INTERFACE MODEL 9840 VER 6.0.2
>>Com Address
This item allows you to set the address of this unit used for the RS232 ASCII
command set. Valid values are 1 through 254. If the RS232 multi-drop option is
installed you must be sure that all the attached units have different addresses to
prevent data collisions.
>>Com Baudrate
This sets the baud rate for the RS232 ASCII command set. Available values are: 300,
600, 1200, 2400, 4800, 9600, and 19.2k. Note that the “Special” entry is reserved for
future use.
>>Com Line Feed
This controls whether a line feed is added to each carriage return that is sent out by the
Model 9840 when the RS232 ASCII command set is being used.
>>Retain Tare
This controls whether the most recent tare value is retained through power down of the
unit and used again immediately on power up. Choosing this option will retain tare on
channel A in a single channel unit and both channels A and B in a two-channel unit.
>>RS232 EOT Char
The end of transmission character is a non-visible character (hexadecimal 0x04) that is
sent at the end of each response by the unit to an RS232 command. The character is
sent after the last carriage-return line-feed returned by the unit with one exception:
when the user is viewing channel values with the RS232 command
@123V(item)(unit)(repeat) and sets the value of repeat to 2 (streaming output), the
character is sent immediately prior to the streaming output that the unit will send. The
user can turn this option on or off.
>Display Options
This menu contains options that effect how load or torque, peak, and valley are displayed
and printed. These are listed in a submenu that works exactly like the setup mode main
menu.
>>Filter Select
There are two types of filters available on the Model 9840: Type I, and Type II. Type I
filters are good for removing most kinds of noise but may leave some jitter on the end
digits. Type II filters are more advanced and are optimized for the typical industrial
environment. Both filter types allow you to select from 4 levels of filtering with Level 1
being the least filtering and Level 4 being the most filtering.
The settling time for each of the 4 levels of filtering is shown in the table below
Level 1 2 3 4
Settling Time (seconds) <1 2 10 30
Read Rate (per second) 60 60 30 10
