The RF module is a radio transmitter/receiver that, on command from an Amtech
reader, generates a radio frequency (RF) signal in the location and monitoring service
(LMS) radio frequency sub—bands (902-904 and 90975-92175 MHz) and delivers the
signal to the antenna for broadcast The RF module also receives and demodulates the
reflected mg signal remmed dtrough the antenna, then preamplifies and conditions the
demodulated signal before sending it to the reader. The RF module generates the RF
power necessary to read an Amtech tag. It also contains receiver and preamplifier
circuitry to preprocess the mg signal returned through the antenna. Once connected to
the antenna and reader, the RF module should require no additional mechanical
adjustment by the user.
”261 1 HF Mada/a User Guide

Features
The RF module receives DC power through an internal power supply that is connected
to an external AC voltage source. A separate reader-to-RF module cable carries the
demodulated tag signals from the RF module to the readerand the control signals
from the reader to the RF module. -
Note: 11mg coaxial cable runs between the RF module and antenna can degrade
system performance and shouki be avoided in system configuration
RF output power is on whenever the reader activates the RF module. RF output power
may be turned off through reader firmware commands
Increasing or decreasing the RF signal strength directly impacts the system’s reading
range. To confine the reading range to its optimal ates, you can connect internal
attenuators that decrease the RF signal to the RF module.
Caution
Do not attempt to increase the RF signal strength. Contact Amtsch if you think any
adjustments to the RF signal strength are necessary.
For ease of installation the RF module is connected to the readm' by a cable attached to
a removable Zfi-pin circular connector.
See Appendix B of this User’s Guide for a listing of RF module specifications.

Introduction
Installing the RF Module 2
This Chapter describes the installation procedures for the RF2611,
including information on equipment, positioning, terminal connections,
and grounding.
The RF module has dual-antenna ports for transmitting and receiving signals. An
additional antenna port is provided for the internal system check tag, In nomml mode,
an RF module is connected to the reader through its 26-pin circular connector.
The following figure depicts the system configumtion for normal mode.

You need the following supplies and equipment to install the RF module.
Equipment

' 50 ohm load (placed at the antenna port for testing)
' ' Conununications soflware
Positioning
In permanent installations, the RF module should be positioned as close as possible to
the antenna and within 500 ft. of the reader. Long cable runs will increase system
sensitivity to noise. Coaxial cable runs in excess of 25 fl. between the RF module and
antenna are not recommended.‘ Longer cable connections (up to 1,000 cable 11.)
should be made on the reader-to—RF module links

Firmware Commands
Firmware Commands J
This chapter provides the commands needed to control and monitor the
status of the RF module.
Command Messages
The RF module firmware allows the user to control and learn the status of the RF
module through commands. A command message contains a two-byte ASCH code,
referred to as the command code, which uniquely identifies the command. Optional
ASCII data and an ASCII carriage return as an end-of-message indicator follow the
command code. The command message format that follows specifies the components
of a valid command message with < > indicating a mandatory component and []
indicating an optional component.
[cormnund—data]
The following example illustrates the components of a command message that sets the
uplink power on. The hexadecimal representation of the ASCII command message is
shown such that all bytes are illustrated.
Example Command Message: 3030310Dh
Command Response Messages
The RF module firmware implements command responses that are sent to the ISA
reader in response to acommand. All command responses contain a one-byte ASCII
code that specifies the response stains. followed by optional ASCII data, and an
ASCH carriage return as the end-of-message indicator. The command response
message format that follows specifies the items of a valid command response with < >
indicating a mandatory item and [1 indicating an optional item.
