The most significant difference between wireless link and wired link is that the wireless one is free from
the cable installation and operating under the regulated distance. Once the wireless solution is designed in,
product or device may apply in various phases, floors and high-elevated locations with appropriated power
saving solution and installation.
RFMO-0201 is a complete RF board with a protocol-on-micro-processor structure and without extra driver
installation, which is designed to replace the cable between the PC and the peripheral RS -232 equipments
and make data transmitted over radio. RFMO-0201 uses 433.92 free-licensed ISM band. RFMO-0201 is
designed to interface with RS -232 port, with its featured compact size it can be installed or embedded in
various handheld devices.
s Note 1: Max 2 characters are allowed in every single transmission.
s Note 2: This product is utilized for control purpose. Continuous data transmission will not be adopted.
s Note 3: The duration of each transmission shall not be greater than one second and the silent period
between transmissions shall be at least 30 times the duration of the transmission but in no case
less than 10 seconds.

Important Notice
Devices operated under the provisions of this paragraph shall be provided with a means for automatically
limiting operation so that the duration of each transmission shall not be greater than one second and the silent
period between transmissions shall be at least 30 times the duration of the transmission but in no case less
than 10 seconds.
Federal Communication Commission Interference Statement
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 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 complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
Information to User – The users manual or instruction manual for an intentional or unintentional radiator shall
caution the user that changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
