AC Adapter
Appearance
Description
This is an AC adapter used when operating this unit at AC100V~240V/2A, and supplies DC24Vto this unit. With this AC adapter.
Preparation
Connect the M12 connector (Power) to the left-hand side of the connector shown below. One adaptor supplies the power to the one transmitter.
The right-hand side of the connector is not in use.
Connect the AC adaptor to the AC100V power outlet.
Operation (Indoor Use Only)
Once the AC adapter is connected to the M12 connector, PTXMP starts running,
and the Tx power is on. To turn it off, disconnect the AC adapter.
Note : The PTXMP transmitter shall be installed by professionals on an
indoor structure that is not accessible to outsiders. PTXMP device needs to be
installed in a fully enclosed, waterproof room in an indoor structure and
cannot be accessed by non-professionals.
TURNING ON
TURNING Off
- Disconnect the AC adaptor from a power outlet
- Disconnect the M12 connector cable from the Transmitter
Precautions and considerations
This device will be a PoC/evaluation device which can be available upon PoC/Evaluation request and agreement with Aeterlink Corp. directly and requires indoor operation only such as office environment. It does not have such functions as water and dust resistance. Aeterlink provides the users/customers who will be involved in the PoC/evaluation with further precautions and warnings in terms of the possible radio exposure in person when delivery of DUTs. A sticker saying “Always keep distance from DUT by >2 inches (~50mm)” will be placed on the surface of the DUTs. Since it is a device that emits radio waves, please use it within the scope of the Radio Law as well. The transmitter can be installed on either wall or pillar with four bolts with washers by professionals. There are four bolt holes at each corner. See photos below. Recommended bolt: M4 with flat washer Recommended tightening torque: 1.3±0.2N·m
The actual use distance: 50mm ~ 6,000mm (effective range). The maximum number
of devices that can be charged simultaneously: 300 devices sitting within the
effective range mentioned above.
Note : The distance is subject to vary due to the environment and usage
conditions but for the typical use case. Refer to Supplemental Information at
the end of this document.The minimum distance from PTXMP to avoid RF exposure
for safety: 50mm. During operation, the temperature of the backside metal part
increases. Short-term skin contact will not cause immediate burns, but please
be careful when handling during operation or immediately after stopping.
FCC
CAUTION
Note : This equipment has been tested and found to comply with the limits
for a Class A digital device, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense. This
equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment and meets the FCC radio frequency (RF) Exposure
Guidelines. This equipment has very low levels of RF energy that is deemed to
comply without maximum permissive exposure evaluation (MPE).
FCC Warning
This equipment has been tested and found to comply with Part 18 of the FCC
Rules.
- The interference potential of the device or system.
- Maintenance of the system.
- Simple measures that can be taken by the user to correct interference.
- For RF lighting devices, provide an advisory statement, either on the product packaging or with other user documentation, similar to the following:
This product may cause interference to radio equipment and should not be installed near maritime safety communications equipment or other critical navigation or communication equipment operating between 0.45-30 MHz.
FCC Radiation Exposure Statement
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Supplemental Information
technical discussion of usable distance and the number of serviceable receivers
- Serviceable Distance
- The operable range of the receiver is 0.01mW～300mW in power. Refer to the table below for the theoretical distance range. The operable distance is approximately 50mm～6000mm. （The minimum required power to activate the receiver is 0.01mW and 300mW is the maximum allowable power to the protection circuitry.）

- Serviceable Receivers
- Taking the 3dB(1/2) beam width (at around 120 degrees) into consideration, the covered area at the max distance from DUT is 42m2 (6×√(1/2)＝4.24m) as shown below. The receivers placed on the blue circle plain can be activated because the electromagnetic field strength at 6m squarely from DUT and the field strength at the location where the gain is half and the distance is √(1/2) are equivalent.
- Even if placing the receivers 0.327m (the wavelength of 918MHz) apart to avoid unwanted interferences, the required area is 0.327^2×300=~32m2.42m2 area shown below covers 32m2, and more than 300 receivers can be activated simultaneously.
