5.8. Resetting ADAPTER

The ADAPTER has a “reset button” located on the side of the case as shown in section 3.1 ADAPTER above. This button

performs 2 different functions.

a) Resets Paired Devices.

A short press (less than 3 seconds) of the reset button causes any paired device information to be deleted. When

the device is in low security mode, this will not have any effect on the devices operation, but while in high security

mode, this will mean that another device can pair with ADAPTER, or that the original device must expire its bond in

order to reconnect.

b) Resets ADAPTER to factory defaults.

A long press (more than 3 seconds) of the reset button causes all factory defaults to be restored. Care should be

taken here to remember that these “factory” settings can actually be updated via the interactive menu and thus may

not be the same as the device was shipped with. The user should also remember that ADAPTER is likely to need

it’s parameters re-configuring to ensure communications can be re-established with either the local serial device, or

remote Bluetooth device.

6. Physically connecting to your RS232 device

6.1. Configuring the communications parameters

The adapters do not have the ability to auto-detect the communications parameters (e.g. baud rate) so they must be

configured to match the data rate used in the application to which they are connected.

Please refer to section 5.3 Communications Parameters above, for details on how to do this.

It is possible, if a little confusing, to “pair” two adapters and have them physically connected to RS232 devices which use

totally different communications parameters.

6.2. Physically connecting your device to ADAPTER via the RS232 cable

ADAPTERS are supplied with either a 9-pin male (DTE) or a 9-pin female (DCE) ‘D’ type connector. The DTE (Data

Terminal Equipment) configuration has been chosen to allow for easy connection to DCE (Data Communication Equipment)

e.g. serial printers, medical sensors etc. RS232 devices that would normally connect directly to the RS232 port on a computer,

choose the (DCE) version. When connecting a DTE adapter to a computer you will need an appropriately wired gender changer

and null-modem adapter that allows the adapter to behave as a DCE device.

Connector Pin-Outs for the integral DTE cable (Male 9 Pin D Type) are…

1 N/C 4 DTR - N/C 7 RTS

2 RxD 5 Ground 8 CTS

3 TxD 6 DSR - N/C 9

As the RS232 standard allows for many different cable configurations, your device may need additional cable work with

the adapter, such as a cross-over or null-modem cable. Please refer to your devices documentation for specific details.
