ThingMagic Vega
Set Up Guide
ThingMagic Vega Set Up Guide 5
Introduction
The Vega Reader kit is a self-contained reader that can be deployed as a UHF RFID reader
with a standard serial interface. The Vega is built on the ThingMagic M5e module. For
more information on the M5e please see the M5e-Family Developer’s Guide.
This document provides an overview of the hardware and basic command and control of
the Vega. The ThingMagic Vega RFID Reader is compatible with ThingMagic’s
application development tools, including the cross-product MercuryAPI, permitting rapid
creation of solutions to support a wide range of applications.
The MercuryAPI supports Java, .NET and C programming environments. The
MercuryAPI Software Development Kit (SDK) contains sample applications and source
code to help developers get started demoing and developing functionality. For more
information on the MercuryAPI see the MercuryAPI Programmers Guide and the
MercuryAPI SDK, available on the ThingMagic website.
A demo application which supports reading and writing is provided in the MercuryAPI
SDK package. The source code for this example is included in the MercuryAPI SDK
package under /cs/samples/exe/Universal-Reader-Assistant.exe.
Introduction
See the Readme.txt in /cs/samples/Universal-Reader-Assistant/Universal-ReaderAssistant for usage details.
See the MercuryAPI Programming Guide for details on using the MercuryAPI.
Note
In some cases the configuration of the Vega differs from that specified for
the standalone Mercury5e module. These cases are noted in this document.
In-vehicle Reader Notes
The contents of the Vega Setup Guide apply to both the Vega RS (Ruggedized System)
and the Vega IVR (In-Vehicle Reader). The IVR variant has the following exceptions:

The ThingMagic Vega reader
One, Two or Three antennas and Cables, depending on your configuration
Documentation and software development kit packages can be found at
http://rfid.thingmagic.com/devkit
One Jumper Terminator for the ReaderEnable on the GPIO Connector. (Not included
with the IVR)
Note: If the ReaderEnable jumper is not connected another method must be used to “turn on”
the reader as described in ReaderEnable
Additional required equipment:
.
Straight-thru DB9 serial cable.
USB to Serial adapter (if the connected PC doesn’t have an RS232 COM port)
One DC power supply with power cord (Optional)
Note: This product is intended to be supplied by a Listed power supply marked ‘LPS’ or ‘NEC
Class 2’ and rated 8-16V, minimum 1A.
WARNING!
The Vega antenna ports may be susceptible to damage from Electrostatic
Discharge (ESD). Equipment failure can result if the antenna or communication
ports are subjected to ESD. Standard ESD precautions should be taken during
installation and operation to avoid static discharge when handling or making
connections to the Vega reader antenna or communication ports. Environmental
analysis should also be performed to ensure static is not building up on and
around the antennas, possibly causing discharges during oper ation. See the
M5e-Family Developer’s Guide | Appendix E or contact
support@thingmagic.com for more details on ESD.
ThingMagic Vega Set Up Guide 7
Setting up Vega
When setting up Vega, use the following procedures:
1. Connecting the Antenna(s)
2. Powering up the Vega
3. Connecting the Serial Cable
Connecting the Antenna(s)
ThingMagic supplies a variety of monostatic antenna types for use with Vega. Vega supports up
to three antennas. Use the following procedure to connect the antenna to the Vega.
WARNING!
Setting up Vega
To prevent damage to Vega, never apply RF power to an antenna port that
does not have an antenna or terminator connected to it.
1. If the antenna does not have an integrated cable, connect one end of the coax cable
to the antenna.
2. Connect the other end of the coax cable to Ant 1, Ant 2 or Ant 3 antenna port on the front of
the module.
Using Three Antennas
The antenna port configuration uses a combination of two configuration settings (antenna
port and GPO #1) for the three antennas:
Table 1: Antenna Configuration Settings
Antenna Port Setting GPO #1 Setting
Antenna 1 TX=2, RX=2 n/a
Antenna 2 TX=1, RX=1 High
Antenna 3 TX=1, RX=1 Low (default)
8 ThingMagic Vega Set Up Guide
Setting up Vega
Note
In order to use the Antenna 2 port it is necessary to set the antenna
configuration and toggle the GPIO Output #1 to High.
When using the MercuryAPI (v1.9 and later) to develop Vega applications the GPIO
mapping for antenna configuration is handled for you. You can simply specify antennas
as 1, 2 and 3 and they will map to the labels on the Vega. If using low level serial
commands the GPO configuration needs to be handled “manually” using the settings
described in the Using a Multiplexer section of the M5e-Family Developer’s Guide to
create the mappings in Antenna Configuration Settings
Powering up Vega
After connecting the antenna (s) and terminating any unused ports, you can power up Vega.
1. Connect the serial cable from a PC to Vega

