I don't know what the FL7000 requires, but it can probably be produced simply from the Accessory connector.
From: "FISCHER,GREG" <[EMAIL PROTECTED]> Date: Wed, 09 May 2007 08:07:12 -0500 Hi Raj. This is from the FAQ page: Do I need the KRC2 option for my future K3 to band switch my non-Elecraft amp automatically? At least initially. We may provide other popular control protocols later. Note pins 3, 9, 13, and 14 on the Accessory connector. This means you DON'T NEED the KRC2 for many purposes. For instance, I want to have my IC2KL follow the band switching on my K3. The KRC2 doesn't provide the necessary voltage level signal without external components but a simple MUX and resistor network connected to those four pins on the K3 will do that. Many setups actually use BCD encoded band signals, just like the K3 supplies. The KRC2 is necessary for the K2, since the only band data is on the AUXBUS, but it's probably not necessary for the K3 for most uses. 73, doug >From the FAQ: >What is the pin-out for the DE-15 Accessory connector? >1 - DIG0 FSK? software definable TTL digital input (5V MAX!) >2 - AUXBUS >3 - BAND 1 Output (TTL) >4 - PTT input (in parallel with MIC jack PTT ) >5 - COMMON (via 100 uH choke) >6 - DIG Out 0 (software definable TTL digital output) >7 - DIG1 Input software definable TTL digital input (5V MAX!) >8 - POWER (pull to ground with open collector or switch to turn K3 ON) >9 - BAND 2 Output (TTL) >10 - KEY input (in parallel with KEY jack on rear apron) >11 - DIG Out 1 (software definable TTL digital output) >12 - COMMON (via 100 uH choke) >13 - BAND 0 Output (TTL) >14 - BAND 3 Output (TTL) >15 - ALC input (0 to +5V MAX) _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
