8.1.4.2 Preferences −> Auxiliary data −> GPIO
SERV/LINK offers the possibility to use physical GPIOs, or virtual GPIOs through UDP ports. The status of the
physical or virtual GPI’s is tunneled in-band so that the decoder can output the status information on physical or
virtual GPO’s. Note that physical GPIOs is an hardware option of IQOYA SERV/LINK.
Virtual GPIO’s allow third party applications to send/receive status information via IP to/from IQOYA.32 virtual
GPI status can be tunneled.
Structure of a virtual status information frame over UDP
The validation mask validates the GPI statuses to be taken into account.
The page
Preferences −> Auxiliary data −>GPIO allows enabling/disabling the in-band tunneling of GPI status
information to GPO.
Generic: serial data are inserted as they arrive.
UECP: serial data are inserted each time a complete RDS UECP
frame is fully received from the RS232 port.
Baud rate Read/Write Serial port baud rate in bits/s, from 1200 bps to 40 Kbits/s
Data bits Read/Write Select the number of bits for each character (6, 7 or 7)
Stop bits Read/Write Enter the number of bits used to signal the end of a character: 1 or 2.
Parity Read/Write Select the method used for detecting errors on the RS232 port
transmission:
● None: No
● Odd: number of bits of each character (including the parity bit) is
always odd.
● Even: number of bits of each character (including the parity bit) is
always even.
Status Read/Write Enable: the COM port is enabled.
Disable: the COM port is disabled.
