11.7 ACTIONS 11.7.1 DESCRIPTION
LPSO-Link provides a mechanism to perform certain actions on a connected device. When necessary, the
commands sent to a device to carry out these actions will follow ‘Arm’ and ‘Execute’ sequence defined in
GEMODEM protocol. After a user confirmation for an action request, Arm and Execute sequence will be trans-
parent to the user. You can not perform any of the actions before logging in to a device. It is also essential that
you are logged in to the device with the appropriate privilege for performing actions.
11.7.2 ENABLE OUTPUTS
You can enable the device outputs by sending this request. This is an action that follows the Arm and Execute
scheme. This scheme needs a user confirmation before executing the command.
To enable device outputs, click the
Enable Output
item in the
Actions
menu. A message box will be posted
for your confirmation. Choose
OK
to proceed with enabling the outputs of the device. Choose
Cancel
if you
wish to quit from enabling the outputs of the device.
Before logging out of the device, make sure the outputs are enabled.
11.7.3 DISABLE OUTPUTS
You can disable the outputs of a device by sending this request. This action follows the Arm and Execute
Scheme. This needs a user confirmation before executing the command.
To disable device outputs, click the
Disable Output
item in the
Actions
menu. A message box will be posted
for your confirmation. Choose
OK
to proceed with disabling the outputs of the device. Choose the

but-
ton if you wish to quit from disabling the outputs of the device.
If the outputs are in disabled position, the LPSO-Link will inform you during logout.
11.7.4 CHANGE PASSWORD
You can change the password you use to log in to a device from LPSO-Link. Choose the
Change Password
item in the
Actions
menu. A
Change Password
dialog box appears.
Changing the password happens in three steps.
1. First you are asked to enter the old password. That is the password you are currently logged with. Enter
the password and choose the
OK
button. Choose the
Cancel
button to quit the
Change Password
opera-
tion.
2. When you choose
OK
to proceed with changing password, LPSO-Link will post another dialog box asking
you to enter the new password. Enter the new password and choose the
OK
button. Only alphanumeric
characters are accepted for the password. Since the device accepts only upper case letters, all the charac-
ters are changed to upper case before sending to the device. The maximum length of the acceptable pass-
word is 16 characters.
3. For validation purpose, you are prompted to re-enter the new password. This is to take care of any typo-
graphical errors in your entering the password. Enter the new password again and choose the
OK
button.
The passwords are downloaded to the device for change. Any error from the device will be notified to you.
