Accessory Board Configuration

Introduction

This document describes the ThingMagic M5e Module Accessory hardware and how to

configure them for use with the M5e Embedded Module. These accessories are primarily

designed for use with the M5e Module but can also be used with the M5e-Compact

(except the heatsink) with minor modifications to the instructions.

These accessories allow developers to quickly create prototypes and products to meet a

wide variety of applications.

 The 4 Port Multiplexer Board allows one M5e module to support up to 8 ports (using

two multiplexers); compatible with M5e antenna detection and search algorithms.

 The Power/Interface Board converts the M5e serial interface to high speed USB and

conditions incoming DC power to support in-vehicle or AC powered applications.

 The M5e heatsink allows use of the M5e module in environments where continuous

reading or high ambient temperatures are required.

 The optional hardware Accessory Parts Kit contains sufﬁcient interconnect cables and

mounting/spacing hardware to create an 8-port reader “stack”.

4 Port Multiplexer Board

The multiplexer board contains the following important I/O and control components:

Multiplexer Components

The physical antenna port in use, labeled J1 through J4 on the board, is controlled by the

MUX1 and MUX2 input lines on the input terminal connector. The control map is as

follows:

Accessory Board Configuration 5

Antenna Port Control Lines

Note

Interpreting the control lines as binary “numbers” gives an incorrect order

relative to the physical order of the ports. A key printed on the board serves

as a reminder that, from left to right when looking down at the board, the port

order is J1 – J2 – J4 – J3.

These lines can be controlled directly by an external controller/motherboard providing

TTL signals or by using signals from the M5e.

External MUX Control (Block 23)

When controlling the Multiplexer using external TTL signals the terminal pins on the board

serve as input signals as defined in Antenna Port Control Lines table. In this configuration

the M5e software has no knowledge of which multiplexed line is in use. All antenna ports

on a Multiplexer will look like Antenna 1 or 2 (depending on which M5e port is used) and

the associated Antenna ID metadata will be the same for all four ports. It is the users

responsibility to manage coordination between the MUX control line settings and the M5e

RF operations and tag response data.

For this configuration no jumpers should be present on terminal block 23.

M5e Control (Block 23)

The Multiplexer can be controlled using the M5e GPOutput lines by connecting the ribbon

cable between the M5e and the Multiplexer board and adding jumpers on the terminal

pins, connecting MUX2 with OUT2 and MUX1 with OUT1.

This method allows the M5e to use its built-in support for (up to 8) multiplexed antennas.

This enables automatic control of GPO to MUX signals to switch ports based on the M5e

logical antenna setting and association of tag read information with the corresponding

antenna ID meta data.

When using the M5e built-in multiplexer support the ports are also identified by pre-

defined logical port numbers - this requires M5e firmware version 1.3.0 or later. In a

stacked configuration, multiplexers are installed upside-down relative to the M5e board.

Assuming that the multiplexer closest to the M5e is connected to M5e port 1 and the one

farthest is connected to M5e port 2, the logical port numbers would be as shown here:

4 Port Multiplexer Board

Accessory Board Configuration 7

Logical Port Configuration

The reason for numbering the logical ports in this way was so that “logical port 1” would

stay associated with physical port 1 on the module whether there was a multiplexer

connected to it or not and, similarly, “logical port 2” would stay associated with physical

port 2 whether there was a multiplexer connected to it or not. If the application calls for a

mixture of manual control of the multiplexer (via physical port selection and GPIO Output

line manipulation) and automatic control (by configuring a search list of logical antennas),

the benefits of this numbering system will be more clear.

The resulting full control map with physical and logical port numbering is:

Terminal Block 23 Pins

The following Block 23 Pin Function Summary table contains a detailed list of the terminal

block 23 pins and their function based on the overall board configuration, whether the

multiplexer to M5e ribbon cable is connected and whether the jumper blocks are

connecting the multiplexer to a controller motherboard. A printed key on the multiplexer

board below the terminal pins also indicates which jumper pins are connected to which

internal function.

Antenna Detection

When using the multiplexer in the M5e Control (Block 23) configuration the M5e

functionality for manually (Get Antenna Configuration - 61h command) and automatically

(Set Reader Configuration - 9Bh, option 0x04 - Check Antenna Connection) detecting

connected antennas can be used.

This functionality requires the M5e module to be running firmware v1.3.0 or later.

Note

Reliable antenna detection requires that an attached antenna pass at least a

small amount of DC current. Many antennas do not pass DC current. Due to

such antennas an indication that a port is connected/terminated is always

accurate, but an indication that a port is not connected/terminated may not

be accurate.

trolled by module.
