Line driver IC | | 01/01/70 00:00 |
Telephone lines? | | 01/01/70 00:00 |
Slower analog solution.. | | 01/01/70 00:00 |
That's a job for a transfomer! | | 01/01/70 00:00 |
line driver | | 01/01/70 00:00 |
Missing the point | | 01/01/70 00:00 |
Eh?? What is | | 01/01/70 00:00 |
Modem? | | 01/01/70 00:00 |
Think Telco even if it's not | | 01/01/70 00:00 |
Have you read the datasheet? | | 01/01/70 00:00 |
Not the modem speed | | 01/01/70 00:00 |
What datasheet?????? | | 01/01/70 00:00 |
That is the datasheet | | 01/01/70 00:00 |
I mentioned the chips and you say I havnt | | 01/01/70 00:00 |
No, you don't | | 01/01/70 00:00 |
Xformer only | | 01/01/70 00:00 |
at this low data rate (9600 bps) he could use AMI | | 01/01/70 00:00 |
AMI protocol | | 01/01/70 00:00 |
who said anything about protocol? | | 01/01/70 00:00 |
Difficult and with few software options | | 01/01/70 00:00 |
Nobody said anything about a protocol | | 01/01/70 00:00 |
Getting ahead of the questions | | 01/01/70 00:00 |
fact is ... we don't have the information ... | | 01/01/70 00:00 |
Spare wire is already there . We do not | | 01/01/70 00:00 |
Getting ahead of the questions | | 01/01/70 00:00 |
What type of wire and what environment? | | 01/01/70 00:00 |
please stop this mistreatment of a word | | 01/01/70 00:00 |
A Protocol is a set of guidelines or rules. | | 01/01/70 00:00 |
Apologies , I meant CODEC nor protocols | | 01/01/70 00:00 |
I am not sure... | | 01/01/70 00:00 |
27 or more solutions exist ... | | 01/01/70 00:00 |
~9600bps | | 01/01/70 00:00 |
9600 is tough at that distance, so | | 01/01/70 00:00 |
Tough? | | 01/01/70 00:00 |
Not Tough? but costly. | | 01/01/70 00:00 |
Still missing the point | | 01/01/70 00:00 |
He did specify the data rate | | 01/01/70 00:00 |
Where to apply modulation schemes when | | 01/01/70 00:00 |
Oh yes you have! | | 01/01/70 00:00 |
Driver/interface | | 01/01/70 00:00 |
no | | 01/01/70 00:00 |
Maxim Preemph RS-422 driver | | 01/01/70 00:00 |
FEET | | 01/01/70 00:00 |
speed and distance still apply | | 01/01/70 00:00 |
a pretty fancy rf link would fit the cable budget | | 01/01/70 00:00 |
Reverse engineer these | | 01/01/70 00:00 |
Reverse engineer these | | 01/01/70 00:00 |
buy one and find out | | 01/01/70 00:00 |
Seems simple enough! | | 01/01/70 00:00 |
Why not | | 01/01/70 00:00 |
No black (box) magic methinks | | 01/01/70 00:00 |
an other blackbox | | 01/01/70 00:00 |

Have you ever heard of the teletype? | | 01/01/70 00:00 |
