Thanks,Muddog
Follow the link for that round connector used in the E-Z=GO adapter cable post I made earlier in this thread. Go to the source site and look at the similar connectors until you find the one used by Club Car. Those connectors come in a variety of contact numbers, keyway positions, and types of threads in the retaining ring. It can take me hours of comparisons to find a correct source for a connector. Very few manufacturers will reveal the brand and part number for a connector they use, as it provides security for their technology.

The EEPROM content of the interface is checked when you first install the software, and the software sets a flag in the Windows Registry with that as the highest access level. Once that is set, you can use a lower access level interface. So, if you hack your registry entries, you can access higher access levels.

I was unable to reveal this while I was bound by my NDA and contract. That is over now. I saved interface memory contents so that you can program this data into the EEPROM of an FTDI USB to Serial adapter. I gave the source links in earlier posts. Many of my files were lost in a HDD crash a few months ago, but most of the critical data was backed up. I just have to find which backup drive I backed the files up to. I wrote down the data on paper from an OEM interface. If you copy your registry entries with an invalid (unprogrammed) interface connected, then compare that to your registry entries after putting in a valid interface, you will see what changes are needed!

Here is the OEM data to program into your FTDI interface EEPROM:

0000: 0040 A11F C800 0000 8032 0800 0000 981A
0008: B234 E60E FFFF 0F00 1A03 4300 7500 7200
0010: 7400 6900 7300 2000 4900 6E00 7300 7400
0018: 2E00 3403 3100 3300 3000 3900 2000 5500
0020: 5300 4200 2000 3C00 2D00 3E00 2000 5300
0028: 6500 7200 6900 6100 6C00 2000 4300 6100
0030: 6200 6C00 6500 0E03 3000 3000 3000 3000
0038: 3000 3000 0000 44EB F660 39D7 0A02 A7DB
0040: 2304 DCFB 0000 2A3A CD28 4200 0000 0000
0048: 0000 0000 0000 0000 4941 5459 5531 4F37

Have fun!

Bob

which software? FT_prog?

For a newbie, is there an easy method to put the "the OEM data to program into your FTDI interface EEPROM" per the earlier posting with all the FTDI data listed? I am aware of the FTDI program called "FT_Prog" and can see the pre-existing EEPROM data set.

after install FT_Prog , can't see any registry about the access level ?

It's a few pages back in this thread. I'm short on time or I would look it up. It's about making programming cables.

The registry hack is for the Curtis software, not FT_Prog. FT_Prog is used to write the changes to the FTDI USB cable to make it emulate the dongle. There are other changes made as well, all discussed earlier in this thread. Such as inverting the TTL, ect.

I got it.

Hi, just wondering if you figured out how to accomplish OEM mode. Thanks!

Default Re: Programming Curtis Controller

Good afternoon.

Following is my Curtis programming experience. Maybe this is the wrong place to post this, as I'm not doing a gulf cart, but maybe some useful Curtis programming info? First, a bit about my project.

A friend of mine recently donated his electric Trimuter project to a worthy cause. ME! The Trimuter was a Mechanics Illustrated (or ?? magazine) plans built motor cycle. This one build as an electric version. The electric motor cycle project is almost complete, with mainly the electrical system to finish and a number of other minor issues yet. It is set up with a Datson differential fitted with a DC series wound 72 volt motor. Plans also calling out for a 60 volt system with this particular 72 volt motor.

Originally, the plans called for a switches/contractors motor control system. My plan is for a DC motor controller to drive the motor. My controller selection (already received) is a Curtis 1221M-6701 unit. I ordered it with default settings, figuring (hoping) it would be a small task to program it.

Using the 1314 PC programming software, my 1st attempt was with a USB cable, I used an old cell phone data cable. The cable has a box in the middle with the Prolific PL 2303(?) chip on it. A little research of the chip made it easy to ID the TX, RX and GRD wires. I rigged it up to the controller with a PC power supply MOLEX connector, but nothing. A visit back here and I find that I was not powering the KSI input. Hooked back up and I still could not connect. With Windoze Hyperterminal, I could see I was receiving from the controller as on screen, the controller was sending a 2-1 code. That which I was seeing was just the cursor blinking and moving over one place twice, pause, then moving one place. Longer pause then 2-1 again. Code 21 made since as my series 9v transistor batteries powering the Curtis was down to about 50 volts at this point and the controller was still set at 72 volts. I did a loopback test with my cable set up and that worked, just would not/could not connect to the controller.

I hesitated on hooking up directly to the serial port on back of my laptop as some stated the voltage might be too high, like 12 volts or too much for Curtis. In looking at the wiring diagrams for the Curtis, I see that you hook the +15 volt pin in the molex connector to the RX pin, if using an LED status indicator. I was confident enough that the serial port voltage likely would not hurt the RX input on Curtis.

Today, I made up a straight serial to molex cable. COMM port was set to 8,1,N and xon/xoff. With my (6) 9 volt transistor batteries snapped together in series to make a (now about) 46 volt battery pack. All hooked up again, the Curtis 1314 and laptop connected immediately using the "enhanced serial" protocol. Plain series protocol did not work.

I have a few more parameters to change, but my 1221M-6701 is now set for 60 volts and a parameter file saved for me to research a bit further.

Here are a couple thoughts I've had this week on some persons being able to connect and some not.

From the schematics, one hooks the RX pin to the 15v pin in the molex for an LED status indicator. I also see talk about different serial output voltages on different PCs/laptops.

Is it possible those not making connections have higher serial output volts, VS those that do connect have lower serial voltage? I wonder if the RX pin seeing a higher voltage, maybe it switches that TX pin to the LED status output mode. If a lower voltage comes in on the RX pin, it switches the molex connector to a communications port mode? Just a thought, maybe I'm way off course.

Anyway, that's my story as of now. If this should be posted elsewhere, please let me know.

Thank you and take care,
Dale
