J8A and J8B Jumpers

RS/OC & RS/RF Jumpers

B1/B2 Jumpers

The ASELPRO has two large chips installed labeled
MAX306CPI. Both jumpers J8A and J8B should be
installed when using this chipset.

RS/OC Jumper:
Install on the left side as shown in the photo above for
normal RS-232 communications. Install to the right side
when using multiple controllers attached to a single
serial port using 2-Way communications to each device
(the RSB Serial Booster will be required for proper
operation).

The B1/B2 jumpers set the baud rate. These jumpers
are read only when power is first applied to the controller. Changing this jumper while power is applied will
have no effect until the next power-up cycle. For your
convenience, a small map is printed on the circuit board
that shows the jumper setting for the various baud rates.
Set the jumpers in accordance with the map printed on
the controller. The default setting of 9600 baud is
shown in the photo above. This controller supports
2400, 9600, 19.2K, and 38.4K baud.

The 8S2SPRO has two large chips installed labeled
MAX307CPI. Both jumpers J8A and J8B should be
removed when using this chipset.

Default Jumper Settings
The jumper settings shown in the photo above represent
the default jumper settings. This sets communication to
9600 baud, 8 data bits, 1 stop bit, no parity.

RS/RF Jumper:
Install on the left side as shown in the photo above for
normal RS-232 communications. Install to the right side
when using the RF receiver option for remote communications. The RF receiver option is scheduled for
release in 2005. A firmware upgrade will be required for
remote control applications. This jumper is read only
when power is first applied to the controller. Changing
this jumper while power is applied will have no effect
until the next power-up cycle.

The RS-232 Data Input (above) connects to the RS-232 Output on your
computer. The RS-232 Output shown
above connects to the RS-232 Input on
your computer. The RS-232 Data
Output line is optional, and is only
required for 2-way communications.

QS12 Quick Start Kit
The QS12 is attached to the ASELPRO/8S2SPRO as shown in the photo above.
The QS12 has 5 prongs that extend out the side. These prongs are secured
using the terminal block screws. This configuration should be considered
temporary for the purposes of initial testing, wires should be connected between
the QS12 and the ASELPRO/8S2SPRO for a more permanent installation.

ASELPRO Operational Description

RCA Phono Connector Varieties

The ASELPRO has 16 inputs and 2 outputs. Any input can be routed to any
output under computer control. Two output ports, Output A and Output B,
each have two connectors. The red and white connectors on output A are
electrically tied together. Output B is configured the same way as output port
A. This is the most popular of the two controller varieties.

The photo below shows an ASELPRO/8S2SPRO with JALCO RCA phono
connectors installed. We may be required to use connectors from two other
suppliers, which are similar in form and function, to the JALCO brand shown
below. The mechanical characteristics may vary slightly between manufacturers. We purchase our connectors in large quantities to help stabilize this
product. JALCO brand connectors are slightly different than other varieties of
connectors. Depending on the brand of connectors used, you may need to
make provisions for future software changes. The JALCO brand connectors,
by default, MAY place inputs 1-8 on the lower row of an ASELPRO, inputs 916 will be on the upper row. This is easily compensated for in software. We
have also made some provisions to swap the connector map to the correct
position using the MAP command in version 4.0 of the ASELPRO firmware.
The 8S2SPRO has the same side effect, but it is not noticeable because there
are only 8 inputs switched in pairs. For these controllers, the MAP setting will
not appear to have no effect and the connector map will never appear incorrect. Please review the MAP function later in this manual. Note that the MAP
command is ONLY supported by Version 4.0 firmware and later, which began
shipping November 8th, 2004.

8S2SPRO Operational Description
The 8S2SPRO has 8 stereo inputs and 2 stereo outputs. Any stereo input can be routed to any stereo output under computer control.
Two output ports, Output A and Output B, each have two connectors. Signal cannot cross the colors boundaries of these connectors. Meaning, signals applied to the red connectors are switched to
red connector outputs ONLY. Signals applied to the white connectors are switched to white connector outputs ONLY. Red and White
signals cannot be crossed under software control. This devices is
ideally suited for stereo audio switching operations.

Electrical Notice:
Switching Characteristics
Approximately 30 MHz Signal Bandwidth with True Bipolar Signal Switching
+/-5VDC. Capable of switching most analog signals. Ideally suited for many
audio, video, and sensor signal switching. This controller introduces a 120
Ohm loss in signal between input and output. Signals can be reversed, inputs
may be used as outputs and outputs may be used as inputs for true bidirectional signal switching. Maximum theoretical switching speed at 38.4K
baud is 1,280 switches per second.

