The remote display function allows a master unit (370 or 375) to be echoed to another unit (350
I.S., 355 I.S., 350, 355) and be used in a remote location. There are certain parameters that must
be set in order to have the master and slave units communicate together. Refer to the section
below to configure the master and remote (slave) units.
M ASTER T O R EMOTE (S LAVE ) C ONFIGURATION
The remote unit will receive continuous transmission from the master unit. It is necessary to setup
the protocol parameters in both units so they match in order to coordinate the transmission. See
Table 3-14 for the common protocol parameters. A remote unit will not show the bargraph even
if it is a LCD display.

To enter the master or remote setup (local setup)
It is possible to make changes to the master unit setup mode from either the remote unit or the
master unit itself. The master unit setup mode can be entered from either the master or the
remote units. However, the remote unit (slave) setup mode can ONLY be entered from the
remote unit. After in the setup mode, you can make changes from the remote unit or the master
unit.
To enter the master unit or remote unit (local unit) setup mode (370, 350, 350 I.S. or 355 I.S., 375):
[ZERO] + [SELECT]
[SELECT], [ZERO], [PRINT], [UNITS], [TARE]
or
23640 [SAMPLE/Enter] (Model 355 or 375)
After the setup mode is entered, the numeric portion on the 375 keypad is restored. When in the
remote (slave) setup, all annunciators are illuminated on the remote to distingush between the
master and remote (slave) units.
S ETUP M ASTER U NIT
Set the following parameters on the master unit:
• P290 - Choose the communication port of the master unit the remote unit is connected to.
• P291 - Transmit any ASCII character or control code to the remote unit as a start
character before echoing unit's display. Make sure this parameter matches P274 on the
remote unit.
• P292 - Transmit any ASCII character or control code to the remote unit as an ending
character after echoing unit's display. Make sure this parameter matches P275 on the
remote unit.
• P296 - Choose the remote unit type, a 300 series or 60 series.
