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).

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.

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.

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.
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)

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.
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.
