10 Interfaces and Options
10.1 Optical (infrared) interface
For communication with the optical interface an optocoupler and the “Device Monitor” software are necessary.
The optocoupler and “Device Monitor” are available as accessory equipment.
The optical infrared interface will be activated by automatically sending a header (according to EN 13757-3). Baud
rate: 2400 baud.
Then you can communicate with the meter for 4 seconds. After every valid communication the meter is open for
another 4 seconds. Afterwards the display is deactivated.
The number of read-outs per day via the optical interface is limited. During daily read-out at least 4
communications are possible. If read-outs are carried out more rarely, the possible number of communications will
increase.
10.2 Retrofitting with an additional communication interface (optional)
We also offer a retrofittable meter to which communication interfaces can be added later. You will find the
description of our optional interfaces in the operating instructions „Communication Interfaces S3(C)“.
To retrofit such a meter with an additional communication interface the calculator´s adhesive seal has to be
destroyed and the device´s calculator to be opened.
When the calculator is open please observe the ESD
requirements according to EN 61340-5-1.
Use a screwdriver with a wide tip (4 - 5 mm) and carefully press in the two round predetermined breaking points
above the cable feedthroughs (see picture 1).
