Introduction
1.0 Introduction
The SENDit Wireless Load Cell Interface transmitters and receivers are efficient communication devices that replace the need
for traditional wire runs. Compatible with a broad range of transmitting and receiving devices, SENDit is designed to work with
ScaleCore-based products as shown in Figure 1-1 on page 3. SENDit transmitters can interface with virtually any strain-gage
sensor. This manual provides the details for SENDit and SENDit installation, configuration and calibration.
Manuals and additional resources are available from the Rice Lake Weighing Systems website at www.ricelake.com

Introduction
1.3 Overview
The SENDit offers an effective wireless load cell cable replacement in systems where it would be difficult to have a load cell
cable. Replacing the cable with an RF link, the output is then set to match the device that the cable was connected to.

2.0 Installation
This section describes procedures for connecting load cell, power, and serial communications cables to the SENDit.
2.1 Unpacking and Assembly
SENDit transmitter and receiver units are factory paired. Take care when unpacking orders of multiple units to keep the paired
sets together. In the event a transmitter or receiver must be replaced or the units must be re-paired, see Figure 2-3 on page 6
for paring information.
Immediately after unpacking, visually inspect the contents to ensure all components are included (refer to the packing list) and
undamaged.
If any parts were damaged in shipment, notify Rice Lake Weighing Systems, and the shipper immediately.
2.2 Mounting the Enclosure
The SENDit can be mounted either vertically or horizontally to a flat surface.
If mounted inside an enclosure or I-beam, use the correct antenna for the environment and distance. Please call Rice Lake
Weighing Systems if assistance is needed to select an antenna, or reference the antenna selection guide in the appendix.
Antennas must be placed in appropriate line-of-sight for reliable communications.
Ensure antennas are securely connected to both the transmitter and receiver.
A standard antenna and coax connector are resistant to water, but not waterproof.
Seal the TNC base with an adhesive heat shrink boot if antenna is exposed to water.

2.3 Cable Connections
2.3.1 Connect Transmitter
Using the optional pre-wired cable (Table 2-1) or the field wire-able connector (Figure 2-2), connect a SENDit transmitter to the
load cell or j-box; eliminating the need for a homerun cable.
See Section 4.0 on page 9 for calibration procedure.

Figure 2-2. Field Wire-able Connection
2.3.2 Connect Receiver
1. Connect the power source (Table 2-2) to the transmitter.
2. Using a 9 pin serial cable, connect the transmitter to a computer. This allows setup with the MSI TranSend mV/SENDit
Receiver Calibration program. See Section 4.0 on page 9.
