RS-232C Port Communications Settings
The following settings are effective after transfer to the PC.
If the CPM2A CPU Unit’s Communications Switch is ON, communications through the CPM2A’s RS-232C port are gov-
erned by the default settings (all 0) regardless of the settings in DM 6645 through DM 6649.
If pin 2 of the CPM2C CPU Unit’s DIP switch is ON, communications through the CPM2C’s RS-232C port are governed
by the default settings (all 0) regardless of the settings in DM 6645 through DM 6649.
DM 6645
00 to 03
Port settings
0: Standard (1 start bit, 7 data bits, even parity, 2 stop bits, 9,600 bps), Host Link unit
number: 0
1: Settings in DM 6646
(Any other setting will cause a non-fatal error and AR 1302 will turn ON.)
226
04 to 07
CTS control setting
0: Disable CTS control; 1: Enable CTS control
(Any other setting will cause a non-fatal error and AR 1302 will turn ON.)
08 to 11
Link words for 1:1 data link
0: LR 00 to LR 15 (Any other settings are ineffective.)
12 to 15
Communications mode
0: Host Link; 1: No-protocol; 2: 1:1 PC Link Slave; 3: 1:1 PC Link Master; 4: NT Link
(Any other setting causes a non-fatal error and turns ON AR 1302.)
