==Parallel Port==
+
When setting chan_usbradio to use a parallel port for I/O you must set a definition for the port address in rpt.conf:
+
+
<pre>
+
iobase=0x378 ; Parallel port address (using for cor/ptt & switches +dh-rbi - 378,278,3bc common Lpt 1,2,3
+
</pre>
+
+
You must then define the parallel port pins used for I/O in usbradio.conf:
+
+
<pre>
+
[usb]
+
pp6=ptt
+
pp11=cor
+
</pre>
+
+
When configuring your usbradio node you '''''MUST''''' ensure that the name of the radio is the same in both rpt.conf and usbradio.conf.
+
+
Node names are in format of ''usb_<nodenumber>''. Where <nodenumber> = the AllStar Link node of your system. ''Note that usb and the node number are separated by an underscore (_) character.''
+
+
Example:<p>
+
Your usbraido.conf file defines your usb radio as '''[usb_1000]'''. Your rpt.conf file would then have:
+
+
<pre>
+
rxchannel = radio/usb_1000
+
</pre>
+
+
If you are reusing the usbradio.conf file from an older installation (i.e., ACID), take special note of the change in naming. chan_usbradio may not work without first making this change to your usbradio.conf file.
