serial port remote control of K2 question
Locked

hi all,
has anybody already connected a Bluetooth CTR Interface to the serial port of the K2? What are the voltage levels needed? RS232 or TTL? FYI, the CTR Interface page is here: http://www.lynovation.com/ 73! de Werner OE9FWV -- Powered by Pegasus Mail - free at <http://www.pmail.com> Homepage: <http://www.qsl.net/oe9fwv> Email -> SMS:<+[hidden email]> _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

This question gives me cause to post my occasional RANT for the protection
of your K2. CAUTION! Be Aware - your K2 can be damaged by connecting some of the RS-232 signals. The K2 AUX IO port is NOT an RS232 port! Although the port has 3 pins that are compatible with RS-232 levels (RXD, TXD, and Signal Ground), there are other signals present on that connector which are for passing information to other Elecraft devices, and if these lines are subjected to the +/- 15 volt or greater voltages that may appear in an RS-232 interface, circuits inside the K2 may be damaged. Read the label on that K2 connector literally, it is properly labeled 'AUX IO', and that does not mean RS-232. It is unfortunate that the PC world uses these DE9 connectors for RS-232, and it is (was) a PC world implementation only, real RS-232 ports use the DB9 or the RJ45 connectors - these are defined in the RS-232 standard, the DE9 connector is not in the latest standard publication that I am aware of. 73, Don W3FPR > -----Original Message----- > > has anybody already connected a Bluetooth CTR Interface to the > serial port > of the K2?

Upon looking at the various pages you referred to, it appears that they have
made the proper adaptor for use with the K2. You would, however, need the KIO2 for this to work. Elecraft does not recommend a direct connection to the /K2 TX, /K2 RX lines as this could cause problems. As to the other questions, IF you have the KIO2, the KIO2 will interface WITH the Recommended adapter cable to a PC and uses +/- 15 (approximately) volt signals on pins 2/3 with 5 as common/signal ground (standard PC I/O). ALL other pins must have no connection!!! (or you will brake the K2 and possibly the K2 MCU. For most S/W to talk to the K2 it is assumed that pins 7 and 8 are tied together at the cable. I would address your questions to WWW Lynovation Com and ask them what is needed.

If you specified you are using with the K2 there is a specific adapter and
no cable is necessary. The cable converts from Yaesu, in my case to the K2 pin-out directly.

Werner, I have the CTR device and it works very nicely. I am using the
trick is to get the mating with the pocket PC device. I used the directions available on the internet. I really like having the logging, DX cluster and all on a handheld device which allows me significant freedom.

I also have the Yaesu Interface, so there is only an adapter needed? where is the voltage supply coming from? External or from the K2? 73! de Werner OE9FWV -- Powered by Pegasus Mail - free at <http://www.pmail.com> Homepage: <http://www.qsl.net/oe9fwv> Email -> SMS:<+[hidden email]> _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Nick,
That is the implementation I have chosen for protection against accidents, YMMV. The hardest part of accomplishing that is removing the male #4 pin from the mating connector. Actually I can understand little advantage in using a non-conductor, a chunk of wire works fine too, but certainly a toothpick works just as well. For those who do not understand Nick's comment, this is one method of keying the AUX IO connector on the K2 - simply put a block in pin 4 of the connector mounted on the K2 (or KPA100) and remove pin #4 from the mating connector. This prevents plugging in a cable with an unmodified connector. There are other methods of accomplishing the keying that involve modifying the connector shell - cut a notch in the male connector and solder a projecting wire on the female. 73, Don W3FPR > -----Original Message----- > > > Don Wilhelm wrote: > > CAUTION!

There is no DB-9. ITYM DB-25, but that wasn't specified in RS-232 - it was added with RS-232C. Prior to that the standard merely called for an unspecified 25 pin connector. What was once RS-232 was replaced by EIA/TIA-232, which in turn was succeeded by ANSI/EIA/TIA-723-1998 "High Speed 232 Type DTE/DCE Interface," which is active and current. The standard says the DE-9 interface shall be referred to as "ANSI/EIA/TIA-723 Alt B." In addition to the regular DB-25, there is also a 26 pin "Alt A." _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
