*MTBF calculations are based on the commercial MBTF ratings of the PCB boards and components used in the product. LAVA’s calcul ations take into account
the infant mortality and constant failure and wearout rates of the components as well as of the finished products. LAVA’s testi ng excepted such variances as:
mishandling of finished product, shipping damage, and damage caused during installation. LAVA’s MTBF rates were ascertained as a mix of actual product
experience balanced with predictions made by analyzing known factors for newer products.
MTBF ratings are provided as a service to our customers to help in planning service level agreements, etc. LAVA Computer MFG Inc.’s Limited Lifetime Warranty
will be the deciding factor in all warranty issues.

*Signal degradation increases (ie: maximum distances decrease) if DTE and DCE do not share a common ground, or if there is high line noise. Line noise is
greatly reduced with a low capacitance cable. The specification for RS-232C serial communications allows for transmission up to 15m at 20 kbps.
