4. Indicator light and press button
Link light is applied in RS232 Adapter to indicate the working state and the cmd
data switch is used to change the working mode (data mode or command mode).
LINK lights: If LINK light twinkles one time every five seconds, links with other
Bluetooth equipment should be finished; if it twinkles one time or even faster every
two seconds, it renders no links have been established. When there is no established
link, through LINK lights flashing speed, we can determine whether the equipment
has memorized address or not, that is to say, we can determine weather it is adaptable
for other Bluetooth equipment or not, if it twinkles fast (2 twinkles per second), it has
memorized address; if it twinkle slowly (1 twinkle per second), it means no memory
about addresses exists. For the principal equipment, it is normal that 2 twinkles per
seconds while consulting, 4 fast twinkles per second while matching, single twinkle
per second while linking, one twinkle per 5 seconds after connecting.
The LINK light extinguish while the RS232 is in the state of parameter stetting.
Cmd Data Switch: while moving Cmd Data Switch to the Cmd side, RS232
adapter indicator light is extinguished, the RS232 adapter is working in the state of
parameters setting. RS232 adapter stops working in the parameters’ setting state, you
can install only RS232 adapter parameters at this time. While moving Cmd Data to
the Data side, RS232 adapter quits the state of parameters setting, and begins to work
(search, match, link, transfer data, etc.) this time, but you can not install parameters of
the RS232 adapter. If users need to install parameters, please move Cmd Data Switch
to the Cmd side, if not, please keep the Cmd Data Data Switch on the Data side.
Hereunder attached the chart about indicator lights and button:
