Service cables for Victory Empulse TT

(1/3) > >>

new-brammo-guy:
I made the CANbus and RS485 connectors for my Victory Empulse TT. Both work well. The RS485 plugs in directly to the top and bottom battery modules (separately). The CANbus is on the front right side of the bike - there are other posts about this.

RS485:
I followed the directions in this post including downloading the LabView 32-bit runtime software (thanks hackshack and others!): https://brammoforum.com/index.php?topic=4051.msg29217#msg29217

The connector for the Victory Empulse is different from the Brammo Empulse though. For the Victory you need this connector:
Molex # 0334721201, Digi-Key Part Number WM4735-ND: https://www.digikey.com/en/products/detail/molex/0334721201/1756779?utm_medium=email&utm_source=oce&utm_campaign=4251_OCE22RT&utm_content=productdetail_US&utm_cid=2187578&so=77360835&mkt_tok=MDI4LVNYSy01MDcAAAGGTCKL2RlzhabBLOEiIsLzs_lhEMI3Vxg-_Ia8CBKh9ylSvHPfkZI6ZCj7bdtuiAX1XZu8LkAKEVgUbcTgIBGR3h6NXUiSu06YTvjBnabL

You'll also need this contacts: https://www.digikey.com/en/products/detail/molex/0330122022/3184799?utm_medium=email&utm_source=oce&utm_campaign=4251_OCE22RT&utm_content=productdetail_US&utm_cid=2187578&so=77360835&mkt_tok=MDI4LVNYSy01MDcAAAGGTCKL2RmGfzIUNrZ1RmXiPo-E3oCje1jDLz1YnAJS-DOJM70IYAYV512zlcm8jG2-jKHFwdg_lMg7W4MoG1FvFEiS7PWg5pZZAArf_VAe

Watch a quick youtube on how to load the contacts for Molex - will save yourself some frustration! Might want to buy a crimping tool too, though probably could get by w/out it. A paperclip works well for adding/removing the contacts.

For wiring (numbers are on back of the connector):
Pin 2: A+ (black)
Pin 3: B- (white)
Pin 5: +12v (blue, goes to power supply, see below)
Pin 6: Ground (orange, goes to both the USB dongle GND screw terminal and the power supply GND)
Pin 10 and Pin 12 are connected together with a brown wire (essentially grounding the interlock pin)

Note: all other pins are empty (i.e. Pin 1, 7,...) - don't need anything in those pin slots.

I needed a 12V power supply (blue wire, Pin 5) and used the same ground from the power supply as the connector ground (orange wire, Pin 6). See attached image.

For the USB to RS485 dongle (3.3v): https://www.waveshare.com/usb-to-rs232-485-ttl.htm
I also have this one and it worked too (and cheaper!): https://www.waveshare.com/usb-to-rs485.htm

See attached image of software running. Unfortunately I have errors (my bike is dead with B40, see other posts).

I also downloaded this Serial Port Monitor, which allowed me to see what was being sent and received over the RS485 line.

I'll post the CANbus connector and dongle details later, though it's the same as the Brammo Empulse which can be found on other posts. With the CANbus + IXXAT dongle, I updated the firmware for the VCU, etc. see here: https://brammoforum.com/index.php?topic=4240.msg29186#msg29186

I found the wiring for the RS485 from the Victory Service manual (attached)

A couple pics of my setup and Molex connector

Lennon, Nicely done!! I ordered my power supply today off ebay, same model. Also the the waveshare converter from amazon. thank you for posting this. I will be picking your brain when I get stumped. The picture you show in this posted shows empulse BPM1590 is that for the Brammo or the victory? I plan on connecting directly to the circuit board of each module.

new-brammo-guy:
Happy to help if I can. Definitely don't struggle too much with the connectors - you already have enough on your plate! The pictures above are from my Victory Empulse. I'm impressed how well the software works once I had the cables, drivers, etc.
