Chapter 9 Auxiliary Function
9.1 Communication
PBAT-GATE with maxim 4 RS485 port, 4 of them
independent from each other. PBAT600,
PBAT61-02, PBAT61-12
Please refer to following wiring example, in the actual application,
In order to prevent signal
reflection, normally need to add on parallel an approximately120-ohm resistor by the end of
network
PBAT-GATE with 2 port RJ45, support IEEE-802.3 Ethernet standard10BaseT/100BaseTX
9.1.1
Communication media
Communication use standard 22#
shielded Twisted Pair, total length no more than
1200 meter long
9.1.2
Communication Protocol
RS485 port to support the international common MODBUS-RTU protocol. Please refer to
the corresponding "_MODBUS communication protocol" manual for the specific agreement.
9.1.3
Communication Parameter
Whether the instrument can communicate with the master is the premise of whether the
communication parameters are set correctly. Communication Parameter including:
1. Meter address ID
2. Baud rate: 4800, 9600
9.1.4
Communication port against strong electrical function
Short time (within 5 minutes) strong electricity connection (220V AC) no damage, after move
away strong electricity will recovery back to normal communication
9.2 Clock
Battery monitoring system built in NTP server and with
time synchronization function.
