*1 Set the host link communications speed at 9600 bps or 19200 bps with the
memory switch at the NT31/NT31C. For details, refer to "Setting the Host Link
Method" (page 176).
*2 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.
The setting methods for each type of unit are described in the following.
