If a command is invalid, one of the following error codes is echoed as well as
being displayed on the LEDs.
E33 Unrecognised command or parameters.
E44 Illegal mode or channel number in command.
Commands take effect immediately they are issued. Because of this, if the
settings are being changed from high current Pulsed Output mode to a
Continuous Output mode, it is advisable to set the current values to 0 using the
RC command before changing mode. This prevents overload conditions
occurring.
Any changes made using RS232 commands are not saved permanently
until the AW command has been issued.
