Interfaces and Options
7.1
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 calculator for 4 seconds. After every valid communication the calculator 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
