Section 12.2 Received 3 NAKs or Timeout in sendVISAPacket()
12.2 Received 3 NAKs or Timeout in
sendVISAPacket()
This error message displays on the computer or cash register. The following sections list
possible causes and corresponding solutions.
12.2.1 There may be a loose connection between the host and the
Ingenico 6500
Ensure the cables are securely connected.
12.2.2 The communications port settings and EFT/NCR protocol setting
in the Ingenico 6500 may be wrong
The following procedure explains how to compare the configuration that you have in your
IBMEFTDL file to make sure that it is the same as the default setup configuration in your
Ingenico 6500 terminal (for details, see 12.3 Default Setup Configuration on page 98).
1. To find the communication port settings in your IBMEFTDL file, open the download
batch file, search for the keyword "ibmeftdl", and find the following parameters:
— /b: the number following this parameter is the required RS232
baud rate.
— /d: the number following this parameter is the required RS232 data
bits.
— /t: the character following this parameter is the required RS232
parity setting. An "n" means none parity, "e" means even, "o"
means odd parity.
2. Write these parameters down.
3. Next, go the Ingenico 6500 terminal to read the current settings to see if they are the
same. Restart the terminal by pressing [1] + [OK] + [CAN]; while it is restarting, access
the Extended Menu by pressing [1] and [3] simultaneously.
4. Select System Info, and then select View Parameter. The screen displays the current
download configuration for the port the terminal has configured to do the download, the
baud rate, data bits, stop bits, and parity of that port.
5. Compare these settings to the IBMEFTDL parameters that you wrote down in step 2;
they should be the same. If not, change them using the following steps.
6. From the Communications menu, press [Can] twice to return to the Supervisor Menu.
Enter the password, select System Parameters, and then select Download Method.
Select IBMEFT or NCREFT.
7. Press [Can] to return to the System Parameters menu, and then select Download
Port. Select the correct download port and correct communication type.
