through a hardware interface on the Real-Time Clock option card. This RS485
type interface allows connection of up to 32 PAXCK meters in a two-wire
multidrop network, at distances up to 4000 ft. (See Section 4.6, Real-Time
Clock Wiring).
(
hour (at 30 min. past the hour), the Host meter outputs a time synchronization
pulse onto the network. Upon receiving the synchronization pulse, each Slave
meter automatically adjusts the Minutes and Seconds of its RTC Time setting to
synchronize with the Host. Synchronization, using the Real-Time Clock Wiring,
adjusts the Minutes and Seconds only, and does not change the Hours, AM/PM,
Day or Date settings in the Slave meter's RTC.
PAXCKs that are connected in an RS485 network (RS485 Serial Option cards
required). In this configuration, one meter is designated as the Serial RTC
Master by setting the meter's address as 98 or 99 (see Serial Real-time Clock
Addressing in Master Module 7). Every hour (at 30 min past the hour), the
Serial RTC Master / Host will transmit the full time (Hours, minutes, seconds)
to all meters through the RS485 serial card wiring network. The time, date, or
day will also be transmitted and updated in the Slaves when changed in the
programming of the Serial RTC Master. Only one meter should be configured
as Master and that meter should also be configured as the Host.
accuracy timekeeping. The oscillator is factory calibrated* and optimized for
25°C ambient temperature operation. Since the PAXCK is designed to operate
over a wide temperature range, and since the accuracy of a crystal oscillator
varies with ambient temperature, some drift in the RTC time may be observed
over an extended period. This is primarily seen in high or low temperature
installations. To compensate for the wide operating temperature range, a
calibration or “Offset” value can be entered, which effectively slows down or
speeds up the clock to maintain accurate timekeeping.
