Fig. 6 Signal profile
The signals at the 8 data inputs are transformed into a serial telegram with a parity
bit and an address, and transmitted.
With the positive flank of the TX signal, the waiting data is taken over by the inputs
and transmitted. The transmit signal must be applied for at least 300 μs.
Continuous activation of TX is possible, in which case the input data is transmitted
continuously.
In the case of inactivation, transmission of the current telegram is completed. TX
does not affect the receiving characteristics.
• The receiver never receives garbled telegrams
• Point-by-point data transmission is possible (transmission of a single telegram)
This output signals the presence of valid data at the receiver. In the event of a
faulty transmission or if the light beam has been interrupted, the output remains in-
active ("O").
In the no-signal status, the outputs are set at "O", active signals are indicated by "l".
