GPI / RS232 (input / output)
This rear-panel connector is a 10-pin male dual-in-line type. This allows for RS232
communication, GPI/O functionality, and provides On-Air status.
BALANCED AUDIO / AES / LTC (outputs)
This 30-pin multi-way connector provides outputs of Analogue Balanced Audio, AES
Audio, and LTCs.
GPS (input with +5v DC output to power antenna)
This coaxial connector is used to connect a suitable GPS aerial in order to be able to
genlock the CY460 Sync Pulse and Test Pattern Generator, and to provide accurate
time and date information.
1Hz (output)
This BNC provides an output of the 1Hz pulse derived from the incoming GPS
signal.
10MHz IN (input)
This BNC allows the user to supply a 10MHz reference from an external device.
10MHz (output)
This BNC provides an output of 10MHz derived from either the extremely stable
internal oscillator, or looped-through from the 10MHz IN. A relay controls which
signal is routed to this output.
WK/TTL1, WK/TTL2 & 6Hz/TTL3 (outputs)
These three BNCs each provide independent outputs of either Word Clock (on “1” or
“2”) or 6Hz (on “3”), or any one of a selection of traditional pulses, e.g. Mixed Sync,
Mixed Blanking, etc.
DARS (output)
This BNC provides an output of DARS (Digital Audio Reference Signal).
AES1 & AES2 (outputs)
These two BNCs provide outputs of the associated AES audio channels in serial
format
