The E1 is for digital I/O and the E2 for analog I/O.  We designed the E1 and E2 as drop-in replacements for older serial-based B1 and B2 brain boards.  [Read More](https://blog.opto22.com/optoblog/optonews-e1e2-firmware-release) 0 Comments [Click here to read/write comments](https://blog.opto22.com/optoblog/optonews-e1e2-firmware-release#comments-listing) Topics: [optonews](https://blog.opto22.com/optoblog/topic/optonews), [Migration](https://blog.opto22.com/optoblog/topic/migration), [I/O](https://blog.opto22.com/optoblog/topic/io), [Optomux](https://blog.opto22.com/optoblog/topic/optomux), [OptoNews 2015-10-21](https://blog.opto22.com/optoblog/topic/optonews-2015-10-21) ## [OptoNews: Troubleshooting resources for the SNAP PAC System](https://blog.opto22.com/optoblog/optonews-troubleshooting-resources-snap-pac-system) Posted by [Jean Femia](https://blog.opto22.com/optoblog/author/jean-femia) on Oct 21, 2015, 5:18:09 PM - [Tweet](https://twitter.com/share) [![](https://blog.opto22.com/hubfs/Products/snappacsystem_224x180.png)](https://blog.opto22.com/optoblog/optonews-troubleshooting-resources-snap-pac-system) Opto 22 products are known for their reliability.
