Can ConnectPort TS16 support RS232 +/-13V electrical interface device?

We have a very old device (about 30yrs old) with RS232 Interface. The Tx/Rx only support +/-13V signalling. Thus, I would like to know that the PORTSERVER TS16 whether can support this type electrical interface or not. If the answer is negative, any other model’s TS can support this type interface? Thank you!
