Serial link
This screen is used to configure the Serial link (COM 1). The address, the baud rate, the format, and
the communication protocol are configurable :

The analyzer address is composed of 4 characters which define the device code for remote
controlling, or when the device is integrated into a network.

The speed of communication of the serial link is stated as the baud rate (bits per seconds): 1200,
2400, 4800, 9600, 19200, 38400, (limited to 19200 bds at present time).

The data transmission format is selected from the following: 7,n,1; 7,o,1; 7,e,1; 7,n,2; 7,o,2; 7,e,2;
8,n,1; 8,o,1; 8,e,1; 8,n,2; 8,o,2; or 8,e,2. This is a common shorthand notation for a serial port
parameter setting in asynchronous mode. The first character is the number of data bits (can be 7
or 8). The second character is the parity control (can be n (for non), e (for even), or o (for odd)).
The third character is the number of stop bits (can be 1 or 2).
Examples: 8,n,1: 8 data bits, no parity bit, 1 stop bit
8,o,1: 8 data bits, 1 odd parity bit, 1 stop bit
8,e,2: 8 data bits, 1even parity bit, 2 stop bits

Communication protocol: Mode 4,JBUS, PRN.

Mode4 is a communication protocol proper to Environnement SA, designed to send and
receive data. It works according to master/slave mode.

JBUS protocol is an industrial protocol designed to dialog with automatons. It works according
to master/slave mode.

PRN protocol is a text data frame containing information about the measures (compound
name, value, unit) of the analyzer and automatically transmitted, without request, at
programmable intervals.

Interface : RS-232 or RS-422.
These are standards of communication interfaces. RS-422 enables multipoint communication
management for industrial controllers and RS-232 enables point-to-point communication
management: analyzer
