Hello, Sorry for the late answer, I came back from a short holiday now. Well, The motor controller's official name is Ursa Minor MC3. MC3 means: This is the third version of the motor controller. Originally it was developed for medium and heavy duty astronomical mounts. We tested it recently with a ...

Hello, The return of the ':t1' command is the actual counter value. It starts with the timer value and counts down to zero. One hint: Sending the :T1 with timer value nnnn='0000' will stop the actually running timer and set the status of contacts immediatelly to 'b'. The format of the command again:...

Hello, The TA Bluetooth interface (Ursa Minor Bluetooth interface version 2.) already has an AF triggering output. All of the two contacts of the jack socket are implemented and driven through two optocouplers. There is a command "X" to drive them. Command format: :X1n where n can be 0,1,2 or 3. The...

Hello Claude,

I can suggest you a third option:

I try to help Synta to improve their uploader program to work it with our bluetooth modules.
If we can do it, it should be the third (and hopefully the best) option.

The firmware can be checked with my Terminal program. Just send the :e1 command. Yes, it is not so user firendly, but it operates with Bluetooth and you can use it right now.
I'll make an easier to use program soon...

After the firmware upgraded, it looks: ":e1=020681"

Hello! I've made a test, the Merlin updated successfully. I used a FTDI based interface cable. Mine is similar than yours, but instead of 220 ohms, I use 470 ohms. I updated the merlin with program downloaded from Teleskop-Austria. After updated, the Merlin works well, I doesn't noticed the position...

Hopefully it goes...

My opinion is: Writing a utility to detect the firmware version is not necessary, because the Synta "Motor Controller Firmware Loader 1.10" can do this.

Hello, Synta (The manufacturer of Merlin) has made a uploader program to upgrade the firmware in Merlin. This can be done with new Merlins (Firmware version number greater then 2.0.0) for upgrading, you don't need to have Synta handcontroller. Unfortunatelly, Synta's program can operate only with se...

If the pic is locked nobody can backup the code from it. Some newest pic's has military grade code protection. Others has standard grade protection (like the pic in Merlin), but it is also very strong and safe. Locked Pic accepts only one command: full erase. It erases the whole content of the flash...

My opinion: Building a new electronics maybe not needed. The existing electronics in Merlins can be re-used. It has a L293 driver, two nice PIC microcontrollers etc... Just write a new firmware and reprogram the PICs. They can be reprogrammed as soldered into the circuit. Second idea: I've developed...

Hello Merliners, I have a workaround: Because all second movements are slow, we should insert very small "dummy" movements between the positionings. The new relative goto command (H) is well suited to do these small movements. The inserted dummy positionings will be the slow ones. Because they are v...

Hello, I"ve found a new Merlin command: "H" means relative goto. This command used by larger Synta mounts such as EQ6. I tried it with Merlin and it works. However, it didn't solve the slow movement problem. Using the H command: :L1 (Stop the motor) :G100 (G101 sets the opposite direction) :H1007000...

Hello,

At home I'll look inside the new Merlin and check the encoder discs, that they have the same number of teeth or not.
I also noticed the different sound and speed of yaw and pitch motors.

So, these are programmed goto movements, not normal jog commands. (Normal jog means, the free movement ...
