accordingly after the initial power on sequence is completed. Refer to the Startup Configuration command (SC) for 
exceptions. 

All settings can be changed via the serial control port; however, parallel port settings will in general override the 
serial port settings.  However, configurations can only be saved from the serial control port.  Changes made by the 
user via either method are NOT saved unless the Save command (SV) is issued from the serial control port before 
powering down. 

 

*SV Note:

  Users may save internal clock and data in presets for bench debug use BUT 

on a power up or when a 

hardware

 preset is restored, 

CS

 and 

DS

 will be forced to 

0

 

(external clock and data). This action prevents a transmitter from powering up or 
changing hardware presets and being set to internal clock and/or data. The ONLY way to 
restore CS and/or 

DS

 as 

1

 from a saved configuration is by executing the 

RC

 command 

or by having the -ID option available on the unit. 

 

Note:

 All user commands do not apply to all transmitters. Command availability varies depending on the options 

ordered and any project specific customization applied. Questions? Please call Quasonix for assistance.
