I'm not familiar with that unit, but the pinout appears to match the Efratom LPRO-101 with the exception of the power supply.
On the LPRO, pin 8 is the -ve side of the 24V supply and pin 10 is the +ve side. The "19V to 32V, 24V nominal" spec also matches the LPRO. It's possible that there is more than one variant - one with a +24V supply to match the LPRO and another with a -48V supply for telecom applications.
