RJ-12 to DB-15 wiring schematic

Hello everyone,

We've recently purchased the 1260 Infinity II system, and are now attempting to connect it to our old DAWN HELEOS II instrument from Wyatt.

In order to send the "injection" signal to the DAWN HELEOS, we need to connect it with a cable to the pump.

The DAWN HELEOS has an RJ-12 port, and the 1260 Infinity II pump has a 15-pin port or D-sub female 15 way connector (our previous 1200 Series pump had a 9-pin port).

There are only two wires from the RJ-12 cable that we need to connect to the pump, however we need the wiring information for the 15-pin port.

Does anyone know which pins to connect, so that the pump will transmit the injection signal to the MALS instrument?

Thanks in advance
