3.8.2 RS485

IOT-LINK features up-to two optional RS485 ports implemented with MAX13488 transceivers interfaced with i.MX93 UART ports. Key characteristics:

• 2 ສາຍ, ເຄິ່ງ duplex
• ອັດຕາ baud ທີ່ສາມາດດໍາເນີນໂຄງການໄດ້ເຖິງ 3Mbps
• Optional 120 termination resistors controlled by jumpers located behind the back panel

Note: RS485 ports are only present in gateways ordered with the “FARS4” or “FBRS4” ordering options. RA485 ports are mutually exclusive with CAN bus ports

3.8.3 ວັດສະດຸປ້ອນ ແລະຜົນຜະລິດດິຈິຕອນ

IOT-LINK provides three signals which can be used as either digital inputs or outputs. Key characteristics:

• Designed for 24V PLC applications
• Digital outputs maximal output current ­ 1A per channel
• Digital inputs self-powered with current limit

3.8.4 Remote Power CNTL Input

A remote power button can be connected to the CNTL pin on the terminal block. Pressing the button changes the power state of the system. Connect the button between the CNTL pin and common ground pin.

Warning: Connecting the Remote Power Button input to DC voltage ອາດເຮັດໃຫ້ອຸປະກອນເສຍຫາຍ.
*** Only connect the input pin to GND via contact switch ***
