serial config for STU-III

2007-12-25 10:34:00

     Not much to summarize....but here it is.

     

     For definition's sake: An RCA STU-III is a Secure Telephone Unit.

     

     The serial port jumpers do need to be changed on the Ultra if you're

     using RS232 (default is RS423). Select Pins 1 and 2 on J2104 and

     J2105. If you need a documentation on it, the Sun Ultra 2 Series

     Reference Manual, Main Logic Board Jumpers, Section 4.3 Serial

     Jumpers, is what I used.

     

     A straight cable RS232 from the CPU to the STU-III is needed. A null

     cable to test the transmit from another CPU (we tested the

     transmission from a PC)

     

     Thanks to Jason Frye and Tim for their replies. They kept me on the

     right track. My original question follows the summary.

     

     Thanks,

     -----------------------------------------------

     

     Does anyone have some information on how to configure an Ultra II,

     Solaris 2.5.1, serial port for an RCA STU-III?

     

     I know that the serial port jumpers need to be done, depending on the

     signal levels, and I have some documentation on doing that .... but

     wondering what else I might need to know before I get started.

     

     Could even use some information on what kind of cable is needed.

     

     Thanks,
