ONEFORALL Universalfernbedienung URC 3741 Protecto für Video-Disk-Recorder (ya)VDR
Zur Bedienung meines VDR benutze ich bis jetzt die Fernbedienung ORC 7562 von ONE FOR ALL. In einem Haushalt mit insgemsammt 12 Beinen passsierte es leider zu oft, dass die Fernbedienung zu Boden fiel und letztendlich in die ewigen Jagdgründe des Elektroschrotts sich wiederfand.
Da ich mit den Geräten von ONE FOR ALL eigentlich gut gefahren bin, habe ich mal umgesehen, ob es da nicht eine Fernbedienung gibt, die ein wenig robuster und somit geschützer für den Hardcore-Familieneinsatz ist. Die Wahl fiel dabei auf die URC 3741 Protecto. Wie auch schon bei der URC 7562 galt es bei der URC 3741 Protecto einen Code zu finden, der die anderen HiFi-Komponenten nicht stört. Der Code 200 hat sich als der bestunterstützte bei den verschiedenen Test herauskristallisiert.
(HD-)VDR auf Basis yaVDR
Bedingt durch meine diversen Projekte, dem Dokuwiki, meiner Wetterstation und der Betrieb meiner Postfix-Installationen hier, habe ich bei meiner dritten VDR-Installation entschieden, auf eine fertige VDR-Distribution zurückzugreifen. Zumal hat sich in den 10 Jahren VDR, doch auch einiges getan in Sachen Anzeige, Bedienung und Co. Nach meiner Um- und Anfrage im VDR-Portal habe ich mir die gängigsten und aktuellst gepflegtesten VDR-Projekte mal genauer angekuckt. Meine Wahl fiel dabei auf das Projekt yaVDR und das owohl ich persöhnliche eine bekannte Aversion gegen Ubuntu habe. Aber ab und an muss man dann doch über seinen Schatten springen und somit wurde der VDR mit yaVDR gebaut.
Als erstes das ISO-Image yavdr64 0.5.0a von der Installationsquelle herunterladen und eine Instalations-CD brennen.
Nach der Installation aktivieren wir als erstes unseren root-Account.
$ sudo passwd root
Als nächstes werden wir root.
$ su -
Anschließend führen wir einen Systemupdate durch.
# apt-get update && apt-get dist-upgrade
Die fehlenden Kernelmodule für die DVB-Karten DD Cine S2 V6 - Twin Tuner Karte DVB-S/S2 müssen nun noch installiert werden.
# apt-get install media-build-experimental-dkms
Nach einem Reboot des Systems, stehen dann die Karten zur Verfügung.
# reboot
# ll /dev/dvb/

Programmierung und Einstellung
Da ich für den Betrieb meiner Fernbedienung einen selbstgebauten LIRC-Empfänger verwende, ist bei der Integration in yaVDR ein wenig mehr Aufwand von Nöten, als bei der Verwendung eine 0815-USB-IR-Fernbedienung.
Damit die URC 3741 Protecto optimal in den yaVDR sind nun ein paar Schritte notwendig.
- Schnittstellendefinition: Zu aller erst definieren wir im yaVDR Web Configuration Frontend bei der einstellung der Fernbedienung den COM-Port an dem der LIRC-Empfänger angeschlossen ist und um welchen Empfängertyp es sich dabei handelt. In unserem Fall ist die Schnittstelle /ev/ttyS0 (COM1) und als Empfänger Home-brew (16×50 UART compatible serial port).
- yaVDR stoppen: Nachdem wir uns mit der Konsole des yaVDR als User Root verwunden haben, stoppen wir den laufenden VDR-Daemon.
# stop vdr
vdr stop/waiting
- eventlircd stoppen: Als nächstes stoppen wir den eventlirc-Daemon, einem Filter, der die Eingaben der Fernbedienungen auswertet und an den VDR-Daemon weiter. Den Daemon stoppen wir nun auch mit:
stop eventlircd
eventlircd stop/waiting
- lirc und Fernbedienung testen: Bevor wir nun die Fernbedinung anlernen, überprüfen wir ob der Empfänger überhaupt funktioniert und die Tastendrücke der Fernbedienung erkennt. Da der verwendete LIRC-Empfänger am COM1-Port angeschlossen ist, verwenden wir die zugehörige Treiberdatei /dev/lirc0.
# mode2 -d /dev/lirc0
space 16777215 pulse 1825 space 1713 pulse 1797 space 1715 pulse 1797 space 856 pulse 915 space 839 pulse 894 space 863 pulse 901 space 1718 pulse 1771 space 1742 pulse 890
Da beim Drücken verschiedener Tasten auf der Fernbedienung entsprechende Rückmeldung auf der Konsole angezeigt werden, können wir den Test schon mal positiv beenden.
- LIRC-Namespace: Da wir beim Anlernen der einzelnen Tasten im nächsten Schritt, die standardisierten Namen der Tasten des lircd-Projektes benötigen, lassen wir uns erst mal anzeigen, welche Tatsennamen dies sind.
# irrecord --list-namespace > /root/lirc.namespace
Diese Datei lassen wir und dann am besten in einer separaten Konsole anzeigen, damit wir später nach den benötigten Key-Names greppen können.

# irrecord -d /dev/lirc0 /etc/lirc/lircd.conf
irrecord - application for recording IR-codes for usage with lirc Copyright (C) 1998,1999 Christoph Bartelmus(lirc@bartelmus.de) This program will record the signals from your remote control and create a config file for lircd. A proper config file for lircd is maybe the most vital part of this package, so you should invest some time to create a working config file. Although I put a good deal of effort in this program it is often not possible to automatically recognize all features of a remote control. Often short-comings of the receiver hardware make it nearly impossible. If you have problems to create a config file READ THE DOCUMENTATION of this package, especially section "Adding new remote controls" for how to get help. If there already is a remote control of the same brand available at https://www.lirc.org/remotes/ you might also want to try using such a remote as a template. The config files already contain all parameters of the protocol used by remotes of a certain brand and knowing these parameters makes the job of this program much easier. There are also template files for the most common protocols available in the remotes/generic/ directory of the source distribution of this package. You can use a template files by providing the path of the file as command line parameter. Please send the finished config files to <lirc@bartelmus.de> so that I can make them available to others. Don't forget to put all information that you can get about the remote control in the header of the file. Press RETURN to continue. Now start pressing buttons on your remote control. It is very important that you press many different buttons and hold them down for approximately one second. Each button should generate at least one dot but in no case more than ten dots of output. Don't stop pressing buttons until two lines of dots (2x80) have been generated. Press RETURN now to start recording. ................................................................................
