    Great quick reference guide, however, I'm confused. The "Flex 6400 and Flex 6600 hardware manual reference Manual "states that PTT input,TX Request, and Remote Power On inputs are 3.3 volts max . Dan's document indicates these inputs are High= +40 VDC @140 mils and Low = Ground. I "think" that the copy and paste keys got into the act.

    It is my understanding that the PTT and Remote on inputs are meant to be open and ground. The TX request can be programed as a active high or active low and will will recognize +3.3 or +5VDC as a active high active high so that TTL or or 5 volt CMOS levels will work.

    It appears that the Accessory Connector definitions continue with this level definition.

    This is a very useful time saving PDF document. Which document is correct, the manual or quick reference guide? Please correct me if I'm wrong.

    Gayle, you are correct; it is a cut-and-paste fail. Those inputs are buffered through an SN74LVC1697 and employ internal pullups. So the signal is either open (HIGH) or closed (LOW).

    Great catch! Thank you. I'll update the doc.

    73,
