Menu: Encoder / GPIO
The General Purpose Input/ Output (GPIO) supports a GPI function for the pass-through mode to control
devices which are connected with another ENC-300
™ or DEC-200™. Furthermore it supports a GPO
function for manual mode to send a signal to a device which is directly connected to the encoder via the
GPIO D-
Sub connector of the breakout cable ‘P’. This allows users to connect a special device, e.g.
from the encoder a sensor sends a signal to control the special device.
.!.
At the ENC-300-HDSDI, the Sub-D 26-pin connector for the breakout cable has the input
and output for GPIO. At the ENC-300-DVI, GPIO is only usable, when you use the FR-
610 chassis. The FR-610 chassis has the input and output of GPIO at the rear side.

Settings:
Description:
Mode:
Specifies the GPIO mode.
‘Manual’
switches the local GPO value to the level high (=1) / low
(=0). The high/low level must be entered in the ‘GPO-Value’ field.
‘Passthrough/A’
and
‘Passthrough/B’
forward the high (=1) or
low (=0) level via UDP to another encoder or decoder at which a
device is connected. Therefor the IP-address of the destination
encoder/decoder must be entered in the ‘Destination’ field. The
difference between ‘Passthrough/A’ and ‘Passthrough/B’ is that the
GPO value of ‘Passthrough/B’ is inverted. ‘Passthrough/A’ and
‘Passthrough/B’ has the following states:

GPO-Value:
Specifies the GPO high / low level. Low level = ‘0’ and high level
‘1’. This field is only in use, when the ‘Manual’ mode is set.
Destination:
Specifies the IP-address of the destination encoder/decoder to
which the connection shall be created. This field is only in use,
when the mode is set to ‘Passthrough/A’ or ‘Passthrough/B’.
GPI-Value:
Shows the high/low level which the encoder gets. Read only field.
