Any idea when Serial to USB support will be released for Spark 70D?
If you're running one of the latest software loads on your Webex Room 70D, then the Serial to USB support is already present. You just need to plug a supported USB-Serial adaptor in to the USB A port on the device (see Page 37 of the Install Guide for the location of the port - Marked as "I USB, type A" on the diagram).
The current CE software release at the date of this post is CE9.6.1.
The original Room 70 Dual devices shipped with CE9.2.0 loaded, so just one minor revision before the support was added. If you haven't ever upgraded your endpoint, that could be the cause of not having the support for the USB adaptors.
It's highly recommended that you update to the latest software release for all the bug fixes and additional features it contains.
There is no RS232/USB support on the Room 70 or Room 55 Dual at this time; the type A USB port is connected to the second display for control, therefore RS232 is disabled on that USB port. The software version does not matter. No, the type B port cannot be used either.
I just verified all this info with Cisco R&D too.
According to the Room 70 Cable Schema, there is still a spare USB Type A port available.
I haven't tried it to see if it works so cannot confirm, but if the R&D team say it won't work, then I guess that's a more definitive answer.
There is always the Micro-USB connector, but that will require you to connect something that will use the correct driver (CP210x USB to UART Bridge Virtual COM Port), so wouldn't be a direct connection from the Crestron to the Room Kit, but could give you some options on making something work.
Wayne, that is for the R70 G2, which has a dedicated COM port anyway; you would not use USB on the Pro/R70 G2 codecs.

Only the first page is the G2. The other Room devices are also listed. The “G1” Room 70
is also shown.
hello, did you ever find a solution to connecting a spark plus/roomkit/roomkit mini from the micro usb "serial" connector successfully to a DB9 or other tx/rx/gnd serial connector? I'm trying to do the same thing. I'm seeing the same thing you are - I can connect serial from my computer over putty, but it's not working from a control system like Crestron or otherwise over serial.
