try to connect two modules: WIC-1T and WIC-2T by this cables: DB60-V35MT + V35(female)-RS232(male) + SS-RS232FC. All cables standard length, about 3 meters. This means that summary length of all cables about 6 meters. I configure this modules on 2651XM, IOS 12.3.Lights on both modules green, but "Serial1/0 is up, line protocol is down "

Hello, friends.
I try to connect two modules: WIC-1T and WIC-2T by this cables: DB60-V35MT + V35(female)-RS232(male) + SS-RS232FC. All cables standard length, about 3 meters. This means that summary length of all cables about 6 meters. I configure this modules on 2651XM, IOS 12.3.Lights on both modules green, but "Serial1/0 is up, line protocol is down "
DB60-V35MT + V35(female)-RS232(male) - are from the right side of the photo.
