This simple application demonstrates
use of a pair of DS-WCM’s. The local WCM connected to a PC via
the RS232 interface cable (DS-W232CAB) running the downloadable PC-WCM
terminal1. The remote WCM is set to autonomous
mode drives the HS-300 servos on the TR1 Rover modified for continues
motion and a “Little Grip Kit” (using two unmodified HS-300
servo).
This allows a remote controlled solution without the need for a separate
microcontroller.
The local WCM (connected to the PC) should have both its address jumpers
on (address 00), and the remote WCM should be set up for autonomous
mode (see WCM data sheet).
Download PC to WCM Interface software
WCM
Win98SE interface for Windows 98 & below (1.5Mb)
WCM
interface for XP, NT, 2000 & Windows ME (2.1Mb)
PC-WCM Terminal Set-up
Enter the correct COM port and open it.
WCM address = 00 (match address jumpers of local WCM)
Remote Node Address = 255 (autonomous mode).
Local Node Address = 1
Adjust Timeout Value as required.
Data to remote = 0
Local IO Direction = 0
Local IO Data = 0
Remote IO Data = 0
Servo Manipulation
Modified servo positions can differ from one to another so some experimenting
is needed to find the correct number to send to produce a stop, go
forward, backward, right or left condition for the wheels and also
to control grip position for the “Little Grip Kit”.
Adjust servos 1 – 8 to produce the required servos motion.
Ensure that separate power is supplied for the servos on the remote
WCM through the RS232 COMs port.
