3. Communication setting
TEMP1500 provides flexible communication interface RS232C or RS485 from Control Unit directly.
▶In [Figure 1], Using a flat-blade screwdriver to remove the cover.
▶In [Figure 2], Communication settings by moving the socket
▶It is recommended to use tool like tweezers for setting socket to pin-header correctly.
☞Make sure setup completed correctly.

Slave unit address of TEMP1500.
③Command
Function Command for communication. (Refer to 5.2 ~ 5.10).
④Delimiter

⑤Data
Formal text strings regulated by communication command rule.
⑥Check Sum
-‘SUM' protocol is a more sophisticated one which includes Check Sum as an error check.
- Check Sum is calculated as following.
1) Add the ASCII code of characters from the character next to STX one by one up to the character prior to SUM
2) Represent the lowest one byte of the sum as a hexadecimal notation (2 characters).
⑦, ⑧Protocol Tail
ASCII code to close communication command by indicating CR(0xOD) and LF(0xOA).

█Example for SUM
◈Example
To read the consecutively D-Register from D0001 (NPV) to D0005 (MVOUT)
- Rrquest : [stx]01RSD,05,0001[cr][lf]
- Rrquest (with CheckSum) : [stx]01RSD,05,0001C8[cr][lf]
☞As shown below, hexa decimal value adding each text at 01RSD,05,0001 by ASCII code is 2C8, and lower
digit 2 characters C8 will be used for CheckSum.

STD
Register arbitrary single address to monitor (D-Register Monitoring Set)
CLD
Read data in address registered by STD command (D-Register Monitoring Call)
☞Each Command can read or write up to 64 D-Register and all of the SED/CLD data will be reset by power OFF,
so the data should be registered again.

- Request : [stx]01RSD,03,0001[cr][lf]
- Request (with CheckSum) : [stx]01RSD,03,0001C6[cr][lf]
([stx] = 0x02, [cr] = 0x0d, [lf] = 0x0a)
Response data will be same as below, when 50.0 of D0001 (NPV) and 30.0 of D0002 (NSP)
- Response : [stx]01RSD,OK,01F4,0000,012C[cr][lf]

※Converting procedure 4digits hexadecimal response to decimal value.
①Radix conversion (Decimalize) : 01F4(hexadecimal) →500(decimal)
