rantonides Posted July 9, 2012 Report Share Posted July 9, 2012 Hi, I'm trying to get a Unitronics V570 to communicate to a Red Lion Data Station Plus over RS232. The documentation seems to only talk about RS485 and Ethernet, but Red lion Crimson lets me set up the driver on the RS232 port. Unfortunately, I need the RS485 on the Red Lion for something else... Cabling: RED LION RS232 V570 Port 2 RX (2) - (3) TXD TX (5) - (4) RXD GND(3) - (5) GND On the Red Lion, I set it up for PCOM ASCII protocol 9600,8,N,1 On the Unitronics, I do a COM INIT on Power Up for COM2. They just don't talk. I see the transmit light blink on the Red Lion, but nothing on the receive. Anybody else tried this successfully? Thanks for your time, Rob Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted July 10, 2012 MVP 2023 Report Share Posted July 10, 2012 ASCII is typically 7,E,1. 8,N,1 is usually RTU. Have you looked at the V570's serial port monitor (part of info mode) to see what characters you're getting? Joe T. Quote Link to comment Share on other sites More sharing options...
External Moderators Nacho Posted July 10, 2012 External Moderators Report Share Posted July 10, 2012 does Red Lion support PCOM protocol? I did not know. Is there info about it in internet? Quote Link to comment Share on other sites More sharing options...
Jenkins Posted July 10, 2012 Report Share Posted July 10, 2012 Yes the Red Lion support PCOM http://www.redlion.net/Support/Downloads/CablesandDrivers/G3/Unitronics.html Quote Link to comment Share on other sites More sharing options...
Damian Posted July 11, 2012 Report Share Posted July 11, 2012 It works for me using all the same settings and the same wiring you show. Make sure your dip-switches for com2 on the V570 are set to RS232 and not RS485. It should go Up, Up, Up, Down, Up, Down {up=on dn=off} Re-check your wiring. These little RJ11 jacks are easy to transpose. In the Installation manual for the V570 they show the pins in order 1-6, but the picture is rotated so 1 starts at the bottom and 6 is at the top. If you want, post your files and I can take a quick scan to see if I spot any program/config issues. Quote Link to comment Share on other sites More sharing options...
External Moderators Nacho Posted July 11, 2012 External Moderators Report Share Posted July 11, 2012 @Jenkins thanks for the link @rantonides In the documentation I see in the link the cabling is different than your. look at the page 2: http://www.redlion.net/Support/InfoSheet/G3-Unitronics.pdf Quote Link to comment Share on other sites More sharing options...
Damian Posted July 11, 2012 Report Share Posted July 11, 2012 @Jenkins thanks for the link @rantonides In the documentation I see in the link the cabling is different than your. look at the page 2: http://www.redlion.n...-Unitronics.pdf Nacho, the wiring he lists in his post is correct. The document you linked is for a different protocol and talking to an M90 series controller. Quote Link to comment Share on other sites More sharing options...
External Moderators Nacho Posted July 13, 2012 External Moderators Report Share Posted July 13, 2012 Nacho, the wiring he lists in his post is correct. The document you linked is for a different protocol and talking to an M90 series controller. I don't understand you, the protocol of the document is PCOM ASCII, Either M90 or Vision. Red Lion just says that Verified Device was a M90-19-B1A Quote Link to comment Share on other sites More sharing options...
Damian Posted July 13, 2012 Report Share Posted July 13, 2012 They have a separate document related to the M90 series http://www.redlion.n...-Unitronics.pdf The driver tested with the Vision series is http://www.redlion.n...t/G3_PCOM_A.pdf The difference in the cabling is only that on one they show the direct connection between the two whereas on the other they show it using an intermediate RJ to 9pin cable in between. I believe the driver labeled "Master" is the one required for the M90, and "PCOM ASCII Master" for Vision. See below... In any event, I was able to get it working fine with the same setup in his original post. Quote Link to comment Share on other sites More sharing options...
External Moderators Nacho Posted July 17, 2012 External Moderators Report Share Posted July 17, 2012 I see, Red Lion have three drivers when Unitronics PCOM have two ways "ASCII" and "Binarian". Anyway, does work @rantonides? Quote Link to comment Share on other sites More sharing options...
rantonides Posted July 20, 2012 Author Report Share Posted July 20, 2012 Yup. Works great now. Funny thing. It wasn't working and then I went to the serial port monitor and it starting working. It could be I had a bad connection on the RJ connector and bumped it coincidentally. It would be nice if Red Lion updated their documentation for other Unitronics controllers. I'm using the Red Lion DSPLE000 which works great for converting Unitronics protocol to just about any other device you'd want to talk to. Price isn't bad either at around $600 CDN (for how powerful it is). Quote Link to comment Share on other sites More sharing options...
