Please Help I just purchased a servo controller but it don't want to work. I have tried To identify firmware version number and set the baudrate. I have a steady red led and a blinking green led on the servo controller also the servo is locked I assume in mid range I am using #15 pin for serout. what am I doing wrong??· Hank

·· Since you are using a BS2sx, have you set the baud rate parameters correct for a BS2sx?· The ones in the demo code are for the BS2, which is different.· The help files can tell you the correct baud rate parameters for your Stamp Module.

Baud parameters get people every time.· I have this block of code in my standard template that "fixes" the baud parameter for the BASIC Stamp module I happen to be using.

Follow-up: For the PSC, you might want to define two baud contants:

BaudSlow······· CON···· T2400 + Open
BaudFast······· CON···· T38K4 + Open
