Baud Rate
The baud rate is the first parameter in the menu. The baud rate setting deter-
mines the serial communications transmission rate.
The baud rate parameter is indicated by,
bAUd
Serial baud rate parameter
Press “SET” to choose to set the baud rate. The current baud rate value is then
displayed.
2400 b
Current baud rate
The baud rate of the serial communications may be programmed to 300,
600,1200, 2400, 4800, or 9600 baud. Use “UP” or “DOWN” to change the
baud rate value.
4800 b
New baud rate
Press “SET” to set the baud rate to the new value or “EXIT” to abort the opera-
tion and skip to the next parameter in the menu.
7.12.2
Sample Period
The sample period is the next parameter in the serial interface parameter menu.
The sample period is the time period in seconds between temperature measure-
ments transmitted from the serial interface. If the sample rate is set to 5, for in-
stance, the controller transmits the current measurement over the serial
interface approximately every five seconds. The automatic sampling is disabled
with a sample period of 0. The sample period is indicated by,
SPer
Serial sample period parameter
Press “SET” to choose to set the sample period. The current sample period
value will be displayed.
SP= 1
Current sample period (seconds)
Adjust the value with “UP” or “DOWN” and then use “SET” to set the sample
rate to the displayed value.
SP= 60
New sample period
