Battery-Backed Clock

An AT-compatible battery-backed real-time clock (with CMOS RAM) is standard on the Little Board

P6d module. A 3.0 volt Lithium battery soldered to the board power s the clo ck. Battery drain f or

the clock is less than 0.4 uA. This battery will support the clock for more than 10 years of no rmal

usage.

The factory initializes the real-time clock and various parameters in the configuration memory for a

standard configuration. The factory sets the date and time , but it may n ot be se t for you r time

zone. Use Setup to change these values as needed.

The contents of the configuration memory are also stored in an on-board EEPROM. The ROM BIOS

reads the EEPROM to get configuration information if the CMOS RAM data is lost. This means th e

board will function if the battery fails.

Note

The real-time clock date and time will not be correct without a

battery, or after the battery fails.

Serial Ports

The Little Board P6d module provides four RS232C serial ports, Serial 1 and Serial 2 at J8, and

Serial 3 and Serial 4 at J11.

Serial 1 and Serial 2 have full modem support. Serial 3 and Serial 4 support only RXD, TXD, RTS,

CTS. All ports support software selectable standard baud rates up to 115.2Kbps, 5-8 data bits, and

1, 1.5, or 2 stop bits.

Note

The IEEE RS232C specification limits the serial port to 19.2Kbps on

cables up to 50 feet in length.
