Page 7: Rs485 To 2X Rs232 Fallback Switch
CMU 100 - RS485 to 2x RS232 fallback switch RS485 TO 2x RS232 FALLBACK SWITCH DESCRIPTION Fallback switch is communication device that switches data between two master ports and one slave port. It is intended to connect one device (RTU) to two master devices (PC). This device contains one RS485 interface (master) and two RS232 interfaces two (slave) ports. -
