PureTec

3.1 Printer Port: The PureTec can be connected to a PC for data collection or to a SciLog
Printer via the female DB9 RS-232 port labeled “Printer”. You need a SciLog RS-232
cable (P/N 080-073) to connect to a PC for data archival. Alternatively, a USB cable
(090-158) may be used. A printer cable (080-096) is required to make the connection
between the SciLog serial printer and the PureTec. As both are available, one may gather
data in both methods simultaneously.
3.2 Scale Ports: The male DB9 ports labeled “S1”, “S2” and “S3” are RS-232 ports for
electronic scales. For the PureTec, only S1 is used. (Please do not remove the covers
on the unused ports.) This port allows you to interface with a number of different
electronic scales: i.e. Mettler, Ohaus, and Sartorius top-loading scales. The following
scale cables are required:
Mettler: PGS, PM, Viper Models: P/N: 080-067PGS
Ohaus: GT, “Precision Advanced” & “Explorer” & “Voyager” Models:
P/N: 080-066
Ohaus: IP Series High Capacity: P/N: 080-067
Ohaus: Adventurer Pro Series: P/N: 080-067PGS
Sartorius: Most Series Balances : P/N: 080-068
In the PureTec Setup: Scale mode, select the scale manufacturer; the PureTec will
automatically implement the correct communications parameters. Check that the proper
communications parameters are also implemented in the scale being used.
3.3 Pressure Sensor Ports: RJ11 Telephone jacks for the SciPres disposable
Pressure Sensors, labeled “P1”, “P2”, and “P3”. The disposable pressure sensors
plug into these jacks using the included cables.
3.4 Temperature Probe Port: The SciTemp disposable Temperature Senor connects
to this port with a twist-lock connector cable. Temperature is measured in
degrees Celsius.
3.5 Valve V Port: Not used in conjunction with the PureTec.
3.6 USB Port: Used for connection to a PC, providing a Com Port. Can be used for
data collection as an alternative to the Printer port. The driver is included on the
CD that contains this manual.
3.7 Ethernet Port: Used for connection to the PureTec via a LAN. IP Address,
Subnet Mask, and Gateway are configured in the Setup menu. The
communication protocol is Modbus TCP/IP, and a list of registers is in the
appendix of this manual. (When available.)
