Local/Remote Operation

9.4

Local/Remote Operation

For systems that require two locations, 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, set STREAM to local or remote. Once the local unit scale has been
configured, use the SERIAL menu, serial commands or

Revolution

to set the serial parameters for local/remote

operation. See Table 3-3 on page 26 for comport options.

Printing operation can be performed at the remote unit and/or at the local unit. When the operator presses the

key at the local unit, a printing ticket will be issued only locally. When the operator presses the

key at the

remote unit, print will only occur at the remote unit.

Audit Trail Support

Audit trail support provides tracking information for configuration and calibration events. To prevent potential
misuse, all configuration and calibration changes are counted as change events.

Audit trail information can be printed from

Revolution

or by sending the DUMPAUDIT serial command. See

Figure 3-1 on page 22.

Revolution

can be used to display audit trail information. The audit trail display includes the

legally relevant (LR) version number (firmware version for the code that provides audit trail information), a
calibration count and, if REGULA=NTEP or Canada, a configuration count. The exact format of the information
shown depends on the regulatory agency specified for the REGULA (PROGRM menu) parameter.

See Section 1.8.10 on page 7 for steps to view the Audit Trail.

For NTEP and Measurement Canada modes

, there are two numbers displayed: configuration and calibration. The

configuration number tracks changes to the legally relevant configuration parameter changes. The calibration
number tracks changes to the scale calibration.

In OIML mode

, the only number displayed is audit trail. The audit trail number is incremental for any legally

relevant configuration parameter changes and all calibration changes. The last date the scale was calibrated is also
displayed.

9.6

Sleep Mode

Firmware version 1.03 and newer of the 480 features a sleep mode. It is designed to place the indicators into a low
power mode to reduce power consumption.

The sleep mode will only activate if the indicator is operating on its internal optional battery. If connected to
external AC power, the indicator will not go into sleep mode regardless of the parameter settings.

The indicator will enter the sleep mode, after the time specified in the

SLEEP

parameter, when no keypad activity is

detected and the displayed weight is below the weight threshold (

WGTHRH

). Setting the sleep parameter to never

disables the sleep mode.

Standby

While in sleep mode, at a time specified in the standby (

STDBY

) parameter, the indicator wakes up for about 0.5

seconds. The range of the standby time is 1 to 60 seconds. During the awake time, it checks for a change in weight
greater than the display division threshold (DDTHRH), or if the weight has gone above the weight threshold
(WGTHRH). It also checks to see if a key is being pressed and performs zero tracking.
