Data strings:-
Protocol C1 – Continuous output
Meter sends: 8 characters<CR><LF>
e.g.
20 20 20 20 20 2D 31 37 0D 0A
20 20 20 20 2D 31 2E 36 0D 0A

20 20 20 20 20 20 4F 52 0D 0A
20 20 20 20 20 20 55 52 0D 0A
Protocol H1 - GPS clock data format for use with ASR-GPS
Protocol P1 – Polled ASCII
Controller sends: <STX> ADDRH:ADDRL r <ETX> e.g. 02 46 37 72 03 ( to device F7)
Meter replies <STX> 8 characters <ETX>
e.g.
02 20 20 20 20 20 2D 31 37 03
02 20 20 20 20 2D 31 2E 36 03

02 20 20 20 20 20 20 55 52 03
Protocol P2 – Polled ASCII Modbus - See next page
When you have finished setting the meter, put the lockout switch in its ON position now, to
prevent your settings from being changed.

RS232 or RS485 depending on installed board.
250 VAC Optically isolated from input, logic, excitation, power,
alarms and serial communications ports
Derived from displayed value, which is updated 10 times per
second. Any filtering applied to the display will be applied to the
serial data output also.
The analogue output is derived from the displayed value, so if your
display has a non linear response, and you are using the display's
lineariser function, the output will follow the display directly.
Accuracy better than +/- 10 seconds per month (DS3231SN)
