2. Device feat res
2.1. MultiPath APRS packets dec ding
In PLXDigi device we resigned fr m hardware packet dec ding meth d. MultiPath
APRS packet dec ding alg rithm is a digital signal pr cessing based meth d utilizing
features f m dern 32-bit micr c ntr llers used in ur devices.
MultiPath dec ding all ws t dec de received packets simultane usly by tw
dec ding alg rithms, with different digital filters applied t b th paths. Packets
dist rted by l w-frequency c mp nents r with imbalanced 1200/2200Hz t nes are
prefiltered which increases the pr bability f c rrect packet dec ding.
2.2. APRS client
PLXDigi all ws y u t generate APRS data packets with inf rmati n field defined
by user and send them in a specified interval. In this way, it is p ssible t send beac ns,
bjects, weather and telemetry data.
2.3. APRS digipeater
The main purp se f the device is receiving and sending APRS data packets via
amateur radi transceiver. PLXDigi is capable f receiving an APRS packet, dec ding the
sender, recipent, path and inf rmati n field. Then acti ns are perf rmed in acc rdance
with the pti ns c nfigured by user:
•Packet is digipeated via the APRS netw rk,
•Packet is ign red if it was c rrupted.
Device firmware implements the f ll wing mechanisms:
•Checksum Verificati n - packets with err rs are ign red,
•Anti-fl d - packets repeated in a sh rt time interval are n t f rwarded,
•Path checking - a decisi n whether t digipeat a packet r n t is made using a
filter st red in c nfigurati n data f the device. User defines whether t f rward
WIDE1-1, WIDEn-N, SPn-N, r l cal path packets and the maximum value f N (s
called New-N paradigm),
•Callsign filter - a simple callsign filter all ws y u t add stati ns t black list
(these stati ns will be ign red) r white list ( nly these stati ns will be
digipeated).
2.4. Weather stati n supp rt
PLXDigi all ws y u t receive weather data fr m c mpatible weather stati ns
ver RS-232 serial interface. Currently supp rted stati ns are:
•LaCr sse/Techn line WS-2300,
•LaCr sse/Techn line WS-2350,
•Peet Br s Ultimeter 100,
•Peet Br s Ultimeter 800,
•Peet Br s Ultimeter 2000,
•Peet Br s Ultimeter 2100,
•Davis Vantage Pr (with RS-232 datal gger),
•Davis Vantage Pr 2 (with RS-232 datal gger),
4

•Davis Vantage Pr Plus (with RS-232 datal gger),
•Davis Vantage Pr 2 Plus (with RS-232 datal gger),
2.5. Telemetry rep rts
Device all ws y u t send telemetry rep rts t APRS netw rk. P ssible telemetry
channels are:
•input v ltage,
•received APRS packets in 1 h ur r 10 minutes wind w,
•digipeated APRS packets in 1 h ur r 10 minutes wind w,
•packet dec ding efficiency in 1 h ur wind w r in the wh le range fr m device
p wer-up,
2.6. WXTelemetry m dule supp rt (anal g channels)
Y u can get m re telemetry rep rt pti ns when using external WXTelemetry
m dule. With WXTelemetry m dule y u can measure and send f ll wing values:
•tw current measurement inputs,
•tw v ltage measurement inputs,
•DS18B20 digital therm meter input.
2.7. WXTelemetry m dule supp rt (anal g channels)
Y u can use an additi nal WXBits m dule f r rep rting f digital input channels
and administrati n f utput channels. WXBits is a m dule which includes:
•4 pt c upler digital inputs,
•4 m sfet transist r pen-c llect r utputs.
States f b th inputs and utputs can be rep rted in APRS telemetry rep rts and utputs
can als be c ntr lled via serial p rt c ns le.
2.8. Firmware and c nfigurati n updates
In PLXDigi y u can d all firmware and c nfigurati n updates ver an USB cable
c nnecti n fr m y ur PC using a simple C nfigurat r applicati n.

