     1= CO-RJ45-PWR In-line CANOpen Adapter = 
     3== Introduction == 
     4'''Purpose:''' an in-line board for RJ45 CANOpen networks that provides: 
     5 1. Access to all CANOpen signals for testing 
     6 1. Provide power to CAN_V+ line 
     8Files are [ here for subversion (Eagle PCB files)] and [ here for WordPress (Eagle PCB files)] 
     10== Board Features == 
     11 1. Designed to be used in-line with in and out RJ45 jacks. 
     12 1. Provides a pin header for a removable terminal block. 
     13   1. All the RJ45 CAN signals are clearly labelled. 
     14   1. The Phoenix pin-style header provides an easy connection for grabber-type oscilloscope probes. 
     15   1. But you can also use the terminal block if that's easier. 
     16   1. '''NOTE: the terminal block header is not polarized''', so be careful not to plug the terminal block plug in backwards. 
     17 1. Provides easy and flexible power to CAN_V+, in case your equipment needs it (most CAN interfaces do not provide power, or make it easy to provide power, to CAN_V+). 
     18 1. Can be DIN-rail mounted. 
     20== Design Notes == 
     21The various signal lines are connected as follows: 
     22 * All signal '''except CAN_V+''' are connected to J1 (CANOpen In RJ45), P1 (8-pin header) and J2 (CANOpen Out RJ45) 
     23 * CAN_V+ can be connected from J1 to J2 by inserting both jumpers on JP1 
     24 * J1 CAN_V+ is always connected to P1 CAN_V+ 
     25 * TB1 CAN_V+ can be connected to J1 CAN_V+ and J2 CAN_V+ by using jumpers.  
     27== Normal Use == 
     28 * Connect the incoming CANOpen RJ45 cable to J1.  Connect the outgoing CANOpen RJ45 cable to J2. 
     29 * Make any desired monitoring connections using P1 (with or without terminal block). 
     30 * If the CANOpen devices needs power on CAN_V+, you have several options: 
     31   * Connect CAN_V+ power from TB1 to all devices connected to J1: only J1 (In) JP1 jumper is installed. 
     32   * Connect CAN_V+ power from TB1 to all devices connected to J2: only J2 (Out) JP1 jumper is installed 
     33   * Connect CAN_V+ power from TB1 to entire RJ45 network: both JP1 jumpers are installed 
     34   * Break the link between CAN_V+ on J1 and J2: both jumpers are removed from JP1 
     35 * So JP1 provides a lot of flexibility in providing multiple CAN_V+ voltages to your network -- but, as always, be careful, since you don't want to provide, say, +24VDC CAN_V+ to a device designed for +12VDC.

     54 * Get the PCB made at your favorite PCB fab.  Some will take Eagle files; almost all take Gerbers.  I do not provide Gerbers because different PCB makers have different standards. 
     55 * If you do not need to provide external CAN_V+, you can skip JP1,TB1, the 2-pos terminal block plug, and the jumpers. 
     56 * You can use a fixed terminal block instead of the removable terminal block system I used for TB1.  Some 5.08mm fixed screw terminal blocks have compatible PCB footprints. 
     57 * Assembly should be easy - this PCB requires only standard through hole soldering techniques.
