Engine ID A/B indicators, Power ON/OFF switch

A ENGINE ID A/B indicators

These indicators indicate whether the DSP1D/ DSP1D-EX is connected to the engine A or engine B channel.

Indicator A lights up if the DSP1D/DSP1D-EX is con- nected to the engine A channel jacks of the CS1D con- trol surface (DIGITAL I/O jack A and CONTROL I/O jack A). Indicator B lights up if the DSP1D/DSP1D- EX is connected to the engine B channel jacks of the CS1D control surface (DIGITAL I/O jack B and CON- TROL I/O jack B).

Error indication

•If both ENGINE ID A and B indicators are ﬂash- ing:

→There is a malfunction in the internal board (PDB, GDB, IDB1/2, EDB, EMB, or CIB). Or the necessary board does not exist.

•If either ENGINE ID A or B indicator is ﬂashing:

→During the Mirror mode operation, the ENGINE ID indicator for the unused DSP1D/ DSP1D-EX ﬂashes, indicating that the unit is in standby mode.

→If Indicator A is ﬂashing, unit A is in standby mode. If Indicator B is ﬂashing, unit B is in standby mode.

B CONTROL I/O 1/2 indicators

These indicators indicate which one of two CON- SOLE 1, 2 IN/OUT jacks (8) on the rear panel is cur- rently effective.

Note:

When you turn on the power to the DSP1D/ DSP1D-EX and the CS1D, and communication between the DSP1D/DSP1D-EX and the CS1D is established, one of these two indicators lights up. If neither one lights up, check the connection of the CONSOLE 1, 2 IN OUT jacks on the rear panel.

Error indication

•If the CONTROL I/O 1 indicator is ﬂashing:

→Communication between the CS1D control surface and the DSP1D is not established.The CONSOLE 1, 2 IN OUT jacks or the PC CON- TROL port is not connected correctly.

C INPUT CONFIGURATION 48CH/96CH indicators

These indicators indicate how many input channels are currently available. On the DSP1D, the 48CH indicator lights up. On the DSP1D-EX, the 96CH indicator lights up.

Error indication

•If the INPUT CONFIGURATION 48CH is ﬂashing:

→ The signal is not locking to the word clock.

D POWER ON/OFF switch

Use this switch to turn the power to the DSP1D/ DSP1D-EX on or off. When the power is turned on, the indicators 1 - 3 light up.

E MIDI IN/OUT/THRU connectors

These connectors are used to transmit and receive Program change messages, MMC, and other MIDI messages among external MIDI devices.

F PC CONTROL RS-232-C/USB ports

Connect these ports to a PC that runs Windows 95 or Windows 98 to control the PM1D system from the PC. Use a D-sub, 9-pin cross cable (female to female) to connect the RS-232-C port to the serial (COM) port on the PC. The USB port is provided for future system expansion, but it is not operative in the current software version.

G WORD CLOCK IN jack, 75 Ω ON/OFF switch, and WORD CLOCK OUT jack

The WORD CLOCK IN jack is used to provide word clock to the PM1D system from the connected exter- nal device, such as a clock generator. Use the WORD CLOCK OUT jack to provide the word clock to the connected external device from the PM1D. Use a BNC cable with an impedance of 75 Ω for the WORD CLOCK IN/OUT jacks.

The WORD CLOCK ON/OFF switch is used to termi- nate the word clock connection. Basically, if the DSP1D/DSP1D-EX is the last device of the word clock chain, or if nothing is connected to the WORD CLOCK IN/OUT jacks, set this switch to ON.

H CONSOLE 1, 2 IN/OUT jacks

These jacks are connected to the CONTROL I/O CONSOLE jacks of the CS1D control surface to trans- mit or receive control signals. For connection, use a genuine Yamaha cable or a BNC cable with an imped- ance of 50 Ω.

I REMOTE RS-422 connector

This D-sub 9-pin connector is used to control a con- nected tape recorder or a hard disk recorder. Serial commands can be transmitted through this connector to play or stop such a recorder.

This connector is provided for future system expan- sion, but it is not operative in the current software version.

J GPI connector

This connector is used to connect an external device that supports GPI (General Purpose Interface), such as a video editor to control the external device from the PM1D system or to perform certain functions of the PM1D system while controlling from the external device. You can connect a custom-made external switch here.

This connector is provided for future system expan- sion, but it is not operative in the current software version.
