The M4SSER expands the number of serial ports on the M4 Modular Controllers from two to four. Intrinsically, the M4’s UART can support four communication ports. However, the M4 base unit provides connections for only two ports (COM0 and COM1). The M4SSER allows the user to take advantage of the two remaining ports (COM2 and COM3). The M4SSER can be used with any of Opto 22’s M4 Modular Controllers except the SNAP-LCM4.
