Peripheral Port Settings
The following settings are effective after transfer to the PC.
DM 6650 00 to 03 Port Settings (Host Link or No-protocol mode)
0: Standard (1 start bit, 7-bit data, even parity, 2 stop bits, 9,600 bps)
1: Settings in DM 6651
04 to 07 CTS Control Settings (Host Link or No-protocol mode)
0: Disable; 1: Set
08 to 11 Not used.
12 to 15 Communications Mode (when bits 00 to 03 are set to 1)
0: Host Link; 1: No-protocol
When a Programming Console is connected to the peripheral port, turn OFF pin 7 of
the CPU Unit's DIP switch. (Pin 5 and the PC Setup settings are disabled in this case.)
When connecting a personal computer to the peripheral port for use as a Programming
Device, turn pin 7 ON and set the communications mode to "Host Link." When these
settings have been made and the personal computer is set for peripheral bus opera-
tion, the CPU Unit's peripheral port communications mode will automatically switch to
peripheral bus mode.
DM 6651 00 to 07 Baud Rate (Host Link, peripheral bus, or No-protocol mode)
00: 1.2 kbps, 01: 2.4 kbps, 02: 4.8 kbps, 03: 9.6 kbps, 04: 19.2 kbps

DM 6652 00 to 15 Transmission Delay (No-protocol or Slave-initiated Host Link communications only)
0000 to 9999 (BCD): Set in units of 10 ms, e.g., a setting of 0001 equals 10 ms
DM 6653 00 to 07 Node Number (Host Link): 00 to 31 (BCD)
08 to 11 Start Code Enable (No-protocol)
0: Disable; 1: Set
12 to 15 End Code Enable (No-protocol)
0: Disable (number of bytes received)
1: Set (specified end code)
2: CR, LF
DM 6654 00 to 07 Start Code (No-protocol)
00 to FF (hexadecimal)
08 to 15 When bits 12 to 15 of DM 6653 are set to 0:
Number of Bytes Received
00: Default setting (256 bytes)
01 to FF: 1 to 255 bytes
When bits 12 to 15 of DM 6653 are set to 1:
End Code (No-protocol)
