Delta Electronics Temperature Controller DTE - Manual (Page 2)

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).

Error Codes:
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.
H1000 Error description
H8001 EEPROM cannot be written in.
H8002 Input sensor is not connected.
H8003 Group INB is not connected.

for (j = 0; j < 8; j++)
{ if (reg_crc & 0x01) reg_crc = (reg_crc >> 1) ^ 0xA001;
else reg_crc = reg_crc >> 1;
