Sony XC-555/555P technical manual Sequence from Power up to Beginning/End of Communication

Send a command from the host.

The Sequence from “Power up” to Beginning/End of Communication

Commands expressed in writing as alphabetic letters are always enclosed in brackets [ ], and Carriage Return is abbreviated. For example, what is written on the page as [12AB] is sent as 31h, 32h, 41h, 42h, and 0Dh in data.

1 Immediately after the power is turned on, the camera makes the required settings based on information stored in non-volatile memory, and the camera begins to start up.

At this point in time, RS-232C communication is not permitted.

2 After start-up is completed, the camera sends [ACTV] to the host.

After the host has received this [ACTV] transmission, send your commands to the camera.

3 Send the version confirmation command [VERS] from the host.

Based on this, the camera enters the RS-232C mode.

4 The camera sends its software version information [X1**] 1) and [OKAY]to the host.

1)[X] indicates that this is an XC series camera.

[1]is a product code that indicates this is an XC-555. A [2] would indicate an XC-555P.

[**]indicates the version of the software. [10] in place of

**would indicate Version 1.0.

5 After the [OKAY] is sent in step 4, the camera is able to receive setting change commands from the host, and it waits for communication.

7 The camera receives the command, and when execution is complete, it returns an [OKAY]. (For all commands except the One Push AWB command.)

If a receive error or a command error occurs, [CERR] is returned from the camera.

Do not send the next command from the host until an answering (Ack) [OKAY] or [CERR] is received from the camera.

RS-232C Command List

8 If you send a [STOP] from the host, the camera returns an [OKAY], then it exits the RS-232C mode and re-enters the normal operating mode. (That is, it returns to the state it was in after step 1, above.)
