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 concentrator.
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 center.
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 normal operating.
IO3:Network status indicator light. It will be turned on during the network time interval. It will not be turn on during other time interval.
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: 126.96.36.199,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.
