RS-232C Command List
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.
6 Send a command from the host.
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.
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.)
