2. PARALLEL IN-OUT Connection
The signal inputs entering the parallel inputs 1-8 on the control site are output to the parallel outputs 1-8 on the remote site.
(Similarly, the signals entering the remote site are output to the control site.) If any one of the parallel inputs is closed, then
the corresponding parallel output is generated.
The switches connected to the control site can be used for the shut/release of the electronic lock connected to the parallel
port of the remote site via relays, etc., or for ON/OFF switching of lighting.

● Forced disconnection input terminal
Communication is forcibly finished if the making condi-
tion continues for more than 100 ms between the forced
disconnection input terminal and the nearest GND ter-
minal.
● Mid-communication output terminal
When the line is connected and communication is start-
ed with the destination, this connector is closed.
There is no perfect coincidence between video or audio
and output timing. This is an open-collector output.
● Strobe output terminal
When data at the parallel output connector is updated,
the strobe pulse output is generated from this connec-
tor.
● Clock adjust input terminal
When this input terminal is closed, the clock incorporat-
ed in the WJ-NT204 can be corrected. The electrical
conditions are the same as those for parallel input.
Closure should be maintained for more than 100 ms.