The ring on the outside of each connector is grounded. All grounds are tied
together, including RS-232 ground, power supply ground, and signal ground.
The center of each connector is switched under software control.

Communication Parameters:
User-Selected Baud Rate, 8 Data Bits, 1 Stop Bit, and No Parity.

Multiple Controllers, One Serial Port: Two-Way & One-Way Hybrid Communication
Multiple NCD Devices can be connected to a single serial port
and controlled individually. This example shows an R16 and
an R32 connected to a single serial port. This example can be
applied to any NCD device with a 5-Position terminal block
connector, including the ASELPRO/8S2SPRO . The NCD
E3C network allows you to mix different NCD devices on a single serial port.
Before using this wiring configuration, each device must be
programmed with a unique device number (See E3C Commands for each individual controller for programming details).
Once a device number has been stored into each controller
this wiring configuration may be used to control up to 256 different relay boards or other NCD devices in any combination.
This wiring configuration only allows 2-way communication
with the R32. Relay status information cannot be read from
the R16.
When all boards are first powered up, all devices will respond
to incoming commands. Use E3C Command 252 to speak to
one device at a time. Send 252, 0, any subsequent commands should be for the R32, Device 0. Send 252, 1, any
subsequent commands should be for the R16, Device 1.
This E3C Command 252 is useful when mixing different types
of controllers on a single serial port.

Multiple Device Control: Quick Example
Step 1: Store a Device Number from 0 to 255 into
Each Controller. Example Shows Device 0 and 1.
Step 2: Route Commands to Device 0 Only by Sending the Following Commands:

Multiple Controllers: Two-Way Communication
Many NCD Devices support two-way communication using
the RSB serial booster. Jumpers must be set on all networked devices for Open Collector data transmission. See
the appropriate manual for each controller. This is ONLY
required when using the RSB serial booster. The RSB serial
booster should be used when controlling several devices
over long distances (has been tested in excess of 500 feet).
Actual reliability over long distances depends greatly on baud
rate and type of wire used. Experimentation will be required.
Always start at the lowest baud rate and work your way up.
A unique device number should be programmed into each
device prior to using this example.

Sending Commands to NCD Controllers
Most NCD devices are capable of sending and receiving data
via RS-232 serial communications. NCD products are compatible with just about any computer or microcontroller ever produced, including the Macintosh, Amiga, Basic Stamp, and of
course, Windows & DOS based machines.
Regardless of the system you are using, you will need access
to a programming language that supports program control of
the serial port on your system.
A terminal program is not suitable for controlling NCD devices.
Commands should be sent using ASCII character codes 0-255
rather than ASCII characters (A, B, C etc.). See “ASCII Codes
vs. Characters” on this page.
Most systems require you to open the appropriate serial port
(COM port) prior to sending or receiving data.
Because there are so many different ways to send and receive
data from various languages on various platforms, we will provide generic instructions that can be easily converted to your
favorite language.
For example, if this manual says “Send ASCII 254”, the user
will need to translate this instruction into a command that is capable of sending ASCII character code 254.
To Send ASCII 254 from Visual Basic, you will use the following
line:
MSComm1.Output = Chr$(254)
In Qbasic, you can send ASCII 254 using the following line of
code:
Print #1, Chr$(254);
Note that sending ASCII character code 254 is NOT the same
as sending ASCII characters 2, 5, and 4 from a terminal program. Typing 2, 5, and 4 on the keyboard will transmit three
ASCII character codes.
In your program, you may want to ask an NCD device for the
status informaion, just to confirm a command was received and
processed. If so, your programming language will support commands for reading data from the serial port.
For your convenience, we have provided several programming
examples in Visual Basic 6. These examples should greatly
speed development time. You may want to visit www.
controleverything.com for the latest software and programming examples.
Programming examples are much more extensive for Visual
Basic 6 users than for any other programming language. If you
are not a VB programmer, you may consider looking at the VB6
source code, as it is easily translated into other popular languages.
Regardless of your programming background, the provided Visual Basic 6 source code is very easy to understand and will likely resolve any communication questions
you may have. VB6 programming examples may be
viewed in any text editor.

