Serial-to-Bluetooth Adapter

Introduction

This guide shows you how to set up your MultiConnect Adapter. For

detailed information, product specifications, and more, see the User

Guide, available on the MultiConnect CD and the Multi-Tech Web site.

General Safety

The modem is designed for and intended to be used in fixed and mobile

applications.

Caution: Maintain a separation distance of at least 20 cm (8 inches)

between the transmitter’s antenna and the body of the user or nearby

persons. The modem is not designed for, nor intended to be, used in

applications within 20 cm (8 inches) of the body of the user.

Radio Frequency Interference

Avoid possible radio frequency (RF) interference by carefully following

the safety guidelines below.

•Switch OFF the MultiModem when in an aircraft. The use of cellular

telephones in aircraft is illegal. It may endanger the operation of the

aircraft and/or disrupt the cellular network. Failure to observe this

instruction may lead to suspension or denial of cellular services to

the offender, legal action, or both.

•Switch OFF the MultiModem in the vicinity of gasoline or diesel-fuel

pumps or before filling a vehicle with fuel.

•Switch OFF the MultiModem in hospitals and any other place where

medical equipment may be in use.

•Respect restrictions on the use of radio equipment in fuel depots,

chemical plants, or in areas of blasting operations.

•There may be a hazard associated with the operation of your

MultiModem in the vicinity of inadequately protected personal

medical devices such as hearing aids and pacemakers. Consult the

manufacturers of the medical device to determine if it is adequately

protected.

•Operation of the MultiModem in the vicinity of other electronic

equipment may cause interference if the equipment is inadequately

protected. Observe any warning signs and manufacturers’

recommendations.

Multi-Tech Systems, Inc. Quick Start Guide

Vehicle Safety

•Do not use your Wireless MultiModem while driving, unless

equipped with a correctly installed vehicle kit allowing ‘Hands-Free’

Operation.

•Respect national regulations on the use of cellular telephones in

vehicles. Road safety always comes first.

•If incorrectly installed in a vehicle, the operation of wireless

MultiModem telephone could interfere with the correct functioning

of vehicle electronics. To avoid such problems, be sure that

qualified personnel have performed the installation. Verification of

the protection of vehicle electronics should be part of the

installation.

•The use of an alert device to operate a vehicle’s lights or horn on

public roads is not permitted.

Serial-to-Bluetooth Adapter

Installation and Cabling

Attaching the MultiConnect Adapter to a Fixed Location

1. Typically, the MultiConnect is mounted against a flat

surface with two mounting screws. Drill the mounting

holes at the desired mounting location. The mounting

holes must be separated by 4-15/16 inches center-to-

center.

2. To attach the mounting bracket, slide it into the

corresponding slot on the back of the MultiConnect

chassis.

3. Attach the adapter to the surface with two screws.

Multi-Tech Systems, Inc. Quick Start Guide

Making the Connections

Directions for the MTS2BTA (Externally Powered)

Turn off your PC. Place the adapter in a convenient location.

Connect it to your PC’s serial port and plug in the power.

Directions for the MTS2BTA-R (Powered through

Pin 6 of an RS-232 Cable)

Turn off your PC. Place the adapter in a convenient

location. Then connect it to your PC’s serial port.

The MTS2BT-R draws its power from Pin 6 of the

RS-232 cable.

Serial-to-Bluetooth Adapter

Optional – Directions for Direct DC Power

Connection for Use with the MTS2BTA

•Connect a fused DC power

cable into the power

connector on the

MultiModem.

•Then attach the two wires

at the other end of the

fused cable to a DC

fuse/terminal block on a

vehicle in which you are

mounting the MultiModem.

Connect the red wire to the

"+" positive and the black

wire to the "–" negative. Be

sure the GND connection is

correct.

Note: For automotive

application: according to the

type of application, you can

use permanent “+” or key-

switched “+”. Connect the

power supply to its source (for

example, in a mobile situation,

to the vehicle’s DC

fuse/terminal block).

Warning: Over-voltage

protection is provided on the

device. To ensure complete

protection, you may want to

add additional filtering to the

DC input.

Multi-Tech Systems, Inc. Quick Start Guide

Using AT Commands to Set Parameters

Parameters, such as the Bluetooth Name, Service Name, Device Class,

and Serial Port settings can be viewed and configured. This can be done

locally through the serial port UART or from a remote Bluetooth RF link.

To configure the Bluetooth adapter, it must be in command mode; issue

the +++ command to switch to command mode. While in command

mode, the adapter will accept ASCII bytes as commands.

The communications settings should match the settings used when the

Bluetooth adapter connects. For example, the defaults are:

9600bps, 8 bits, no parity, 1 stop bit, hardware flow control enabled.

Master Discovery/Connection Sequence Example:

From Power Up and No Connection

1. Verify Local Device is Master in Data Mode.

Sent: ATSi,7 <cr>

Reply: <cr_lf>1,1,0,0<cr_lf>

2. If not Master, Set to Master and Data Mode.

Sent: ATSW25,1,1,0,0 <cr>

Reply: <cr_lf>OK<cr_lf>

3. Perform Inquiry to Obtain BT_Addresses (when not known).

Sent: ATUCL // Clears radio state

Reply: <cr_lf>OK<cr_lf>

Sent: ATDI,1,00000000 {Class of Device}<cr>

// Looks for only one Bluetooth device

Reply: cr_lf>00A0961F2023,00000104,MTS2BTA

<cr_lf>DONE<cr_lf>CONNECT <cr_lf>

4. Perform a Master Connect over SPP Using the BT_Address.

Sent: ATDM, 00A0961F2023,1101<cr> // SPP connection

Reply: <cr_lf>CONNECT,00A0961F008F cr_lf> // Returns

Slave BT address; radio is in data mode

5. Place radio into Fast Data Mode.

Sent: +++<cr> // Places radio in Command Mode

Reply: <cr_lf>OK<cr_lf>

Sent: ATMF<cr> // Places radio in Fast Data Mode

Reply: <cr_lf>OK<cr_lf>

6. Send Data.

Note: Sending commands from the slave when the slave

connects in Fast Data Mode (ATSW25/ or issue ATMF):

All valid AT commands sent through the Slave's UART will be

interpreted and responded by the Master as if it were the local

Slave radio. Basically, in this configuration from the Slave end,

you can obtain status and configure the remote Master radio.

This is a unique feature that may be useful in some

applications, but it can be confusing if you think you are talking

to the Slave.

To Get Out of Data Mode and Check Status

1. Delay at least 50 milliseconds; this could be less or more.

2. Perform a Set Command Mode.

3. Delay at least 50 milliseconds.

4. Check Status, perform a Disconnect …

Note about being connected in Fast Data Mode

If connected in Fast Data Mode, it is necessary to reset the

Master or Slave to break the connection.

Multi-Tech Systems, Inc. Quick Start Guide

Slave Command Sequence Example

From Power Up:

1. Check and verify Communication to Slave.

Sent: AT<cr>

Reply: <cr_lf>OK<cr_lf>

2. Get information on Slave Bluetooth address.

Sent: ATSi,1<cr>

Reply: 12-digit address

<cr_lf>OK<cr_lf>

3. Set Slave to automatically connect in Fast Data Mode on

Bluetooth connection.

Sent: ATSW25,0,0,0,0 <cr>

Reply: <cr_lf>OK<cr_lf>

Either cycle power or send ATURST.

Note: This command sequence assumes the radio is set to

factory defaults that allow it to automatically come up and be

ready to connect as a Slave from a Master request.
