Function
The DAD 15-8P can be used to transfer data words eight bits wide bidirectionally.
A device pair is required to set up a transmission route. One device is operated as the MASTER (high level on the Master/Slave
input) and the second one as the SLAVE (low level on the Master/Slave input).
All binary control signals present in parallel on inputs D1 - D8 are converted serially into an 8-bit sequence in the device, are
transferred over the light route and are again applied in parallel in the receiver to outputs D1 - D8. Interference-resistant PPM
modulation is used to transfer binary signals. The entire cycle during which the two current 8-bit words are transferred one after
the other in both directions, in the time multiplex procedure, lasts 35 ms. This corresponds to a data rate of 350 Baud. This time
multiplex procedure is of no significance to the user, since the last data to be received is stored and is available on the outputs
until the next change is made.
Output behaviour when the beam of light is interrupted
The behaviour of the data outputs when the light beam is broken can be adjusted with the aid of the 4 switch (data latch):
OFF: Data outputs are turned off when the light beam is broken.
ON: The last data to be received remains intact on the outputs when the light beam is broken.
Input/output / emitter deactivation
A high level on the ENABLE input is required to operate the DAD15-8P. If there is a low level on the ENABLE input, the emitter
will be turned off.
The ENABLE input has no function in SLAVE mode.
Inputs and outputs, reception indicator:
Receiver
Emitter
The states of data inputs and outputs are displayed individually via LEDs. A high level on the input is indicated by a green
LED. A red LED indicates an active output.
Correct reception is indicated with the output and the RE-
RxD
CEPTION INDICATOR LED.
The SYNC output indicates the end of a transmit or receive
cycle. Output data are valid with a falling edge and new input
data can be read.

Chaining
The SYNC output can also be used to start an additional ENABLE input. Up to four MASTERS can be chained together
in this manner. The devices must then be addressed by
means of the A1 and A2 address switches. The SLAVE belonging to the MASTER in question requires the same
address switch setting.
Arrangement and mounting
The DAD15 data light barrier consists of an electronics unit
with spring-loaded terminals and 2 M16 cable glands.
The electronics unit is connected with an internal connector.
It is also fastened to it with 4 screws.
