4 FAQ
Q Why does not the baud rate change take effect immediately after setting A Restart the module to take effect after baud rate setting
Q Why there is no response when entering DFU mode
A In DFU mode, the baud rate of the serial port is 115200. Check whether the
baud rate of the serial port tool is correct. RHF0M0x5 module does not need to
be restarted
Q:Node sending data completed, but the server did not receive data
A:
- Check whether gateway and node devices are registered to the server
- Check whether the working band of the node and the gateway matches, and whether the working channels matches
- Checking whether the working mode and working type of the node are consistent with the device information registered by the server
- Check whether the node supports the set working frequency band
- Check whether the antenna of each node and gateway is correct
ORIGINAL EQUIPMENT MANUFACTURER (OEM) NOTES
The OEM must certify the final end product to comply with unintentional radiators (FCC Sections 15.107 and 15.109) before declaring compliance of the final product to Part 15 of the FCC rules and regulations. Integration into devices that are directly or indirectly connected to AC lines must add with Class II Permissive Change.
The OEM must comply with the FCC labelling requirements. If the module’s label
is not visible when installed, then an additional permanent label must be
applied on the outside of the finished product which states: “Contains
transmitter module FCC ID: 2AJUZ0M0E5”. Additionally, the following statement
should be included on the label and in the final product’s user
manual: “This device complies with Part 15 of the FCC
Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interferences, and
(2) this device must accept any interference received, including interference
that may cause undesired operation.”
The module is limited to installation in mobile or fixed applications. Separate approval is required for all other operating configurations, including portable configuration with respect to Part 2.1093 and different antenna configurations.
A module or modules can only be used without additional authorizations if they have been tested and granted under the same intended end-use operational conditions, including simultaneous transmission operations. When they have not been tested and granted in this manner, additional testing and/or FCC application filing may be required. The most straightforward approach to address additional testing conditions is to have the grantee responsible for the certification of at least one of the modules submit a permissive change application. When having a module grantee file a permissive change is not practical or feasible, the following guidance provides some additional options for host manufacturers. Integrations using modules where additional testing and/or FCC application filing(s) may be required are: (A) a module used in devices requiring additional RF exposure compliance information (e.g., MPE evaluation or SAR testing); (B) limited and/or split modules not meeting all of the module requirements; and (C) simultaneous transmissions for independent collocated transmitters not previously granted together.
This Module is full modular approval, it is limited to OEM installation ONLY. Integration into devices that are directly or indirectly connected to AC lines must add with Class II Permissive Change. (OEM) Integrator has to assure compliance of the entire end product include the integrated Module. Additional measurements (15B) and/or equipment authorizations (e.g. Verification) may need to be addressed depending on co-location or simultaneous transmission issues if applicable. (OEM) Integrator is reminded to assure that these installation instructions will not be made available to the end user
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference. (2) This device must accept any interference received, including interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more
of the following measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and receiver.
– Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
– Consult the dealer or an experienced radio/TV technician for help
– This device and its antenna(s) must not be co-located or operating in
conjunction with any other antenna or transmitter.
NOTE: The manufacturer is not responsible for any radio or TV interference
caused by unauthorized modifications to this equipment. Such modifications
could void the user’s authority to operate the equipment.
