HUNG WAI DTEX PS S, DTEX PS M User Manual

Specification for Product Selector V1.2

1. USB connector or 4pin 2.0 connector: connect to Media Player or
other unit to communicate with each other, also can get the power
from this connector(Just Host Device, and the protocol please see
point 9)

2. Pairing Key and Pairing Indicator: Pairing Key is used to pair the
host device and slave device, right now one host device can pair
with up to 32 pcs slave devices with ID from 1 to 32. Pairing
Indicator can indicate if the device is working on pairing mode and
success for pairing
Pairing: 2.1. Set the host mode and slave mode on the device
according to the below information(Point 6)

2.2. Press and hold th e Pairing Key, and then power on,
after 5 seconds, the Pairing Indicator will flash to indicate the
device are working in pairing mode

2.3. Setting the slav e device to pairing mode one by one
and then setting the host device to pairing mode.

2.4. After pairing succe ss, the Pairing Indicator will be on

2.5. After all the de vice pairing success, power off the
devices or wait 20seconds for auto reset.

3. Reset Key: Reset the system

4. Mode and ID setting switch:

Host/Slave mode setting: There are two resistors for Host or Slave
mode setting. Shown as the pictures below:

When R41 is connected, the device is working on Host Mode;

and when R49 is connected, the device is working in Slave
mode.
When in host mode, there is a pin setting to set the bit rate to
9600bps or 19200bps. We used ID1 for this setting. When
ID1 is short, the bit rate is set to 19200bps, and when ID1 is
open, the bit rate is set to 9600bps.
When in host mode, there is 3 pin setting (ID4, 5, 6) to set
the quantity of slave device. When ID4 is short, the host
support to 8 pcs slave device; and when ID5 is short, the
host device support to 16 pcs slave device; when ID4 & 5 are
short, the host device support to 24 pcs slave device; and
when ID6 is short, the host device support to 32 pcs salve

device.
When device is working in Slave mode, the 8x3 jumper connector
is used for ID setting. As the picture below showed:

In the new device, we have change the ID setting mode. The ID
setting was divided to single digit and tens digit.
1-5 and 12-16, total 10 pins have changed to the single digit (1-1,
2-2, 3-3, 4-4, 5-5, 12-6, 13-7, 14-8,15-9, 16-10, none-0); and 6-8,
total 3pins have changed to tens digit (6-10, 7-20, 8-30).
When set the slave ID, we need to short the single digit and/or tens
digit.
Such as if we set the slave ID as ID9, then we need short the
current pin 15. If we set the salve ID as ID10, then we need short
the pin 16 (or short pin 6). If we set the salve ID as ID20,then we
need short the pin 7 (or short pin 6 and pin 16); If we set the slave
