How to Configure Global Cache
iTach Flex with HC2
Step-by-step guide
Global Cache iTach Flex it’s a device you can use to integrate
any IR controlled device using Virtual Device in Home Center 2.
iTach Flex allows you to control AV equipment ( TV, AV receiver,
cable/satellite box, DVD player ) and any other automation
device controlled with IR ( infra-red commands ) or RS-232

iTach Flex Quick Start
Initially, or when default- ed, iTach Flex WiFi units are an unsecured “adhoc” device discoverable with any
WiFi network-enabled device. After applying power using the power supply or USB to power, view
available wireless networks and connect to the Flex in the Networks list. The Flex is named with its
unique MAC ID, which is printed on the bottom label.
For example, if the MAC ID is 000C1E- 01B45C, the wireless network name will be
ITACHFLEX000C1E01B45C. WPS is supported and can be initiated by holding down the side button on
the Flex for 4 seconds and then releasing. The LED will flash quickly to confirm WPS mode.
Using iTach with Ethernet port you have to connect it directly to your computer and change network
adapter settings to match IP range of default iTach Flex settings.
For example : 192.168.1.x
X – represents any available
value different than 70.
WiFi Setup
Select iTach WiFi ( adhoc ) from the wireless network list
on your computer..
iTach FLEX WiFi will check for available wireless networks. Select your wireless network and put
password associated with your network.
Once the connection is established, open a
browser and view iTach’s configuration
page. If you’re not directed to the default IP
address for the Flex, http://192.168.1.70,
then enter it in the address bar.
Select the SSID and enter the Passphrase of your network into the fields on this page. In order for the
Flex unit to connect properly, the network credentials must match the router settings. At this point, the unit
will connect to the chosen network using DHCP. Flex units require up to 30 seconds to connect
to a network once settings are changed. The power LED will blink one time per second once connected.
Flex units will not connect to a network with 802.11g disabled.
When testing IR functionality, verify the Flex Link Port is configured as “Single IR Emitter” and connect the
supplied IR emitter to the unit. In the “Single IR Emitter” mode, the iTach Flex will respond to and execute
commands related to IR functionality, i.e. “sendir.”
When testing serial/RS232 functionality, verify the Flex’s Flex Link Port is configured as “Serial” with the
correct baud rate and serial settings necessary for your application. Then, connect the supplied Serial
Flex Link cable to the Flex. Use the correct RS232 cable to connect to the device. The serial Flex Link
cable provides a standard male DB9 connection with Tx and Rx on pins 2 and 3, Gnd on pin 5, and RTS
and CTS on pins 7 and 8. The wiring of the cable between the RS232 Flex Link cable and the controlled
hardware is determined by the settings of the device you are attempting to control.
Flex units ship with a metal cradle which can be secured to any surface for easy mounting and placement.
Push the flange gently and pull the Flex carefully to remove from cradle.
IR Learning. Each Flex has an internal IR learner. To use it, download the iLearn application from
downloads page and follow the tutorial located at www.globalcache.com/support. Once connected to
the learner, simply point the remote at the small hole located at the top center of the Flex and input any
button you want captured by iLearn.
Troubleshooting. Flex configuration can be reset to factory defaults by pressing and holding the reset
button (located around the side to the right of the Flex Link Port) for 8 seconds and releasing. The LED
will blink quickly at 4 seconds to confirm WPS, and blink faster at 8 seconds to confirm default.
Use following link to download GlobalCache tools to configuration software:

iHelp - The iHelp utility is used to locate and
configure iTach Flex, iTach devices, and GC-100s
installed on the network, and also facilitates the
upgrade functionality for the iTach Flex and iTach
family of products. Run iHelp.exe on a Windows PC
connected to the same network as your GC devices.
iHelp listens for iTach Flex, iTach, and GC-100
multicast beacons and displays every MAC ID and IP
address within one minute. Configure your GC
product by selecting it from the list, right-clicking on
the unit, and selecting “Configure” to display the
setup pages on your default browser. iHelp will
automatically notify you if your unit is out of date to
begin a firmware upgrade.
Network Settings
When you type in your browser IP address of your
device you will access configuration page.
iLearn – This executable is the
companion application for our IR
products, including all iTach models,
the GC-IRL, and the GC-IRE (with
attached GC-RG1). This utility
allows for the capture of IR
commands, conversion between
Global Caché and Hex (CCF)
formats.
Select Connection IR Learner , type
an IP address and click “Connect”
button.
Connected device will be displayed
and ready to learn IR commands.
1. Point your remote to IR learner hole and press the button you want to learn.
Lines with IR code will show up ( highlighted in dark blue ).
2. Press “Edit” button to trim the string and type Button Name.
3. Press “Save”.
In the Edit View window our IR code will show up..
4. Copy trimmed code.
Our copied IR code line will looks like this:
sendir,1:1,1,37825,1,1,171,171,21,64,21,64,21,64,21,22,21,22,21,22,21,22,21,22,21,64,21,64,21,64
,21,22,21,22,21,22,21,22,21,22,21,22,21,64,21,22,21,22,21,22,21,22,21,22,21,22,21,64,21,22,21,64
,21,64,21,64,21,64,21,64,21,64,21,1778
In order to make this IR code works with our Virtual Device and be understandable for GlobalCache,
add to the end of the code 0x0D0x0A.
You can use Notepad to edit final code. Make sure there’re no spaces inside the code and everything is
trimmed as a single line.
Our final code will look like this and be ready to copy and paste inside our Virtual Device button
sendir,1:1,1,37825,1,1,171,171,21,64,21,64,21,64,21,22,21,22,21,22,21,22,21,22,21,64,21,64,21,64
