Delta Electronics DTE Prospecto

4. This function will consume 3 ~ 5 seconds more when you switch on DTE.

RS-485 Communication

1. DTE supports baud rates 2,400/4,800/9,600/19,200/38,400/57,600/115,200 bps and does not support communication

format 7, N, 1/8, E, 2/8, O, 2. Communication protocol = Modbus ASCII or RTU.

2. Function codes: H03 = read maximum 8 words in the register; H06 = write 1 word into the register.
3. Address and contents: Every parameter has 2 communication addresses. One is numbered by the function of the

parameter, and the other is by the order of channel (as shown in the table below).

The error codes can be read from address H1000 ~ H1007. When the input operation is in normal status, H1000 ~ H1007 are
for input values. When input error occurs (except for stable status and input exceeding the range), DTE will read error codes
in H8001 ~ H8002.
