IDS440 Users Manual version 4.2 Set Operation Parameters
32
Serial I/O Ports
The IDS440 is equipped with two bi-directional serial communication ports that can
communicate to an optional printer, a computer, bar code reader, a score board or other
serial communication devices. The baud rate and format can be set independently for
each port. Serial port 1 is normally used to output weight data and ID reports to a
printer. Serial port 2 is normally used for continuous output of weight data. Continuous
transmission can be enabled or disabled and the output format can be customized using
Parameters 27 and 28.
Communication between serial devices requires that both devices have the same baud
rate (transmission speed), data bit length, and parity. The mode parameter selects the
data bit length and parity the baud parameter selects the baud rate.
Parameter 23 Serial Port 1 Mode (4 [8 data bits, no parity])
Enter the mode number from the table below to select the mode parameter in the mode
description column.
Mode Number Mode Description
1 7 data bits, no parity
2 7 data bits, even parity
3 7 data bits, odd parity
4 8 data bits, no parity
5 8 data bits, even parity
6 8 data bits, odd parity
Parameter 24 Serial Port 1 Baud Rate (1 [9600 baud])
Enter a baud number from the table below to select a baud rate from the description
column. (*HS baud rates for the 100 samples per sec version only).
Baud Number Baud Description
1 9600 Baud
2 4800 Baud
3 2400 Baud
4 1200 Baud
5 600 Baud
6 300 Baud (* HS 19.2K)
7 150 Baud (*HS 38.4K)
