To protect sequences with the recessed switch

(HP 54656A only)

The HP 54656A RS-232 Test Automation Module has a small recessed switch

between the 9-pin RS-232 connector and the RJ-45 output lines connector.

Flipping the switch towards the label side of the module protects the

sequences from being changed by the operator. When the Sequence Admin

softkey is pressed with the protection on, a warning message "Sequence

Admin Protected" is displayed.

When you want to edit the sequence again, flip the switch away from the

label side to regain access to the Sequence Admin menu.

To protect the sequences

Once the whole test sequence and masks are properly set up, you may not

want to have any other people change it. Protection of the test sequence and

the mask templates are provided by both modules. Note that the protection

does not include the protection of the two nonvolatile trace memories in the

module.

For the HP 54656A RS-232 Test Automation Module, the protection is in effect

when either the recessed switch is flipped to the protected position or the

protection command is issued through the RS-232 port.

A small piece of sealing label can be used to cover the small opening that

accesses the protection switch. A more complete protection can be

accomplished by sending commands to the Test Automation Modules through

the communication ports.
