Cable Assembly – Lemo to Female DB9 RS232
The Lemo to female DB9 cable assembly (EDT part #016-12445) supports integrated CMOS +3.3 V to RS232 level
converters on a small circuit board inside the DB9 connector shell.
This cable is designed to plug in directly to a host computer serial port. The cable offers an auxiliary serial UART
connection over the fiber, in addition to the UART normally associated with the Camera Link standard. This auxiliary
UART can be used, for example, to control the camera’s pan and zoom servo motors from the host at 115.2 kb/s or less.
Alternatively, it can be used for other low bandwidth signals.
Unlike the DB9 in the male assembly, this DB9 does not supply power to the extender. Instead, a red wire (power) and
a black wire (ground), each 24 inches long, are left loose so you can hook up your own power source. The required
power is 12 V DC.
shows the pinout and how the standard firmware uses each wire. DB9 pins 1, 4, and 6 are wired together and
unconnected, 7 and 8 also are wired together, and 9 also is unconnected; these signals are not otherwise used.

All five CMOS 3.3 V
signals go to FPGA I/O
3.3V pins using series
100-ohm resistors.
Custom firmware can be
used to configure these
pins as input or output.
