Why is there no 12 VDC on pin 1 on the auxiliary port in my AS950 sampler?
Summary
AS950 auxiliary port pin 1 details
Answer
On some older AS950 samplers, a firmware update is required to activate the power to pin 1 on the auxiliary port. This firmware update is available through the latest FSDATA file on Hach.com. Connect the sampler to your computer using a USB-A to USB-A cable and update the firmware on the sampler. If the sampler already has been updated, then there could have been a surge on the auxiliary port, this can cause an internal overload to be triggered. You can reset this by removing power from the controller for 10 seconds and the reconnecting power.
