INSTALLATION AND CONNECTIONS
The TDC-100 consists of two pieces: the rack-mounted electronics frame (1RU) and
the control panel. They are interconnected by the supplied 9-conductor cable, which
provides data communications between the two, and power from the frame to the
control panel.
All other connections are made to the electronics frame. The connectors on this
frame are:
DEVICE A
- port for disk or vtr A. Standard RS-422 (Sony 9-pin) format
DEVICE B
DEVICE C
DEVICE D
- same as above for devices B, C, D.
P-BUS IN
- P-bus II connection to production switcher - 38.4K Baud
P-BUS LOOP
- Pin-to-pin looping connection to P-Bus IN connector for
extending P-bus connections to other devices.
CONTROL PANEL - Connection to TDC-100 Control Panel (special cable)
RS-232 / GPI
- RS-232 port for PC upload/download of register data, and
GPI input and output connections.
EXT REF IN
- Looping BNC connectors for reference (analog) video.
This reference is required for accurate control.
POWER
- 95-250 volts, 50/60 Hz. Power consumption is <10W
GPI INPUT CONNECTIONS
The GPI inputs can be enabled in the menu, and have the following fixed
assignments:
GPI 0 - Stop
GPI 1 - Play
GPI 2 - Recue
GPI 3 - Recall Register 000
GPI 4 - Recall Register 001
Electrically, the inputs are a 74HC - series input (will accept ‘TTL’ levels), pulled up
to +5 volts with a 4.7K resistor. These should be pulled to ground to activate, with
either an open-collector or TTL output, or a dry relay closure.
DO NOT apply external voltage greater than +5 volts to the GPI inputs, or
permanent damage may result.
