Looks like a opportunity for somebody to venture into the commercial world with a "CONVERSION PLUG" for the K2??
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Don Wilhelm Sent: Sunday, October 23, 2005 18:34 To: Stewart Baker; Jim; Elecraft Reflector Subject: RE: [Elecraft] MicroHam microkeyer Stewart and all, That is precisely why I hesitate to refer to the DE9 connector on the KIO2 and the KPA100 as an 'RS232' connector. To those not yet informed, please be aware that connecting a standard RS232 serial cable to this K2 connector (and the other end to a computer) will most certainly do harm to your K2. This connector carries K2 control signals (non-RS232) as well as the RS232 signals (only TXD and RXD and Signal Ground are RS232 standard levels). The connector itself does not follow the RS232 standard - perhaps it would have been better implemented as a DIN connector, but it is too late for that now. There are only 3 pins (OK, 4 if you include frame ground on pin 1) that are RS232 signals. The rest of the pins should not be subjected to the up-to plus/minus 25 volts levels that may be present should the other end of the cable be connected to a device which presents standard RS232 signals. For my own K2, I have put a plug into pin 4 and broken off pin 4 of the mating cable, so only that special cable can be plugged into the K2 to prevent an accident that can happen to the best of us. 73, Don W3FPR > -----Original Message----- > > It seems to have the ability to send commands to the K2 via the > serial port. > What I meant to have said, was that Elecraft have some fairly non > standard usage > of the pins on a RS232 D type. > > 73 > Stewart G3RXQ > _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
