• OptoDataLink (PAC Project Professional only) transparently provides multiple connections for
data exchange with popular databases such as Microsoft SQL Server, Microsoft Access, and
MySQL. OptoDataLink connects your SNAP PAC System with the tools used for making business
decisions, bringing realtime, accurate data to decision makers.
• PAC Manager is a utility application for assigning IP addresses to SNAP PAC controllers and
brains, reading or changing basic controller configuration, upgrading firmware, and inspecting
or testing controllers and I/O.
Software Availability
PAC Project Basic is included with SNAP PAC controllers and can also be freely download from the
Opto 22 website. www.opto22.com. PAC Project Professional is available for purchase. You can also
separately purchase PAC Control Professional, PAC Display Professional, OptoOPCServer, and
OptoDataLink as needed. For additional information, see the
PAC Project Data Sheet , Opto 22

Architectural Diagrams
Because SNAP PAC S-series controllers have multiple Ethernet and serial interfaces, these controllers
are suitable for use in a variety of system layouts and architectures.
Dual independent Ethernet interfaces, for example, let you configure a network for link redundancy
or segmented networking. A PPP serial interface provides a dial-up modem link for remotely located
control systems, while two-wire RS-485 support integrates existing Opto 22
mistic serial-based I/O
units into contemporary Ethernet-based systems.
On Wired+Wireless models, the additional wireless LAN interface offers even more flexibility in
system design.
