Set Password
This option permits you to enable or disable the
Monitor’s password protection. You may also use this
option to change the current password.
Selecting Set Password displays the Set Password
screen. The cursor is positioned next to
ENABLE/DISABLE PASSWORD. Press the UP arrow
or DOWN arrow key to toggle between enabled and
disabled password protection. Press SELECT to enter
your choice. If you are choosing to disable password
protection, press SELECT again to confirm your choice.
If you have enabled password protection, the cursor will
be positioned on the first space of the ENTER NEW
PASSWORD line. The labels for several keys will
change to 1, 2, 3 and 4. Press one of the numbered keys
to enter the first digit of the password and advance the
cursor to the next character. Enter the remaining digits.
When you have completed the four character password,
press SELECT to enter it. You will be asked to confirm
the password by repeating the process. If the
confirmation password does not match the new
password, a message will alert you of this and you will
be asked to begin again.
RS-485 Port Configuration
Some parameters of the Monitor’s RS-485 ports may be
configured locally rather than via the Configuration
Tool. This menu item allows you to make changes to the
following items:
ITEM DEFAULT
VALUE
VALID
OPTIONS
Segment
connection A A or B
Modbus address (null) 1 - 247
Baud rate 19,200 1200, 2400, 4800,
9600, 19,200
Parity none none, odd, even
Stop Bits 1 1, 2
Use the UP arrow or DOWN arrow keys to scroll to the
item you wish to change. Press SELECT. Then use the
UP and DOWN arrow keys to adjust the item to the
desired value and press SELECT to enter the change.
The available options are shown to the right of each
field.
Note that the first field, Segment Connection, determines
which Modbus port the remaining fields refer to. On a
single-port version of the Monitor, the Segment
Connection field is always A.
When changes are completed, press BACK to exit.
Auto-Detection for SLT
For factory use only. If you accidentally select this item,
press BACK/EXIT to return to the Setup menu.
Set Date & Time
This option allows you to set the date & time of the
Monitor’s internal clock. The clock is battery powered
and will keep time regardless of whether the Monitor has
control power connected. However, the operating system
does not support automatic time adjustment for Daylight
Savings Time or geographic time zones. The Modbus
Monitor ships from the factory with the real-time clock
set for Eastern Standard Time. Note that military time is
used; i.e., the hours field may have a value of 1 to 24.
To change the date or time, use the UP or DOWN arrow
keys to move to the field you wish to change, then press
SELECT. Now use the UP or DOWN arrow keys to
adjust the field to the desired value. Press SELECT to
enter the changes.
NOTE: If the Monitor is connected to a PMCS system,
the PMCS DDE Server provides time synchronization to
the Modbus Monitor.
Return to Main Menu
Selecting this option returns you the Monitor’s main
menu.
