Sync Box AC-in Rack Mount I/O
From MCEWiki
- ACDCU(0-7)
- 8 TTL outputs. Carries a high/low signal that enables/disables the MCE AC/DC converter.
- MCE(0-7)
- 8 Fibre outputs. Carries a 50 MHz Manchester-encoded signal containing data packets, which include incremented sequence numbers. Programmable as two sets of 4 outputs with differently spaced data packets on each.
- RTS-DV
- TTL input. Detects falling edges from a Real-Time Sequencer (implemented by SCUBA2) which tells the Sync box when to tell the MCE's to collect data.
- OPTO-TTL
- TTL input, spare input to the command processor. ***Not currently used, and open for suggestions.
- RS232 RxTx
- TTL input and output, used to command the Sync Box from a PC.
- DV Spare 1
- TTL output. Carries a 5 MHz clock signal that is synchronous with DV Spare 2.
- DV Spare 2
- TTL output. Carries a 5 MHz data signal that is synchronized with DV Spare 1, and contains the same sequence numbers as the MCE(0-7) outputs. NOTE: This output only contains the DV info stream, but not the occurrences of Addr_Zero between DVs.
- Polarimeter
- TTL output. Carries a 5 MHz TTL signal that contains the same sequence numbers as the MCE(0-7) outputs.
- FTS
- TTL output. Carries a 5 MHz TTL signal that contains the same sequence numbers as the MCE(0-7) outputs.
- TTL-IN
- SMB TTL input, spare input to the FPGA. ***Not currently used, and open for suggestions.
- TTL-OUT
- SMB TTL output. Carries a 50 MHz clock signal.
- Power
- AC
