Omron C200HE ユーザーズマニュアル

The default values are assumed for all of the PC Setup (i.e., the RS-232C port is
used in Host Link mode, the node number is 00, and the standard communica-
tions parameters are used.)

00100 SR 26405

If SR 26405 (the Transmit Ready Flag) is ON
when IR 00100 turns ON, the ten bytes of
data (DM 0000 to DM 0004) will be trans-
mitted.

This section explains RS-232C communications. The TXD(––) and RXD(––)
instructions can be used with RS-232C communications to output data to a print-
er, input data from a bar code reader or transmit Host Link commands to other
devices equipped with an RS-232C port.

The following diagram shows the RS-232C connection when the RS-232C port
is used in RS-232C mode (no protocol).

an RS-232C
port

The following parameters in the PC Setup must be set in advance to enable
RS-232C mode communications through the RS-232C or peripheral ports.

Communications Mode
Set the communications mode to RS-232C mode.

RS-232C port:  Set bits 12 through 15 of DM 6645 to 1.
Peripheral port:  Set bits 12 through 15 of DM 6650 to 1.

Standard Port Settings
Standard settings or custom settings can be used for the RS-232C and peripher-
al ports. Refer to page 420 for details on the standard communications settings.

Custom Port Settings
Standard settings or custom settings can be used for the RS-232C and peripher-
al ports. Refer to page 421 for details on custom communications settings.
