• Observe the blue “COM” LED on the control panel while executing OUT->CONFIGURE CHANNELS command - it should briefly light on. If there is no light blink - check the cable and port connections.

The new WFG600 uses a PC-standard modem cable pinout. A standard straight serial cable can be used here.

The WFG400 and some older versions of WFG500 used a Macintosh-standard printer cable pinout. Two cables were supplied with the instrument. Please use the supplied serial communication cable since a standard PC cable will not work.

If you use USB-to-serial converter please check the port number that was assigned and select it in the “Preferences” dialog (Windows computers).

If uncertain please contact Pendulum Instruments (send email to service@pendulum-instruments.com).

Mac: Change the serial port. The software rev 5.x is compiled for the “printer” port (the one with a printer symbol) as standard, and the software with suffix MP was compiled for the “modem” port (the one with a telephone symbol). Software rev 4.x (for WFG400) was compiled for the modem port.

USB-Mac: Newer Macintosh models do not have serial ports and an USB-serial converter or a serial port card has to be used (for example a Keyspan SXpro card). Typically, the Port#1 emulates the Mac printer port. If uncertain consult your Mac dealer or FLC Electronics AB.

  • “Time out” may also occur when running a very slow waveform since the system waits for the waveform to end. Confirm the “Keep waiting?” dialog to continue or press RESET button on the WFG600 to abort and reset the generator.
