1IntroductionThe 3e-250 Bluetooth to RS-232 Cordless Adapter is a Plug and Play adapter that allows you to use your RS-232 (serial) port to communicate wirelessly between multiple pieces of equipment. In itself, the 3e-250 requires no installation of software or drivers on the host machine. It doesn't initiate communications, but simply acts as a substitute for a wired serial connection. As such, it allows direct commu-nication between equipment such as data recorders, computers, handheld devices, test electronics equipment, measurement devices and the like.It enables users to connect measurement devices wirelessly to a cen-tral analysis and recording area, eliminating the need to download infor-mation from an unconnected measurement device.The adapter incorporates a Bluetooth solution containing a BT 1.1 compliant transceiver operating in the 2.4 GHz range using frequency-hopping at 1600 times/sec among the available frequency ranges.The operating range of the 3e-250 is up to 30m or 100 feet. It provides link control functionality and supports operation within a Bluetooth piconet in a slave mode. It supports all Bluetooth data rates of up to 723 Kbits/sec.InstallationThe 3e-250 Cordless Adapter comes precongured with certain basic parameters. No setup is required unless you wish to change these presets.The pre-congured parameters are:• Device Name The default name is 3ETI Serial Device. This name will be pre-sented to other devices which are trying to connect to it. (You might want to change this name if you are going to use a number of these Adapters.)• RS-232 baud rate The default baud rate is 9600, 8-N-1. (You might need to change this default setup depending on the device that you will be attach-ing it to.)If any change to the conguration is required, or you plan to imple-
23e-250 Bluetooth to RS-232 Cordless Adapter3User's Guidement more than a direct RS-232 cable replacement function, you will need to install at least one remote Bluetooth master device on a PC. The Bluetooth master, such as the 3e-240 Bluetooth USB Dongle, in-stalls on a USB port on your laptop and comes with software that allows you to manage up to 7 slaves. Some examples of possible congurations are shown below.Initial SetupIf some setup is required or you want to ensure the Adapter is work-ing, move the power switch to the "on" position and attach the DB9 serial port to a serial port on your computer.To verify that the device is working, open a "Hyper Terminal" applica-tion on your computer. You will usually nd this application by following the path, Start àPrograms à Accessories à Communications.With your 3e-250 Adapter on and attached to your COM port, the Hyper Terminal window should prompt you to connect to, for instance, Com 2 (if that is where your device is plugged in) as shown in the follow-ing picture.DB9 connectorOff On
23e-250 Bluetooth to RS-232 Cordless Adapter3User's GuideThe New Connection wizard will ask you to name your session and give you a choice of icons to associate with it. You can call it anything that will readily identify it for you. We chose "port1."Click OK to begin the Hyper Terminal session.You will next see a "connect to" screen. Select the COM port to which the 3e-250 is connected and click OK.Set the "connect using" dropdown menu to the COM port you are us-ing on your computer. This is usually COM1 or COM2.Click OK to go to the COM2 Properties screen.
43e-250 Bluetooth to RS-232 Cordless Adapter5User's GuideInitially, set the properties to 9600 8-N-1 with ow control at Hard-ware. If you will be using the 3e-250 Adapter with test equipment and you know that it requires a different baud rate than 9600, you can change that later, using the Hyper Terminal session. Normally, the only things that you will need to change are the baud rate and the device name.Click OK to save your settings and select Properties from the File dropdown menu.In the Properties window, select the Settings tab. In the Backspace Key Sends section, select the "Ctrl+H, Space, Ctrl+H" radio button. And click on the ASCII Setup button.In the ASCII Setup window, make sure you check the selection for "Send line end with line feeds" and "Echo typed characters locally." Checking these options will provide feedback when you issue commands in hyperterminal. (This is very useful as a means of checking that your command has been accepted.Important Note: If you are working in Windows XP, and your hyper-terminal software will not access the Bluetooth device, you may have to set the MODE switches to the ON position for both DSR and CTS.
