A.02 BATTERY
The VIPer807 comes with a 360mAh TL5186 TADIRAN battery. It powers the System
Controller's Real Time Clock and CMOS Setup, whenever the board is powered down.
The TADIRAN TL5186 has a shelf life of approximately 10 years (under "no-load"
conditions). The actual life of the battery depends on environmental (temperature)
conditions. The TADIRAN TL5186 has an operating range of -55
characteristics vary with temperature.
The voltage supplied by the battery is 3.6 volts. This can be verified with a standard
voltmeter at the battery socket's two extreme pins (if you use the pin on the soldered side,
you do not have to remove the battery).
The TADIRAN TL5186 is UL recognized. Its UL component recognition is MH12193.
Jumper W27 enables the Internal Battery's power. Removing the W27 jumper has the
same effect as putting the battery in storage; TEKNOR always ships its board with battery
jumper removed in order to increase the life of the battery.
An External Battery may be used. In such a case, pins 2 and 3 of jumper W27 should be
shorted.
Please refer to Section 3 for jumper location and settings.
The VIPer807 board has a special feature that allows the CMOS RAM Setup to be saved
in Flash EPROM memory. This feature eliminates battery dependance by saving and
recovering the CMOS RAM Setup from Flash (only the time and date could be lost).
F In order to save your current CMOS RAM Setup in Flash, you must update the
VIP-UP Setup (with F10), while the "Use Flash To Store CMOS RAM SETUP"
(first screen) is set to "Yes". See section 10.01 for more information.
