Power Supply
The RCX C-Link at the camera end of a base-mode system has the following power requirements:
The 5 V power supply is small and comes with a U.S.-standard power plug.
The 12 V power supply includes four international power plug adaptors.
Power required on a full mode system has been measured at under 6 watts for each end — camera
and frame-grabber. This power is spread across two RCX C-Links: typically, two watts for the X
channel RCX C-Link, and 3.5 watts for the YZ channel RCX C-Link. A switching regulator inside the
RCX C-Link allows us to accept anything from 4.75–18 volts DC; however, lower voltages are
recommended to avoid running hot.
The two RCX C-Links at the camera end of a full-mode system can use either of the two power
supplies with the Switchcraft connectors. The two RCX C-Links at the frame-grabber end of a full-
mode system receive power from our resync cable through a female DB-9 connector. The resync
cable connects to the RCX C-Links through two Lemo 7-pin connectors.
Dimensions
The RCX C-Link box has the dimensions shown in

NOTE
With respect to the dimensions shown in
Figure 9:
Connector dimensions are approximate — refer to manufacturer’s specifications for precise
dimensions.
The power connector dimension of 0.31 inch is for the standard 2-conductor connector; the
optional Lemo connector is approximately 0.35 inch.
