#156453 - If not straight wires Responding to: ???'s previous message |
Hello Forum
Thanx a lot - verry informative answers. In the mean time we have switched from 485 to 422 or from half to full duplex. I'll still go forsom Linear or Maxim driver with 15 kV ESD protection and at least 60 V accepted at the inputs. This is some peace of military gear, so I will try once more to convice the guy, that twisted pairs realy isnt up for discusion. Any of you girls or guys out there, that have an idea of a rugged cable with 3 twisted pairs of 1,5 mm2 with a shield? They would love it, if it is mil spec something or maybe have a NATO (spare)part number. regards Per |
