Figure 1.5 BASIC Development Software Interface (RS-232)
In this configuration, the serial port on the personal computer is
connected to port PRT1 on the module. The personal computer
communicates with the module through terminal emulation over an
RS-232 interface. Port PRT1 must be configured as the program port.
See Chapter 3 for additional information on port configuration.
BASIC Development Software Interface (DH485)
In this configuration, the serial port on the personal computer
interfaced with port DH485 on the module through a 1747-PIC
interface/converter. Port DH485 must be configured as the program
port with DH485 protocol.
See Chapter 3 for additional information on port configuration.

IMPORTANT
When using the BASIC development software to
interface with the RS-232 port of the module, PBASE
must be configured for RS-232 communication
through the configuration and terminal selection
menus. Refer to the BASIC Development Software
Programming Manual, publication 1746-PM001, for
additional information.
