1 • Introduction
Introduction
This section briefly describes the SDM-2012 Docking Station, the Single Module Data
Viewer Program, and the SDM-GX Docking Station PC Controller Program. This
section also describes the SDM-2012 Docking Station PC Controlled Configuration
Operator’s Manual (this document). Table 1 at the end of this section lists the SDM-
2012’s specifications.
The SDM-2012 Docking Station is an advanced, reliable system that provides
charging, calibration, bump testing, and calibration and bump test records for the GX-
2012 and Gas Tracer portable gas monitors. It is designed to save the calibration and
bump test records to a USB flash drive (standalone functionality) or to be connected
directly to a computer (PC controlled functionality). If calibration and bump test
records are stored to a USB flash drive while operating in the standalone
configuration, the Single Module Data Viewer Program can then be used with a
Windows-based personal computer to retrieve calibration and bump test data files
from the USB flash drive or from the computer’s hard drive if the files have been
transferred to the hard drive from the flash drive. If you are using the PC Controller
Program while operating in the PC controlled configuration, you may retrieve
instrument data, bump test, and calibrate up to 10 units at once. Instrument
information and data for each instrument can be viewed directly using the PC
Controller Program and can be printed from the PC Controller Program. For
instructions to use the SDM-2012 in the Standalone configuration, see the SDM-2012
Docking Station Standalone Configuration Operator’s Manual.
The purpose of this manual is to explain how to set up and use the SDM-2012 in PC

T, CAL S, EDIT ENTER, COPY, and POWER. The BUMP T, CAL S, EDIT
ENTER, and COPY control buttons are not used in the PC Controlled configuration of
the SDM-2012. The BUMP TLED and CAL SLEDs indicate the results of bump
tests and calibrations, respectively. The COPY LED does not indicate anything in the
PC Controlled configuration but will be on if the SDM-2012 was used in the
Standalone configuration and calibration and bump test records are still stored in the
SDM-2012’s memory. The CHARGE LED is located above the POWER button and
functions as a pilot LED, a system failure LED, and a charge indication LED.
The POWER button turns the SDM-2012 on and off.

USB Hub Requirements for Multiple Station Systems • 12
Front Panel
A type A USB port is located on the front of the docking station. This port can be used
to save calibration and bump test data to a USB flash drive. This USB port is for use
only in the Standalone configuration of the SDM-2012 and is not used in the PC
Controlled configuration.
NOTE: The SDM-2012 does not support connection of a computer to the front
USB port, only a USB flash drive.
USB Hub Requirements for Multiple
Station Systems
If you have more docking stations than you have available USB ports, you will need a
USB hub. RKI provides both a 4-port hub and a 7-port hub. If you have more than 7
docking stations, you will need to purchase one of each hub. Do not connect one hub
to the other. Make sure that each USB hub has its own USB port on your computer.
You may also purchase your own USB hub of any port number from your local
electronics store but it must meet the following requirements:
•USB2.0
• compatible with your Windows® operating system
An AC adapter comes with the USB hub(s) sold by RKI but does not need to be
plugged in for SDM-2012 operation. If the hub will be used to charge other devices,
the AC adapter needs to be plugged in.

Hardware Setup
This section describes how to assemble the hardware that came with the SDM-2012,
assemble a manifold, and connect calibration gas.
Hardware Assembly
The hardware assembly consists of connecting the AC adapter(s), installing the air
filter(s), installing the check valve(s), connecting the sample tubing and connecting
the USB cable(s). The SDM-GX Docking Station PC Controller software can support
1-10 SDM-2012 docking stations connected at the same time. Perform the following
steps to complete the hardware assembly for each SDM-2012:
1. Place the SDM-2012(s) on a convenient table top near an AC wall socket or
power strip in a well ventilated area. A location near a window that can be
opened is best so that the exhaust can be routed to the window.
2. If you have more than one SDM-2012, arrange them side by side as shown in
Figure 13 below. Each docking station has three connection tabs on the left
side near the bottom of the station and three connection recesses on the right
side near the bottom of the station. The tabs from one docking station can be
pushed into the recesses on another station to mechanically connect the
docking stations.
3. Insert the round plug on the end of each AC adapter’s cable into the power
jack on the back of each SDM-2012.
NOTE: If you have multiple SDM-2012s and are using a 3-port AC adapter,
plug each of the round plugs on the end of the AC adapter into the
power jack on the back of 3 separate SDM-2012s.
4. Connect the AC adapter’s wall plug into a wall AC socket or power strip.
5. Install the exhaust line, a clear 12 inch long tube with a black plastic push-on
Figure 13: SDM-2012 Arrangement

