KIO3 Pinout
Locked
 
|
I have a question regarding the KIO3 layout. I'd like to abuse 3 pins for adding a GPS mouse to
my TrxPtc in the K3. According to the KIO3 description in the user manual Pin 1, 8,9 are not used. In the list of pins I am also missing Pin 7. I used Pin 9 as GPS VCC (5V), Pin 8 is GPS in and Pin 5 Ground. The Trxptc has GPS out - is there anything on Pin 7 of the K3 in the moment? Btw, the naming of RX and TX is "unusual" in the manual. I think a transmitting line is called TXD and a receiving line is called RXD, no matter on which device it is located. Data from the K3 = TXD -> RXD on the PC, Data from PC -TXD -> RXD on the K3.

From my professional experience TxD and RxD may be more common, but
RX and TX are used often enough that I would not call them unusual. Certainly using RX and TX should not cause any confusion. David K0LUM > > >Btw, the naming of RX and TX is "unusual" in the manual.

Werner,
If I recall correctly from my modem days -- The naming of RXD and TXD is correct for the K3 (it is incorrect for the K2) A DCE device (computer port for example) transmits on TXD and receives on RXD A DTE device (like the K3 or other terminal device) transmits on RXD and recieves from TXD. Yes, it is confusing, but the standard goes back *much* earlier than either the K2 or the K3. 73, Don W3FPR Dr. Werner Furlan wrote: > > Btw, the naming of RX and TX is "unusual" in the manual.

But Don W3FPR enlightened me that this is correct because the K3 is a Terminal Device and transmits on RXD, where the DCE device (computer) is receiving on RXD and transmits on TXD. > >Btw, the naming of RX and TX is "unusual" in the manual.

btw,
does anybody know the answer to my initial question: what about Pin 7 on the K3IO serial connector? Is it used or unused? It is not mentioned in my manual, neither in the unused pins (1, 8, 9) nor in the list of used pins. 73! de Werner OE9FWV |

The schematic diagram (on the Elecraft web site) shows the KIO3's serial
connector pin 7 is RTS_IN. According to the schematic, pin 2 is RxD out, pin 3 is TxD in, pin 4 is DTR in, pin 5 is "common" (connected through a small choke to ground), pin 7 is RTS in, and the remaining DE9 pins are not connected. The schematics are available from the Elecraft manual download page, http://www.elecraft.com/K2_Manual_Download_Page.htm. The direct URL for the schematic file (readable with Adobe Reader) is http://www.elecraft.com/manual/K3_Schematics_Oct2008.pdf 73 de Dick, K6KR -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of oe9fwv Sent: Tuesday, October 20, 2009 9:13 AM To: [hidden email] Subject: Re: [Elecraft] [K3] KIO3 Pinout btw, does anybody know the answer to my initial question: what about Pin 7 on the K3IO serial connector?

hi Dick and all who responded,

In my printed manual from 2007 there is a mistake which was corrected in the meantime. There is RTS listed as Pin 6 instead of Pin 7 and the unused Pin 6 is missing in the list of unused Pins. 73! de Werner OE9FWV -- If god can be god, why couldn't I?
