PESA offers two connector choices in dedicated input or dedicated output frames for single-ended or differential time code data signals. Each frame provides 64 time code data channels through either ELCO block style connectors or 6-pin pluggable style connectors. Each input or output connection through either connector type is available with both single-ended and differential signal connection points. Each time code signal occupies the routing capacity of two audio signals, therefore 64 input or output channels of time code data fill the 128 channel capacity of the frame. Time code data inputs must be routed to time code output frame channels. Time code will not pass through a standard audio output channel or audio frame. Each frame provides two power supply module slots. One power supply is required for frame operation; a second power supply may be added for power redundancy.
