1.  The SNAP-SCM-232 and SNAP-SCM-485-422 serial communication modules are part of the SNAP PAC System. They conveniently provide two channels of serial data at a remote Ethernet location.

2.  The SNAP-SCM-W2 serial communication module provides two isolated channels of data input from attached devices that comply with the Wiegand® interface format.

3.  The SNAP-SCM-PROFI module is a high-speed serial communications module that provides a standard electrical interface between Opto 22’s Ethernet-based SNAP PAC System and PROFIBUS DP® networks.

4.  The easy-to-use SNAP PAC Motion Control Subsystem provides an integrated hardware and software toolset for controlling multi-axis stepper motors.
