1. MAINS INPUT – IEC receptacle with an integral fuse and rocker switch.
2. AUX POWER – 12-pin connector for external backup CDC PSU 4800.
3. Cadac MegaCOMMS data – 4 x BNC connectors carrying all audio
and control data between the control surface (or MC Router) and the
stagebox. See “Connecting the hardware” on page 28 for full details.
4. Port status LEDs – one yellow and three green LEDs per port. In normal
operation one or more green LEDs per port should be illuminated; the
number will vary, and depends on the bandwidth in use. The yellow LED
flashes when no MegaCOMMS signal is present at the port. Unconnected
ports will have no indication on the corresponding LED bank.
5. Power rail status LEDs – four green LEDs, one per internal voltage rail
(18V, -18V, +48V, +12V). All must be lit for correct operation.
6. FPGAstat0 – red LED; used in factory testing only, should be unlit in
normal operation.
7. FPGAstat1 – red LED, illuminates to indicate loss of lock to the incoming
MegaCOMMS signal. Should be unlit in normal operation.
8. PICstat0 – red LED, flashes during power-on and firmware updates only.
If on otherwise, a boot failure is indicated.
9. Spare – red LED; not currently implemented
10. USB – type ‘A’ USB 2.0 port, used for firmware updates. NOTE: this port
is ONLY intended for the connection of memory sticks. Do not connect
any other type of USB device to this port.
11. BOOT SWITCH – for factory use only. Do not press.
12. Hex switch – set according to how the stagebox is being connected:
• Set to ‘1’ when connecting the stagebox to a CDC MC Router.
• Set to ‘2’ when connecting the stagebox to a CDC seven surface,
and it is to be used as RACK 1.
• Set to ‘3’ when connecting the stagebox to a CDC seven surface,
and it is to be used as RACK 2.
All other hex switch positions are unused.
