Command with Address Specification

10.1. Overview

- Commands with address are used to remote control more than one projector through RS-232C by
a computer.
- The command with address is defined as a single command per line that starts with "A" and ends
with carriage return (0x0D).
- When a projector receives carriage return (0x0D), it starts decoding.
- The address such as "A001" is prefixed to the Basic Serial Command or Expand Serial Command
already mentioned.
e.g.) Functional Execution Command: "A001C05" [CR]
e.g.) Status Read Command: "A001CR0" [CR]
- Projector has the function to set up its own address in Service mode.
Initial setting value is "No.001"
Available range of the value is "001" to "999"
- It clears the data in the receive buffer in the following cases.
0û
When receiving LF (0x0A) or EOF (0x1A)
0û When it takes more than one second to receive a single command.
(Until receiving carriage return after the reception of the first data)
- It returns the response within 60ms.

10.2. Functional Execution Command with address

10.2.1. Format

1) PC issues a command in the format below:
"A" Address "C" Command [CR]
"A" Address "CF_" Command "_" Parameter [CR]
Address: 3-digit number ("001" – "999")
Command: string (Refer to Basic and Expand Serial Command)
2) The only projector with the appropriate address decodes the received command, and
when it is ready to receive the next command, it returns the response.
[ACK] [CR]: When receiving Functional Execution Command (0x06, 0x0D)
" – " [CR]: When the received data cannot be decoded
However, when the address is "FFF", the projector executes the function but does not
return the response.
or
Commands with "FFF" as the address are valid to all projectors.