3. Connectors and device stat s leds
3.1. Fr nt panel
There are 3 leds n the fr nt panel that sh w the status f device perati n. The
f ll wing image sh ws the l cati n f fr nt panel LEDs and c nnect rs.
Leds:
•Green LED - illuminates when receiving a signal fr m the radi (indicates the
channel is busy),
•Yellow LED - lights during transmissi n, when the device sends an APRS data
packet,
•Red LED – blinking is dependent n current device state:
•ne sh rt blink (0.1 sec nd) per 1.6 sec nds – in idle state,
•tw sh rt blinks (0.1 sec nd each) per 1.6 sec nds – when a weather rep rt
is received fr m weather stati n,
•ne l ng blink (1 sec nd) per 1.6 sec nds – APRS packet was pr perly
received.
C nnect rs:
•Mini DIN 6-pin – tw RS-232 serial data interfaces,
•Mini USB - a mini USB s cket, used t c nnect t a c mputer f r c nfigurati n,
3.2. Rear panel
C nnect rs:
•DB9 male connector – used f r c nnecti n f supply v ltage, radi , and RS-485
telemetry m dule.
6

4. Power, radio, RS-485 connector
DB-9 male c nnect r is used f r supply v ltage input, audi in, audi ut, PTT,
and RS-485 bus f r telemetry.
DB9 c nnect r pins descripti n:
•Pin 1 – PTT utput, pen c llect r, if the external PTT utput is selected in
device c nfigurati n, this pin is sh rted t gr und while br adcasting,
•Pin 2 – GND,
•Pin 3 – GND,
•Pin 4 – APRS audi input fr m radi t PLXDigi,
•Pin 5 – GND,
•Pin 6 – RS-485 A+ p sitive differential input/ utput,
•Pin 7 – RS-485 B- negative differential input/ utput,
•Pin 8 – APRS audi utput fr m the device t the micr ph ne input f the radi .
This utput als acts as a PTT by sh rting pin t gr und thr ugh a 2k2 resist r - an
pti n f r p rtable radi s that d n t have a separate PTT input (selectable in
c nfigurati n s ftware, 2k2 resist r is built-in),
•Pin 9 – supply v ltage input.
F r handheld radi s which use 2k2 resist r n micr ph ne input line y u d n't need t
use any external resist r r external PTT (pin 6) utput. C nnect pins: 2 (audi utput),
4 (audi input), 5 (gr und) and set “PTT:” t “2k2 resist r” in device c nfigurati n. 2k2
resist r is l cated inside f the device.
If y u are g ing t use b th WXTelemetry and WXBits external telemetry m dules, y u
sh uld c nnect them in a chained style: A+ and B- pair g fr m PLXDigi t first telemetry
m dule, and then fr m first telemetry m dule t the sec nd ne. Fr m a schematic
p int f view, b th m dules must be c nnected in parallel (A+ fr m PLXDigi g es t A+ f
the first m dule, and then t A+ f the sec nd, similarly with B-). Never c nnect A+ t
B-.

4.1. Audi utput level regulati n
There is 1kOhm p tenti meter n the device audi utput. Cl ckwise turn
increases audi utput level, c unter-cl ckwise decreases. Audi utput level is
regulated after pr ducti n t s me default value. The m st suitable value is dependent
n the radi used, because f vari us input impedance f different radi s (f r example,
m st M t r la GM-300/GM-350 radi s have a str ng DC v ltage bias n the fr nt audi
input c nnect r, s the utput driver sh uld be set t drive a str nger signal n the
utput t verc me this bias v ltage). If y u need t adjust utput level, y u can use a
p tenti meter l cated inside the device. T d that, y u will need t pen the case and
gain access t the PCB f the device. Output signal sh uld be set t achieve the desired
m dulati n depth at the RF utput f the radi .
S me radi s with dedicated “DATA” c nnect r demand a very l w signal level n the
input (f r example 40mV) f r pr per m dulati n depth. In these situati ns y u sh uld
rem ve 1:10 divider jumper (t enable divider) and als regulate p tenti meter utput
carefully f r best results.
4.2. Audi input level
Audi input level sh uld be regulated f r pr per packet dec ding. In m st cases
the default p tenti meter setting sh uld w rk but it can be trimmed t get the best
results. After every received packet y u can bserve rep rted signal level via serial
c ns le c nnecti n t y ur device (with “debug ax25 n” c mmand applied). The best
results are btained with rep rted signal level ab ve 40% and bel w 70%.
There is a 1kOhm p tenti meter n the input (starting with September 2013 we
replaced 1kOhm resist r with 10kOhm f r better interfacing with weak signals fr m
“DATA” c nnect r f s me radi s). Cl ckwise turn increases audi utput level, c unter-
cl ckwise decreases. The best meth d f r first try is t set it t a neutral center
p siti n. Audi input after the p tenti meter sh uld n t exceed ab ut 400mV (t av id
signal clipping) and sh uld n t be bel w 50mV. S n device input y u sh uld pr vide
audi level f ar und 100-800mV (f r p tenti meter in neutral p siti n).
The level f input and utput sh uld be individualized in such a way that packets are
dec ded c rrectly. Audi levels can be regulated using p tenti meters placed n a PCB
inside f the device.
8

