Interface board, power supply, RS-232 cable, and demonstration/test software.
The SIO-1000 interfaces the following signals:
The 8 digital inputs and 8 outputs connect to a 50-pin 0.1" double-row header for easy connection to industry standard 16 channel digital I/O "racks" (mounting boards for opto-isolated modules), typical of Potter and Brumfield 2IO-16 and Gordos PB-16 racks. The SIO-1000 digital inputs 0 through 7 are associated with rack I/O channels 0 through 7, and SIO-1000 digital outputs 0 through 7 are associated with rack I/O channels 8 through 15 respectively.
The following signals connect to screw terminals for quick discrete connection:
P.C. Board assembly has 4 holes available for mounting to enclosure or #6 standoffs.
P.C. Board Dimensions: 5.25 inches by 4.00 inches
Enclosure: Bud Industries CU-387-MB utilibox
Enclosure Dimensions: 5.50L x 4.25W x 1.75D (6.5L including mounting flange)

These specifications are for actual measured voltages at the SIO-1000. Be advised that all unregulated wall pack power supplies produce their rated voltage only at their specified current, and will actually produce a much higher voltage at lower current drains. For example, a 12 volt unregulated supply rated at 800 ma may actually produce 20 volts when connected to the SIO-1000. Use either the wall block power supply provided with the SIO-1000, or a supply rated for 12 volts at 100 ma or less, or one you have measured with a meter and know to be an appropriate voltage.
On-board LED's:
The green power LED (PWR) indicates power applied to SIO-1000. The red overvoltage LED (OV) indicates a voltage over 20 volts internal to the SIO-1000 and that excessive power is being dissipated by the internal voltage regulators.
Power available at the screw terminals:
The +5 volt and +12 volt supplies used on-board the SIO-1000 are made available at discrete screw terminals to allow quick interfacing to certain devices requiring power without having the need to provide separate power supplies. However, the current drawn from these terminals should not exceed 100 milliamperes from either supply.

Analog Output Range:
Jumpers AO0 and AO1 are individual 3 pin jumpers that select the analog output range on each output to be either 0 to 5 volts or 0 to 10 volts depending on which position you place the jumpers, to the top or to the bottom.
AO0 AO1
top position 0-10 top position 0-10 volts
(default) bottom position 0-5 bottom position 0-5 volts
Baud Rate and Character Echo:
Jumpers SEL0, SEL1, SEL2, and SEL3 are arranged in a group of 12 pins that select the baud rate and echo options depending on which position you place the jumpers, to the left or to the right.
The following is a table of jumper arrangements and baud rates available.
baud rate 19.2K 9600 4800 2400 1200 600 300 150

Waveform Output Polarity:
Jumper WO is an individual 3 pin jumper that selects the polarity of the waveform generator output. When placed in the "H" position which is to the left, the transistor will be turned off when waveforms are generated, thereby providing a high-going logic level from the pull-up resistor. When placed in the "L" position which is to the right, the transistor is turned off upon power-up or reset of the SIO-1000, and waveforms will cause it to be turned on. Use this option when connecting devices to the waveform output that you do not wish to draw current on reset, such as a speaker or a relay.
left position H high-going waveform
(default) right position L low-going waveform
Pulse Counter Input Filter:
Jumper CI is an individual 3 pin jumper that selects whether or not a filter capacitor is placed between the pulse counter input and ground. When placed in the "NF" position which is to the left, the capacitor is not connected. Use this option when connecting devices to the pulse counter input that will produce bounce-free ("clean") pulses. When placed in the "F" position which is to the right, the capacitor is connected. Use this option when connecting devices to the pulse counter such as a pushbutton switch which will have a mechanical bounce (producing multiple contact closures) in its contacts. Use of the filter in this case will allow the pulse counter input to recognize each press of the switch as just one count.
(default) left position NF no filter capacitor connected
right position F filter capacitor connected

