I have a Flex 6500 and an Expert 1k-fa, I have been trying to figure out how to connect the Flex to the 1k.I am using
a laptop to run the 6500 hundred which works very well barefoot. The laptop
hasnt got a D connector so I have purchased a usb to 9 pin converter and woder what other cables are need and the connections?.I am a dummy when to comes to computers so any help pic’s or
links etc. would be very helpful.
Search this forum and you'll find a few posts on this.
In general the solution is the usb-serial adapter you have plus a program called DDUTIL. DDUTIL will connect to your 6500 and will manage the expert bandswitching AND power settings for you.
If that is overwhelming or you do not want the complexity, the expert linears will band follow. This means all you need for your connection is:
Coax for RF input
Phono plug for TX relay
In this mode you would enable TX1 (or whatever port on your 6500 you want) to close when TX. Then when band changing you MUST keep your power initially down to about 3-5 watts and give a carrier and the amp will band switch. Then you can increase your 6500 power.
I have a 1k and 6300. Generally your 6500 power will be 20 watts or less to get full output on the 1k.
Of course in the band follow simple mode you'd use the front panel of the 1k to set half/full power and to enable or standby the amp.
If you use DDUTIL this is all handled in the DDUTIL program. All those controls are right there so you never have to touch your amp. DDUTIL can even turn it on/off for you.

Configuration is actually incredibly simple. The amp only requires a single RS232 connection to your computer (running DDUtil) and the wiring is straight-through so a standard null-modem type cable won't work (I assume it is wired this way as the amp is considered a DCE device?). As a minimum you need RXD/TXD/GND and DTR connected (DTR is used to power on/off the 1K-FA)
Once you have the cable connected, the CAT type MUST be set to RS232 (not Flex or Kenwood like I have seen on other instructions). You then just need to enable the SPE amp and select 1k and the serial port that you connected in DDUtil.
You will know if it worked as the Temp and other settings will be updated in the SPE 1K window within DDUtil. If this hasn't worked then check that the cable is wired correctly.
Bandswitching is also achieved through this single connection so there is no need to connect anything to either of the 15-way CAT ports on the 1K-FA.
You don't need to configure anything under RCPs or Passive Listener which is what confused me as some instructions say you do. I have full control of my 1K-FA with full bandswitching.
It is also worth configuring AutoDrive as these settings stop you over-driving the amp.
For those with the 1.2 K or the 2 K, this adjustment from the amp is not available.
Option 1: Serial CAT using RS232 Voltages use SPE DB15M Pins 1 RX, 9 TX and 4 GND
Option 2: Serial CAT using TTL Voltages use SPE DB15M Pins 10 RX, 3 TX and 4 GND
From your description you need to use option 1, your 1K manual diagram 12.6 shows this. Where it states radio connector substitute your USB to Serial device.
Consult the Pin out of your device. DB9 Male 2-RX, 3-TX, 5-GND
So SPE Pin1 to DB9 Pin3; SPE Pin9 to DB9 Pin2; SPE Pin4 to DB9 Pin5
Then configure SmartSDR CAT program for serial port for your USB to RS232 device, select CAT mode.
Serial port settings 9600 N 8 1
Set amp to Flex Radio CAT mode and adjust power levels for each band. Chapter 18.22 in the manual.
