b SoftPAC cannot communicate through serial ports on the PC.
c Serial ports are software configurable for RS-232 or RS-485.
d PAC firmware >=R9.4b, 8 max connections. Lower firmware, 2 max connections.
f Available with OptoOPCServer and PAC Control, through a SNAP PAC controller.
g SoftPAC includes Status Read, Status Write, and Scratch Pad memory map areas.
hModels manufactured before August 2007 and S1s with serial numbers 625653 and lower have user-replacable backup batteries. See original user's guide.
i Flash memory function implemented via a file; size is limited only by disc space
k PAC firmware 9.4a and loader 6.1a or higher. S-series with microSD & manufacture date older than 06/2014 supports maximum 2 GB microSD.
l Units with serial numbers lower than 500,000 have an 8-24VDC input voltage rating. Verify voltage on the unit's faceplate before applying power.
n For compatibility with legacy Opto 22 hardware, see Form 1693, Legacy and Current SNAP Product Comparison and Compatibility Charts.
m I/O features vary by model. For details, see form 1677, SNAP PAC Controller and Brain Comparison Chart.
o SNAP-PAC-R1s with serial numbers lower than 600,000 and all SNAP-PAC-R1-Bs; limited to 4-point digital modules per rack.
p Not supported: serial, motion control, Profibus, & Wiegand modules.
q Four-channel modules only; not high-density modules.
r Requires a SNAP-IDC5Q quadrature input module.
s Requires a SNAP analog TPO module (SNAP-AOD-29).
