Features
Description
Opto 22 B1 (digital) and B2 (analog) Optomux® brain boards are
intelligent digital processors that operate as slave devices to a
host computer. Each brain board contains a microprocessor that
provides the necessary intelligence to communicate with a host
computer and also perform control functions at each channel of
IO.
The B1 and B2 brain boards are designed to mount on most
Opto 22 IO mounting racks that have header connectors. IO
mounting racks that accept single-channel standard and G4 IO
modules, Quad Pak™ IO modules, or SNAP IO™ modules—and
racks that have built-in integrated IO circuitry—are all available.

Networking
Classic Brain Boards
Intelligent digital processors.
Serial data link operates at selectable baud rates from
300 baud to 38.4 Kbaud
Optomux units can be configured for either multidrop
or repeat mode operation.
B1s and B2s communicate with a host computer via an RS-422/
485 serial link using twisted-pair cable that connects to each
Optomux unit (brain board plus rack). The serial data link operates
at selectable baud rates from 300 baud to 38.4 Kbaud.
Optomux units can be configured for either multidrop or repeat
mode operation. In multidrop mode, up to 32 Optomux units can
be networked over a total line length of up to 5,000 feet.
Additional units can be added by using a repeater. In repeat
mode operation, up to 256 Optomux units can be networked
with up to 5,000 feet between units.
To use Optomux I/O on an Ethernet network, use Opto 22’s E1 or
E2 brain boards. These boards can use both serial and Ethernet
networks simultaneously, and are drop-in replacements for B1s
and B2s. See the E1 and E2 data sheet (Opto 22 form 1546) for
information.

Classic Brain Boards
Installation and Wiring
Power Requirements
Classic Brain Boards
The B1 and B2 brain boards require +5 volts DC (± 0.1 VDC)
at 0.5 amps.
Although it is possible to distribute DC from a common power
supply to several locations, better noise immunity is obtained by
having separate power supplies at each physical location where a
rack/brain board unit is installed. The +5 VDC power supply is
connected to the I/O mounting rack beneath the removable
brain board portion of the digital Optomux unit.
Analog racks also require +15 VDC and -15 VDC (± 0.25 VDC) to
power the analog I/O modules. The amount of power required
depends on the type and number of analog I/O modules that are
plugged into the Optomux unit. See the data sheets for your
modules; power requirements for each module are included in
the module specifications.
Analog racks also provide terminals for a separate +24 volt supply
that can be used for powering a 4–20 mA current loop using 4–
20 mA analog I/O modules. For this type of application, the +24
volt supply is required in addition to the supplies mentioned
above. Refer to the module’s data sheet for information on wiring
4–20 mA modules with a loop supply.
The current requirements given for the output modules are only
for the modules. To determine what size power supply is needed,
add the load requirements for each module to determine total
power supply requirements.
NOTE: Use only isolated supplies with Optomux products. Isolated
supplies reduce the risk of ground loops in the communication
wiring. Do not connect the power supply’s DC common to earth
ground. Linear power supplies are recommended.
Connecting the Power Supply
The diagram below shows how to connect the power supply.
Connect 5-volt power to the barrier strip connectors marked “+
5V” and “GND” on the mounting rack. If the + 5-volt supply is
used by more than one unit or by other devices, make sure the
voltage at each rack is 5 VDC (± 0.1 V).
The +5-volt and ±15-volt wires should be routed away from any
high-voltage field wires. There should only be one “earth” ground
connection per network, typically at the host site. If the ground
connection is at the host site, make sure none of the power
supplies is grounded. This method prevents ground loop
problems due to offset voltages appearing between multiple
ground points.
If an Opto 22 PBSA/B/C power supply is used with the digital
racks, the + 5 VDC logic connection is made by the supply when
it is screwed to the rack. In this case, the only connection required

is the 120 VAC (220 VAC or 10–28 VDC depending on supply type)
connection to the PBSA (or PBSB or PBSC) supply.
Separate or combined + 5 VDC (± 0.1 VDC) and ± 15 VDC (± 0.25
VDC) supplies can be used to provide power to analog racks.
When using a multiple-output supply, make sure that the 5 VDC
RETURN line is separate from the 15-volt COMMON line.
Otherwise, the analog modules will not be isolated.
Use a consistent color code from the power supply to all brain
boards to prevent wiring errors. Size 18 AWG or larger is
recommended for power supply wiring.
The high cost of electrical wiring and the susceptibility of analog
signals to noise make it desirable to place the brain board as close
as possible to the controlled device.
The default communication mode for the B1 and B2 brain boards
is multidrop. When wiring a multidrop communications cable,
keep in mind that the cable is a high-speed data-transmission
line. To reduce reflections, make sure the line is terminated
properly at both ends and that all stubs are less than three inches
long.
Repeat mode is a jumper-selectable option. In this configuration,
each brain board acts as a repeater, allowing up to 5,000 feet
between units. Since a power failure at any unit breaks the
communications link, battery backup is recommended. Note that
you cannot mix units operating in repeat mode and units
operating in multidrop mode on the same network.

