geosurv T500L Long Distance Wireless Data Transreceiver Module

Platform Construction

The platform construction method is shown in the figure above

1. The MMCX line conducts the RF signal to the test instrument.
2. Use DC power supply 7.5V current limiting 2A.
3. Connect the DB9 serial cable to the PC.
4. Use the SSCOM serial port test software or other serial port debugging software on the computer (the switch of the test kit should be turned to the position shown in the figure).

  • pwr l (using low power 3W)
  • 0123456789 (Input send data at least 600 bytes)
• （b） Data pattern test methods

1. Select a protocol
2. Select the transmission frequency
3. Select high and low power
4. Enter send data 0123456789 (at least 600 bytes)
5. Flip the switch downwards
6. Select scheduled sending
  *  **Note** : When switching configurations, you need to stop the transmission first, and then restart the transmission after all information is configured.

FCC

FCC WARNING:

Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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.

This equipment has been tested and found to comply with the limits for a Class B digital device, under 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 under 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 the receiver.
• Connect the equipment to 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.

FCC RF EXPOSURE STATEMENT:

This equipment complies with FCC radiation exposure limits set forth for a controlled environment. Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01.

List of applicable FCC rules

• CFR 47 FCC PART 15 SUBPART C/E has been investigated. It applies to the modular.

Specific operational use conditions

• This module is stand-alone modular. If the end product will involve Multiple simultaneous transmitting conditions or different operational conditions for a stand-alone modular transmitter in a host, the host manufacturer has to consult with the module manufacturer for the installation method in the end system.

Limited module procedures

• Not applicable

Trace antenna designs

• Not applicable

RF exposure considerations

• To maintain compliance with FCC’s RF Exposure guidelines, This equipment should be installed and operated with a minimum distance of 30cm from your body.

Antennas
