GIMSON ROBOTICS GR-TX-868A2 Hand Held Remote Control Transmitter
Remote Transmitter Instructions
The GR-TX-868A2 is a stylish 3-button remote control that is compatible with the GR-RX-868A (and GR-RX-868A2) receiver module and also some 868MHz receiver products by RF Solutions Ltd. The three rubberized buttons and The slim rounded body offer an ergonomic means of controlling various devices, typically those involving bidirectional output such as electrically controlled windows or blinds. Meanwhile, the included magnetic wall holder provides a convenient way of mounting the controller on a surface, for quick and easy access (mounting via two 3mm screw holes in the rear of the casing). The controller has been designed, assembled, and tested in the UK. It is designed for indoor use only and is not waterproof. Pressing any button will send a single RF ‘packet’ of information, and the Blue LED on the remote (towards the top of the body) will illuminate briefly. Releasing a button will similarly generate a packet (since these responses are based on the change in button state), which any in-range compatible receiver may respond to.
Operating Range
This transmitter has been tested, in tandem with the GR-RX-868A receiver module, for an operating range of at least 80m in open field line-of-sight conditions. The effective operating range can be affected significantly by obstacles, surfaces, atmospheric conditions, and nearby sources of electromagnetic interference. Large metal objects and surfaces can especially affect the operation range, and so are best avoided. Be aware that operation is possible out of the line of sight, see warnings below.
Safety
The RF module upon which this device is based (ZPT-8TS) is designed and tested
by the manufacturer
RF Solutions Ltd to meet Radio Equipment Regulations 2017 (2014/53/EU)
standards. It is important to carefully consider any potential risks from the
use of radio-controlled systems in the end application.

- It is critical that all regulations and warnings on this document are adhered to, Gimson Robotics Ltd declines liability for damages caused by not following these instructions.
- Before using this device, it is compulsory to read and understand these instructions and those of any associated hardware (RF receiver, and connected hardware). If any information in relation to the remote is unclear, please contact us via the details below.
- The GR-TX-868A is a general-purpose remote control, without a defined end application. It is important to carefully consider any potential risks from the use of radio-controlled inputs in the end application. Bear in mind that out-of-sight operation is possible. Any system should include appropriate failsafe and user warnings based upon the possibility of an unexpected operation via the RF interface.
- The remote and the wall holder each enclose N35 Neodymium magnets, keeping these away from sensitive electronic devices. Do not attempt to open the casing beyond the battery hatch.
- This equipment is not intended for use by children, and should be mounted or stored safely away from their access.
Remote Batteries
The remote takes two AM batteries, which are not included. You should use quality batteries from reputable brands only. Either rechargeable 1.2V NiMH or non-rechargeable 1.5V Alkaline batteries are compatible (both batteries in a pair should be matched). The battery compartment is accessed via a hatch on the lower rear of the remote, which slides away from the body. The hatch is intended to be child-proof, and so needs to be pressed firmly down to release the clip at its top, to slide it away. It can be easier to apply this pressure with a tool, such as a large screwdriver applied across sideways, or a rolling pin, pushing above the arrow-marking on the rear until it unclips. Ensure that batteries are inserted the correct way around by following the markings in the battery compartment. If the effective operating range drops noticeably, or the LED fails to illuminate when buttons are pressed, the batteries may need replacing. The A2 version of the remote includes an improved battery management design, with extremely low idle battery draw.
