Windows-compatible BASIC Module Interface Software
(1747-WINBAS)
BASIC Software is a terminal emulation program specifically written for you to interface
to a Rockwell Automation 1746-BAS, 1746-BAS-T, or 1771-DB BASIC module.
BASIC software simplifies the uploading and downloading of BASIC module programs,
as well as backing up and restoring complete module images. BASIC software also
provides debugging tools to aid in troubleshooting BASIC programs while online.
As a terminal emulation program, BASIC software requires either one RS-232 serial
COM port or a DH-485 interface (1784-PCMK, 1784-PKTX, 1784-PKTXD, or
1747-UIC converter) be available on the personal computers. Bridging to the DH-485
network from other networks is not supported.
BASIC software works on personal computers with Windows 98, 2000, NT, and XP
operating systems. RSLinx Classic OEM software must be installed on the personal
computer to communicate to the 1746-BAS module via the DH-485 interface.

(1) If the BASIC Module DH-485 channel is connected to a 1747-AIC Link Coupler, add 0.085 A to the BASIC
module’s power supply loading value @ 24V DC.
(2) If the BASIC Module is connected to any device (for example, DTAM) either directly or through a 1747-AIC Link
Coupler, add the appropriate current loading for the device to the BASIC module’s power supply loading value
@ 24V DC.
