Hello, Because you cannot connect with any of the CPUs, the problem must be a common error. From the page http://www.helmholz.de/prod.d,48_56_85.html?prod=68 On the TTY side, the SSW4 uses the current sources of the remote unit, the RS232 side is powered via the RS232 status signals. One possible problem is that the 15V is defective, with as result that the current loops are not powered. On the power supply you have a LED indicating if the 15V is OK or not. |
