Trouble Shooting
1 When the CT-510 is configured via the Console port using the VT-100
program, like HyperTerminal, the interface doesn’t respond properly. For
example, the arrow keys cannot work when I need to move the cursor.
Solution1: We recommend you to upgrade your HyperTerminal to Edition 5 if
you are using Edition 4 or below.
Solution2: If you don’t want Solution 1, you can upgrade the firmware of
CT-510 to Version 1.67 or above. For Version 1.67 and above, you can use
other functional keys to replace the arrow keys. For example, the function
of UP arrow key can be replaced by holding down CTRL-W. For descriptions
of other arrow keys, please refer to Section 3.2.3.
2 Parameters are lost after restart
When you adjust or change the parameters, you should save the parameters
into the RAM by holding down Ctrl-S keys. This procedure only saves the
parameters temporarily. Therefore, before you exit the system, you should
save the configurations into the flash memory by entering the MAIN/WRITE
menu and then reboot the system by entering the MAIN/REBOOT menu.