fitting, by pushing the open end of the exhaust tube onto the exhaust line
connection fitting located in the upper left corner of the instrument panel. You
may then push the black push on fitting of the exhaust line onto the exhaust
line storage fitting on the other side of the instrument panel.
6. Install the air filter to the AIR fitting of each SDM-2012 so that the arrow on the
filter that indicates direction of flow is pointing towards the AIR fitting. Push the
open end of the flexible tube that is on one end of the filter onto the AIR fitting
on the back of the SDM-2012.
7. Install the 10 foot long 5/16 inch ID flexible tube that is included with each
SDM-2012 on the exhaust fitting of each SDM-2012. Route the tube to an area
where the exhaust can be safely dispersed, such as an open window. Exhaust
tubing from multiple units can be daisy chained together in a manifold for more
convenient operation. In this case, the check valves that are provided with the
docking stations need to be used. See "Assembling a Manifold for Multiple
SDM-2012 Units" below for instructions.
CAUTION: The maximum recommended length for the exhaust tube is 10 feet. Do
not use more than 10 feet of tubing or tubing with an ID of less than
5/16 inch for the exhaust tube or the bump test and calibration
accuracy will be adversely affected. The exhaust tube that is shipped
with the SDM-2012 has an ID of 5/16 inch and is 10 feet long.

8. Install the 3 foot long 3/16 inch ID tubes that are included with the SDM-2012
on the GAS 1 and GAS 2 fittings. GAS 1 and GAS 2 tubing from multiple units
can be daisy chained together in a manifold for more convenient operation.
See "Assembling a Manifold for Multiple SDM-2012 Units" below for
instructions.
9. Connect the provided USB cord from the type B USB port on the back of the
SDM-2012 to an available USB port on your computer or to a USB hub that is
connected to your computer. See “USB Hub Requirements for Multiple Station
Systems” on page 12 for more information about USB hubs.
Assembling a Manifold for Multiple SDM-2012 Units
Up to 10 SDM-2012s can be manifolded together and draw from one gas cylinder. If
you only have standard 4-gas GX-2012s, you only need to create a manifold for the
GAS 1 fitting. If you have a standard 4-gas GX-2012 plus a %volume sensor, you will
need to create one manifold for the GAS 1 fitting and another manifold for the GAS 2
fitting. If you have a Gas Tracer of any configuration, you will need to create one
manifold for the GAS 1 fitting and another manifold for the GAS 2 fitting. The exhaust
lines can also be manifolded together and be routed away from the docking stations
with only one 10 foot long 5/16 inch piece of tubing.
Each SDM-2012 is shipped with exhaust tubing, GAS 1 and GAS 2 tubing, T-fittings
in two different sizes, and a check valve.
Exhaust Tubing
Reference Figure 15 for the instructions below.
1. Cut a 1-2” piece of 5/16 inch tubing for each SDM-2012 and connect it to each
unit’s exhaust fitting.
2. Connect the provided check valves to the short pieces of tubing already
installed at the exhaust fittings. Be sure that the arrows that appear on the
check valve are pointing away from the exhaust fitting.
3. Cut a 2-3” piece of 5/16 inch tubing for every SDM-2012 except the first one
and connect it to the other end of the check valve.
4. Insert the larger T-fittings into the tubing so that the remaining two ports on the
T-fitting are perpendicular to the exhaust tube and check valve.
5. For the first SDM-2012, cut a 9-10” piece of 5/16 inch tubing and connect it
from the check valve on the first SDM-2012 to the closest port on the second
SDM-2012’s exhaust T-fitting.
6. Use one of the provided 10 foot lengths of tubing and connect it to the T-fitting
on the last SDM-2012. The maximum recommended exhaust tube length is 10
feet.
7. For the remaining SDM-2012s, cut 6-7” pieces of 5/16 inch tubing and connect
the remaining T-fittings.
