Single Board Electronics

The single board electronics, sometimes referred to new electronics are usually used in the MKIII Brewers. There's a very small numbers of MKIV brewers that may run a single board electronics. The single board electronics consist of the primary power supply¹ (PPS), lamp control board and the high voltage module. There are two version of the single board electronics, V1 and V2. See here for firmware programing instructions.

¹Note, both multiboard and single board electronics both have an PPS, however the multiboard uses a 24V/15V/5V power supply while the single board electronics uses 24V/12V/5V power supply. The latest brewer's produced by Kip and Zonen (around Brewer # 250) uses the TDK-Lambda NV175 series power supply. The single Electronics board uses NV1-4G5TT, where the multiboard uses the NV14G5FF.

Note 1: Top Refers to the connector on the stop of the ribbon connector stack on a V1 board when looking at it on a birds eye view. For V2 boards, it is the connector closer to the bottom of the board.
Note 2: From the table above, J2 is the connector on the top right of the board, and going left. J7 is on the bottom right of the board.
Note 3: [] indicates 12V pair and () indicates 24V pair and bold indicates jumper default

Commands

Frequency used commands in MM

Commanddescription
I,XResets motor X
?motor.ref.high[X]checks the reference flag of motor X on the high side
?motor.ref.low[X]checks the reference flag of motor X on the low side
?motor.address.[MOTOR]checks the motor address used for MOTOR

Changing Motor Address

The motor address can be changed in event of a bad motor driver or circuitry. This will require the ribbon cable to be physically moved to another connector as laid out here. Afterwards, enter MM or opmode in brewcmd.

USER
?motor.address[motorname] #This will output the current motor address number, verify this is the one you want to change
!motor.address[motorname] 7 #replace 7 with the actual address you'd like to change to
i,10 #replace the 10 with the original address, this will reinitialize the motor
save #once you verify everything is working as expected, you can save which will use up on of the save slots. #otherwise when the brewer restarts, it'll be using the original motor address.
Note: anything starting with # are meant to be comments and not actual commands
