1) The power cable should adopt the RVVB type 2×0.75mm2 or thicker cable, and install the earth-leakage protective device.
The power supply of concentrator should be stable and reliable, to
avoid can’t read the meter caused by the power outage.
2)The concentrator can store 31 day freezing data and 12 meter
reading day freezing data.If the concentrator will be power off at
the freezing time, it can’t produce the freezing data.
3)The concentrator has equipped with 2 antenna. The left side at
the top of case connects to the radio-frequency antenna, and the
right side connect to the GSM antenna.
4)Only install the antenna and mobile phone card, can power on the
5)If the management center adopts the fixed IP mode,need to make
sure the IP and port of concentrator is same as the management
5. Indicator Light Description:
IO0:TCP connection indicator light. When the concentrator connects
to the server, the indicator light will turned on. It will not be
turn on for other condition.
IO1:PPP connection indicator light.It will be turned on when the
mobile phone card registered to the mobile network. It will not be
turn on for other condition.
IO2:Operating indicator light. It will glitter under the system
IO3:Network status indicator light. It will be turned on during the
network time interval. It will not be turn on during other time
IO4:Meter reading time interval indicator light. It will be turned
on during the meter reading time interval. It will not be turn on
during other time interval.
GPRS Type Concentrator
1 Main Technical Parameters:
Operating Power:AC220V±20%,50Hz(single Phase)
Upward Communication :GPRS wireless mobile network
Downward Communication:Micropower wireless mode,470.79MHz,1200BPS
Power Consumption :≤10VA
Loading Capacity:Can manage 255 units of Collector
2 Working Condition:
Installation position requirements: The installation position must
has the China mobile GSM network signal coverage.
Management center requirements:Network server of data management
center must has the stable IP address. If has no IP address, it
need to equipped with a data transmission terminal (GPRS DTU)
3 Operating Method:
1)Set up the server IP and address
The default server of concentrator IP: 188.8.131.52,port
number:8001, address: 0001, administration division code: 0371.
Set up the parameters of concentrator through RS232 according to
stable IP and port of data management center. And set up the
address and administration division according to the actual need.
2)Fix the concentrator
Fix firmly on the concentrator according the concentrator fixing
hole position. If the concentrator will be installed outside, it
need to install in the protective box. Connect the GSM antenna to
the antenna terminals at the right side of concentrator, and the
radio-frequency antenna connect to the antenna terminals at the
left side of concentrator. Insert the GPRS function mobile phone
card into the SIM card slot.
The concentrator connect to AC power 220V, 50Hz according to the
wiring connection diagram.
4)Set up the concentrator operating parameters
It can set up the parameters after log in the management center.
Such as: date and time, meter reading time interval, network
maintenance time interval.
5)Download the meter address
Download the collector address of management center software and
meter address to the concentrator after finish to set up the
operating parameters of concentrator. After finish the downloading,
the concentrator can work normally.
