Communications Functions Section 1-9
Note If an out-of-range value is set, the following communications conditions will
result. In that case, reset the value so that it is within the permissible range.
Communications mode: Host Link
Communications format: Standard settings
(1 start bit, 7-bit data; even parity, 2 stop bits,
9,600 bps)
Transmission delay: No
Node number: 00
RS-232C Port Settings When the RS-232C port is used to conduct no protocol communications, the
following settings must be made from the peripheral device to DM6645 to
DM6649 in the SRM1.
DM 6654 00 to 07 Start code (effective when bits 08 to 11 of DM6650 are set to 1.)
00: 256 bytes
01 to FF: 1 to 255 bytes
As
required
08 to 15 End code (no protocol)
When bits 12 to 15 of DM6653 are set to 0:
00: 256 bytes
01 to FF: 1 to 255 bytes
When bits 12 to 15 of DM6653 are set to 1:
Setting: 00 to FF (binary)
