This section details the installation of the RSTAR Affinity data logger’s components.


The following are the tools you need to install the data logger:

• number 2 Phillips head screwdriver

• 2 mm flat head screwdriver

• 20 mm open wrench or an optional gland wrench available from RST


NOTE: The cable gland seals the connection and protects the data logger from moisture and contamination. It accepts instruments with ½” (12.70 mm) diameter cables.

To connect the cable gland to the data logger, complete the following steps:

Figure 4: Cable Gland Connection

1. Unscrew the front cover of the data logger using a screwdriver to access the service port compartment.

2. Remove the cable gland assembly from the enclosure.

3. Thread the instrument or sensor cable through the cable gland and into the enclosure.

4. Pull the terminal tab to detach the terminal block from the data logger.

5. Use a 2 mm flat head screwdriver to tighten each of the stripped instrument wire to the assigned pins on the terminal block.

6. Tighten the cable gland to seal the connection and protect the data logger from moisture and dirt.

7. Screw the front cover back on the data logger following the tightening sequence shown in Figure 5. Make sure the rubber seal on the cover is free of debris and seated in its groove before tightening the screws.

Configuration Identification Label

The data logger’s flexible design supports a variety of instruments. Specific instrument interface modules (IIM) are installed at the factory. The label on the side of the enclosure shows the data logger’s serial number and the configuration option shows as aa-bb-cc-dd-ee-f-gg-h, where:

• aa = instrument port 1 interface (sensor type and connection) *

• bb = instrument port 2 interface (sensor type and connection) *

• cc = instrument port 3 interface (sensor type and connection) *

• dd = instrument port 4 interface (sensor type and connection) *

• ee = instrument port 5 interface (sensor type and connection) *

• f = Number of batteries (1=one battery, 2=2 batteries, 3=3 batteries)

• gg = communication type and antenna (1=internal, 2=external antenna required)

• h = mounting type

Table 4 lists the instrument type, manufacturer model number, and conductor color. Custom means the interface wiring is dependent on the vendor’s cables. Check with the vendor for the appropriate color-coded pin assignment.
