RN-BT-SRL-UM Bluetooth Serial Adapter © 2011 Roving Networks. All rights reserved. USER MANUAL RN-BT-SRL-UM-1.0 Version 1.0 11/11/2011... - Page 2 OVERVIEW Roving Networks offers a variety of Bluetooth serial adapters with different form factors and powering options (see Table 1). These adapters enable wireless connection to any legacy serial port and support bi-directional RS-232 or RS-422 signaling at a rate of up to 464 Kbps. To create a wireless cable replacement solution, simply attach the adapter to your device's RS-232 or EIA-232/422 port and connect to it over Bluetooth.

Refer to the Bluetooth Advanced User Manual on the Support page of the Roving Networks website at http://www.rovingnetworks.com/Support_Overview for more information on using sniff mode.

RN -BT -SR L-U M- 1.0 Reducing Power when Disconnected Low-power connection mode disables the Bluetooth radio and LED timers when the adapter is disconnected. In low-power mode, the adapter cycles between active (discoverable and connectable) and low power deep sleep. This mode saves considerable power when the module is waiting for long periods of time without a connection. -
Page 5: Configuration Switches
In slave mode, this switch sets a special class of device that is used by the master to auto connect. If switch 3 also turned on, the adapter performs a search, stores, and connects to a remote Roving Networks Bluetooth device that has switch 2 turned on. Automatic master With this switch turned on, the adapter acts as Bluetooth master and auto-connects to a stored remote address. - Page 6 There are two ways to configure the Bluetooth module: • Local configuration using your computer’s serial port Via Bluetooth • You need a terminal emulator to complete the setup. NOTE: Roving Networks suggests using either the TeraTerm (Windows OS) or CoolTerm (Mac OS-X) terminal emulator program. www.rovingnetworks.com...
- Page 7 RN -BT -SR L-U M- 1.0 Local Configuration Using a Serial Port Connect the Bluetooth adapter to your computer’s serial port. (The RN-240M may require a null-modem cable, i.e., with DB9 pins 2 and 3 swapped; the RN-240F requires a straight cable). If your computer does not have a serial port, you can use a USB-to-serial cable such as the RN-USB-SERIAL to connect the Bluetooth adapter to your computer.

Page 9: Making A Bluetooth Connection
RN -BT -SR L-U M- 1.0 MAKING A BLUETOOTH CONNECTION By default, the Bluetooth adapter acts as a slave and the PC is the master. You connect to the Bluetooth adapter using your computer’s Bluetooth device manager, which varies depending on the operating system. Regardless of the operating system, the process is the same: discovery, pairing, and connecting. - Page 10 The pin code is a series of numbers or characters. NOTE: The default pin code for Roving Networks Bluetooth adapters and modules is 1234. After you enter the pin code, the Bluetooth devices compare them. If they match, a link key is generated and stored.

Page 12: Appendix A - Null Modem & Flow Control Jumpers
You can configure the adapter’s serial interface to enable flow control and null modem signaling. You access the jumper block by removing the cover from the Bluetooth serial adapter. Figures 10 and 11 show the jumper settings. WARNING: Flow control signals are NOT RS-232 signaling tolerant. If you enable these signals with the jumpers, do not exceed 3.3-V DC or permanent damage can occur. - Page 13 RN -BT -SR L-U M- 1.0 Figure 9.
