GMPC II communication driver is the driver to communicate with power meter GIMAC/GIMACII/GIMACIII/DPR model of LSIS Co., Ltd. in Korea.
DPR model communicate with GMPC controller( GMPC I, GMPC II, GMPC III, GMPC V, ... ) and computer read and write GMPC's data.
<Figure 1> is read setting example of GMPC II communication driver for DPR model.

Device part of <Figure 1> input Com Port(COM1 or TCP/IP, UDP/IP, etc), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively according to setting of GMPC.
Baud rate, parity bit, data bit, stop bit can set by using switch of rear or front panel(GMPC controller).
GMPC II communication driver read schedule for DPR
Read schedule setting parameters are as follows:
1) STATION – DPR controller station number = 0 ~ 255.
2) Controller Model – Model = DPR(when using DPR model).
3) Read data type – Data type = 0, 1, 5, 6.... ( Cmd - 10h )
4) Save Start Address for Communication Server – saveing start address of Communication Server.
5) Read Size – Read size. Fixed according to read data type. ( Refer to <Table 1>, <Table 2> )
6) Sub1 command - Input Sub1 command according to controller model.
7) Sub2 command - Input Sub 2 command according to controller model.

You can write DPR equipment's setting value by using write settings.
Digital Write
GMPC II communication driver for DPR model don't support digital write.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION DPR controller station number = 0 ~ 255.
3) ADDRESS Setting data type = refer to <Table 3>.
4) Extra1 Model name = DPR.
5) Extra2 Setting content = 0 ~ 5 or 255. ( refer to <Table 3> )
Note) Analog write for DPR equipment send write command to GMPC controller after reading the corresponding setting address(data).

Connection of I-NET communication cable
Please connect I-NET RS-485 communication cable to 2( Tx0 ), 4( Tx1 ), 6( Rx0 ), 8( Rx1 ) connector such as <Figure 4>.
Note) When you connect DPR and GMPC, you have to connect Rx = Tx, Tx = Rx respectively. ( I-NET cable = offered by LSIS Co., Ltd. when you buying GMPC or DPR )
Connection of GMPC V almost equal with GMPC III. So you can refer to connection of GMPC III part.
<Figure 6> is apperance of GMPC V controller.

Note) Password input method : you can input 'password' by using 4 button of frong panel. ( Inital(default) Password : press 'FUNCTION', 'SELECT', 'UP', 'ENTER' button 2 times by turns )
Setting of GMPC V)
1. Time & Date : Date and Time setting of GMPC V.
2. Model : Model, protocol and communication method of GMPC V.
Model | Protocol : select GMP(I-NET protocol of GMPC) or MODBUS protocol,
Model | Media : select communication media of GMPC V.
Model | Main Port : select Primary(P) or Secondary(S).
3. Serial : select Com1 or Com2 port of GMPC V.
4. Network(This) : select LAN1, LAN2 Ethernet port.
Network(This) | Ethernet Port : select primary ethernet port of GMPC V.
Network(This) | IP_0 : input IP Address of Primary Ethernet,
Network(This) | Port_0 No_0 : input Port number of Primary Ethernet,
Network(This) | Netmask_0 : input Subnet mask of Primary Ethernet,
Network(This) | Gateway_0 : input Gateway IP Address of Primary Ethernet,
Network(This) | Host_IP0 : input Host(PC, etc) IP Address of Primary Ethernet.
After setting GMPC V controller, save the setting by using 'ENTER' button.
Also, you have to reset(power off and power on) in order to apply the setting value. (don't reset, GMPC V use the old setting value)
Note) When you using the 'Ethernet' communication, you have to set Host(PC, etc) IP address at GMPC V controller.
Also if you don't use gateway at network, please set 'Gateway' IP address to '0.0.0.0'.
Note) You must input power for the first time of GIPAM-2200, etc, and input power GMPC V.
If you input power GMPC V the first and input GIPAM-2200, etc, GMPC V can't find connected equipment. So it may not be able to communicate with connected equipment.
