Common Design


Qameleon products are designed for remote operation, whether it is 1 foot away or on the other side of the world.They support multiple user interface devices (PCs, tablets, phones) using common communication mechanisms. Qameleon hardware devices are often interfaced to other instruments and systems, such as variable frequency drives (VFD), power quality monitors, liquid level sensors and machine controllers.

All Qameleon hardware units include the same external interfaces for communication with other devices and systems.

Two RS232 serial ports for connecting to external devices. An optional RS485 is available.
Digital Inputs
Eight  optically-isolated digital inputs can be used to receive signals from controllers and other instruments.
Digital Outputs
Eight solid-state relays can be used to send signals to contollers and other instruments.
One Ethernet port is used to communicate with remote user-interface devices. An external connector is optional. The Ethernet can be connected directly to a single PC, or it can be part of a network. Each Qameleon hardware unit has its own user-configurable IP address.
WiFi is the primary communication mechanism for Qameleon hardware units. It can be used to connect directly with user-interface devices or can be part of a network. The WiFi adapter can be configured to connect to an access point (infrastructure mode) or it can be configured to be a “Soft Access point”. An external antenna is provided. A remote antenna can be used for units in an inaccessible location.
Cellular (optional)
 All Qameleon hardware units can be provided with a 4G LTE modem for remote operation anywhere in the world. A commercial off-the-shelf modem is connected to the internal Ethernet port. The owner can specify their cellular carrier or we will arrange for the cell connectivity with an MVNO. The cellular modem is enclosed in a slightly larger environmentally sealed box. Two external antennas are used.
