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.

3. CERTIFICATIONS AND COMPLIANCES:
Refer to main unit manual or “Agency Approvals” section of B&B

Electronics’ website for agency certifications.

ISOLATING

DC : DC

A

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
