Room Kit EQ Serial Port Control Issues

[davidking112]

I have two room kit EQ units with a USB to serial port adapter. This is connected to a Crestron controller via RS232. I am not getting RX response from the codec. The user LOGIN REQUIRED has been tested with ON/OFF. The baud rate and settings have been test. The USB to RS232 adapter works fine on a computer. But when connecting to the Room Kit EQ the TX signal is sent but it appears that the unit is not communicating via USB. Any suggestions?

I am using the suggested FTDI adapter, but the Room Kit EQ is still showing #500 series errors. I have a QSC connected via USB and the FTDI. The FTDI is for my Cisco custom button content source switching on the QSC. The QSC USB connection is for call status and muting. Is there any solution to these error messages? It seems to be locking up the Room Kit EQ's Web Gui preventing remote support of the unit by system administrators. We are on the 11.14.2.3 Room OS Release.
