5.3 Waveform Generator (cont’d)

5.3.1 Login Screen – User Identification Input 

(cont’d)

Standard users are intended to be everyday users of the system, 
who only have the ability to run pre-defined pulse waveform 
protocols from an access list as determined by the administrator. 
The administrator may grant a standard user the ability to 
modify an already defined protocol, but not to add/remove 
protocols.

AgilePulse

 is factory configured with only the “admin” account 

available. By default no password is defined so the user can 
enter the system with parameters matching that of Figure 5-4 
on first login. The password may then be changed from the User 
account screen in Setup section. The most recently logged in 
user will be displayed in the User Name field on startup.

To enter User names and Passwords, touch the Change buttons 
to activate a virtual keyboard.

User name:

Enter the user’s name to login

Password:

Enter the password associated with the user 
account. Password entry is masked with “*” 
characters in order to provide increased security.

When the User name and Password have been entered, touch 
OK to log in.

5.3.2 Welcome Screen – Identification Input

An opening screen (Figure 5-5) allows input of key experimental 
information after the initial system log in. Information is entered 
by a virtual keypad. The purpose of this screen is for the USER 
(Researcher) to enter the Experiment ID, Transfectant and 
Electrode ID.

All three parameters are set by user selected input. Touching a 
text field box highlights it blue and allows modification. Use the 
available touch screen keypad to enter up to 15 characters for 
each. Alternatively, a USB keyboard may be plugged into one 
of the front panel USB connectors and used to edit the ID fields 
manually. This screen cannot be operated from the foot pedal (ID 
fields cannot be selected or edited). The following pulse delivery 
screen may be operated by either the touch screen or by the 
optional foot pedal depending on the specification.

After verifying the identifications are correct go to the delivery 
screen by touching NEXT.
