Unit Selection
In order to select a unit the @ command followed by the address of the unit must be sent.
NOTE: There should be no spaces between the @ and address select.
How to select a unit:
@0
(Unit 0 is selected)
@1
(Unit 1 is selected)
@29 (Unit 29 is selected)
How to get a response from a unit:
@0$ (Carriage Return)
After the $ command, the PCL501(PC) will return a SMC50 + the current version number.
Note: In direct talk mode each command is followed by a carriage return.
The unit communicates in half duplex mode, therefore proper setup of hyper terminal is necessary to view
characters, if characters are to be echoed back to the screen.