43e-250 Bluetooth to RS-232 Cordless Adapter5User's GuideThen click OK and OK to close the Properties menu and return to the main Hyper Terminal screen. In the Hyper Terminal window, you can now type the command help and when you press the Enter key on your computer, you will get a list of the commands available to the 3e-250 device in the Hyperterminal session.You may want to save the Hyperterminal setup on your desktop so that you can use it to set up a number of the Adapters.
63e-250 Bluetooth to RS-232 Cordless Adapter7User's GuideTo save it, go to FileàSave and save to the Desktop. You will see an icon similar to the following on your desktop.After a Hyper Terminal session, you may also see two other icons on your Desktop. These two les, which should look similar to the two shown to the right, can be dropped in the Recycle Bin.Operation and MaintenanceTransferring data from PC to PCThe 3e-250 Bluetooth to RS-232 Cordless Adapter can be used, with another Bluetooth device, installed on another computer, to transfer data between the two machines. The other Bluetooth adapter can be the 3e-240 Bluetooth Dongle or any Bluetooth-certied RS-232, USB, or PCMCIA product. Refer to the manual that came with the other Bluetooth device for instructions on its installation and operation.Once the other device is installed, let it discover all available devices.(NOTE: If there is more than one Bluetooth device for it to discover, you may want to use your Hyper Terminal session to rename your 3e-250 Adapter, using the devicename command. See the table of commands on page 9 for more information.)Select the 3e-250 Adapter from the list of discovered devices by its name and double-click it to initiate the process of connecting to the Adapter. The Adapter provides the service "serial port."Double-click on the "serial port" service icon and the local device will connect to the Adapter and set up the serial port service, using a lo-cal COM port for the connection. Make a note of the COM port number selected and open a Hyper Terminal session. Connect to the virtual COM port you have just set up, using the procedure detailed in the section Initial Setup. You can set the baud rate for this COM port to any value up to 115200.
63e-250 Bluetooth to RS-232 Cordless Adapter7User's GuideAt this point, you have completed the communication setup between the 3e-250 Adapter and the other Bluetooth device.To verify the connection, type some characters in the Hyper Terminal window on one of the computers. The same characters should be visible in the Hyper Terminal window on the other computer. Whole les can be transferred using the Transfer à Send File option in the Hyper Terminal window.Connecting to a Test InstrumentConnecting to a test instrument can be a bit more complex than con-necting from PC to PC, because you will need to know the RS-232 signals supported by the particular instrument. Each test instrument has its own mechanism which that instrument uses for hardware ow control (RTS/CTS and DTR/DSR). Before installing the 3e-250 Adapter on a test device, research the required settings for that test device in its documentation. The 3e-250 Adapter has two dipswitch settings accessible on the back (bottom) of the device.The dipswitches allow you to congure for the particular device. The DTR/DSR switch is set to the ON position by default. The RTS/CTS switch is set OFF by default.Once you have congured the dipswitches, connect the 3e-250 to the DB9 connector on the test instrument. If there is not enough space to directly connect to the DB9 connector, use a 9-pin straight cable with a male connector at one end and a female connector at the other. (This is not included in the install kit.)You can now communicate to the 3e-250 from the Bluetooth device on the host PC.Using the LEDsThere are three LEDs on the 3e-250. • Bluetooth Link Activity Indicator• Battery Status Indicator• Battery Charging Indicator

If the Battery Status Indicator turns red, you should recharge at your earli-est convenience. Plug in the 120V AC / 9V DC power adapter shipped with the 3e-250 and charge fully (may require up to 3 hours). Recharging should be done in conditions of less than 113 ° F (45 ° C) to ensure proper charge.There is an RS-232 Trickle-Charge on-off switch on the back of the 3e-250 which is provided as a discretionary battery power conserva-tion device. The default position is OFF. And this switch should be left in the off position if you are running the device connected to any piece of test equipment that runs on battery power, as it will "steal" the power from the parent device in order to "trickle-charge" the 3e-250 battery. However, if you are running the 3e-250 on a host device that can spare power, you can conserve battery power extensively by setting the RS-232 Trickle-power switch to on. When the 3e-250 is charging from an AC power outlet, the switch can be either on or off. It does not matter. See the picture of the back of the device on the preceding page for the location of the Trickle-Charge switch. Move the switch with a small point object like a paper clip or pen point.
