Docking Station/Charger: ST-DS
Description
Functional Description
The ST-DS is a microprocessor-based docking station designed to fast charge the
ST-BTP (rechargeable power pack). A fast charge occurs in one of three possible
configurations and can take between two and three hours (depending on whether the
ST-BTP is fully discharged and the amount of current drawn during the charging
process). Each situation is detailed in “Using the ST-DS to Charge the ST-BTP
(Rechargeable Power Pack)” on page 4.
1. The ST-DS charges the ST-BTP alone.
2. The ST-DS charges the ST-BTP while the rechargeable power pack is
installed in a touchpanel and the touchpanel is not in use.
3. The ST-DS charges the ST-BTP while the rechargeable power pack is
installed in a SmarTouch STS touchpanel and the touchpanel is in use.
NOTE: Configuration 2 and 3 depend on the type of Crestron wireless touchpanel
in use.
A second function of the ST-DS is to preserve the charge of the ST-BTP. As long as
the contacts of the ST-BTP and the ST-DS remain together, the ST-DS “trickle
charges” the ST-BTP in an attempt to maintain the ST-BTP for optimum
performance. The duration of a “trickle charge” is continuous as long as the ST-
BTP is not fully charged.

Physical Description
The ST-DS, shown on the next page, is housed in a black enclosure with silk-
screened labels on the front panel and cavity (docking area) of the unit. On the front
panel there are three LEDs for indicating the unit’s current status. The cavity
accommodates either the ST-BTP with optional ST-DS charging guide or, in some
cases, a Crestron wireless touchpanel with ST-BTP installed. The only wired
connection is made to the bottom of the unit. There are four rubber feet on the base
of the ST-DS for stability and to prevent slippage.

ST-DS Indicators
There are three LED indicators located on the front panel of the ST-DS. Refer to the
illustration and descriptions after this paragraph.
ST-DS Indicators
(External Power)
This green LED illuminates when power is provided to the ST-DS via the specified
external power pack.
CHG (Charge)
This red LED illuminates when a ST-BTP is inserted into the ST-DS cavity and the
contacts of each touch. The LED remains ON while the rechargeable power pack is
charging.
If the CHG LED blinks every second, it is in a "charge pending" state. This state
indicates that the rechargeable power pack may be too hot or cold, or that it has
extremely low voltage and a “trickle charge” is necessary before a fast charge can be
applied. In either case, the ST-DS monitors the ST-BTP status and waits for the
correct conditions to start a fast charge. The LED remains ON during a fast charge.
RDY (Ready)
This red LED illuminates when the ST-BTP in the ST-DS cavity is fully charged.

Setup
Power Source
The ST-DS has a DC power socket connector on the bottom of the unit. This power
connector is used to supply power via an external power pack. Crestron
recommends a power pack for the ST-DS. It is available under Crestron part
number PW-1215 (110v USA and Canada) or PWI-1215 (220v International). If an
external power pack other than these Crestron models is obtained, verify that it
meets the required specifications and polarity as shown below.
Power Pack Specifications
CRESTRON POWER PACK INPUT SPECS OUTPUT SPECS
PW-1215 120VAC 60Hz 35W 12VDC 1500mA
PWI-1215 230V~50Hz 35W 12V - - - 1500mA 18VA

Using the ST-DS to Charge the ST-BTP
(Rechargeable Power Pack)
WARNING: The ST-BTP is shipped in a discharged condition. Charge the ST-
BTP in a well ventilated area away from sparks and open flame. Do not smoke
while the ST-BTP is being charged.
WARNING: Avoid damage to the ST-BTP and possible physical harm, use only
the specified external power pack PW-1215 (110v) or PWI-1215 (220v) or
equivalent when charging with the ST-DS.
There are three possible methods of charging the ST-BTP with the ST-DS. All
methods are considered fast charging and take between two and three hours for a
fully discharged ST-BTP. Using the touchpanel during charging may take up to
three hours and is only permissible with certain Crestron wireless touchpanel
models.
Method 1: ST-BTP Alone
NOTE: Use the optional charging guide when charging the ST-BTP alone (while
it is not installed in the touchpanel).
Position the charging guide into the ST-DS cavity. Position the ST-BTP, by itself,
into the ST-DS cavity to automatically initiate charging. Be sure that the contacts of
the ST-DS and ST-BTP touch. Refer to the illustration on the next page to confirm
positioning. The CHG LED illuminates while the ST-BTP is charging. When the
ST-BTP is fully charged, the CHG LED extinguishes and the RDY LED
illuminates.

Method 2: ST-BTP Installed in an Inactive Touchpanel
NOTE: Do not use the optional charging guide when charging the ST-BTP while
installed in the touchpanel.
NOTE: This method only applies to certain Crestron wireless touchpanels.
In this method, the ST-BTP is properly installed into the touchpanel. Position the
touchpanel into the ST-DS cavity, as shown on the next page. Be sure that the
contacts of the ST-DS and ST-BTP touch. The CHG LED illuminates while the
ST-BTP is charging. When the ST-BTP is fully charged, the CHG LED
extinguishes and the RDY LED illuminates. As long as the touchpanel remains
inactive (OFF), a fully discharged ST-BTP fully charges in two hours.

Method 3: ST-BTP Installed in an Active Touchpanel
This method is identical to method 2, except that the touchpanel is active (ON)
while charging. As a result, the time to fully charge a discharged ST-BTP can take
up to three hours.
Fully Discharging the ST-BTP
Due to the memory effect of nickel-cadmium (NiCad) cells, Crestron recommends
that the ST-BTP be fully discharged for every 25 charge/discharge cycles. The
ST-BTP can be fully discharged while in the touchpanel. A button to fully discharge
the touchpanel should be available within a designated screen design. This button
has a special software identity (reserve join number) and can be recreated and
programmed onto any page in the touchpanel project. Consult your Crestron dealer
if this feature cannot be located.
