This PepCard product is carefully designed for a long and fault-free life; nonetheless, its life expectancy can be drastically
reduced by improper treatment during unpacking and installation.
Observe standard anti-static precautions when changing piggybacks, ROM devices, jumper settings, etc. If the product
contains batteries for RTC or memory back-up, ensure that the board is not placed on conductive surfaces, including
anti-static plastics or sponges. These can cause shorts and damage to the batteries or tracks on the board.
When installing the board, switch off the power mains to the chassis. Do not disconnect the mains as the ground
connection prevents the chassis from static voltages, which can damage the board as it is inserted.
Furthermore, do not exceed the specified operational temperature ranges of the board version ordered. If batteries are
present, their temperature restrictions must be taken into account.
Keep all the original packaging material for future storage or warranty shipments. If it is necessary to store or ship the
board, re-pack it as it was originally packed.

will also be excluded from this warranty.
A customer who has not excluded his eligibility for this warranty may, in the event of any claim, return the product at the
earliest possible convenience, together with a copy of the original proof of purchase, a full description of the application it is
used on, and a description of the defect; to the original place of purchase. Pack the product in such a way as to ensure safe
transportation (we recommend the original packing materials), whereby PEP undertakes to repair or replace any part, assembly
or sub-assembly at our discretion; or, to refund the original cost of purchase, if appropriate.
In the event of repair, refund, or replacement of any part, the ownership of the removed or replaced parts reverts to PEPModular Computers, and the remaining part of the original guarantee, or any new guarantee to cover the repaired or replaced
items, will be transferred to cover the new or repaired items. Any extensions to the original guarantee are considered gestures o

The PB-TIN2 is an optoisolated, general purpose timer piggyback for the VMOD-2 and CXM-IMOD range of PEP
boards. Three independent timers with 16+8 bit resolution and possessing 9 modes of operation are galvanically isolated
from the process. Three inputs and an output per counter may be software configured.
