ESC/VP Level 6 Serial Communication Manual (Abridged Edition)

3. SERIAL COMMUNICATION SPECIFICATIONS

The projectors can be controlled by connecting a serial cable to the projector (Mouse/Com port) and a computer so that ESC/VP commands can be sent from the computer to the projector.

[Communication Conditions]

• Communication Speed

Standard speed: 9600 bps (EMP-8100/9100/8150/7700: 9600 to 57600 bps)

 

(EMP-7600/5600: 9600 to 38400 bps)

• Bit length

8 bit

• Parity

None

• Stop bit

1 bit

• Flow control

Hardware (DTR/DSR)

[Connectors]

Connector type: D-sub 9pin

(The pins which are actually used are the five pins from 2 to 6. These pins are used to send and receive data, for flow control and for grounding.)