ASCII Codes vs. Characters
The differences between ASCII codes and ASCII characters
tend to generate a lot of confusion among first-time RS-232
programmers. It is important to understand that a computer
only works with numbers. With regard to RS-232 data, the
computer is only capable of sending and receiving numbers
from 0 to 255.
What confuses people is the simple idea that the numbers 0 to
255 are assigned letters. For instance, the number 65 represents the letter A. The number 66 represents the letter B.
Every character (including numbers and punctuation) is assigned a numeric value. This standard of assignments is called
ASCII, and is a universal standard adopted by all computers
with an RS-232 serial port.
ASCII characters codes can be clearly defined as numbers
from 0 to 255.
ASCII characters however are best defined as letters, A, B, C,
D, as well as punctuation, !@#$%, and even the numbers 0-9.
Virtually all programming languages permit you to send ASCII
in the form of letters or numbers. If you wanted to send the
word “Hello” out the serial port, it is much easier to send the
letters H, e, l, l, and o than it is to send the ASCII character
codes that represent each letter.
For the purposes of controlling NCD devices however, it is
much easier to build a numeric command set. Especially when
communicating to devices where you want to speak to lots of
outputs (which are numbered), inputs (which are also numbered), or control specific devices using their device number
(from 0 to 255).
Put simply, it is easier to control NCD devices using ASCII
character codes 0 to 255 than it is to use ASCII characters A,
B, C, D, etc.
Because terminal programs are ASCII character based, it may
be difficult to generate the proper series of keystrokes that
would be necessary to activate a particular function. Therefore,
they are not suitable for controlling NCD devices. In a real
world control application, a terminal program would not likely be
used to control NCD devices anyway. Therefore, a programming language that supports the transmission and reception of
ASCII character codes 0 to 255 is highly recommended.

The E3C Command Set: Software Control of Multiple NCD Devices
The E3C command set allows you to control up to 256 NCD
devices from a single serial port. It is OK to mix different types
of devices, as long as the devices are E3C compliant. Most
NCD devices support the full set of E3C commands, plus a set
of extended commands for storing and recalling the device
number.
How does E3C Work?
First of all, each device must be assigned a device number
from 0 to 255. This device number must be programmed using
the “Store Device Number” command shown below.
E3C stands for Enabled 3-Wire Communication. Put simply,
when you first power up your computer and all the devices attached to the serial port, all devices will respond to your commands.
Using the E3C command set, you can specify which devices
will listen and which devices will ignore your commands. Note
that E3C commands are never ignored by any device, regardless of the commands you send to the controller.
The number to the left of each command indicates the ASCII
character code that must be sent to issue the command. All
commands must be preceded with ASCII character code 254 to
place the device in command mode. See examples at right.

The E3C Command Set
248 Enable All Devices:
Tells all devices to respond to your commands.
249 Disable All Devices:
Tells all devices to ignore your commands.
250 Enable a Selected Device:
Tells a specific device to listen to your commands.
251 Disable Selected Device:
Tells a specific device to ignore your commands.
252 Enable Selected Device Only:
Tells a specific device to listen to your commands, all other devices will ignore your commands.
253 Disable a Selected Device Only:
Tells a specific device to ignore your commands, all others will
listen.

Extended E3C Commands
This device supports two additional E3C commands which
should only be used when a single device is attached to your
serial port. Extended commands will report back to the computer.
255 Store Device Number:
Stores the device number into the controller. The device number takes effect immediately. The enabled/disabled status of
the device is unchanged.
247 Recall Device Number:
Allows you to read the stored device number from the controller.

E3C Visual Basic Programming Examples
The E3C command set is easily used from any programming language that supports serial communication. The
following Visual Basic 6 Example source code demonstrates subroutines that can be used to control which devices will listen and which devices will ignore your commands.

Sample Code: The E3C Command Set
Public Sub EnableAllDevices()
'Enable All E3C Devices

The ASELPRO/8S2SPRO Command Set
The ASELPRO/8S2SPRO supports a comprehensive command set,
used to input/output channel selection, set operation modes, and store
and recall device information. Most users will not use many of the functions built into this controller. The best way to familiarize yourself with
the capabilities of this devices is to carefully read through the command
set in this section. The “plain English” examples provide a quick, easy
to understand definition of what each command does.
The number to the left of each command indicates the ASCII character
code that must be sent to issue the command. All commands must be
preceded with ASCII character code 254 to place the device in command mode. See examples at right.

Switching Commands
1 Set Output Channel A to Desired Input

This command connects an input to output channel A. This command
has one parameter, indicating the desired input channel. Valid input
channels are 1-16 for the ASELPRO or 1-8 for the 8S2SPRO.

