 +
 +===== Datacast operation =====
 +<WRAP indent>
 +
 +TECH units support Datacast TCP/IP over OTA broadcast. Datacasting often provides news, weather, traffic, stock market, and other information which may or may not relate to the program[s] it is carried with. An electronic program guide is usually included. Datacast TCP-IP packets are reassembled and then routed to the LAN port.
 +
 +Example:
 +
 +Discover the device:
 +
 +<WRAP indent>
 +<code>
 +hdhomerun_config discover
 +</code>
 +</WRAP>
 +
 +Set the physical channel:
 +
 +<WRAP indent>
 +<code>
 +hdhomerun_config FFFFFFFF set /tuner0/channel auto:651000000
 +</code>
 +</WRAP>
 +
 +Set the datacast PID:
 +
 +<WRAP indent>
 +<code>
 +hdhomerun_config FFFFFFFF set /tuner0/filter 0x0A00
 +</code>
 +</WRAP>
 +
 +Set the target:
 +
 +<WRAP indent>
 +<code>
 +hdhomerun_config FFFFFFFF set /tuner0/target datacast
 +</code>
 +</WRAP>
 +
 +</WRAP>
 +
 +===== Boot scripts =====
 +<WRAP indent>
 +
 +The /sys/boot variable allows the TECH unit to automatically set variables at startup, allowing you to preserve settings across power outages or simply set the power on defaults.
 +
 +The syntax for the /sys/boot consists of multiple lines of text; a variable name followed by a single space and then the value: (there should not be any space before the variable name)
 +
 +<WRAP indent>
 +<code>
 +<variable1> <value of variable1>
 +<variable2> <value of variable2>
 +...
 +<variableN> <value of variableN>
 +</code>
 +</WRAP>
 +
 +Example (save as boot.txt):
 +
 +<WRAP indent>
 +<code>
 +/tuner0/channelmap us-cable
 +/tuner0/channel 103
 +/tuner0/program 4
 +</code>
 +</WRAP>
 +
 +To place a wait period between commands you can use the "sleep" command followed by the number of seconds:
 +
 +<WRAP indent>
 +<code>
 +<first command>
 +
 +sleep 60
 +
 +<next command>
 +</code>
 +</WRAP>
 +
 +
 +To store the configuration to the device:
 +
 +<WRAP indent>
 +<code>
 +Format: hdhomerun_config <id> set /sys/boot - < filename
 +Example: hdhomerun_config FFFFFFFF set /sys/boot - < boot.txt
 +</code>
 +</WRAP>
 +
 +Changes will be applied the next boot; to execute the new /sys/boot immediately:
 +
 +<WRAP indent>
 +<code>
 +Format: hdhomerun_config <id> execute
 +Example: hdhomerun_config FFFFFFFF execute
 +</code>
 +</WRAP>
 +
 +</WRAP>
 +===== Static IP assignment =====
 +<WRAP indent>
 +
 +A static IP address can be configured using the following command (the quotes are required as shown):
 +
 +<WRAP indent>
 +<code>
 +Format: hdhomerun_config <old ip> set /sys/ipaddr "<new ip> <subnet> <gateway>"
 +Example: hdhomerun_config 169.254.34.98 set /sys/ipaddr "10.10.20.43 255.255.255.0 10.10.20.1"
 +</code>
 +</WRAP>
 +
 +Note: The TECH requires a gateway when used to stream multicast, even if on the same subnet.
 +
 +==== Reverting to DHCP ====
 +<WRAP indent>
 +
 +The TECH can be configured for DHCP operation (default) using the following command:
 +
 +<WRAP indent>
 +<code>
 +Format: hdhomerun_config <old ip> set /sys/ipaddr dhcp
 +Example: hdhomerun_config 169.254.34.98 set /sys/ipaddr dhcp
 +</code>
 +</WRAP>
 +
 +<WRAP info>
 +If you cannot access the TECH due to the IP address change, do the following to reset:
 +
 +Set a static IP on the computer in the 169.254.x.y range (e.g. 169.254.1.9) with a 255.255.0.0 subnet mask. The auto IP address for the TECH device will be randomly chosen within the 169.254.x.y range. Use the [[https://download.silicondust.com/hdhomerun/hdhomerun_tech_windows.exe|TECH Config GUI]] to locate it and reset the IP.

 +
 +===== Setting the channel map =====
 +<WRAP indent>
 +
 +The channel map is a non-volatile configuration option that is used to set the channel to frequency table, to configure the channel scan table, and to optimize the auto-modulation detection.
 +
 +GUI: The channel map can be set for each tuner by running HDHomeRun Config (GUI).
 +
 +Command line: The channel map can be set for each tuner using the following command:
 +
 +<WRAP indent>
 +<code>
 +Format: hdhomerun_config <ip|id> set /tuner<n>/channelmap <channelmap>
 +Example: hdhomerun_config 10001000 set /tuner0/channelmap us-cable
 +Example: hdhomerun_config 10001000 set /tuner1/channelmap us-cable

 +===== Multicast =====
 +<WRAP indent>
 +
 +TECH supports multicast streaming within a network.
 +
 +  - Using HDHomeRun Config GUI or hdhomerun_config choose a desired channel and program number for each tuner. In this example we will use channel 19 program 3 on tuner 0 and channel 30 program 1 on tuner 1.
 +  - Choose a multicast IP address for each stream. As a general rule the multicast address should be in the range of 239.255.0.0 to 239.255.255.255. In this example we will use 239.255.1.1 and 239.255.1.2
 +  - Choose a destination (client) port number. The port should be outside the the well-known ports range (we recommend 50000+) and should be unique for each stream. In this example we will use 59001 and 59002.
 +  - Write the boot script (text file):<WRAP><code>
 +/tuner0/channelmap us-bcast
 +/tuner0/channel 19
 +/tuner0/program 3
 +/tuner0/target rtp://239.255.1.1:59001 ttl=64
 +
 +/tuner1/channelmap us-bcast
 +/tuner1/channel 30
 +/tuner1/program 1
 +/tuner1/target rtp://239.255.1.2:59002 ttl=64</code></WRAP>
 +  - Write the boot script to the device: <WRAP><code>hdhomerun_config 10010003 set /sys/boot - < boot.txt</code></WRAP>
 +  - Execute the boot script: <WRAP><code>hdhomerun_config 10010003 execute</code></WRAP>
 +  - Check the tuner status and target for each tuner. The packets-per-second “pps” number should be non-zero indicating that the device is sending the stream. <WRAP><code>hdhomerun_config 10010003 get /tuner0/debug
 +hdhomerun_config 10010003 get /tuner0/target
 +hdhomerun_config 10010003 get /tuner1/debug

 +When using the TECH3-CC or TECH4 and later, the consumer [[:app|HDHomeRun app]] can be used, allowing the TECH to behave as a consumer HDHomeRun unit. To enable this the TECH will need to sync with the HDHomeRun guide server on the internet:
 +
 +  - Access the web interface of the TECH unit //(for example, <nowiki>http://192.168.0.49</nowiki> )//
 +  - Check the option **"Sync with guide server"**
 +  - All other features of the TECH can still be used in this mode.