Our tests revealed that dec ding w rks fine f r wide range f audi input levels. Packets
were dec ded pr perly even with audi input ver-driven with high-level audi signal
fr m speaker utputs. Similarly packets were dec ded even with signal level as l w as
5% f the ADC c nversi n range

5. Serial ports connector
In PLXDigi the MINI DIN 6pin female c nnect r is used f r RS-232 serial p rts and
5V v ltage utput.
MINI DIN 6pin c nnect r pins descripti n:
•Pin 6 – RS-232 P rt 1 RXD,
•Pin 4 – RS-232 P rt 2 TXD,
•Pin 2 – GND,
•Pin 1 – 5V utput, d n t sh rt-circuit, max. current 100mA,
•Pin 3 – RS-232 P rt 1 TXD,
•Pin 5 – RS-232 P rt 2 RXD.
RS-232 P rt 1 and P rt 2 functi ns are selectable in s ftware.

6. Connecting the weather station
6.1. LaCr sse/Techn line WS-2300, WS-2350 stati ns
These stati ns are s meh w pr blematic when y u try t use them with RS-232
interfaces ther than pers nal c mputer serial p rts.
WS-23XX stati ns need an additi nal p larizati n p sitive and negative v ltage n
pin 4 and pin 7 f DB9 c nnect r. F r that purp se we can use ur 5V v ltage utput, but
we will als need t use the sec nd RS-232 p rt's TXD line f r negative v ltage
p larizati n. If y u want t use WS-23XX weather stati ns, y u will n t be able t use
y ur sec nd RS-232 p rt f r any ther purp se (s b th p rts are used by WS-23XX
weather stati ns).
F r WS-23XX weather stati ns y u can use ur prebuilt cable: “CAB02 - PLXDigi serial
interface cable (f r WS-23XX)”.
6.2. Peet Br s Ultimeter stati ns
F r Peet Br s Ultimeter weather stati ns, y u need t use RXD, TXD, and GND
lines f PLXDigi serial interface. Stati ns must then be manually switched t "data
l gger" m de. Acc rding t the manufacturer's instructi ns, y u sh uld press CLEAR +
WIND SPEED butt ns f r 3 sec nds t activate the "data l gger".
F r Peet Br s weather stati ns y u can use ur prebuilt cable: “CAB01 - PLXDigi serial
interface cable”.
6.3. Davis Vantage stati ns
T c nnect PLXDigi t Davis weather stati ns y u need t use an additi nal RS-232
“datal gger” interface available fr m the manufacturer. Device part number is
06510SER. Y u need t use RXD, TXD and GND lines f PLXDigi serial interface.
F r Davis weather stati ns y u can use ur prebuilt cable: “CAB01 - PLXDigi serial
interface cable”.
Davis stati ns datal gger interface c mes in tw kinds: “standard” datal gger r “APRS”
datal gger. Acc rding t my current kn wledge, b th types w rk fine with PLXDigi (it
d esn't use an “APRS” feature f datal gger but “APRS” datal gger has als the same
c mmunicati n pti ns like “standard” ne).

7. Connecting to PC
C nfigurati n f PLXDigi can be d ne via USB interface with PLXDigi C nfigurat r
s ftware.
PLXDigi enters int c nfigurati n m de nly when USB cable is detected while p wering
up and it is indicated by Red LED blinking.
T c nnect t y ur c mputer, f ll w these steps:
•Disc nnect PLXDigi DB-9 cable, device sh uld be unp wered,
•C nnect the USB cable fr m y ur c mputer t PLXDigi, Red LED sh uld start t
blink (device is n w p wered fr m USB),
•N w y u can use PLXDigi C nfigurat r f r device c nfigurati n read/write r
firmware update.
PLXDigi device appears as USB-HID device in Wind ws perating system, and sh uld be
detected aut matically. Theref re y u d n't need t install any device drivers f r
PLXDigi.
N w y u can simply use PLXDigi C nfigurat r applicati n t read, m dify, write
c nfigurati n t the device. The f ll wing image sh ws the applicati n wind w.
12

