#140231 - have fun Responding to: ???'s previous message |
I do not consider myself 'the ultimate' J1708 specialist, but I have almost daily worked with this bus for 5+ years. I have yet to see ANY 'adapter' that does not have 'hiccups'. Usually when another device using an adapter is added to the bus by someone else all hell breaks lose. This, in some cases, is because the device attached to the adapter is trying to go beyond the limits of the adapter. In other cases it has been because of using an 'adapter' that is only a 'level converter' and 'ignoring' the protocol. The best adapter, in my experience (for testing purposes, I do not use adpters, my devices 'speak' J1708 natively) is the B&B HDV100A2. Whenever I need a PC on the bus I use that one and have seen no glitches when staying within its limits http://www.bb-elec.com/product.asp?sku=HDV100A2
