Note that it's not really within the scope of this document to troubleshoot Vixen/dongle/cabling issues - please go through some of the Wiki documentation and if at all possible, try to confirm on a working piece of equipment before troubleshooting something that isn't broken to begin with. It's assumed at this point that to the best of your knowledge that everything up to the "IN" jack is in working order.

	Configure a ~~short~~ Vixen sequence with ~~a slow on/off sequence~~ for ~~each channel - 1 second on, 1 second off. Alternate~~ the ~~odd~~ channels ~~so that they are the opposite polarity of the even channels. In other words, when channel 1 is ON, channel 2 is~~ OFF ~~or when channel 2 is ON, channel 1 is off. Create a 48-channel sequence in this fashion so you can test all PICs at once. With~~ the ~~sequence running, measure the outputs of the PIC at pins 1, 13, 12, 11, 10, 9, 8 and 7~~. ~~You should see each pin alternate from 0v to 5v once a second matching the sequence. If this is not the case, then sequencing data is not being received by the PIC(s).~~		Configure a 200 channel, 10 second Vixen sequence with ALL channels ON for the first 5 seconds and ALL channels OFF for the last 5 seconds. Measure the voltage at pin 5 on PIC #1 (U1) with the same sequence looping (from ground). It should be alternating between 1.2v and 2.7v (do not worry about the exact voltages - just that there is a 1-1.5v swing) and not be stuck at one or the other. If it appears stuck, then inspect the "IN" RS-485 chip at U7 (and the entire path from it to pin 5 on PIC #1/U1 pin 5) and ensure there are no bent pins (including the RJ45 jack itself), cold solder joints. Swap the two chips at U7 and U8 ("OUT" RS-485) to see if that resolves the issue. If the failure is in-between channels, then perform the same check on pin 5 on all PICs. For PICs #2-6, pin 5 is fed from pin 6 on the preceding PIC. In other words PIC 1, pin 6 feeds PIC 2, pin 5 and down the line so it could be an issue with the preceding PIC. Swap PICs around to see if that helps - otherwise it is probably a soldering issue.

Swap PICs around to see if that helps - otherwise it is probably a soldering issue.

	If the problem is with a daisy-chained controller FROM this Ren48LSD, then inspect the RS-485 "OUT" chip closely at U8 for bent pins, solder issues, etc. Check the output RJ45 jack at J14 for crossed pins. Swap the RS-485 chip between U7 and U8 to see if that helps. Note that ALL output from the Ren48LSD is at RS-485 levels so the daisy-chained controller should not have the RS-232 jumper enabled.

FAQ

	Q2: Can I use standard DIY SSRs with the Ren48LSD?		Q2: Can I use standard DIY SSRs with the Ren48LSD?

	A2: ~~Maybe~~ - ~~but with~~ the ~~following caveats:~~		A2: You can use DC SSRs but not AC SSRs. AC SSRs cannot be used as they require synchronization to the AC power line using a zero-cross signal from the controller. The Ren48LSD does not have an AC present since it only uses a DC power supply. While it can turn on/off/dim the AC SSR, since it is not synced the TRIACs will turn on/off at the wrong times during the AC cycle and it will look terrible. DC SSRs can be used just fine - however there is one caveat in that pin 7 is not connected to ground as with other controllers (it is in fact tied to +DC). This means that the 'active' indicator used on most DC SSRs (indicating it is connected to a controller) will not work correctly. This does not affect operation at all however so they can be used with on/off/dimming just fine.
	~~:*It has~~ not ~~been tested at all~~
	~~:*The~~ power ~~LED~~ on the SSR will ~~not work as~~ there is ~~no ground fed to~~ pin 7.
	~~:*To be safe, pins 3, 5 and 7 should~~ not be connected ~~from the Ren48LSD~~ to ~~the SSR~~.
	~~:*You may want to stick with a 5vdc source only if insure of the specifications of~~ the ~~optoisolators~~ used on ~~the SSRs. If you are using the standard coop AC or~~ DC SSRs ~~then they should be able~~ to ~~use anything up to 12vdc OK~~.
	~~For these reasons, it is~~ not ~~really recommended to use an SSR~~ on ~~the Ren48LSD at this time~~.