7. Description of config ration software
In this chapter we will discuss all the C nfigurat r applicati n settings and describe its
influence n the device perati n.
7.1. Reading c nfigurati n fr m the device
T read the c nfigurati n fr m the device y u must use the “Read config”
butt n. After this acti n, the pr gram will d wnl ad current c nfigurati n values fr m
PLXDigi internal mem ry.
7.2. Writing c nfigurati n t the device
After entering c nfigurati n values in C nfigurat r applicati n, ch se “Write
config” t upl ad current c nfigurati n t PLXDigi internal mem ry.
7.3. Firmware update
If there is a new s ftware update, y u sh uld upl ad the new firmware attached
t PLXDigi C nfigurat r s ftware package. F r this purp se, click n the “Upload
firmware” butt n, this perati n will pen a file selecti n wind w. Fr m PLXDigi
C nfigurat r f lder please select the firmware file plxdigi_firmware_vXXX.hash (where
XXX is the next versi n f the firmware). Then wait f r the update t c mplete.
D n't w rry, it is n t p ssible t “brick” r damage the device with this perati n. If
anything g es bad, y u will simply need t try again with firmware update functi n.
Please remember that y u sh uld update y ur device with the same C nfigurat r and
firmware versi n numbers. It is als always necessary t upl ad new c nfigurati n after
flashing the device with new firmware versi ns. The device will n t start if c nfigurati n
and firmware versi ns d n t match. If y ur device simply blinks all the leds when
p wered up, it means that y ur c nfigurati n versi n d es n t match firmware versi n.
7.4. C nfigurati n imp rt/exp rt
With “Save to file” butt n y u can exp rt y ur current c nfigurati n fr m PLXDigi
C nfigurat r wind w t a file n y ur PC's disk drive. Similarly with “Read from file”
butt n y u can imp rt c nfigurati n fr m a file t y ur PLXDigi C nfigurat r applicati n.
These functi ns can be used t save y ur device's c nfigurati n and t transfer y ur
device's c nfigurati n t recent C nfigurat r and firmware versi ns.
13

7.5. Radi Tab
•“Callsign” – The callsign f y ur stati n with SSID extensi n. This field can be up
t 6 characters l ng. The default SSID is 0 and all wed SSID's are between 0 and
15,
•“Latit de” - n rth-s uth p siti n f y ur radi stati n,
•“Longit de” - east-west p siti n f y ur radi stati n.
F r APRS beac ns latitude is enc ded as “XXYY.ZZD” where XX are degrees, YY are
sec nds (1/60 f a degree), ZZ are hundredths f sec nds (1/100), D can be N f r n rth
r S f r s uth.
L ngitude is enc ded as “XXXYY.ZZD” where XXX are degrees, YY are sec nds (1/60 f a
degree), ZZ are hundredths f sec nds (1/100), D can be E f r east r W f r west.
Y u can easily find y ur c rdinates in APRS f rmat n aprs.fi map, they are displayed in
upper-left c rner f the screen.
•“TX delay (ms)” – Delay time in millisec nds f r sending an APRS packet. It is the
length f preamble sent bef re packet and necessary f r radi receivers t
synchr nize with ur packet. The rec mmended value is n t less than 250ms,
•“Q iet time (ms)” – Minimum time ff after the radi channel is busy. After this
time next packet can be sent fr m the transmit buffer,
•“Randomize q iet time” - this pti n adds s me rand mizati n t Quiet time
value which changes every packet sent with a range selected in this b x,
•“PTT” – push-t -talk utput selecti n, we can ch se between tw pti ns:
•“separate o tp t” – PTT utput pin is sh rted t gr und while
br adcasting,
14

•“2k2 resistor” - audi utput is sh rted t gr und via 2k2 Ohm resist r,
functi n used in s me handheld radi s f r transmissi n enable,
•“Sq elch level” - this a squelch level selecti n, with l wer values usable signal
will be detected with l wer signal amplitude. Default value f 1 sh uld be the
best pti n,
•“Channel b sy detect” - This pti n selects if channel busy is detected by input
signal amplitude (“analog signal level”) r with pr per packet start detecti n
(“digital detect”). The sec nd pti n all ws t w rk with pen-squelch n the
radi , but it can lead t s me packet c llisi ns. The first pti n is default and
sh uld be used in m st cases,
•“Consec tive packet send” - this pti n will make y ur device send all the
packets fr m TX queue ne after an ther with ut any delays (“in b rsts”), r
with TX delay, Quiet time, and channel busy detecti n between every packet
(“separately”). The first ne is default and used by m st APRS devices.
If y u are new t APRS r if y u are running the device f r the first time, y u sh uld
change Callsign, Latitude and L ngitude field t pr per values f r y ur stati n. These
fields are imp rtant. Y u sh uld als change PTT pti n t be c mpatible with y ur radi
c nnecti n. Other pti ns can be left unchanged as default values sh uld w rk fine.
7.6. Digipeater Tab
•“Digipeater on” – Enables r disables a functi n f RF APRS packets digipeating,
•“D plicate checking (s)” – Time in sec nds after which the next packet will be
f rwarded, if it has the same c ntent as the previ us ne. This functi n all ws
y u t ign re stati ns, which are fl ding the netw rk and als t ign re packets
15

