HUB-SDM5
1. Introduction
The HUB-SDM5 is a junction box and is used to connect multiple
Synchronous Device for Measurement (SDM) or SDI-12 devices/peripherals to
a single Campbell Scientific, Inc. datalogger. The HUB-SDM5 consists of an
environmental enclosure with six weather resistant bulkhead fittings and five
terminal strips.
2. HUB-SDM5 Specifications

3. General
Inside the HUB-SDM5 enclosure are five pairs of terminal strips. These
terminal strips are mounted on a DIN rail and an orange end cap separates each
pair. Each pair of terminal strips is connected to each other by means of a
jumper. The terminal strips are used to connect up to six wires to each other.
The wires are secured to the terminal by a spring-loaded guillotine.
4. Installation and Wiring
A U-bolt is used to mount the HUB-SDM5 to a 1.25 inch NPT pipe.
The spring-loaded guillotines are opened with a small flat blade (2.5 X 50 mm)
screwdriver (p/n 8125). Orient the screwdriver blade so that the blade edge is
perpendicular to the orange separators. Gently insert the small flat blade

screwdriver into the square slot located next to the circular wire port until it
bottoms out. For the cluster of four wire ports located on the left hand side of
the HUB-SDM5, the guillotine release slot is located to the right of the wire
port. For the wire ports on the right hand side of the HUB-SDM5, the
guillotine release slot is located to the left of the wire port. Once the
screwdriver has been completely inserted and has bottomed out, firmly press
the screwdriver down until the guillotine snaps open. Insert and hold the wire
as the screwdriver is removed.
4.1 Wiring SDM Devices
Before connecting the SDM signal cable to the terminals, strip the wire
insulation back to expose ¼ inch of bare wire. Feed the cable through the
bulkhead fitting. Neatly separate the five wires into the following order, SDM
data, SDM clock, SDM enable, SDM ground, and SDM shield.

4.2 Wiring SDI-12 Devices
Before connecting the SDI-12 signal/power cable to the terminals, strip the
wire insulation back to expose ¼ inch of bare wire. Feed the cable through the
bulkhead fitting. Neatly separate the four wires into the following order, SDI12 data, SDI-12 power, SDI-12 ground, SDI-12 shield.

5. Generic Junction Box
The HUB-SDM5 can be used as a generic junction box. In its default
configuration, six, five conductor cables can be connected to each other.
Three, ten conductor cables can be connected to each other by removing the
jumper between the terminal strips. Use a small screwdriver to pry the jumper
out.

There are no user-serviceable parts in the HUB-SDM5. Make sure that all
unused bulkhead fittings are sealed with a plug and that the lid is tightly
fastened.
