11.4 Local/Remote Operation
For truck scale and similar applications, local/remote support provides function equivalent to that of a
legal-for-trade remote display with keypad. Scale data from the local indicator is also displayed at the remote unit,
and keypad input from the remote allows transactions to be initiated from either the local or remote unit.
To configure for local/remote operation, first set up the local unit (including truck mode and database information,
as required) as an A/D scale. Once the local unit scale has been configured, use the SERIAL menu, serial
commands or
Revolution III to set the serial parameters for local/remote operation as shown in Table 11-7.
Table 11-7. Local/Remote Configuration Parameters

Parameter
Local Unit Remote Unit
Parameter
Value Function
Parameter
Value Function
EDP.INPUT#p CMD Enables receipt of commands
from the remote unit keypad SCALE Configures the remote unit as a
serial scale receiving weight
data from the local unit
EDP.STREAM#p LFT Streams local unit weight data to
the remote unit KEYPAD Streams commands from the
remote unit keypad back to the
local unit
EDP.BAUD#p 115200 preferred; local and remote values must match
EDP.ECHO#p OFF — OFF —
EDP.RESPONSE#p ON — ON —
In the listed serial commands, p represents the serial port number. For units without a serial expansion card, Port 4 is
recommended for local/remote configuration.
Remote unit only: Once the serial parameters are set for the remote unit, return to the SCALES menu to finish
configuring the remote unit as a serial scale. Under CONFIG, drop down and use the
right or left navigation key to
select the serial port (PORT 4 or PORT 7) used to receive weight data from the local unit. (See also Section 3.1.3
on page 19.)
11.5 Custom Stream Formatting
Each port can be independently configured to stream a default frame format or can be customized to stream a
user-defined format. Custom formatting is very similar to the standard print formatting described in Section 6.0 on
page 52.
Table 11-8 on page 103 lists the format identifiers used to configure a custom stream format.
Format Identifier Defined By Description
<P[G | N | T]> STR.POS#1
STR.NEG#1 Polarity. Specifies positive or negative polarity for the current or
specified (Gross/Net/Tare) weight on the source scale. Possible
values are SPACE, NONE, + (for STR.POS#1), or – (for STR.NEG#1)
<U[P | S | T]> STR.PRI#1
STR.SEC#1
STR.TER#1 Units. Specifies primary, secondary, or tertiary units for the current or
specified weight on the source scale.
<M[G | N | T]> STR.GROSS#1
STR.NET#1
STR.TARE#1 Mode. Specifies gross, net, or tare weight for the current or
specified weight on the source scale.
<S> STR.MOTION#1
STR.RANGE#1
STR.OK#1
STR.INVALID#1 Status for the source scale. Default values and meanings for each
status:
STR.MOTION#1
M In motion
STR.RANGE#1 O Out of range
STR.OK#1 <space> OK
STR.ZERO#1 Z COZ
