Vmesnik

[S55G]

Ve kdo kje dobit oz. ma mogoče ker kje kakem v predalčku ..shemo vmesnika in kablovja za FT-51r (za ADMS-1e).
Nekaj sem že iskal (google) ampak kot zgleda do zdej neuspešno...

Hvala v naprej!

Tako...
nekaj smo le dobili....

Kolega Mark WB8URH mi je nedavno via email poslal shemo vmesnika tko,da ga kar tle objavljam če ga bo še ker nucal v prihodnje...

Moj je v izdelavi....

Mike,
Saw your need for information on FT51R data cable on eham.
Here is the schematic. Same as Ft11R/VX5R cable.
I just built one with discrete components. Works good.

The abbreviation NC means no connection. The DB9 connector can be Radio Shack part # 276-1538 or equivalent. A good place to start looking for the 4 conductor plug is Tower Electronics: 1-800-662-3422. The 2N2222 can be substituted for any general purpose NPN transistor, while the 2N3906 can also be substituted for any general purpose PNP transistor. D1,3,4 are general purpose silicon diodes. D2 is any 5.1V zener diode. All resistors are 1/4 or 1/8watt - 5% tolerence resistors. This PC programming cable can also be built with SMT (Surface Mount Technology) parts if desired.

The interface is a bidirectional level converter, changing TTL-level to RS232, and vice versa. The supply voltage comes from RTS, CTS and DTR, DSR and is stabilized with D2 to 5.1V with a zener diode. Q1 works as a simple switch, getting the data via R8 from the PC. In the opposite way Q2 drives the push pull stage Q6 and Q4. This cable works with the Yaesu FT-50, VX-1R, VX-5R. The cable can also be adapted to work with the FT-10 & FT-40 - which use a 3 conductor programming cable.

Namesto vseh teh tranzistorjev in uporov lahko uporabis 1/2 IC MC 1489. Drugo polovico lahko iskoristis za PTT in KEY z bolj pametno uporabo krmilnih signalov RTS in DTR. 5 V pri 10 mA se dobi iz radijske postaje. S54S in jaz sva pisala nadaljevanke o tem v CQ ZRS.

Ce imas voljo eksperimentirati, probaj najprej vezje z dvema tranistorjema: viewtopic.php?t=2368 Moralo bi delati tudi na FT-51.

OK.....bom poskusil....
