OPERATION AND CONFIGURATION
Data acquisition system ALMEMO
trols; it is operated mainly via a PC.
9.1 Combination key
The first function of the one and only key ON/OFF-START/STOP (2e) on the mas-
ter measuring circuit board has already been described in Section 6.5.
Press to switch ON and press and hold down to switch OFF again.
If the device is on and a cycle has been programmed the same key can be
used to start and stop a measuring operation.
The current operating status is clearly shown by the LEDs.
9.2 Status LEDs
The following LEDs (3) report the device status :
ON
ON flashes once briefly
START continuous
COM continuous
COM flashes
REC continuous
REC flashes
START flashes once briefly Once-only measuring point scan from PC
COM flashes once briefly
REC flashes once briefly
ALARM
ALARM flashes once briefly Device supply voltage too low
9.3 Device address and networking
ALMEMO ® 5690-1M systems, like all ALMEMO ® devices, can also be net-
worked. To communicate with networked devices it is absolutely indispensable
that each device should have its own dedicated address; this is because only
one device should respond per command. Before each network operation
therefore all measuring instruments must be set, by means of their code
switches (1), to different device numbers.
Example:
Module address 01
In network operation consecutive numbers between 01 and 99
should be used; this ensures that device 00 is not addressed un-
®
5690-1M has only a few operating con-
