The 0–F bits of the rotary DIP switch indicate device numbers1–16 during RS485 communication. (Switch 0 indicates device number 16; switch 1 indicates device number 1,and so on. Switch F indicates device number 15). You can rotate the 0–F bits of the rotary DIP switch tocorresponding positions to set device numbers, and then restart the control panel to make the setting take effect.Address numbers cannot be repetitive.4.6 USB UpgradeThe USB slot is primarily used for control panel upgrade, the following describes how to use it:1) Create a [Udisk] folder in the USB disk and save the upgrade file in the folder.2) When the control panel works normally, insert the USB disk, press the Reset button and hold it for 1 to 5seconds (the RUN indicator flashes), and release it.3) The RUN indicator keeps flashing during the upgrade (you must not cut the power or remove the USB disk).The machine will restart automatically after upgrade operation succeeds.4) If upgrade operation fails, the machine will return normal.
