The PC Setup settings that are required depend on whether a peripheral port or
an RS-232C port is used.
Settings for RS-232C Port
Note If SW1 on the front panel of the CPU Unit is ON, the RS-232C port will operate
with the default settings regardless of the settings in DM 6645 to DM 6649.
Port settings
0: Standard (1 start bit, 7-bit data, 2 stop bits, even parity, 9,600 bps; Host
Link unit number: 0)
1: Settings in DM 6646
(Other settings will cause a non-fatal error, the default setting will be used,
and AR 1302 will turn ON.)
CTS control settings
0: Disable; 1: Set
Link words for 1:1 PC Link
0: LR 00 to LR 15; Other: Not effective
Communications mode
0: Host Link (default setting); 1: RS-232C (no-protocol); 2: 1:1 PC Link Slave;
3: 1:1 PC Link Master; 4: 1:1 NT Link
(Other settings will cause a non-fatal error, the Host Link setting will be used,
and AR 1302 will turn ON.)
Baud rate:
00: 1,200 bps 01: 2,400 bps 02: 4,800 bps 03: 9,600 bps 04: 19,200 bps

Transmission delay (Host Link)
0000 to 9999 (BCD): Set in units of 10 ms, e.g., setting of 0001 equals 10 ms
(Other settings will cause a non-fatal error, the default setting (0000) will be
used, and AR 1302 will turn ON.)
00 to 31 (BCD): Node number (Host Link)
(Other settings will cause a non-fatal error, the default setting (00) will be
used, and AR 1302 will turn ON.)
Start code enable (RS-232C)
0: Disable; 1: Use start code in DM 6649.
End code enable (RS-232C)
0: Disable (number of bytes received)
1: Use end code in DM 6649.
2: CR, LF
(Other settings will cause a non-fatal error, the disable setting will be used,
and AR 1302 will turn ON.)
