Step 2
Confirm that the Serial Port configurations are correctly set.
Step 3
Reboot the Tester to activate the configuration.
Character Format Parameters
To define the character format, check the following conditions
and set the appropriate parameters:
• Data Length: Specifies the number of bits of each character
excluding start, stop and parity bits.
• Parity Enable: Specifies parity check mode of each character.
• Stop Bits: Specifies number of stop bits of each character.
Flow Control
If the Tester cannot be controlled with the controller caused by
receiver buffer full of the Tester, use Xon/Xoff flow control. To
use the Xon/Xoff flow control with the Tester, set the Xcontrol on
the [Configuration] screen to
receives the (decimal value of 19), stop transmitting data.
Xoff
When the controller receives the
resume transmitting data.
Flow control using the control lines (CTS, DSR and DCD) are
not available.
Data Transfer Errors
On the serial interface several type of errors may occur during
data reception. The errors may occur by any of the following
factor.
• Parity error: The parity bit on a receiving character does not
match the parity bit expected by the receiver.
This error is most commonly caused by line
noise. In this case, reducing the cable length or
using a shielded cable may solve this error.
• Framing error: The start bit and stop bit do not match the
timing expectations of the receiver. This error
is most commonly cased the cable line noise.
In this case, reducing the cable length or using
a shielded cable may solve this error.
