Kystar MFC630 Multi-function Card Description

The Kystar MFC630 is a multi-function accessory for LED display systems that enables centralized power control through a simple serial (USB-to-serial) command set. It provides 8 independent relay channels (CH1–CH8) that can be switched individually or in batches, supports a dedicated “central control mode” for third-party controllers, and returns clear status/OK/ERROR responses to ensure reliable automation.

Product Features:
• 8 relay channels (CH1–CH8) for on/off control of multiple power circuits
• Custom ASCII AT-command interface; uppercase, no spaces, “#” as command terminator
• USB-to-serial communication; compatible with common serial debugging tools
• Central control mode disables host power management until exit; leave with AT+EXIT or auto-exit next day
• Single-channel set/read: AT+CHx=1 / AT+CHx=0 / AT+CHx=
• Batch set/read: AT+CHA=… (write multiple channels at once) and AT+CHA=? (returns 8 values)
• Clear responses: “OK/ERROR” on writes; “x,x,x,x,x,x,x,x” (0=open, 1=closed) on reads
• Documented command set version V1.00 (2019-08-13)
