→Parallel Port Pin Numbers
chan_simpleusb is ideal for smaller computers and those systems that do not need the chan_usbradio driver.

== Notes ==
When configuring your simpleusb radio node you '''''MUST''''' ensure that the name of the radio is the same in both rpt.conf and simpleusb.conf.
When configuring your simpleusb radio node you '''''MUST''''' ensure that the name of the radio is the same in both rpt.conf and simpleusb.conf.
The system looks inside the file SimpleUSB.conf for the match of the node# to be configured (i.e. usb_1234).
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.''
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>
===Example===
Your simpleusb.conf file defines your usb radio as '''[usb_1000]'''. Your rpt.conf file would then have:
Your simpleusb.conf file defines your usb radio as '''[usb_1000]'''. Your rpt.conf file would then have:
<pre>
<syntaxhighlight lang="ini">rxchannel = SimpleUSB/usb_1000</syntaxhighlight>
rxchannel = SimpleUSB/usb_1000
</pre>
If you are reusing the simpleusb.conf file from an older installation (i.e., ACID), take special note of the change in naming. When a exact match is not made, the settings that follow will not be loaded.
=Miscellaneous=
Parallel Port Addressing:
A line is required in your node stanza in RPT.conf to access the parallel port in the software.
<syntaxhighlight lang="ini">iobase=0x378 ; Parallel port address</syntaxhighlight>
Settings are 0x378 = LPT1, 0x278 = LPT2, 0x3bc = LPT3
You can have more than one, but you need to place them in other node stanza's addressed separately.
Note: Some older systems plug and play can have issues addressing these. If so, go to bios setup and address them manually.
This will prevent the system from changing the address.
==Parallel Port Pin Numbers==
'''Additional notes on parallel port pin numbers.'''
When you are looking at the '''pp#''' addressing, the actual hardware pin numbers are in computer natural logical format.<br>
So hardware pin '''''D0''''' on the LPT port is equal to '''''pp1''''' in the software configuration.<br>
"0" is the first number to a computer as seen at the BIOS and/or hardware addressing.<br>
Be sure you are testing/setting/attaching the correct pin number.
Here is a listing of hardware pins and the software setup equivalents:
{| class="wikitable"
! Hardware pin !! Software equivalent
|-
| D0 || pp1
|-
| D1 || pp2
|-
| D2 || pp3
|-
| D3 || pp4
|-
| D4 || pp5
|-
| D5 || pp6
|-
| D6 || pp7
|-
| D7 || pp8
|}
Allstar denoted pins pp9 through pp12 are 'Input pins' listed as 'A#' in the parallel port scheme.
===Special note===
All these pins require 'buffering' by adding a transistor to do the actual switching.
They will not sink much current on their own.
While these port pins vary, most will only sink about 20ma-50ma of current.
In the case of some older radios you might interface, you might need to buffer with a transistor (2n2222 / 3904/3906)
AND/OR a relay actuated by the buffer transistor. Mainly the PTT lines.
The best design is with optically-coupled transistors to prevent voltages and/or rf from running back through this port.
The unused output pins can be applied to switch things at the site. i.e. fan/light/alarm or even switching off other equipment.
It is not advisable to work a relay coil directly with a PP pin.
It is a coil and susceptible to absorbing RF and there is no quicker way to lock a computer up than to bugger this input/output with a stray signal.
If you are reusing the simpleusb.conf file from an older installation (i.e., ACID), take special note of the change in naming. chan_simpleusb may not work without first making this change to your simpleusb.conf file.
===Final Note===
If you think you might be adding a Doug Hall RBI-1 Remote base later, Start populating pins 'above' pp3 reserving the 1st 3 pins.
Check command tables for info, not related to simple_usb.conf.
