General Purpose Input Output (GP Option)
The Streamer and InStreamer equipment allows 2 General Purpose (GP) Input and Output. The
GP name are GPI6 and GPI7 for the inputs and GPO6 and GPO7 for the output
GPInput
In order to activate GP6 and GP7 inside Streamer, place directly on ground the “In” signal ( IN to
GND) as shown in picture.
It is already possible employs both connectrs GND. Please remember that IN and GND are directly
connected to µProcessor (µP) equipment.
Pay attention to don’t connect external voltage to this connectors.
These connectors can be directly applied to Axel Technology equipments as BOBCAT and
BoxRelè, already made in order to manage all kind of signals coming from CD player, MD Player,
tape recorder, ISDN tunneling or Automation System.
GPOut
Inside InStreamer are presents two BiStable Relay, iIn order to employ the GPOut.
These Relays allows TWO condition: NC and NO.
NC = Normally Close
NO = Normally Open
C = Common Contact
Details:
When there are no activation in GPI the Relay contact stay on NC. When GPI become activated,
the output relay change the contact closure versus NO, as showed in picture.
In the example figure, a cc generator is connected in the common contact and the same point
directly to LAMP1 and LAMP2.
In GPI non-activation position, LAMP1 is ON, and LAMP2 is OFF
In GPI Activation position, LAMP1 is OFF, and LAMP2 is ON
Working votage = 5 Vcc
Maximum Voltage (breakdown) = 100 Vcc
