It has come to our attention that some CBD-001 cables which we supplied in the past (connect PCD-001 digital only module to PC - NOT CBA-001 cables) may be of the 'null modem' variety. The effect of using such a cable is that under sustained/high throughput network activity Cortex will likely lose synchronicity with the PCD (because the handshaking is nulled), furthermore it will not be able to then automatically recover the PCD (because the reset control signal is also nulled).

We have contacted customers who we believe have received such cables from us, but if anyone reading this has been missed out please contact us with your details and we will send you a replacement.

Our apologies to anyone who may have experienced the symptoms in the meantime.
