Megatec Extended Communication driver

Megatec Extended Communication driver is the driver to communicate with Three-Phase UPS of Mega System Technologies,Inc. in Taiwan.

Note) G1, G2, G3, GF read command can communicate when using 3 phase connection.

1. Read Settings

<Figure 1> is read setting example of Megatec Extended communication driver.

<Figure 1> Read setting example of Megatec Extended communication driver

Device part of <Figure 1> input Com Port(COM1), Baud Rate(2400), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively. ( fixed to 2400, 0, 8, 1 )

Megatec Extended communication driver read schedule

Read schedule setting parameters are as follows:

1) Station – don't care.

2) Read command – Command = G1, G2, G3, GF, I, F, Q1.

G1 = read of UPS Read Time Data,

G2 = UPS Status Inquiry,

G3 = read of UPS Realtime Data 3 Phases,

GF = read of UPS Rating Information,

I = read of UPS Information,

F = read of UPS Rating Information,

Q1 = Status Inquiry.

3) Read start address – don't care.

4) Save start address for Communication Server – Saving start address of Communication Server.

5) Read Size – fixed to 1.
