![]() ![]() This is what the IC-RP2V looks like inside: ![]() On the other hand, the repeater modules that need to do duplex require separate transmit and receive units. Since the RP2D can only operate half-duplex, it only needs an integrated transceiver. Some investigation will be required to see if the radio responds to other commands on the USB port (as defined in the ID-1 interface specification). This appears to be nothing more than perhaps an ID-1 in a rackmount case, presumably with some slightly different firmware. The pinout of this connector appears to be: There is a 16 Mbit x 8 Boot ROM (flash) (IC12), 32 Mbit x 16 Flash ROM (IC11), and 4 Mbit x 32 of SRAM (IC2, 3, 6, 7) on board.Īlso of note is that J6 is an RS-232 interface directly connected to the CPU (IC5). Interesting to note is that the ASSIST ports (ID-RP2L 10GHz link) connect via a 10MB/s ATM connection using LVDS (low voltage differential serial). Below is the block diagram of how it works. This is a picture of the ID-RP2C (click for zoom): ![]() There are some interesting things to notice when you peek under the hood of the repeater equipment. Something as simple as a manufacturing change may render this information inaccurate. While we will try to be as accurate as possible in the information we provide, there are no guarantees that it will work with your equipment. Further, you will probably be voiding your ICOM warranty, so you're on your own. Of course, it should go without saying that if you undertake any of the modifications listed on this page, you do so at your own risk. While the repeater modules look nice, there are always things that can be done to make them work better. D-STAR Modifications Repeater Modifications ![]()
