PT 100 Serial DAQ

I require low cost serial (RS 232 or RS 485) DAQ's for large scale deployment and hence cost is a key issue. The DAQ should have active ports i.e. provide power to the sensors. The serial interface should support hex/ASCII commands for data acquisition.
Advantech has a single channel RTD module, the ADAM-4013, that supposedly talks over RS-485 (protocol not mentioned) or the ADAM-4015, a 6-ch RTD Module with Modbus RTU.

As things go, Advantech's server was unwilling to share its files with me, so you'll have to Google if either appeals to you.
