DM 6646
00 to 07 Baud rate
00: 1,200 bps; 01: 2,400 bps; 02: 4,800 bps; 03: 9,600 bps; 04: 19,200 bps

(Any other setting specifies standard settings (1 start bit, 7 data bits; even parity, 2 stop
bits, 9,600 bps), causes a non-fatal error, and turns ON AR 1302.)
DM 6647 00 to 15 Transmission delay (0000 to 9999 BCD sets a delay of 0 to 99,990 ms.)
(Any other setting specifies a delay of 0 ms, causes a non-fatal error, and turns ON
AR 1302.)
DM 6648 00 to 07 Node number (Host Link)
00 to 31 (BCD)
(Any other setting specifies a node number of 00, causes a non-fatal error, and turns
ON AR 1302.)
08 to 11 Start code selection for no-protocol communications
0: Disables start code; 1: Enables start code in DM 6649
(Any other setting disables the start code, causes a non-fatal error, and turns ON
AR 1302.)
12 to 15 End code selection for no-protocol communications
0: Disables end code; 1: Enables end code in DM 6649; 2: Sets end code of CR, LF.
(Any other setting disables the end code, causes a non-fatal error, and turns ON
AR 1302.)
DM 6649
00 to 07 Start code (00 to FF)
(This setting is valid only when bits 8 to 11 of DM 6648 are set to 1.)
08 to 15 When bits 12 to 15 of DM 6648 set to 0:
Sets the number of bytes to receive. (00: 256 bytes; 01 to FF: 1 to 255 bytes)
When bits 12 to 15 of DM 6648 set to 1:
Sets the end code. (00 to FF)
