The last function in the BAUD subgroup is “exit.” When the exit function is displayed, you can press up
on the SET/NEXT switch to leave the BAUD subgroup and display PAR, the next SIO function. To exit
the SIO group altogether, press up or down on the GROUP switch.
5.1.1.5 Parity Mode Selection
To display and change the current parity mode, perform these steps:
1. Press down repeatedly on the GROUP switch until SIO appears.
2. Press down on the SET/NEXT switch to display PAR.
3. Press up once on the SET/NEXT switch. The display now shows SPACE, which is the first of four
available parity modes. If parity mode is set to SPACE, every parity bit is set to zero.
4. Press down on the SET/NEXT switch additional times to see the other available modes:
• Mark
• Even
• Odd
If parity mode is set to Mark, every parity bit is set to one. If parity mode is set to Odd or Even,
parity bits are set to create odd or even parity for each data byte. The green (top) indicator light
turns on when the display is the same as the current setting, and the red (bottom) indicator light
turns on when the display is not the same as the current setting.
5. To change the current parity setting, advance the display to the desired setting and press up twice
on the SET/NEXT switch. After the first press, the green (top) light blinks, indicating a change is
about to be made. After the second press, it turns on continuously, indicating the display matches
the current setting.
The fifth function in the PAR subgroup is exit. When the exit function is displayed, you can press up on
the SET/NEXT switch to leave the PAR subgroup and display Lock, the next SIO function. To exit the
SIO group altogether, press up or down on the GROUP switch.
5.1.1.6 Lock Function Use
The Lock function locks and unlocks the remote port. When the remote port is locked, setup changes
cannot be made remotely, preventing accidental or unauthorized system setup changes through the
remote port.
To unlock a multiplexer via the remote port, you must send the proper command and password.
During setup, you select a password, which can be any collection of letters and numbers up to 16
characters in length. The
Use LOCK and UNLOCK Commands subsection of Section 5.2.3.2 describes
the use of locking commands and passwords. The lock function has no effect on local operation; a
multiplexer can be unlocked locally (using the GROUP and SET/NEXT toggle switches) even if its
password has been lost.
To access the Lock function directly, perform these steps:
1. Press down repeatedly on the GROUP switch until SIO appears.
2. Press down on the SET/NEXT switch until Lock is displayed. (As mentioned previously, you can
also access the Lock function from the PAR subgroup by displaying its exit function and pressing
up on the SET/NEXT switch.)
3. When the display shows Lock, the green (top) indicator light turns on if the multiplexer remote
port is locked, and the red (bottom) indicator light turns on if it is unlocked. To toggle the state of
the remote port from locked to unlocked or unlocked to locked, press up twice on the SET/NEXT
switch.
4. To exit the Lock function and display the BAUD subgroup, press down on the SET/NEXT switch. To
exit the SIO group entirely, press up or down on the GROUP switch.
