#162592 - Not exactly but as per requirement Responding to: ???'s previous message |
Per Westermark said:
Are you saying that the termination resistors should only be used when using a very long cable and experience noise on that long cable???
That sounds like a very random rule. Not exactly , If the link is slower and short distance or in clean environ ment home/office etc termination wont be required and also we can save power. -Ap Oh as you didnt quote the entire , I just read and edited the typo please see here ; http://www.8052.com/forum/read/162589 |