Commands are followed by a carriage return, and responses are followed by a carriage return/line feed sequence to make testing the unit with a terminal program possible.
Commands not understood by the SIO-1000 or commands sent with an improper or out of range value are responded to with a question mark and a carriage return/line feed sequence.
To verify the correct receipt of data sent from the SIO-1000 in response to a command, the command can be repeated, since responses are very short.
To verify the correct receipt of commands by the SIO-1000, two methods may be used. A jumper selection is provided that causes all characters received to be echoed back to the transmitting device. The echoed characters from a command can be compared one by one to the characters sent, and if any character in a command fails the comparison, an escape character can be sent instead of the final carriage return to reset the software and abort the command. Alternately, since all output commands have a corresponding command that allows reading back the value set with the output command, these separate commands may be used to insure that the value has been properly set.
Values sent and received are in ASCII encoded hexidecimal where:
x can be a value from 0 to 7 hex (0 to 7 decimal)
y can be the value 0 or 1 hex (0 or 1 decimal)
xx or yy can be an 8 bit value from 00 to FF hex (0 to 255 decimal)
xxx can be a 12 bit value from 000 to FFF hex (0 to 4095 decimal)
xxxx or yyyy can be a 16 bit value from 0000 to FFFF hex (0 to 65535 decimal)
<CR> is a carriage return character: 0D hex (13 decimal)
<LF> is the line feed character: 0A hex (10 decimal)
<ESC> is the escape character: 1B hex (27 decimal)

Frequency resolution:
The frequency generated by the waveform generator is a software approximation of the frequency specified in the command. The software in the SIO-1000 calculates the number of periods required to produce the waveform based on the period of the processor clock, which is not an exact multiple of most frequencies desired. This calculation must round off the number of periods used to produce waveforms at certain frequencies, therefore, different frequencies specified with the command might actually generate the same waveform frequency. This effect is even more pronounced at the higher frequencies.
The waveform generator output can be used in three different modes.
1. Frequency generator
2. Pulse width modulation generator
3. Digital output
1. Frequency generator mode:
In the frequency mode, the waveform generated is a 50 percent duty cycle waveform at the frequency specified, which can be anywhere from 15 hertz to 5000 hertz. Frequency accuracy is 1 percent. This waveform can be generated continuously by specifying only the frequency in the command, or if an additional parameter is given, the frequency can be generated only for a specified number of pulses before stopping.
The frequency mode commands are:
Set continuous frequency output
Sent to SIO: Fxxxx<CR>
Range: xxxx = 000F-1388, frequency from 15HZ to 5KHZ, or 0000 to turn off the waveform

Received from SIO: nothing
Processing time: 3.1 ms
Read frequency output set value
Sent to SIO: f<CR>
Range: xxxx = 0000-1388
Received from SIO: fxxxx<CR><LF>
Processing time: 460 us
2. Pulse width modulation generator mode
In the pulse width modulation mode (PWM), the waveform generated is one of 6 different frequencies based on multiples of 100 periods, which provides a duty cycle selectable from 1 to 99 percent at the lower frequency selections. At the higher frequencies the range of possible duty cycles is narrowed due to the short amount of time available for the software to do the necessary work to produce an accurate waveform.
The pulse width modulation (PWM) mode commands are:
Set PWM output
Sent to SIO: Wxyy<CR>
Received from SIO: nothing
Processing time: 480 us
Range: x = frequency selection yy = duty cycle in percent
0 = none (off) 00 = waveform off
1 = nominal 92 01H-63H (1-99D)
2 = nominal 128 01H-63H (1-99D)
3 = nominal 252 01H-63H (1-99D)
4 = nominal 498 01H-63H (1-99D)
5 = nominal 972 02H-62H (2-98D)
6 = nominal 2052 07H-5DH (7-93D)
Read PWM output set valueIn the digital output mode the waveform generator output can be used as an extra digital output which can turn on and off an open collector transistor. (Since a pull-up resistor is included at the collector of the transistor, the on/off commands will be inverted if the output is used as a logic level output.)
The waveform generator transistor output used in digital output mode is turned on and off with single bit commands:
