Flex 5000A RX2 Input

I have a 5000A with dual RX that I have been using for some time. I decided to connect an antenna to the RX2 in but I get no signal at all when switching the antennas in powersdr. The Tap function works fine. I have the latest Rev RFIO board. I removed top cover and looked at schematic. There is a connector on the RFIO J13 that says RX2. The schematic shows a coax cable from that connector to the 2nd RX board. For some reason mine does not have that cable.
Is this due to some option that I dont have? I checked RX2 and the connector is there as well . Anyone have any ideas?

    Be sure on the "Antenna Selection" tab, you have "use RX1 out to RX1 in loop" UNCHECKED, or there is no RF path to RX2, unless you use RX1 Tap. Good luck, & 73. Steve

    [{"insert":"The problem is a missing coax from RFIO to RX2 so none of the RXIO functions can work, only TAP which has a different path around RFIO. Will have to see if that cable can be acquired from Flex. I need RX2 input as I want to do diversity RX.\n\nThanks\n\nGary K4MT\n"}]

    I've juggeled the switches to use ANT3 as the Receiver 1, and Receiver2 as RX1 tap. Then you'd have the common UHF connectors for the two antennas.