which were heard a while bef re and are heard again after being digipeated by
ther stati ns,
•“New-N Paradigm PATH filter r les” – here y u can insert New-N Paradigm paths
t be handled by PLXDigi digipeater functi n:
•“Path (n-N)” – path name, WIDE, SP, etc.
•“N>=” and “N<=” – minimum and maximum N f r path t be f rwarded,
f r example WIDEn-N with N>=1 and N<=3 will f rward paths: WIDE3-3,
WIDE3-2, WIDE3-1, WIDE2-2, WIDE2-1, WIDE1-1,
•“traceable” – if Yes, PLXDigi will add its wn callsign t the path, if N , it
will n t d that,
•“active” – if n t checked, current r w will n t be active.
•“CALLSIGN filter r les” - here y u can define “black list” (“General r le:” set t
“Allow all, except below” - all callsigns will be digipeated except listed bel w),
r “white list” (“General r le:” set t “Deny all, except below” - nly callsigns
listed bel w will be digipeated).
If y u are new t APRS r if y u are running the device f r the first time, y u can leave
all the pti ns as default. By default, the device will digipeat all packets with WIDEn-N
string in path and als l cal P lish SPn-N string (if y u are n t fr m P land y u can
rem ve SP fr m the sec nd r w, it is placed here as an example f a l cal New-N path).
7.7. Beac ns Tab
•“Dest” – destinati n field f a beac n packet. It w uld be best t leave it default
which will all w y ur device t be rec gnized as PLXDigi (and added t w rking
stati ns callsign list n my webpage),
16

•“Path” – APRS path (default value f WIDE2-2 will all w y ur device t be
digipeated by m st nearby digipeaters), if y u leave this field empty, beac n will
be sent with ut path,
•“RF[min]“ – beac n transmit rate t RF (expressed in minutes), beac n will n t
be sent if this field is set t 0,
•“Message“ – APRS packet inf rmati n field c ntent. Beac n will n t be sent if this
field is left empty.
T pr perly generate a message field structure, please read the inf rmati n n the APRS
packet f rmat. I rec mmend the website f the P lish APRS Gr up's f under Andrew
Bart sz SP3LYR, where all is nicely described (in P lish): http://www.aprs.pl.
Example beac n packet:
@<date>z<lat>/<long>-PLXDigi U=<volt>V
•@ - APRS data ID,
•<date>z – time and date in the f rmat DDHHMM (day/h ur/minute),
•<lat>/<l ng> - stati n latitude and l ngitude,
•„-” - t gether with “/” sign between <lat> and <l ng> defines a stati n symb l
(H use in this example), please refer t the table f symb ls at
http://aprs.pl/ik ny.htm,
•PLXDigi U=<v lt>V – beac n inf rmati n field, <v lt> will be replaced with input
v ltage reading.
As y u can see in the ab ve example, PLXDigi all ws t use s me special strings, which
are aut matically replaced with c rresp nding values:
•<date> - inserts current date in DDHHMM (day/h ur/minute) f rmat,
•<lat> - inserts y ur stati ns latitude defined in “Radi ” Tab,
•<l ng> inserts y ur stati ns l ngitude defined in “Radi ” Tab,
•<v lt> inserts y ur current input v ltage read by the device.
After inserting c rresp nding values example beac n packet will l k f r example like
that:
@100214z5221.60 /01653.63E-PLXDigi U=12.1V
Imp rtant n te: I s metimes see that users try t replace special <date>, <lat>, <l ng>,
<v lt> strings with direct values. Y u d n't need t d that. If y u set f r example
“<date>” string in y ur beac n, current date will be placed instead f this string. The
same f r “<lat>”, “<l ng>”, and “<v lt>”.
If y u are new t APRS r if y u are running the device f r the first time, y u can leave
all the pti ns as default. By default, the device will send standard beac n packet with
time, latitude, l ngitude and current v ltage reading b th t RF every 5 minutes. It
sh uld make y ur stati n appear n the map n aprs.fi.
17

7.8. Weather Tab
•“Weather station” - weather stati n type selecti n b x,
•“Dest” – destinati n field f a weather rep rt.
•“Path” – APRS path (default value f WIDE2-2 will all w y ur device t be
digipeated by m st nearby digipeaters), if y u leave this field empty, weather
rep rt will be sent with ut path,
