## Description

Ioptron Equatorial Telescope Upgrade Control Console Cable Ieq30pro RS232 to 4P4C RJ9,6FT

Review: So Far So Good - Initial setup was pretty easy. I did have to get the CP210x USB to UART Bridge VCP Drivers for this to work on Windows 11. I was able to update firmware on my iOptron SmartEQ Pro+ and Hand Controller. It's also now working via the iOptron Commander ASCOM software in NINA. I'll circle back once I have this outside for a night or two.
Review: Worked out of the box for my Meade LX200 GPS with Windows 10Pro - I've never submitted a review before, but this worked so easily with no hassle, I thought I'd perhaps help others in the same situation. I had the GPS rollover issue with my Meade LX200 GPS mount--it reverted to 2003 and picked alignment stars that were well below the horizon. I needed to upgrade to the latest software update and did not have the official Meade USB to serial to RS232 cabling, and didn't want to spend the money for them. I tried some USB to serial adapters that I had lying around with my Windows 10 Pro laptop and none of them recognized the mount. While looking for other adapters, I stumbled on this one claiming to be for Meade for about one quarter the price of the official ones. Plus, it went from USB directly to the RJ11 style cable that the mount uses, without a serial plug in between. Some reviewers said that this cable would require downloading a pretty common driver, but in my case it was not necessary. I plugged it in and it discovered the mount immediately, no driver required. I'm not a computer wizard, but am guessing that Windows 10 may already have the driver. Worked perfectly with my computer and mount. It's rare that something works as it should.

## Questions & Answers

**Q: Will this work on ioptron ieq45 pro equatorial mount ?**
A: I use it with CEM60 and the ieq30, so I would assume it will work.

**Q: Will the ioptron variant cable work with the ioptron cem60 mount?**
A: Yep, works great with my CEM60. They should have done it this way from the factory!!

**Q: It looks as if this cable does not require a usb to serial converter. is that the case?**
A: Yes.  It plugs directly into the RS232 port (next to the guide port) on the iOptron drive.

**Q: I have a lx200 classic. can anyone confirm that this will work with it? if not can someone point me to the correct one. thank you!**
A: It has to be a 6 wire 232 to USB, not 4. Works fine with my 200 series

### ⭐⭐⭐⭐⭐ Worth the wait
*by F***. on March 22, 2018*

It works. True, I've only tested it in my living room, but if it works here it should work outside on a dew-encrusted night. The usual attachment--connecting the supplied cable through a USB-to-RS-232 adapter--seems kludgy and archaic, and seems like a potential source of failure when lying in the grass waiting to be stepped on or soaked with dew. Or coffee. This new cable seems as well-made as any, is longer than I can imagine ever needing, and works. Plus, now I have a backup. . .always a good thing when miles from home in a dark-sky site. It took a month to get here from China--hey, Letotech, can't you do any better than that??--but it was worth the wait. I hope that if a few more of us buy it, maybe they'll put a little more money into the shipping. Still, I'm grateful Letotech has made it for us, and recommend it if you have an iOptron EQ mount that needs it.
