The line on witch the FSK signal is taken to, is set up with the DET jumper.
Which line has to be chosen, depends on the question where the software, which is used will expect the signal.
For DSR
+--------------------+
| ooooo IIIII:I::I + |
| ooooo :::::II::: - |
+--------------------+
For CTS
+--------------------+
| ooooo IIIII:I::: + |
| ooooo :::::II:I: - |
+--------------------+
For PD this can be the DSR or CTS line, depending on the setup in the PD.INI file. For WinFlex and PocFlex the data is expected on the DSR line.
For checking the hardware setup we recommend to test PocFlex first.
POCFLEX
Edit first the PD.INI file to perform the software setup:
; POCFLEX.INI - pocflex program configuration file
;
; NOTE: Command line arguements take priority over the settings in this
; file. Configuring the program with command line switches should
; now be considered obsolete - there are many newer program options
; that can only be set in this file.
;
;
; Filter options are set up in seperate FILTER.INI file
;
(GENERAL)
;
; Interface type : 0 = 4 level 1 = 2 level
; chose here 1 = 2 level for the Makinterface Pro
TWOLEVELINT = 1
;
; Interface serial sport 1, 2, 3, or 4 are valid
SPORT = 1
;
; Receive data polarity : 0 = normal 1 = invert
; The polatity is depending on the transmitted signal
RCVPOLARITY = 1
;
The polarity can be setup using the Software, as shown above, or using the hardware with the jumper "DET inv".
Normal
+--------------------+
| ooooo IIIII:I::I + |
| ooooo :::::II::: - |
+--------------------+
+--------------------+
| ooooo I:III:I::I + |
| ooooo :I:::II::: - |
+--------------------+
Some transmitters are using normal and some are using inverted polarity, so check both to find out the correct setting.
Start PocFlex under DOS or under Windows in a fullscreen window.
The activity symbol in the upper left corner should start turning clockwise. (| / - \ | ...). At a signal/noise change, the turning speed should also change.
PocFlex on Win98 in a DOS fullscreen window
After this setup, just follow the instructions from the software manual.
PD 2.05
PD is working only on PURE DOS, not under Windows in a DOS Window.
Edit first the PD.INI file, to setup the software.
# Initialisation file for POCSAG Decoder
[general]
# select the COM port - 1,2,3 or 4
comport=1
# select the pin used for input - cts or dsr
# use cts for standard PD interface, dsr for "Hamcomm" type interface
# use dsr for Optoelectronics Optolinx
# Chose here the data line you have chosen with the MAKInterface Pro jumpers
input=dsr
# select the bit rate - 512, 1200, 2400 or auto
bitrate=auto
The activity Symbol in the bottom right corner schould start turning clockwise. (| / - \ | ...). At a signal/noise change, the turning speed schould also change.
PD under DOS
WinFlex
Chose in the hardware setup menu the serial port and the "2 Level FSK" Interface, NOT the "4 Level FSK"
WinFlex auf Win98
The polarity can be setup using the software or using the hardware with the jumper "DET inv".
Normal
+--------------------+
| ooooo IIIII:I::I + |
| ooooo :::::II::: - |

| ooooo I:III:I::I + |
| ooooo :I:::II::: - |

There are several WinFlex versions. The version 1.00 is written for Win95 and is working excelent on Win95. All other versions are recompiled from other authors. In some ZIP archives a SLICER.VXD for Win98 is also included. But please note that in some zip files the slicer.vxd for Win98 is recompiled with a wrong ddk and is not working propperly.
Winflex is also using other system dll files that can be problem sources. So for example on one PC (with Win98) with a relative clean installation, WinFlex is working without problems. But on an other PC (also Win98) where a lot of software has been installed/deinstalled, WinFlex will not work. In such a case, we do recommend to rename the file c:\windows\system\serial.vxd into c:\windows\system\serial.old.
