OT: CSI-9800D micropatch

Post by **wavetar** » Tue Jul 27, 2004 12:19 pm

Anybody have experience with these units? Have a fire dept using one with the select call option...it answers the phone & accepts the dtmf sequence for the cap code, it then keys the radio & you hear 4 seconds of...silence! A scope on the 'audio out' line confirms no tones being output. After the two-tone sequence timing is over, it passes the phone line tx audio no problem. Any ideas? Common problem?

Ooops, my bad. It's a '9800D', not a '9000D'.

Our standard proceedure as follows:

Dial number, wait for answer.
Enter access code preceeded by a * ( *1234 )
enter 3 digit pager code, followed by a * ( 123* )
Pager tones go out.

Yes....that is the correct procedure...my problem is, the tones aren't being generated, there is 4 seconds of silence regardless of what cap code you try. Have been talking to CSI in Cali, appears to be a bad IC, U17.
