Layout

Important Note: The entire solder side of the PCB is a ground plane, which will tend to absorb and redistribute heat. It is highly recommended that you use a good, temperature controlled soldering iron to assemble the board. Ordinary pen-style soldering irons may not get hot enough to make good solder connections, especially to pins that connect to the ground plane.

BOM for Rev XB Board (old PCB revision)

There are several alternatives listed below for providing a zero-crossing signal. The first choice is listed as preferred, because that is the selection that works with the Ren-T board. The second alternative is OK (requires an external low-voltage transformer). The third alternative will work also, but its use is discouraged because it requires that 110VAC be brought onto the controller board.

NOTE: This BOM is for an older version of the PCB, and is different from the BOM for the current version of the board. You need to scroll down much further to get the current BOM.

1  140-XRL16V1000-RC     1000 uF, 16V Radial-Lead Elect. Cap         C1

Note 1: The on-board regulator should only be used if measures are taken to keep the current consumption down (omitting the on-board LEDs, and using the non-PWM firmware). If the LEDs are used and the PWM firmware is installed, the current consumption of the board is about 1A, and so the regulator will dissipate too much power (the small value of C1 precludes decreasing the input voltage). If you are using an external PC power supply, you don't need these optional parts.

If the on-board regulator is used, omit the header that is designated for U1.

Note 2: The specified connectors for bringing in external power are 15μ Gold, you may change this if you have other preferences. Also, the molex calls for using a crimp tool. The ones in the mouser catalog are pretty expensive, and I don't know how well the Radio Shack ones will work.

Note 3: An alternative to the Molex power connectors is to use a modified, spare IDE disk drive Y-cable (or similar) as a pigtail from the board.

Construction Notes

1) The '+' leads of C1 and C2 go in the holes with the square pads.

2) The anodes of the status LEDs (long lead) go in the holes with the square pads.

3) The cathodes (the end with the band) of diodes D1, D4, and D5 go in the holes with the square pads.

4) The pin with the dot above it on the resistor network component should be installed in the square hole.

Errata for Rev XA PCB

 1) The trace between J4 and D1 is too small, and needs to be beefed up if the board is configured to draw more than 1/2A through J4.
 2) There are two diodes labeled D4.
 3) The holes for D1 are too small.
 4) The silkscreen reference designator for C3 (above U10) is missing.

XC PCB Current release

The first prototype, with some parts still to be fitted. Tested on Jan 20, 2008.

Connections

RS232 Input

Over short distances this board can be directly connected to an RS232 serial I/O port. The input cable can be a 9-pin straight-through cable. It should be kept as short as possible, on the order of 20 feet or less. A shunt should be installed between the two pins of JP1 when using an RS232 input source.

However, you can use the RJ45 input connector for RS232 as well. This requires that you make a custom cable from your computer to the first Renard in the chain. This means the the DB9 connector on the BOM can be omitted.

Pin Assignments:

Pin 5 - ground
Pin 3 - serial input signal.

RS485 Input/Output

These connectors may be directly connected to Ren16/Ren24(rev 3.0 and higher) and to other Ren64 board (all versions).

Pinout:

1,2 - ground
4 - RXD+/TXD- (inverting input/output of transceiver)
5 - RXD-/TXD+ (non-inverting input/output of transceiver)

Remove the shunt from JP1 for RS485 input.

Power Input

The board is designed to be powered with a 6.3VAC, 1A transformer, providing both power and a zero-crossing signal at the same time. One potential transformer for this application is the Xicon 41FD010 transformer (mouser p/n 41FD010). The center-tap of this transformer should be left open, perhaps covered with a wire nut to protect it from inadvertant short-circuits.

If all the LEDs are used in the REN64XC, a 1000mA could be used if all the channels were fully on at one time. This leaves no room for error on the transformer listed above. That being said, this is a rare happening given the way we used dimming controllers. One option is to use a 41FD030 which is a 3A version of the transformer listed above. Now the interesting thing is, at the time of this writing, the 41FD030 is actually cheaper than the smaller one. It is not a good idea to power more than one board off a single transformer.

If you do not have 120VAC power, then you may have a larger challenge. A cost effective transformer from 220VAC to 6.3VAC has not been located. There are options but you should get some expert assistance from forums members. Careful selection of resistor replacements with special care to the overall maximum input voltage is required and each case is special. Several members have located a 9VAC secondary. This is about the maximum that can be used safely due to the voltage rating on the ripple capacitor. The R1 and R2 values should be changed to 1.2k Ohm for this particular situation.

Other Connections

Pin 3 of the RJ45 serial input connector J4 is connected to pin 3 of the RJ45 serial output connector J3 with a signal trace.

Pins 7 and 8 of the RJ45 serial input connector J4 is connected to pins 7 and 8 of the serial output connector J3 with a trace capable of carrying 1A or so of current (current capacity to be verified).
