GDA-HLU1 USB adapter for Gicren devices SKU DFR0346 INTRODUCTION GDA-HLU1 is a USB-to-RS485 adapter automatic data direction control for all Gicren standard devices, whose conversion mechanism is "USB <-> UART FT232RL <-> RS485 SP485EEN ", so it can also be used for other general purpose via pin header, such as “USB<->UART”, “USB<->RS485” and ”UART<->RS485”. Taking into account security issues, there are only D+ and D- pins connected to SP485EEN. In other words, the front-end circuit and back-end circuit do not share the same ground in the printed circuit board, but it is recommended to connect them manually to avoid excessive common-mode voltage when you are sure the connection is correct. In addition, the onboard high-quality D-Sub-9Pin-Female, SMT-PH2.0-9Pin, Header-2.54mmPitch-9Pin, fuse and selectable matching resistor make this adapter more flexible and reliable. It could cooperate with Gicren Drivers SoftServo-B10CH Servo Controller/ RC Signal Generator / SoftServo-B24CH Servo Controller/ RC Signal Generator / DRI0037 / DRI0038 directly.
