Preventing Electrostatic Discharge
The Multi-Vendor Interface module is sensitive to electrostatic
discharge.
ATTENTION
!
This module is sensitive to electrostatic discharge.
Electrostatic discharge can damage integrated
circuits or semiconductors if you touch backplane
connector pins. Follow these guidelines when you
handle the module:
•Touch a grounded object to discharge static
potential.
•Wear an approved wrist-strap grounding device.
•Do not touch the backplane connector or
connector pins.
•Do not touch circuit components inside the
module.
•If available, use a static-safe work station.
•When not in use, keep the module in its
static-shield bag.

Prepare the Chassis for Module Installation
Before you install the MVI module, you must install and connect a
ControlLogix chassis (1756-A4, 1756-A7, 1756-A10, or 1756-A13) and
power supply (1756-PA72 or 1756-PB72). To install these products,
refer to publications 1756-5.1 and 1756-5.2.

Set the Configuration Jumpers
Before installing the 1756-MVI module in the chassis, set the
module’s configuration jumpers on the module’s printed circuit
board.
1. The module ships with the Setup jumper in the Setup position
(see the figure on the following page). The Setup jumper
causes the module to boot with console port PRT1 enabled at
19200 baud, no parity, 8 data bits and 1 stop bit.
Note: When the Setup jumper is removed, the module will
boot with the configuration set in the BIOS Setup Menu. This
configuration is described in detail in the Quick Start section
of this manual. See “Configure the Manual” on page 16.
2. To enable communications on Port 2 and Port 3, place a
jumper in the RS232, RS422, or RS485 position for each port.
The module ships with the jumpers in the RS232 position
(default).

You can install the module in any slot in the ControlLogix chassis.
You can also install multiple MVI modules in the same chassis. The
figure below shows chassis slot numbering in a 4-slot chassis. Slot 0
is the first slot and is always the leftmost slot in the rack (the first
slot to the right of the power supply).

Remove or Replace the Module (when applicable)
IMPORTANT If you are replacing an existing module with an
identical one, and you want to resume identical
system operation, you must install the new module
in the same slot.
Push on upper and lower module
tabs to disengage them.

Publication 1756-IN001A-US-P - May 2000
Installing or Removing the Module While Power Is Applied
You can install or remove the module while chassis power is
applied.
Install the Serial Adapter Cables
Three identical serial adapter cables are supplied. Each cable has a
locking-type RJ45 plug on one end and a DB-9 male connector on
the other end. Insert the RJ45 connector on each cable into the RJ45
receptacles marked PRT1, PRT2, and PRT3 on the module.
ATTENTION
!
When you insert or remove a module while
backplane power is on, an electrical arc may occur.
An electrical arc can cause personal injury or
property damage by:
•sending an erroneous signal to your system’s
actuators causing unintended machine motion or
loss of process control.
•causing an explosion in a hazardous
environment.
Repeated electrical arcing causes excessive wear to
contacts on both the module and its mating
connector. Worn contacts may create electrical
resistance that can affect module operation.
To install the locking-type RJ45
connector, slide the plug into
the receptacle. The locking
mechanism prevents the cable
from being removed during
normal operation. To remove
the cable, press the locking tab
and remove the plug.

Perform a Quick Start
This section provides a quick overview of the steps necessary to
configure the 1756-MVI module.
Note that this information is not meant to be
comprehensive. For more detail, refer to the 1756-MVI
Programming Reference Manual, publication
1756-RM004A-EN-P.
Connect the Console
1. Place the Setup jumper in the setup position as described on
page 7.
2. Connect a terminal using terminal communication software
(e.g., Hyperterminal) to the MVI module’s console port, PRT1.
This is an RS232 DTE port, which requires a null-modem cable
to connect to a PC serial port.
3. Configure the console terminal for 19200 baud, 8 bits, 1 stop
bit, no parity. Configure the terminal emulation mode as ANSI
or VT100.
4. Turn on the power to the MVI module. The MVI module
includes an embedded BIOS and DOS-compatible operating
system. The boot messages should appear on the console. If
no messages are seen, check to be sure the Setup jumper is
installed and that the cable connections are correct.
Configure the Module
The embedded BIOS initializes the module and allows you to
configure the module using the BIOS Setup Menu.
1. To enter the Setup Menu, press Ctrl-C on the console
terminal when prompted. (If the module has already booted,
type “reboot” at the prompt.)

Note that if “Console on Port 1” is Enabled and “Console Baud
Rate” is 19200 baud, the module acts the same as if the Setup
jumper is in place.
5. If a Compact Flash card has been installed, change the
“Compact Flash” setting to Enabled. The Compact Flash card
will act as drive C:\.
6. Press Esc to exit the Setup Menu.
Test the Module
The module should boot to the DOS command prompt, A>. Type
“dir” to display the contents of the ROM disk.
IMPORTANT The configuration set with the MVI Module
Configuration Menu is enabled only when the
Setup jumper is not installed. If the Setup
jumper is installed, the MVI console port is
configured at 19200 baud, no parity, 8 data bits,
and 1 stop bit.
