15.3.3 Communication programs

In this paragraph are illustrated two examples of communication programs between the OSP and an IBM or IBM

compatible PC.

Example A:

Data transfer from OSP to PC

Connect OSP through adapter BB530001 (TTL-RS232 converter), to personal computer communication port COM1.

You will read temperature value.

Example B:

PC instructions to OSP

Connect OSP through adapter BB530001 (TTL-RS232 converter), to personal computer communication port COM1.

You will set emissivity to 0,80.

Example A:

1Ø CHAR = Ø

2Ø IDNAME = 1

3Ø INSTRUCTION = 0

35 OPEN "COM1: 96ØØ, N,8,1,CD,CS,DS,RS" FOR RANDOM AS # 1

4Ø PRINT #1, CHR$ (IDNAME);:REM TRANSMIT IDNAME TO OSP

5Ø WHILE LOC (1) = Ø: WEND: REM WAIT RECEIVING IDNAME FROM OSP

6Ø IDNAME = ASC (INPUT$ (1, 1)): REM READ RECEIVED IDNAME FROM OSP

7Ø PRINT #1, CHR$ (INSTRUCTION);

8Ø WHILE LOC (1) = Ø: WEND

9Ø INSTRUCTION = ASC (INPUT$ (1, 1))

1ØØ PRINT #1, CHR$ (CHAR);

11Ø WHILE LOC (1) = Ø: WEND

12Ø DATA 1 = ASC (INPUT$ (1, 1))

13Ø PRINT #1, CHR$ (CHAR);

14Ø WHILE LOC (1) = Ø: WEND

15Ø DATA 2 = ASC (INPUT$ (1, 1))

16Ø PRINT #1, CHR$ (CHAR);

17Ø WHILE LOC (1) = Ø: WEND

18Ø DATA 3 = ASC (INPUT$ (1, 1))

19Ø PRINT #1, CHR$ (CHAR);

2ØØ WHILE LOC (1) = Ø: WEND

21Ø DATA 4 = ASC (INPUT$ (1, 1))

22Ø PRINT #1, CHR$ (CHAR);

231Ø WHILE LOC (1) = Ø: WEND

24Ø CHKSUM = ASC (INPUT$ (1, 1))

25Ø IF CHKSUM <> ((DATA1 + DATA2 + DATA3 + DATA4) AND &HFF) THEN PRINT "Error": END

26Ø VALUE = DATA3 * 256 + DATA4

27Ø IF VALUE > 32767 THEN VALUE =VALUE - 65536: REM 2'S COMPLEMENT
