MSI-9300 Porta-Weigh+ Crane Scale
SECTION 4 – RF REMOTE CONTROL
DESCRIPTION
MSI-9300 Series crane scales can be equipped with an RF Remote Control (RFRC). This differs from using
the MSI-9750A or MSI-3750CS Indicators to control the scale. The RFRC is a transmit only device that can be
used to perform basic scale functions. It does not have the range of the Spread Spectrum modems built into the
RF versions of MSI-9300 Series crane scales and is intended for local control only. Range will vary from 25’ to
100’ depending on room conditions and line of sight to the display. The remote receiving antenna is behind the
red lens of the crane scale and best range will occur when the display is visible to the operator using the RFRC.
One big advantage the RFRC provides is the ability to turn the unit on remotely. The RFRC can also be used in
systems that do not have the RF Modem.
The RFRC is available in three versions differing only in transmit frequency. The standard version operates at
418MHz. Available alternative frequencies are 315MHz and 433MHz.

FUNCTIONS
The RF Remote control duplicates the functions of the front panel keys on
MSI-9300 Series crane scales. The POWER, ZERO, NET/GROSS, and TARE
key function identically. In addition, the RFRC adds direct control of TOTAL
and VIEW TOTAL without the use of the USER key. The TOTAL still needs to
be enabled and configured in the embedded CellScale before these features will
function properly. See page 14 for the procedure to set up the Total mode.
The F1 key functions the same as the TEST/USER key on the front panel. The
exact function of this key depends on the USER key setup procedure. See page
12 for the procedure to configure the USER key which will also configure the
F1 key on the remote. Since the RFRC has a dedicated key for Total, there is no
need to program the USER key to Total, and it can be used for other purposes.
The F2 key is programmed to trigger a remote print. When F2 is pressed, the
crane scale will transmit the data string programmed in the virtual Comm Port
3 of the embedded CellScale. This data string can be used in a variety of ways.
For example, a remote printer can be connected to the MSI-9020 CellModem.
When F2 is pressed, the remote printer could print the weight along with time,
date, total weight, or any other data parameter available from the embedded
CellScale. Another common use is to send the weight data to a computer config-
ured to data log the information to a database.
For information on Data Strings and the use of Virtual CommPort 3, refer to the
MSI-9000 CellScale Users Guide. F3 and F4 are not supported by MSI-9300
Series crane scales. These keys function as TOTAL and VIEW TOTAL (∑).
SETTING THE TRANSMITTER ADDRESS
In order to allow the formation of up to 1024 unique
Transmitter-Receiver relationships, the transmitter’s
address may be selected using internal DIP switches as
shown. The switches are accessed by removing the DIP-
switch access cover.
If the switch is on, the address line is connected to ground, otherwise it is float-
ing. The receiver’s address must match in order for the units to communicate.
MSI supplies the transmitter and receiver as a matched
set with the DIP switches already configured. A replace-
ment RFRC will only need to have the transmitter DIP
switch set. To change the DIP switch in the receiver
requires disassembly of the crane scale front casting.
Due to differing DIP switch styles, the receiver DIP switch appears opposite to that
of the transmitter. On the receiver, the OFF position is on the right, and the ON
position is on the left.
