potentially harmful to
persons or equipment in the event of a fault to the controller.
CAUTION: Risk of Danger.
Read complete instructions prior to
installation and operation of the unit.
SPECIFICATIONS
1. POWER REQUIREMENTS: 24 V @ 50 mA max. Power is supplied to the
option card from the main board of the Fieldbus Gateway.
2. COMMUNICATIONS:
Serial Ports: Format and Baud Rates for each port are individually software
programmable up to 115,200 baud and are isolated to help prevent ground
loops. The RS422/485 and DH485 port via RJ45 and the RS232 port via
RJ12 share the same hardware. The VFG9000-SERIAL option card
multiplexes the ports to communicate via two protocols. These ports may be
used to configure different master protocols, but only one port may be used
if configuring a slave protocol or AB DH485.
DH485 TXEN: Transmit enable; open collector, V
Isolation from VFG9000-SERIAL Communication ports to the Fieldbus
Gateway: 1000 VDC for 1 minute.

Ideally, handle the cards at a static controlled clean workstation.
Also, handle the cards by the edges only. Dirt, oil, or other
contaminants that may contact the cards can adversely affect circuit
operation.
Warning: Risk of Danger: Be sure to remove all power before
removing the expansion port cover.

INSTALLING THE VFG9000-SERIAL OPTION CARD
1. Remove power from the unit
2. Insert a flat-bladed screwdriver into the slot at the top of the expansion port
cover. Gently apply pressure on the screwdriver in an upward direction until
the expansion port cover disengages from the unit as shown in Figure 1.
3. Verify that the option card knobs are in the “unlocked” position as shown in
Figure 2.
4. Carefully insert the option card into the expansion port opening while
aligning the card-edge connector on the option card with the main board's
header, as shown in Figure 3. Once aligned, gently press on the front of the
card until it is flush with the front of the case.
5. Turn the option card knobs to the locked position as shown in Figure 4.
WARNING - EXPLOSION HAZARD - DO NOT DISCONNECT

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.
WARNING - EXPLOSION HAZARD - DO NOT DISCONNECT
WHILE CIRCUIT IS ALIVE UNLESS AREA IS KNOW TO BE
NON-HAZARDOUS.
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.
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.
