nfiguring the B3000-B
Using the B3000-B
The B3000-B mistic serial brain is a drop-in replacement for the
obsolete B3000 serial brain. The B3000-B can be used with:
•
FactoryFloor controllers running OptoControl strategies
• SNAP PAC S-series controllers, along with other mistic I/O units
migrated to PAC Project
• A PC equipped with an Opto 22 PCI-AC48 adapter card (which
provides an RS-485 port)
NOTE: The B3000-B has the same functionality as the B3000, except
that it
does not support the Optomux protocol . For Optomux, use an
E1 or E2 brain. If you are not migrating to the SNAP PAC System but
building a new system, use SNAP PAC SB serial brains instead.
For Help
This technical note covers basic configuration only.

Setting Up Serial Networking
1. Attach an RS-485 serial cable to the serial port. If you are using
mistic interrupts, wire IRQ+ and IRQ– (pins 6 and 7). See the
B3000-B User’s Guide for details on network wiring.
2. Rotate the baud rate switch to set the
desired baud rate, as shown in the
table below.
NOTE: Due to timing tolerances, some
baud rates may not work with some
compatible devices.
3. Use the three termination switches to
set termination as follows:
• For the B3000-B at the physical end of
the cable, set all three of the termina-
tion switches to the ON position.
• For all B3000-B units that are not at the
physical end of the cable, set all three of
the termination switches to the OFF
position.
NOTE: Since biasing is normally done at
the controller or computer, the B3000-B
does not include biasing switches.
4. Use the two rotary address switches to
set the unit’s address, as shown on the
following page.
