2.2. Comparison of BL-819 and BL-830 Features
The BL-819 and BL-830 adapters share almost identical features, with the only difference being the gender
of the adapter. The BL-819 is 9-pin male (DTE) with the BL-830 being female (DCE).
The main anticipated use of BL-819 is to be connected to a DCE device that would normally plug into the
back of a PC. If you wish to use BL-819 as a DCE device (e.g. to plug into the back of a PC or similar for
configuration) you should use the included “gender changer”.
The BL-830 is supplied with a DCE connector (female) and no gender changer is supplied. This device will
plug into any serial port on a PC or Laptop.
2.3. BL- 819 / 830 Power Options
The BL-819 & BL-830 also carry the ability to be powered through Pin 9 by a suitable serial port. This
negates the need for an external power source. Brainboxes offer two serial cards, which can perform this function
for the BL-830, UP-189 and UP-200. NB. The BL-819 can be powered through Pin 9, but not with the supplied
gender changer. For information of the power requirements of your RS-232 Bluetooth Adapter, please see the
Input Voltage Requirements in the Technical Specification Section.