CAUTION: Check polarities of all power supply connections before
applying power. Incorrect polarity will damage the brain board
and I/O modules.
Use a consistent color code from the power supply to all brain
boards to prevent wiring errors. Size 18 AWG or larger is
recommended for power supply wiring.
The B1 or B2 brain board plugs into the mounting rack using the
50-pin connector. The figures below show how to install the brain

secured for maximum physical strength. Be sure to leave sufficient
space between adjacent units for the I/O wiring.
Installing I/O Modules
CAUTION! Be sure that all power to unit and to the controlled
devices is removed before installing or removing I/O modules.
Input and output modules can be installed in any rack position.
For specifications and wiring information on modules, see the
module’s data sheet.
Communication Cables
DATA SHEET
Form 463-130722
The following cables are recommended for RS-485/422 serial
communications. Although you may elect to use other cables,
keep in mind that low capacitance (less than 15 pF/ft.) is
important for high-speed digital communication links. The cables
listed below are all 24-gauge, 7x32 stranded, with 100-ohm
nominal impedance and a capacitance of 12.5 pF/ft.

Wiring Diagrams
A complete connection at each brain board consists of 10 wires:
two twisted pairs and a common coming from the computer or
previous brain board, and two twisted pairs and a common going
to the next brain board.
The following illustration shows standard and alternate wiring
diagrams. It also shows jumper settings for repeat and multidrop
modes and for proper termination and biasing. When wiring a
series of Optomux units, always think of the previous Optomux
unit as the host.
To ensure reliable communications, we recommend the
following:
• Use shielded twisted-pair wires for the communications
wiring. (See recommended cables on this page.)
• Route the communication and DC power wiring separately
from any high-voltage field wiring or AC power wiring.

Specifications: Jumpers
DATA SHEET
Jumpers in Group A (shown on the previous page) route wiring
for repeat or multidrop mode communications and also provide
proper termination and biasing. All brain boards on the same
network must operate in the same mode. Jumper settings for
Group A are shown with the wiring diagrams on page 7.
Jumpers in Group B set the address and baud rate and also
determine the message protocol. See the following page for
address jumper settings.
Group B Jumpers
Select the baud rate using jumpers 8, 9, and 11 in Group B,
according to the diagram below. All units on the same network
should be set for the same baud rate.
The message protocol can be set as 2-pass or 4-pass. Use 2-pass
for normal operation. The 4-pass protocol may be useful during
troubleshooting, because it allows the host to examine and
display the command message the brain board received before
the command is executed. See the diagram below for jumper
settings on message protocol.

SNAP PAC System
Designed to simplify the typically complex
process of selecting and applying an
automation system, the SNAP PAC
System consists of four integrated
components:
• SNAP PAC controllers
• PAC Project™ Software Suite
• SNAP PAC brains
• SNAP I/O™
SNAP PAC Controllers
Programmable automation controllers
(PACs) are multifunctional, modular controllers based on
open standards.
Opto 22 has been manufacturing PACs for over two
decades. The standalone SNAP PAC S-series, the rack-mounted
SNAP PAC R-series, and the software-based SoftPAC™ all
handle a wide range of digital, analog, and serial functions for
data collection, remote monitoring, process control, and
discrete and hybrid manufacturing.
SNAP PACs are based on open Ethernet and Internet Protocol
(IP) standards, so you can build or extend a system easily,
without the expense and limitations of proprietary networks
and protocols. Wired+Wireless™ models are also available.
PAC Project Software Suite
Opto 22’s PAC Project Software Suite provides full-featured,
cost-effective control programming, HMI (human machine
interface) development and runtime, OPC server, and
database connectivity software for your SNAP PAC System.
Control programming includes both easy-to-learn flowcharts
and optional scripting. Commands are in plain English;
variables and I/O point names are fully descriptive.
PAC Project Basic offers control and HMI tools and is free for
download on our website, www.opto22.com. PAC Project
Professional, available for separate purchase, adds one
SoftPAC, OptoOPCServer, OptoDataLink, options for controller
redundancy or segmented networking, and support for legacy
Opto 22 serial mistic™ I/O units.
SNAP PAC Brains
While SNAP PAC controllers provide central control and data
distribution, SNAP PAC brains provide distributed intelligence
for I/O processing and communications. Brains offer analog,
digital, and serial functions, including thermocouple
linearization; PID loop control; and optional high-speed digital
counting (up to 20 kHz), quadrature counting, TPO, and pulse
generation and measurement.
SNAP I/O
I/O provides the local connection to sensors and equipment.
Opto 22 SNAP I/O offers 1 to 32 points of reliable I/O per
module, depending on the type of module and your needs.
Analog, digital, and serial modules are all
mixed on the same mounting rack and
controlled by the same processor (SNAP
PAC brain or rack-mounted controller).
Quality
Founded in 1974, Opto 22 has established a
worldwide reputation for high-quality
products. All are made in the U.S.A. at our
manufacturing facility in Temecula,
