A: The RS232 of the 4030 has two modes:
1. Real Time FID mode: This mode provides some raw data from the FID that is used for application research at the factory.Real time FID output may be toggled by pressing the down key when in the main operation mode.
2. A standard output mode: this is the preferred customer output. It consist of a text string that is sent by the analyzer every two seconds.
The standard output is toggled in the same manner as the real time FID output. When the real time FID output is active, the standard output is inactive and vice-versa.
The standard output message is sent once every 2 seconds. Each time the message advances to the next active Analysis Group, so if 'BNZ' and 'ETH' are set up to be active, then the message will reference each group alternately. The formatting is not as straightforward, the examples should suffice.
examples:
AAA 12 ppb R3 SPAN CR LF 0x00
note: AAA is a replaced by the 3-letter symbol for the group ('BNZ', 'ACA', 'ETH', etc...)
note: CR -> the carriage return character (ascii 0x0D)
note: LF -> the line feed character (ascii 0x0A)
note: 0x00 -> a null character (ascii 0x00)
note: in a ppb range, there are no numbers to the right of the decimal place
note: Range is '3'
note: SPAN indicates in span mode. When not in span mode, 'AL' is sent (below).
AAA 12.23 ppm R2 AL CR LF 0x00
note: in a ppm range, there are numbers to the right of the decimal place
note: in this example alarm 1 and alarm 2 are not alarming
AAA 12.23 % R1 AL1 CR LF 0x00
note: in a percent range, there are numbers to the right of the decimal place
note: in this example alarm 1 is alarming
AAA 12.23 % R1 AL2 CR LF 0x00
note: in this example alarm 2 is alarming
AAA 12.23 % R1 AL12 CR LF 0x00
note: in this example alarm 1 and alarm 2 are alarming
