GMPC II communication driver is the driver to communicate with power meter GIMAC/GIMACII/GIMACIII/uRTU(or uRTU II) model of LSIS Co., Ltd. in Korea.
uRTU or uRTU II 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 uRTU 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 uRTU or uRTU II
Read schedule setting parameters are as follows:
1) STATION – uRTU or uRTU II controller station number = 0 ~ 255.
2) Controller Model – Model = uRTU or uRTU2 (when using uRTU, uRTU II model).
3) Read data type – Data type = 0, 1, 2, 3, 4, 5.... ( Cmd - 10h, refer to reference manual of uRTU )
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 uRTU equipment's setting value by using write settings.
Note) Write for uRTU can control when the equipment's setting is 'remote'.
Digital Write
Digital write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION uRTU controller station number = 0 ~ 255.
3) ADDRESS Control command number(hex-decimal unit), refer to <Table 7>.
Model(EXTRA1) = uRTU.
0000 ~ 000F – digital output 0 Bit ~ F Bit,
EXTRA2 : 0 = ON/OFF control, 1 : 2000 mSec pulse output.
Model(EXTRA1) = uRTU2.
0000 ~ 0007 – digital output 0 Bit ~ 7 Bit.
EXTRA2 : 0 = ON/OFF control, 1 : 2000 mSec pulse output, 2 : 1000 mSec pulse output, 3 : 1500 mSec pulse output, 4 : 2000 mSec pulse output.
0008 ~ 000B РCoefficient value remote Clear, ˞Ȑ point 1 ~ 4.
000F – all Coefficient value remote Clear.
4) Extra1 Model name.
uRTU – uRTU,
uRTU2 – uRTU II.
5) Extra2 Selection of normal or pulse output, refer to <Table 7>.
