BIST tests failed. Restarted both PC and computer. BISTS passesd but still will not ping. Ran extended telnet BIST. Failed Preamplifier tests (51 and 53). TUrned off SBP, EM122 PC and transducer and then turned off preamplified. Turned back on and booted EM122 back up. Re-ran preamplifier BISTS. Still failed. Start pinging- shows pings being fired in Ksync but does not show pings in SIS. Telnet shows "No attitude" messages. Possibly a problem with the pre-amplifier unit so the pings are being sent but not properly recieved.
