Post by MikeJames »

Hi,

Is the PicoConnect 441 cable available in a 2 metre length?

Regards, Mike.

You can build one yourself quite easy.

for the 9 pin D connector
1 = Diff+
2 = Diff-
6 = GND
Between pin 3 and 4 Resistor 4k3 (for TA441 detection)

Thank Benno,

I measured the cable - there is 74 Ohms between 1 -> Diff+ and 2 -> Diff-, This might be some impedance matching going on...

Regards, Mike.
