Also, if the hub is positioned close to acontrol board, we recommend using it at a distance of 10 m or less.(Note 4): The LAN port is insulated from the internal circuit.* When using it as tool port, the GT cannot communicate with multiple tools (PC) including USB port simultaneously. SD memory cardItem SpecificationsSupport media (Note 1)SD memory card, SDHC memory card(The manufacturer that the operation check has done: PanasonicCorporation)Supported format standard Conforms to SD standard(Please format with format software for SD memory cards.)(Note 1): Check the usable temperature range of a SD memory card to be used before use.Cautions on handling a SD memory cardThe data saved in the SD memory card may be lost in the following cases. We assume noresponsibility whatsoever for the lost of saved data.1) When a user or third party used the SD memory card incorrectly.2) When the SD memory card was affected by any static electricity or electrical noise.3) When the SD memory card was removed or the power supply of the GT unit was turned offwhile data was being read, written or deleted to/from the SD memory card.* It is recommended to save important data in another media for backup.
