How to Force Loader Mode Manually
Thermo Scientific
You can try repeating the last step, using the following options:
• Retry with old file.
• Load new file.
You might check the communication by using the Info button.
This section contains information about troubleshooting the PAL Loader software.
Note You can use PAL Loader software version 2.1.x for the PAL System. It is backwards
compatible with PAL Systems.
If you cannot establish serial communication with the PAL Loader software version 2.1.x,
check the following points:
• Is the COM port on the computer available and correctly addressed?
Are default settings verified?
• Is the PAL Loader software COM port setting correct?
If no RS232 (serial) port is available on the computer, use a USB/Serial converter. Use the
type recommended by CTC Analytics: PNo.: USB-Ser2.
The PAL RS232 cable has a crossed wiring connection.
PN: 00950-01-00332 (3 m length, standard cable) or
PN: 00950-01-00333 (6 m length, optional cable)
If basic conditions are met but you still cannot establish communication from the computer
to the Accela Open Autosampler, you must force the PAL System into Loader mode.
This action might be necessary if the PAL Firmware has been partially corrupted.
 To force the Loader Mode manually
1. Turn off the power from the PAL System.
2. Turn on the power again.
3. Turn off the power from the PAL System within a time window of approximately 3 to
5 seconds again (turn it off before the startup logo is displayed on the screen).
4. Turn on the power again.
