EE1941XS/EN1941XS One-Way Serial RF
Module
Installation and Operation Manual - 06288D
1 Overview
EchoStream RF modules are designed to be easily interfaced with your electronic
remote application controller (RAC). Your RAC contains application specific
functionality and uses the RF module to send application-specific data over the
wireless network. The RF module communicates with your application controller via a
wireless connection, and your remote application controller via a serial connection,
allowing the assimilation of any user-specific application into an EchoStream system.
Once integrated with an existing product, an RF module provides you with complete
EchoStream functionality.
The E*1941XS, equipped with the UART logic-level serial connection, is primarily
intended for use as a daughter board, interfacing directly with your RAC.

The E*1941XS is a one-way serial data transmitter, designed to physically interface
with your product. Serial data sent to the E*1941XS from your remote application
controller is formatted by the E*1941XS, and the data is then transmitted as an RF
message to the network coordinator.
There are two models in the E*1941XS product family.
• The EN1941XS, for 900 MHz applications in North America, New Zealand, and
Australia
• The EE1941XS, for 868 MHz applications in Europe

Frequency band selection pins (EN1941XS only) Place a jumper to select the
frequency band for your geographic area.
• Place the jumper on the left two pins to select 915-928 MHz for Australia.
• Place the jumper on the right two pins to select 921-928 MHz for New Zealand.
• Leave the jumper off the pins to select 902-928 MHz for North America.
ES selection pins (EE1941XS only) To enable compatibility with ES products, place
a selection jumper on the ES selection pins; if no ES products are used in your
system, remove the selection jumper.
Secondary alarm Driving pin high triggers a secondary serial alarm status message.
Primary alarm Driving pin high triggers a primary serial alarm status message.
Tamper input Driving pin high triggers a serial tamper status message from the RF
module to the RAC. Does not trigger an RF tamper message.
Reset input Connects a reset input, to reset the one-way serial data RF module after
a frequency band selection change.
Power Connect power cabling to an external power supply of 2.4 to 5.5 volts.
Ground Connects to ground.
Mounting hole Used to mount the one-way serial data RF module to the user-specific
product. The mounting hole should only be used with a nylon standoff, never metal.
Board stabilization holes Used to mount and stabilize the board. The board
stabilization holes should only be used with non-metal standoffs.
Data output Outputs messages to the RAC.
Data input Receives messages from the RAC.
