On-board regulator (L4931) can supply up to 250mA current at 5V.
R9 (LK1) connects pin 9 (Ring Indicator) on the D type to the 5V, which enables any external host to be
powered from pin 9 (+5V DC) and pin 5 (GND). Certain CCD barcode scanner can make use of this
feature, eliminating the need for additional external power adaptor.
R8 connects STATUS (data ready, via an RS232 buffer) to DCD, DSR and CTS. Not linking this jumper
(LK2 at the back of the board) saves power.
The SIG LED is provided for visual indication of STATUS data ready. This LED would lit when a valid
data is present in the receive buffer.
