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.)

4. COMMAND TYPES

The types of commands used can be divided into apply commands and reply commands. Both of these command types can be

further divided into setting commands, acquisition commands and initialization commands. Apply commands are used to make

settings, acquire information and carry out initialization, and reply commands provide responses to apply commands.

Figure 4-1. Apply/Reply Command

The table below gives details on each command.

Table 4-1. Details on each command

5. COMMAND STRUCTURE

• ECommands are expressed as hexadecimal codes.

• All commands start with an ID code and end with a checksum.

When an ESC/VP command which is sent from the computer is received by the projector, a reply is returned.

However, the replies which are returned by the projector only indicate whether the initial command was received by the projector,

and do not indicate whether the command was executed or not.

Acquisition commands are sent in order to check the execution of a command.

In addition, if the next command is sent before the reply to a previous command has been received from the projector, it may

result in a communication error.

The command structure is shown below. * The maximum length for a command is 1024

bytes.

* Command layout is BigEndian.

(1) STX

: 0x1D (1 byte)

(2) Size

: Size of a command packet (Specifies a number of the data from 1D to CS) (2 bytes)

Example) To turn the power on over a serial connection

Example) To check the power status over a serial connection

(3) Attribute

: Indicates attributes such as apply command/reply command, OK/Not OK, etc. (1 byte)

The attribute codes are shown below.

(1) STX (2) Size (3) Attribute (4) FromTo (5) Group (6) Item (7) Parameter (8) Check Sum

rectly.

rectly.

(7) Parameters

: Parameters differ for each command, so refer the separate descriptions for each command.

* In the case of items for which the setting range can be adjusted, the parameter values are the values in the table below

which have been converted to hexadecimal format.

* If a reply command contains an error attribute, the following parameter (2 bytes) is set.

(8) Checksum

: Represent checksum (1 byte)

Checksum calculation method

All bytes of data from the size to the parameters is added together, and the twos complement of the result in hexadecimal for-

mat is subtracted from 0x0100 to obtain the checksum.

Example) For the command "1D 0007 01 10 00 02 0A CS"
