Set the CPU Bus Unit settings directly from a Programming Device (e.g. SYS-
MAC support software).
For details on the CPU Bus Unit settings, refer to the SYSMAC CVM1/CV-
series Host Link Unit Operation Manual (W205-E1-@).

PLC Setup
When connecting to a CVM1/CV-series CPU Unit, set the following communi-
cations conditions for the PLC Setup.
Set the host link communications speed at 9600 bps or 19200 bps with the
memory switch at the NT31/NT31C. For details, refer to 6-7-2 Setting the Host

Set the host link communications speed at 9600 bps or 19200 bps with the
memory switch at the NT31/NT31C. For details, refer to 6-7-2 Setting the
Host Link Method (page 161).
The 1-to-N setting enables BCC (Block Check Character). It is not actually
possible to connect more than one NT31/NT31C in a single host link.

• Unit # (SW3, SW4)
• I/O port selection (selector switch)
• CTS selection (DIP SW2 and SW3)
• Communications condition setting (DIP SW1)
Set this to RS-232C.
Set SW2 or SW3 to ON. (Set this always to 0 V.)
To use communications port 1, set SW2. To use
communications port 2, set SW3.
When using communications port 2, set
these switches to 0.
Set this switch to OFF.
Communication is executed in accordance with the
CPU bus unit system settings made at the PLC. The
initial values for the system settings are as follows.
- Communications speed: 9600 bps
- Parity: Even
- Xon/Xoff control: Not executed
- Communications method: Full duplex
- Stop bits: 2 stop bits
- Data length: 7 bits
