The compact SNAP-PAC-S2 has four serial ports, each of which is fully configurable for either RS-232 or RS-485 serial communication, making it ideal for connecting to machines, devices, instrumentation, I/O subsystems, and other equipment with serial interfaces–including weigh scales, vibration monitors, RFID and barcode readers, display terminals, and printers. An RS-232 Point-to-Point Protocol (PPP) modem connection for communication over leased lines, radios, and cellular networks is also supported.

In addition to its four configurable serial ports, the SNAP-PAC-S2 also features two 10/100 Mbps Ethernet interfaces for host and I/O communication over Ethernet networks. These two independent interfaces can be used to create dual Ethernet networks for segmenting I/O and host traffic, or to design redundant Ethernet links for critical applications.

Other SNAP-PAC-S2 features include a 32-bit multitasking processor with floating point unit, 32 MB of RAM, 16 MB of flash memory, and 8 MB of battery-backed RAM. The controller supports multiple communication protocols, including TCP/IP, SNMP, FTP, Modbus®/TCP and OptoMMP™, and free developer toolkits add support for Data Highway, Modbus ASCII, and Modbus RTU. The controller is capable of multitasking up to 32 PAC Control flowcharts simultaneously.
