VisionLink RCX Power Supply
EDT, Inc. 2016 August 30 15
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 4.75 to 28 V DC.
Table 8 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.
Power Supply
Each extender has an internal switching regulator that supports voltages of 4.75 to 28 V DC. For pin information and
polarity on the standard Switchcraft and optional Lemo power connector, see
Power Connector on page 13 .
Table 9 shows the base-mode power supply requirements.
