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

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

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.
