Page 26 RPC-30

DESCRIPTION

The RPC-30 has a built in battery backed

Calendar/clock. When used in conjunction with the

DATE$ and TIME$ commands, the current date and

time can be set and read.

The life of the battery depends upon the power

consumption of RAM in U10. Generally, you can

expect a battery life of 5 to 10 year s.

The clock chip, U17, contains a built in cr ystal.

Accuracy is about 1 minute/month and is not adjustable.

Refer to the CAM BASIC Programming Manual for

more specific command information.

SETTING DATE AND TIME

The date and time can be set while running a program or

in the immediate mode. Date and time are treated as

strings and not numbers. T o set the date and time:

date$="03-11-93"

time$="13:56:00"

To retrieve date and time as part of a program:

2000 DA$ = DATE$(0)

2010 TI$ = TIME$(0)

You can also print the date and time in the immediate

mode:

pr time$(0)

13:56:03

The clock is turned on and off and set for 12/24 hour

mode using the CO NF IG CL OCK statement.
