Passwords

The fields on the Passwords page are for entering and verifying administrator and

user passwords. Passwords are case sensitive and are limited to 12 upper case and

lower case alphanumeric characters. Each password must be entered twice; once in

the Password field and then again in the Re-enter Password field. Characters in

these fields are masked by asterisks (*****).

The following characters are invalid in passwords: {space} + ~ @ = ‘ [ ] {

} < > ’ “ ; : | \ and ?.

If you do not want to password protect an access level, leave the Password field

and the Re-Enter password field blank. After entering the desired password in both

fields, click the Submit button.

As shown in figure 6-5 below, password-protected connections allow two levels of

protection: administrator and user. Administrators have full access to all MPX 423 A

switching capabilities and editing functions. Users can only create ties, set video

and audio mutes, and view all settings, with the exception of passwords.

The MPX 423 A does not feature preset options.

Please keep in mind that

• connecting via an Ethernet connection, entering SIS commands (see chapter 5,

Programmer’s Guide) or using the Windows

-based control program to access

the MPX is password protected.

• connecting via the RS-232 port, entering SIS commands or using the

Windows-based control program to access the MPX is not password

protected.

An administrator password must be created before a user password can be

created.

To clear an existing password so that no password is required, delete the asterisks in

the Password field and place a blank space in the field. Click the Submit button.

Firmware upgrade page

The Firmware Upgrade page (figure 6-6) provides a way to replace the firmware

that is coded on the switcher’s control board without taking the switcher out of

service, opening the switcher enclosure, and replacing the firmware chip.
