6.S-Registers

6.1Introduction

Certain Command Mode configurations are stored in memory registers called, S-Registers. The S command is used to assign a value to, and to read the current value of an S-Register. To assign a value to an S- Register, enter the letter S, followed by the S-Register number and an equals sign (=), and then a decimal response to the message “ENTER THE NEW VALUE IN DECIMAL FORMAT”. To read an S-Register value, enter the letter S followed by the S-Register number and a question mark (?), then hit RETURN. To verify that the S-Register value was entered correctly, enter for example, ATS8? and hit RETURN. You should receive a response of the assigned value given to that S-Register. Refer to Section 6.2, Reading and Assigning S-Register Values.
