Kristian Larsson edited this page Dec 29, 2015 · 5 revisions

This binding is designed to interface with BenQ projectors that have an RS232 interface on them that accepts the commands documented by BenQ in [1].

Status

This binding is current in Beta state with the following commands implemented:

Command Query Set Comments
Power Y Y
Mute Y Y
Volume Y Y
Source Y Y Can be returned as either a string or number
Lamp Time Y N

Tested Devices:

  • BenQ W1070
  • BenQ W1080

Transports

The binding support transport using a TCP/IP to RS232 converter or via a direct RS232 interface.

USR-TCP232-2 is a known working TCP/IP to RS232 converter.

Binding Configuration

############################# BenqProjector Binding  ########################################

# mode controls how the projector can be reached. 'serial' is for a directly
# connected RS232 serial interface while 'network' is for using a TCP/IP to
# serial converter
#benqprojector:mode=network

# For mode=network, define the Serial to Ethernet device location
#benqprojector:deviceId=<hostname>:<port>

# For mode=serial, define the serial device (e.g. /dev/ttyUSB0) and speed
# (defaults to 57600 bps)
#benqprojector:deviceId=<device>:<speed>

# Define polling interval in milliseconds
#benqprojector:refresh=15000

Item Configuration

Example of Item bindings:

Switch gf_lounge_multimedia_projectorPower "Projector Power" (gf_lounge, gf_multimedia) {benqprojector="power"}
Switch gf_lounge_multimedia_projectorMute "Projector Mute" (gf_lounge, gf_multimedia) {benqprojector="mute"}
Number gf_lounge_multimedia_projectorVol "Projector Volume [%d]" (gf_lounge, gf_multimedia) {benqprojector="volume", autoupdate="false"}
Number gf_lounge_multimedia_projectorSourceNum "Projector Source [MAP(ProjSourceNum.map):%s]" (gf_lounge, gf_multimedia) {benqprojector="source_number"}
String gf_lounge_multimedia_projectorSourceString "Projector Source [%s]" (gf_lounge, gf_multimedia) {benqprojector="source_string"}
Number gf_lounge_multimedia_projectorLamp "Projector Lamp [%d hours]" (gf_lounge, gf_multimedia) {benqprojector="lamp_hours"}

Example source mapping:

0=Computer
1=Computer 2
2=Component
3=DVI-A
4=DVI-D
5=Sky TV (HDMI)
6=Chromecast (HDMI2)
7=Composite
8=S-Video
9=Network
10=USB Display
