Digital interface for PLB-21
(RS-232)
LD +
(Anode)
LD –
(Cathode)
LD anode and cathode must be floated and must have no contact to GND!
The drawing shows all connections which are available to the user.
LDP-C BOB
Connector
See section “Interface Specifications” for detailed information. (Breakout
board connector.)
PLB
Connector for PLB-21 human interface device (protected against polarity
reversal).
Vin
Supply voltage must be about 4 V above laser diode compliance voltage but
at least +12 V. Do not exceed the limits listed in the datasheets. (24 V and
48 V respectively).
GND
Supply ground
LD+
Positive laser diode output (anode). It is highly recommended to use both
connectors parallel, especially for high currents.
LD-
Negative laser diode output (cathode). Do not connect to ground. It is highly
