+// The way this is supposed to be used is connecting a (short) 16pin flatcable from an rx daughterboard in RXA master io_rx[8..15] to slave io_rx[8..15] on RXA of slave usrp
+// This can be done with basic_rx boards or dbsrx boards
+//dbsrx: connect master-J25 to slave-J25
+//basic rx: connect J25 to slave-J25
+//CAUTION: pay attention to the lineup of your connector.
+//The red line (pin1) should be at the same side of the daughterboards on master and slave.
+//If you turnaround the cable on one end you will burn your usrp.
+
+//You cannot use a 16pin flatcable if you are using FLEX400 or FLEX2400 daughterboards, since these use a lot of the io pins.
+//You can still link them but you must use only a 2pin or 1pin cable
+//You can also use a 2-wire link. put a 2pin header on io[15],gnd of the master RXA daughterboard and connect it to io15,gnd of the slave RXA db.
+//You can use a cable like the ones found with the leds on the mainbord of a PC.
+//Make sure you don't twist the cable, otherwise you connect the sync output to ground.
+//To be save you could also just use a single wire from master io[15] to slave io[15], but this is not optimal for signal integrity.
+
+
+// Since rx_io[0] can normally be used as a refclk and is not exported on all daughterboards this line
+// still has the refclk function if you use the master/slave setup (it is not touched by the master/slave settings).
+// The master/slave circuitry will only use io pin 15 and does not touch any of the other io pins.
