    ﹡Traffic, Personnel positioning and alarm in the well III. How to use HAC-UM Series HAC-UM is a member of HAC series low power data radio modules, which provides RS-232, RS-485 and UART/TTL level interface port for direct connection with PC, RS485 devices, SCM and other UART components kind of applications.
  • Page 5 SHENZHEN HAC TECHNOLOGY CO., LTD. Power supply HAC-UM work with supply voltage +3.3~5.0 DC. By using better ripple factor, HAC-UM transceivers can also share power supply with other equipment. If possible, a voltage-stabilizing chip with 5V voltage is more recommended as the only power supply than Switch power supply.
