Multiboard Electronics

The Multiboard electronics, sometimes referred to old electronics are usually used in the MKII and MKIV Brewers. Some of the earlier MKIII brewers may also be running the multiboard electronics. The multiboard electronics consist of the primary power supply¹ (PPS), secondary power supply, Card cage boards, and the heatsink.

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.

Card Cage

There are 7 cards that are needed for a brewer to be in operation. The following list is the order the boards are in from top to bottom.

IO Board (A)
IO Board (B)
IO Board (C)
Microprocessor/RCA board
Clock Board
Analog to Digital Board
Photon Counter Board

For Diagnostics purposes, the minimal amount of boards required to communicate to the brewer from a computer is just the Microprocessor/RCA board and the Photon Counter Board. All the other boards can be removed. This will help diagnose if there is a bad board causing communication issues.

HV - Refers to the new high voltage module (Ultravolt - 2AA24-P20-M) that is mounted to the heatsink
TP#xx - Refers to the test point bracket Pen-ray Relay - Refers to the external Pen-ray HG controller. This replaces the traditional mercury filament bulb with a pen-ray style mercury lamp.
Rate Meter (Pin 10) - Rate test points has been grounded off on the old SPS and left unused on the new SPS.
Pin 6, 14, 15 and 17 previously has no connection on the old SPS

FAQ

Q: What are the differences between new vs old temperature circuit on the clock board?
A: Note the resistors on the top left of the boards below (New Vs Old). New temperature circuits, some resistors has been replaced with a jumper wire.

Q: How do I find out what what LED sensor is active?
A: Depending on what you're looking for, you can use one of the 3 commands in MM GET,800GET,544GET,1056. This will yield the following

Bits	`GET,800`	`GET,544`	`GET,1056`
0	CW Switch Pressed	Slitmask @ 7
1	CCW Switch Pressed	Slitmask @ 0
2	CW AZ Sensor Blocked	Mic1 @ Max WL(Mirror side)
3	CCW AZ Sensor Blocked	Mic1 @ min WL(Bulkhead side)
4	ZE Sensor Blocked		Iris Fully open
5	FW3 Sensor Blocked(Mic2 @ Max wl in MKIII)	FW3 Sensor Blocked in MKIII	Iris Fully Open
6	Down Switch Pressed
7	Up Switch Pressed
