Panasonic AG-MX70P manual External interfaces, ≥ Functions that can be controlled from the AG-A850

External interfaces

This unit comes with three connectors to support four external interfaces: a GPI input connector, RS-422A/RS-232 (9-pin) connector and a Tally output connector. Select the connector that suits the editing controller model used.

∫GPI (general purpose interface)

This enables the use of auto takes with the GPI output of the external controller. At the fall of the GPI signal, wipe/mix set on the panel or DSK or Fade is executed.

∫RS-422A

This enables the AG-A850 external editing controller to be connected to the unit and the VTR to be controlled from a remote location.

≥Functions that can be controlled from the AG-A850

±Wipe settings

±Mixing

±Auto take time and auto fade time settings

±Downstream key fade-in and fade-out

±Cross point source 1/source 2 (source 2/source 3 or source 3/source 4) switching

(Cross mode switching is performed by the RS- 422A/RS-232C selector switch on the rear panel. Support for the editing controller is shown below.)

≥Connections

1)Set the RS-422A/RS-232C selector switch to “RS-422A.”

2)Connect the connecting cable from the AG-A850 to the editing controller connector on this unit.

3)The pin layout of the editing controller connector is shown below.

5	4	3	2	1
	9	8	7	6
	Connector (9P)
Pin No				Signal
1			FRAME GROUND
2			TRANSMIT A
3				RECEIVE B
4			RECEIVE COMMON
5				SPARE
6		TRANSMIT COMMON
7			TRANSMIT B
8				RECEIVE A
9			FRAME GROUND

∫RS-232C

This enables the unit to be controlled using a personal computer. All of the unit’s functions with the exception of AUX 1 and AUX 2 can be set.

≥Connection of conversion cable

25-pin		9-pin
1	TXD	1	SPARE
3	RXD	2	RXD

5	CTS	4	DTR
6	DSR	5	SIG.G
7	SIG.G	6	DSR
20	DTR	9	SPARE
			[DCE CONNECTION]

Use the above conversion with the 9-pin straight cable as well.

<Notes> Editing using the RS-422A, RS-232 and GPI interface connectors

≥The commands are received and then executed 3 frames later.

≥If, while the 3D optional board is installed, the 1-Frame Dly mode has been selected by the system 1 settings (see page 56) on the “Setup” initial setting screen, the pictures and sound from the source are always output with a 1-frame delay.

≥When selecting a DVE pattern, set the transition time to more than 2 frames. No guarantees are made for frame accuracy if the time setting is lower than this.

∫Tally

This is the open connector for the tally lamp.
