Description: WTU-518 The WTU-518 acquires and stores data coming from the analog or digital sensor plugged on its geophone connector. By WLAN or LAN communication links, the WTU-518 transmits these stored data to recorder or field unit’s equipment. State Of Health are transmitted through the UNITE system via a 2.4GHz radio communication link. 2.
Deployment: IMPORTANT Whenever any connector is unused, put its connector protective cap in place. LEDs Function: Two LEDs flashing in red Two LEDs flashing every 1s in green Two LEDs flashing every 4s in green acquisition not started or issue after TTFF timeout Harvest and acquisition is running. GPS is locked or unlocked. Acquisition is running. GPS is locked.
Configuring the WTU-518: The user has to program WTU-518 parameters. In this version of document, only the GPS, WLAN and radio configuration are described.
Set Radio Regulatory Domain: Use this menu to choose the appropriate maximum radiated output power for compliance with the local regulations of the country in which the radio unit is to be used: • CE for Europe: +13 dBm eirp at 100 kbps and 500 kbps • FCC/RSS for US/Canada: +16 dBm eirp at 100 kbps and 500 kbps Set Radio frequencies: Use this menu to choose one of these sets of frequencies used in the Frequency Hopping Spread Spectrum (FHSS): 2405-2469 hopset #1 : full 2.
Use the Synchro Word key to prevent connection to another Sercel network. The radio packets transmitted with a Synchro Word key cannot be received by a Sercel network configured with another Synchro Word key.
IMPORTANT Prior to connecting any plug, make sure there is no water inside connectors. Electrostatic discharge: Use the following guidelines to provide a static-free repair station that will preclude any ESD-related damage to electronic circuits: • All spare parts (circuit boards and ESD sensitive devices) should be stored and transported in staticshielding bags. • Unless the repair station rests on a conductive floor, chairs or stools should rest on a grounded, rigidtype, static-dissipative floor mat.
