SERIAL RTC MASTER ADDRESSING
Card and an RS485 Serial Communication Card installed, can act as a Serial
RTC Master, when programmed with meter address 98 or 99. With this feature,
whenever the Master meter's time, date or day is changed, through quick or
main programming, it will transmit and make the same change to the other
PAXCK's on the RS485 bus. Only one meter should be configured as Master.
This Master, with address 98 or 99, should also be programmed as the “Host”
in module
the other PAXCK Slaves will update hours, minutes and seconds to the Host
once an hour and the Real-Time Clock Wiring (terminals 16-18) will not be
necessary.
meter will transmit the change to all meters on the RS485 bus addressed as “0”.
This is useful when using both newer or older software code version meters, or
when another master (computer, operator interface) is not being used.
version 2.3 or greater, meters on the RS485 bus using a global broadcast address
suffix. This is useful when it is necessary to have unique or other than 0 serial
meter addresses or when having a computer or operator interface connected.
SENDING SERIAL COMMANDS AND DATA
command character must be constructed. A command string consists of a
command character, a value identifier, numerical data (if writing data to the
meter) followed by the command terminator character * or $.

procedure details construction of a command string:
1. The first characters consist of the Node Address Specifier (N) followed by a

1 or 2 character address number. The address number of the meter is
programmable. If the node address is 0, this command and the node address
itself may be omitted. The address suffix , “?” is the global broadcast address
specifier. A command string that is sent with N? prefix will be accepted by
all PAXCKs on the RS485 network (software code version 2.3 or greater).
This is useful for setting all meters to the current time, date or day that may
have unique meter addresses on a bus. It is important not to send (P)rint or

responding at the same time. This is the only command that may be used in
conjunction with other commands.

Register Identification Chart
1. Register Names are also used as Register Mnemonics during full transmission.
2. The registers associated with the P command are set up in Print Options (Module 7).
3. Unless otherwise specified, the Transmit Details apply to both T and V
Command String Examples:
1. Address = 17, Write 350 to Setpoint 1
2. Address = 5, Cycle Counter value, response time of 50 to 100 msec. min.
3. Address = 0, Reset Timer value
Transmitting Data To the Meter
Register Identification Chart. Leading zeros are ignored. The meter ignores any
decimal point and conforms the number to the scaled resolution. (ie. The meter’s
scaled decimal point position is set for 0.0 and 25 is written to a register. The value
of the register is now 2.5. In this case, write a value of 250 to equal 25.0).
For RTC Time [C] and Date [D] Value:

Transmitting Data From the Meter
