Parameters for Host Link and RS-232C Communications
8-2-1 Standard Communications Parameters
The settings in DM 6645 and DM 6650 determine the main communications pa-
rameters, as shown in the following diagram.
The settings in bits 00 through 07 and bits 12 through 15 are valid only when pin
5 on the CPU's DIP switch is OFF. Bits 08 though 11 are valid only in a PC set as
the master for a 1:1 link.
DM 6645: RS-232C port
DM 6650: Peripheral port
Communications mode
0: Host link
1: RS-232C
2: One-to-one link slave
3: One-to-one link master
4: NT link
Link words for one-to-one link
0: LR 00 to LR 63
1: LR 00 to LR 31
2: LR 00 to LR 16
Port settings
00: Standard communication parameters

(defaults: standard communications parameter and
Host Link mode)
The standard communications parameters are as shown in the following table.

Start bits
Data length
Stop bits
Parity
Baud rate
Be sure to set the proper communications mode.
If the above parameters are acceptable, set the rightmost two digits (port set-
tings) to 00. To change the parameters, use the setting described next.
