Template:Hierarchy header The MCE Control Computer (MCC) is a single board computer (Advantech PCI-7030) mated to one or two PCI fibre cards.
It is available in two form-factors:
- a 2U-high rackmount, 120-V AC-in configuration for ground-based experiments (known as the "2U MCC")
- a small form-factor (35×27×5cm) 18–36 V DC-in configuration for balloon experiments (known as the "small MCC")
We encourage it's use as a MCE controller for all experiments.
I/O
- Small MCC:
- 2U MCC back panel:
| A | PCI fibre card reset switch (unused) | J | RJ-45 1000-baseT Ethernet |
|---|---|---|---|
| B | PCI fibre card fibre receiver | K | VGA display port |
| C | PCI fibre card red light (fibre detect) | L | Reset switch (small MCC only; 2U MCC has equivalent on front panel) |
| D | PCI fibre card green light | M | Power LED (small MCC only; 2U MCC has equivalent on front panel) |
| E | PCI fibre card fibre transmitter | N | Power LED (small MCC only; 2U MCC has equivalent on front panel) |
| F | PCI fibre card DIO (unused) | O | 18-36 VDC Power in (small MCC only) |
| G | PS/2 keyboard port | P | 115V/60 Hz AC Power in (2U MCC only) |
| H | USB (x2) | Q | Mains Fuse (2U MCC only) |
| I | USB (x4) (optional: typically installed in 2U MCC but omitted from small MCC) | ||
The two form-factors have the same basic external connections with the following exceptions:
- the reset switch (#L), LEDs (#M, #N) and DC-in power connector (#O) on the PC panel are populated on small MCC panel but not on the 2U MCE back panel (a blank is installed in their place). The 2U MCC has a reset switch, LEDs and a power switch on the front panel (not shown in diagram)
- the 2U MCC has a 115V/60Hz HP-style power input and fuse on the back panel.
- Four of the six USB ports are optional (#I). They are typically not installed on a small MCC (simply for weight saving).
In MCCs with only one fibre card, typically Card #1 is missing, and the panel replaced with a blank.
Power
- The power consumption of a typical MCC is approximately 30-35 W (5 W less with only one fibre card).
- The 2U MCC, takes 115V/60Hz mains power over a 3-pin HP-style power connector. The small MCC requires 24-Volt nominal (18-36 V allowed) DC power in.
- The 2U MCC has a front panel power switch. The small MCC has no power switch: DC-in must be switched externally.
- The small MCE power connector is an Amphenol PTC-2A-14-5P. Positive voltage is on pins B and C. Return is on pins D and E.
