9.11 Serial Interface Parameters
The serial RS-232 interface parameters menu is indicated by,
SErIAL
Serial RS-232 interface parameters menu
The serial interface parameters menu contains parameters which determine the
operation of the serial interface. These controls only apply to instruments fitted with
the serial interface. The parameters in the menu are — baud rate, sample period,
duplex mode, and linefeed. Press “UP” to enter the menu.
BAUD Rate9.11.1
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
Flashes “bAUd” and then displays the setting
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.
Sample Period9.11.2
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, the in strument
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
Flashes “SPEr” and then displays the setting
SP= 1
Current sample period (seconds)
