Control of the camera

5. 

Introduction

5.1 

The Quartz cameras are fully software controlled via the Camera Link serial channel using a simple 
ASCII based protocol.

It is possible to save settings as ‘power-up default settings’ in the camera.

A command line control application is available to interactively control the camera settings. 
Please contact your local Business Office to obtain a copy of the latest release.

Although this is an easy way of changing camera settings, it is also possible to communicate with the 
camera using self deployed software. Please refer to

 

chapter 5.2

 

for the communication protocol. 

Use chapters 6 to 10

 as a detailed reference of the control commands. 

Communication protocol

5.2 

The camera is controlled by a host system connected to the Camera Link interface using the serial 
communication link of the Camera Link. Commands and resulting data are transferred between the 
host system and the camera by means of a communication protocol. The host system is the master 
in the communication link. All actions are initiated by the host system.The camera only replies to a 
message received from the host system.

Data link settings

5.2.1. 

The data link settings that shall be used for communication with the camera are:

Baud rate 

57600 baud 

stop bit   

1 

data bit   

8 

parity 

 

none 

handsha king  none

Data flow characters

5.2.2. 

The communication protocol uses data flow control characters to identify a message and for 
acknowledgement.  
The following data flow characters are defined:

CHAR

DEC

DESCRIPTION

NUL

0

NUL character, is ignored

STX

64

start of message identifier

ETX

13

end of message identifier

ACK

6

positive acknowledgement

NAK

21

negative acknowledgement

Message Format

5.2.3. 

Command and data are packed in a message. A message starts with the STX character followed 
by the message content. The message ends with an ETX character. The characters allowed in the 
message content range from decimal 32 to 255. 
Format:  STX <message content> ETX
