PC Control Specification for VP-12S1
1. PC Control
Interface
* RS-232C(Straight Cable)
* Baud rate:..................................... 9600 bps
* Data length: .................................. 8 bits
* Parity: ........................................... None
* Stop bit:......................................... 1 bit
* Flow Control: ................................ RTS/CTS
* Communication procedure: .......... Full duplex
2. PC Control Command Reference
2.1. Command Communications Sequence
Projector returns ACK, NAK, or Status after reception of Command within 1 second.
An ASCII code is used f or data. It is discriminated wheth er transmitting character sequenc es are a capital
letter and a small letter.
Although there is no distinction of a capital letter small letter, let a capital letter be a standard.
Command transmission and Status reply add Start Character and End Character as follows.
Start Character : ’@’
End Character : 0x0D
Command Sample : "@PWR?", 0x0D (Request Power Status)
Feedback Sample : "@PWR1", 0x0D, 0x0A (Power Status = On)
ACK and NAK use the following control code.
ACK(Reception success) :0x06, 0x0D, 0x0A
NAK(Reception failure) :0x15, 0x0D, 0x0A
A reception side cancels data before '@'. W hen 0x0D comes, with '@' not com ing, NAK (recept ion failure) is
returned.
That which made Hex the ASCII code is used for transmission and reception of digital data.
Between a command and a numerical value, '/' is inserted as a delimiter.
For Example: When 26(decimal) of the number is expressed
'1', 'A'→ 0x31, 0x41
2.2. Normal Command
It is Command which demands processing.
In data other than an appointed command, or the state where '@' does not come, when 0x0D comes, it
becomes reception failure, and NAK is returned.

PC Control Specification for VP-12S1
Commands, such as P ower On Command at the t ime of notes Standby (Fan operation), return on ly ACK,
when processing is not carried out.
For example: When Power On is sent to Projector.
Command transmission from PC.
"@PWR", 0x0D
After Command processing end and from a projector to a reply
0x06, 0x0D, 0x0A (ACK reception success)
or 0x15, 0x0D, 0x0A (NAK reception failure)
2.3. Request Status Command
It is Command which demands Status.
Projector returns Status or NAK.
In data other than an appointed command, or the state where '@' does not come, when 0x0D comes, it
becomes reception failure, and NAK is returned.
For Example: When Power Status is requested to Projector.
Command transmission from PC.
"@PWR?", 0x0D
After Command processing end and from a projector to a reply
"@PWR1", 0x0D, 0x0A (Power On)
or "@PWR0", 0x0D, 0x0A (Standby)
or 0x15, 0x0D, 0x0A (NAK reception failure)

User Gamma Table rewriting command
It is the command which rewrites User Gamma Table which has three for R, G, and every B.
Commands are as follows.
"@UG/1/R"............. The command which rewrites R Table of User Gamma Table 1
"@UG/1/G"............. The command which rewrites G Table of User Gamma Table 1
"@UG/1/B"............. The command which rewrites B Table of User Gamma Table 1
"@UG/2/R"............. The command which rewrites R Table of User Gamma Table 2
"@UG/2/G"............. The command which rewrites G Table of User Gamma Table 2
"@UG/2/B"............. The command which rewrites B Table of User Gamma Table 2
"@UG/3/R"............. The command which rewrites R Table of User Gamma Table 3
"@UG/3/G"............. The command which rewrites G Table of User Gamma Table 3
"@UG/3/B"............. The command which rewrites B Table of User Gamma Table 3
Command forms are as follows. CR is "0x0d, 0x0A".
"@UG/1/R" CR // R Table rewriting of User Gamma Table1 is specified.
"0123" CR // ASCII (Hex) character describes Gamma value.
"4567" CR // If it is 0x4567, it will be described as "4567."
"89AB" CR // 512 value per command is transmitted.
"CDEF" CR // Check every one thing which Com Device completed transmission at the
time of transmission of gamma value.
"0123" CR
"Complete" CR // This character sequence is transmitted from VP12.
It is the command that reads User Gamma.
Commands are as follows
"@UG?/1/R" .......... The command which read R Table of User Gamma Table 1
Command forms are as follows
"@UG/1/R" CR // R Table reading of User Gamma Table1 is specified.
// The following is received from VP12
"0123" CR //
"4567" CR // If it is 0x4567, it will be described as "4567."
"89AB" CR // 512 value per command is received.
"0123" CR // The 512th word.
ASCII (Hex) character describes Gamma value.
