Setting The Real Time Clock And Calendar; Year Readback; Adding A Correction Factor To The Real Time Clock - Arcom RC-210 Operation And Programming Manual

Setting the Real Time Clock And Calendar

It is necessary to set the Real Time Clock and Calendar before you'll be able to use the features they provide, such as the time
readback and the Scheduler. When programming, it will read back the current time in order to confirm your entry.
*5100 hh mm where "hh" is the hours in 24 hour time and "mm" is the minutes. Both must consist of 2 digits
Examples:
*5100 01 22 Set the clock to 1:22 AM
*5100 15 04 Set the clock to 3:04 PM
*5101 mm dd yy
current day of the week, month, day and year in order to confirm programming.
Examples:
*5101 06 11 03 Set June 11, 2003 as the current date
*5101 10 04 11 Set October 4, 2011 as the current date

Year Readback

You may turn ON/OFF the readback of the year when the date is spoken.
*51020 Turn OFF year readback
*51021 Turn ON year readback

Adding A Correction Factor To The Real Time Clock

As is the case with any clock that is not referenced to standard such as WWV, the RC-210's Real Time Clock may gain (or lose) a few
seconds over time. This is unavoidable due to temperature changes, crystal tolerances, etc. Fortunately, the RC-210 allows you to
"bump" the clock + or - up to 60 seconds in order to obtain the best accuracy possible.
For example, you may notice after your RC-210 has been running for a week that its Real Time Clock has lost 2 seconds. With this
command, it is a simple matter to add 2 seconds to the clock's time.
*5105 2 Add 2 seconds to the Real Time Clock's current time
*Note: If you need to subtract seconds from the Real Time Clock, preface the seconds with an "A". For example *5105 A 3 will
subtract 3 seconds from the clock's current time
In addition to adding 2 seconds to the time, this command also stores this correction factor into non-volatile memory. This allows you to
set a scheduler setpoint (in our example above, you'd program a setpoint to run once a week) and automatically apply it to the clock by
storing the Macro Function Number into a Command Macro and have the scheduler run that macro at, let's say, Friday night at
midnight. See the Command Macro and Scheduler programming sections of this manual for details.
Set the calendar to MM month, DD day, YY year. When programming, the controller will read back the
