Siemens Protool / TP270

[cjd1965]

Hi
I have been asked to go to a customers at short notice to do some basic mods to a TP270. Unfortunatley our RS232-MPI adaptor is at another site with another engineer.

Can I simply use a null modem cable directly from my laptop to the TP270 into the IF port? This would be my preferred alternative method.

I realise I will have to change settings etc.

Alternatively I could buy a USB host cable from a local PC shop but i think the firmware of the TP270 is very old so maybe an issue.

A null modem cable will work fine, pins 2-3, 3-2 & 5-5 should be connected on both ends of the cable to establish communication.
