And you are almost certainly have experienced my problems! Indeed! Can you solve this problem without using a laptop,Andy? Yes - two options: 1. Redesign your system such that its line interface isn't affected by a grounded serial link (this is obviously possible, otherwise no modem could ever work with a PC!) 2. Isolate the serial link. When I had this problem (it was years ago) we bought a few RS232 isolator modules and used them whenever we needed to plug in a PC - this obviously saves any design changes & additional costs in your system. We got them from Newbridge or something - they don't exist any more, but I'm sure there must be something similar out there; eg, http://www.maxim-ic.com/quick_view2.cfm/qv_pk/1310 |
