NEU: iRidium mobile – Controlling system with all Global Caché drivers


Controlling systems with Global Caché

The communication protocol is open, so you can use the device with all IP-enabled control systems.

Example Stardraw Control

gc Stardraw

Example AMX *

gc AMX

For some brands on the market (* AMX, Crestron *) there are complete application drivers available to download. In Stardraw Control the driver is already integrated.

Why Global Caché?

gc 100 all
  1. Simple cabling over Ethernet:
    Every IP-Network can be used, no separate bus cable necessary
  2. Price
    A bi-directional RS-232 interface costs about 30 - 40 Euro (list price)
  3. Control interfaces:
    RS-232 uni-/bi-directional, IR, Relays, contact closures
  4. Easy programming:
    Pre-programmed drivers for AMX*, CRESTRON* and Stardraw Control
  5. All-purpose:
    Compatible to all control systems that can output control commands over a network interface
  6. Flexible application:
    Products can be used as a remote bus device or as a 19“ control port extension in the rack

iTach Flex

  • iTach Flex
    iTach Flex, an industry first, is a smart end-point that Wi-Fi or network enables electrical devices instantly. The Flex adds intelligence to the enabled device, allowing events and tasks to be triggered with simple macro commands. In addition, the Flex supports HTML for web browser control from anywhere in the world and includes a real-time clock to support timed events for true automation

IR Accessories

  • GC-IRL
    IR-Code Learner. Integrated in a 9pol Sub D connector for the operation at a RS-232 interface, either at a PC or at a GC-100 IP-Bus Device.
    Frequency spectrum: 20 KHz – 500 KHz
  • GC-IRE
    IR – RS-232 Extender, used to digitize IR signals to serial information. Integrated in a 9pol Sub D connector, the GC-IRE processes IR signals between 20 KHz and 500 KHz. By using the IR receiver GC-RG1 the GC-IRE provides the receiver with the required supply voltage.
  • GC-RG1
    The IR Receiver GC-RG1 can be installed inconspicuously with its 2m of cable set and its extremely small box (25x5x10mm WxHxD) and allows using any hand-held transmitter (30-72 KHz Carrier) in combination with control systems.


The Global Caché cable sensors are connected to an IR port of the GC-100 IP Bus Devices. When the sensors in operation indicate a change in state, they release an event over the network which can be evaluated by the control system connected to it.

The following sensor products are available:

  • Video Sensor GC-SV1
    The GC-SV1 has a highly resistive sensor input for video signals. The cable with 2m length has a cinch connector with loop through possibility which can be directly connected to a FBAS output. The sensor receives the required supply voltage of 5V from the IR-port of the GC-100.
Video Sensor GC-SV1
  • Voltage Sensor GC-SP1
    The sensor detects voltages on 0 or 1. AC/DC voltages from <±2V will be valued as 0, higher ones as 1. Max. input voltage is ± 24V. The output voltage (TTL) is separated galvanically from the sensor voltage (optical coupler).
Voltage Sensor GC-SP1
  • Contact Closure Sensor GC-SC1
    The sensor detects the state of the connected potential-free switches / push buttons. The integrated electronic provides, because of its hysteresis, a debouncing of the controlled contacts.
