Modifying serial interface parameters
In practice, on the one hand, you need to improve the baud rate of the serial interface to
save the upgrade time, and on the other hand, you need to lower it to guarantee the
transmission reliability. This section introduces how to modify the baud rate of the serial
interface.
Step1 Select 2 on the main menu to enter the serial submenu.
Step2 Select 5 on the serial submenu to enter the baud rate setting menu as follows:
========================<BAUDRATE SET>=======================
|Note:'*'indicates the current baudrate |
| Change The HyperTerminal's Baudrate Accordingly |
| Press 'Enter' to exit with things untouched. |
|--------------------<Baudrate Available>-------------------|
| <1> 9600(Default) * |
| <2> 19200 |
| <3> 38400 |
| <4> 57600 |
| <5> 115200 |
| <0> Exit |
=============================================================
Enter Your Choice(0-5):
Step3 Select a proper baud rate, 5 for example for the baud rate of 115200 bps. The following
information is displayed:
Baudrate has been changed to 115200 bps.
Please change the terminal's baudrate to 115200 bps, press ENTER when ready.
At this time, the baud rate of the serial interface on the SecBlade card is modified to 115200
bps, while that of the HyperTerminal is still 9600 bps. Therefore, the SecBlade card and the
HyperTerminal cannot communicate with each other. You need to change the baud rate
on the HyperTerminal and make it consistent with that of the serial interface on the
SecBlade card so that they can communicate with each other.
Perform the following operations on the HyperTerminal:
Step4 Select Call > Disconnect to disconnect the HyperTerminal connection.
