The Second Launch Pad Count Down system is implemented using VXI hardware designed by Data Patterns specific to the application requirements,  featuring a redundant system handling upto 14000 I/O points. 

The ATE monitors various aspects of the launch vehicle during this count down phase and assists in automating launch process. This product has been very reliable in operation since 2001. The ATE consists of precision analog input signal conditioners and digitizers and discrete as well as relay logic. One of the specialised modules used for fail/safe automation is an analog comparator which is programmable to carry out safety monitoring, independent of the software for fail/safe operation purposes. This world class system was implemented by Data Patterns against strong competition and proved it's reliability over many launches of the PSLV and GSLV from the Launch Pad.
