RS-232 Configuration
Configure your PC for 8-bit data, one start-bit, one stop-bit, full duplex and no parity. The baud rate
for the RS232 communication can be selected by setting the proper switch configuration on the front
panel according to the table below.

Handshaking Modes
The RS232 main port can be configured for hardware and software handshaking. For Hardware
Handshaking, set the HSHK switch to ON. In this mode, the RTS and CTS lines are used. The CTS
line will go high whenever the DMC-2x00 is not ready to receive additional characters. The RTS line
will inhibit the DMC-2x00 from sending additional characters. Note, the RTS line goes high for
inhibit. The handshake should be turned on to ensure proper communication especially at higher baud
rates.
Software handshaking can be enabled by setting the XON switch to ON. In this mode, the controller
will generate / accept XON and XOFF characters to control the flow of characters to / from the
terminal. The controller uses the hex value $13 for the XOFF character and the hex value $11 for the
XON character.
The auxiliary port of the DMC-2x00 can be configured either as a general port or for the daisy-chain
(DMC-2000 only). When configured as a general port, the port can be commanded to send ASCII
messages to another DMC-2x00 controller or to a display terminal or panel.
