All hx19 receivers are shipped with a pigtail ribbon cable lead, it is easy
enough to connect supply power to the leads (see below), in this case the
front lid never needs to be open.
Easy startup is to go and get a Br2032 or Cr2032 lithium coin type battery
from your nearest hardware shop and plug it into the holder as shown on
the left. The blue LED will flash ones when the device has sufficient
power. Receivers are not shipped in battery mode so the receiver will
demand more current than necessary or 25mA, this will drain a standard
lithium battery down in a few hours. To extend the battery life use
hx19access to place the receiver in battery savings mode (see manual).
Please note that when in battery mode the device needs to be driven by
the sync option in the hx19access program.
MicroMatch plug is shown on the right, and the
image on the left shows the microMatch
plugged into the hx19r receiver. As a rule of
thumb the conductor closest to the edge of the
microMatch plug is always ground or negative
reference. Wrong polarization is not harmful to
the device, when power is correctly applied the
blue LED flashes ones.
Pin Configuration
6. Ground (Neg. Reference) (brown)
5. Default Parameters (Red) (see manual)
4. Power Input 3-4.5 Vdc (Orange)
3. Serial out Com pin (see manual)
2. Do not connect (reserved)
1. Do not connect or use
The microMatch plug can only go in one way.
To remove the battery lid, press on the bottom
of the lid by the cable opening as shown on the
left, and try to apply 45 degree force upward. In
case the lid is being closed use the same
method but apply the 45 degree force
downward.

A micromatch cable can be
created with one squeeze
using standard pliers as
shown below. The cable is
placed under the strain-relief
and the contacts pressed
in.

Using the Serial Output pin HX19R version 2.4 and above
Distance data is available on a serial output wire from the hx19receiver. This feature allows the user to read
broadcasted data as it streams directly from the receiver through a wire. The serial output has a TTL format, i.e.
inversed RS232 and the baud rate is 250Kbaud. Identification of the receiver and tag, plus the distance from the
receiver to tag comes streaming through this port pin (wire). For hx19 devices this wire is typically the fourth
from the ground wire on the ribbon cable.
Many devices are available that can utilize TTL serial data, FTDI serial to USB is very common and available
device that turns a USB port into a COM port or a serial port. The hx19 devices interface directly to this device.

The ground or negative reference on the hx19receiver usually closest to the edge of the micromatch plug
connects directly to the GND pad (soldered one). VCC pad is soldered to the third wire counting the ground
wire as number one. The fourth wire from the ground is the serial output, and it is soldered directly to the
RXD pad.
FTDI devices are very common and available, and will interface many operating systems to COM I/O.
Whatever devices used, make sure they are able to read 3.2V signals.
Hx19access is really just a simple terminal program; it can be used to read both data that comes from the
hx19ms through RF wireless and data coming through hx19r wire simultaneously. The hx19ms uses FTDI
drivers too. E.g. plug the hx19ms into a USB port and set the port to COM5, plug the hx19r wire interface into
another USB port and set it to COM3. Then put a hx19access.exe into a directory holding port.txt file
containing 5 (port number), and put another hx19access.exe into a separate directory holding port.txt file
containing 3 (port number). Then run both hx19access.exe, and both privately wired and wireless network
data should be visible.
