VisionLink RCX Pin Assignments
EDT, Inc. 2016 August 30 14
Cable assembly – Lemo to loose wire
The Lemo to loose wire cable assembly (EDT part #016-02650) can be wired as needed or connected to various types
of connectors, depending on your application.
Cable assembly – Lemo to male DB9
The Lemo to male DB9 cable assembly (EDT part #016-02718) supports signals that can be used as an auxiliary
signaling system for a variety of purposes.
For example, with custom firmware you could control the camera’s pan and servo motors, or set up a hardware trigger
that is local to either end. If you wish to explore these options, contact EDT.
Unlike the DB9 in the female assembly, this DB9 has no looped-back signals or integrated level conversion.
Table 7 shows the pin assignments and how the standard firmware uses each wire.
Cable assembly – Lemo to female DB9 RS232
The Lemo to female DB9 cable assembly (EDT part #016-02445) 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 19.2 Kb/s or less.
Alternatively, it can be used for other low bandwidth signals.
Table 6. Pin assignments – Lemo to loose wire
Lemo pin Wire color Standard firmware Signal level Comments
1 (output) green AUX_TX, primary auxiliary transmit UART CMOS +3.3 V
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.
2 red power to extender +4.75 to +28 V
3 (output) orange AUX2_TX, secondary auxiliary transmit CMOS +3.3 V
4 (input) brown AUX2_RX, secondary auxiliary receive CMOS +3.3 V
5 white SYNC, can be configured as an outgoing copy of
the camera’s frame-valid signal CMOS +3.3 V
6 (input) blue AUX_RX, primary auxiliary receive UART CMOS +3.3 V
7 black ground ground
