CS1W-SCU@1-V1
Serial Communication Unit
Support Protocol Macros, Host Link
Communications, and 1:N NT Links
• Mount up to 16 Units (including all other CPU Bus
Units) on CPU or Expansion Racks. Ideal for sys-
tems that required many serial ports.
Function
The SCU21 and SCU41 CPU Bus Unit can be used to increase the
number of serial ports (RS-232C or RS-422A/485) two at a time. The
SCU21 provides two RS232C ports, the SCU41 has one RS232C port
and one RS422/RS485 port. Specify Serial Gateway, Protocol Macros,
Host Link Communications, or 1:N NT Links separately for each port.
With the CJ Series, you can easily provide the right number of serial
ports for your system.