Reading Tags
The Universal Reader Assistant senses the COM ports that are located on your
system.
When using an RS232 COM port it is typically statically assigned COM1.
If using a USB to Serial adapter, USB devices are typically assigned higer value COM
ports. If many COM ports are listed in the menu and you aren’t sure which is for the USB
Adapter you can find the assigned value using the Windows Device Manager:
a. Open the Device Manager (located in Control Pa nel | System)
b. Select the Hardware tab and click Device Manger"
c. Select View | Devices by Type | Port s (COM & LPT)
The device appears as USB Serial Port (COM#). The USB adapter COM port value
is in parentheses.
5. Follow the Readme.txt in /cs/samples/Universal-Reader-Assistant for steps to read
and write tags.

ThingMagic Vega Set Up Guide 11
Using GPIO and ReaderEnable
Note: Note that there is no GPO-1 connection. This signal is used for switching between
antennas 2 and 3.
Figure 1: Connector Cable
ReaderEnable
There are two connections that can be used to enable the reader. The Serial connector
provides access to the ReaderEnable1 signal. The GPIO connector provides access to
the ReaderEnable2 signal. At least one of these signals must be pulled to greater than
+2V for the reader to be active. These signals can be used to remotely turn the power off
for power savings. The ReaderEnable Jumper Terminator provided with your reader will
connect pins 4 and 5 of the GPIO connector providing +12VDC to the ReaderEnable2
input.

Figure 2: Vega Mechanical (all dimensions in cm)
Mounting the Reader
To mount the reader on a ceiling or wall, follow these steps:
1. Hold the reader in its mounting location and mark the position of the four mounting
screws.
ThingMagic Vega Set Up Guide 13
Mechanical
2. Drill holes for the screws and install wall or ceiling anchors if required. For ceiling
mount, use only anchors specifically designed for ceilings.
3. Hold reader over holes and insert the screws and tighten until almost flush with the
wall.
4. Tighten the screws.
Rack Mount Considerations
Elevated Operating Ambient
If installed in a closed or multi-unit rack assembly, the operating ambient temperature of
the rack environment may be greater than room ambient. Therefore, consideration should
be given to installing the equipment in an environment compatible with the maximum
Operating Temp
.
Reduced Air Flow
Installation of the equipment in a rack should be such that the amount of air flow required
for safe operation of the equipment is not compromised.
Mechanical Loading
Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
Circuit Overloading
Consideration should be given to the connection of the equipment to the supply circuit
and the effect that overloading of the circuits might have on overcurrent protection and
supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
Reliable Earthing
Reliable earthing of rack-mounted equipment should be maintained. Particular attention
should be given to supply connections other than direct connections to the branch circuit
(e.g. use of power strips).

frequency energy that could interfere with radio communications, a situation the user
would have to fix at their own expense.
This device has been designed to operate with the antennas provided with it (MTI MT-
262024) and having a maximum gain of 7dBic. Antennas not listed here or having a gain
greater than 7dBic are strictly prohibited for use with this device. The required antenna
impedance is 50 ohms.
To reduce radio interference to other users, the antenna type and its gain is chosen such
that the equivalent isotropically radiated power (EIRP) is not more than permitted for
successful communication.
EQUIPMENT MODIFICATION CAUTION
Equipment changes or modifications not expressly approved by ThingMagic, Inc., the
party responsible for FCC compliance, could void the user's authority to operate the
equipment and could create a hazardous condition.
IMPORTANT USER INFORMATION
In order to comply with FCC and IC requirements for RF exposure safety, a separation
distance of at least 20 cm (7.9 in) needs to be maintained between the radiating elements of
the antenna and the bodies of nearby persons.
