To the International Sales ManagerWe an Australian Systems integrator and would like a scrolling LED display which has the following features: * auto brightness control * 7 rows by 120 LEDs long * daisy chaining with RS485 communications for 5 rows of signs * Software commands to control the sign (can you send the command set so that we can evaluate the control methods?)If the command set is OK we will purchase one for testing then purchase 6more to do field trials in the Australian sun!I look forward to receiving your comments.Best Regards,Richard rfid, led display, access controller LED displays