2 Set Output Channel B to Desired Input

This command connects an input to output channel B. This command
has one parameter, indicating the desired input channel. Valid input
channels are 1-16 for the ASELPRO or 1-8 for the 8S2SPRO.

3 Set Output Channel A and B Simultaneously (Friendly)

This command routes two inputs to each of the two outputs. This command has two parameters, indicating the desired inputs for output
channels A and B. Valid input channel parameters are 1-16 for the
ASELPRO or 1-8 for the 8S2SPRO.

4 Set Output Channel 1 and 2 Simultaneously (Fast)
Version 5.0+ Firmware ONLY

This command routes two inputs to each of the two outputs. This command has one 8-bit parameter. The lower four bits of this parameter
set the input channel to be routed to Output A, the upper four bits of this
parameter set the input channel to be routed to Output B. Experience
with the binary numbering system is required to make use of this command. This allows for fastest possible switching routes with minimal
serial communications.

10 Get E3C Device Number
This command reports back the currently stored E3C device
number. Identical to E3C command 247.
11 Report the Input Currently Routed to Output A
This command reports a Value of 1-16 indicating the current
input channel that is currently routed to Output A. Only the
lower 8 bits of the returned value are valid for 8S2SPRO users.
12 Report the Input Currently Routed to Output B
This command reports a Value of 1-16 indicating the current
input channel that is currently routed to Output B. Only the
lower 8 bits of the returned value are valid for 8S2SPRO users.
13 Store Current Route Pattern as Powerup Default
Stores Current Input Channel Selection for Output Channels A
and B in Non-Volatile Memory. Every time power is applied,
inputs and outputs will automatically switch to the user-defined
states of each output channel. Simply use other switching commands to setup the input route. Then issue this command to
store the route pattern.
14 Report Default Powerup Route Pattern
This command reports back two values, indicating the input
route for Channel A and Channel B (respectively) when power
is first applied to the controller.

Visual Basic Programming Examples
Many Visual Basic 6 programming examples are provided in the following pages to assist in the development of software for controlling the
ASELPRO/8S2SPRO. Additional source code can be found on our

The ASELPRO/8S2SPRO Command Set
Mapping Commands

Sample Code: Mapping Commands

The Mapping commands only apply to the ASELPRO, the 8S2S is not
affected by the use of these commands. Because we have three different sources for RCA phono connectors, two of which have slightly different wiring configurations, it may become necessary to re-map the
inputs. When using connectors manufactured by JALCO (white), the
Mapping value should be set to 1. All other connectors (black ones as
well as some varieties of white connectors), the mapping value should
be set to 0. The purpose of the Mapping commands is to swap the
inputs. When using JALCO phono connectors, inputs 1-8 are on the
lower row instead of the intended top row. The Mapping commands will
move inputs 1-8 to the top row and the bottom row will be reserved for
inputs 9-16 (which is our intended operation). If at any time, you experience input one on the lower row, change the Map setting to move
the inputs back to the top row of connectors. Mapping commands are
non-volatile and will be kept in memory until changed, even if power is
removed from the controller. Mapping commands only work with Version 4 firmware or later. If you do not have Version 4 firmware and you
need to remap the inputs, use the VB code below titled “Mapping Without V4 Firmware”.

15 Set Mapping Value
Version 4.0+ firmware only

Sample Code: Mapping Without V4 Firmware

This command stores a MAP Value used to swap the Upper and Lower
Rows of Inputs on the ASELPRO. This command has one Parameter
with a Valid Value of 0 or 1. A value of 0 Sets the inputs to the standard map. A value of 1 swaps upper and lower eight rows of inputs
most commonly used with JALCO connectors. This command works
with Version 4.0 firmware and later ONLY.

16 Get Mapping Value
Version 4.0+ firmware only

This command reads the current Map setting and returns a 0 or a 1.

Version Command
99 Get Version
Version 4.0+ firmware only

This command reads the current version of firmware and returns a
value of 4 or greater depending on the current version of firmware installed. Version 5 firmware supports improved switching efficiency by
reducing the number of bytes required for switching. Version 5 (upon
release) will support RF wireless control of this device.

Future Upgrade Plans
One issue that remains to be addressed in the ASELPRO/8S2SPRO is
a minor bug whereby this device may not report ASCII character 0. We
are researching the cause of this problem and hope to offer an upgrade
for this in version 5 firmware. This problem only applies to reading E3C
device number 0 or reading the MAP setting when set to 0, the device
may not reply with any data. This does not affect the reading of input
channels, these functions report back values from 1 to 16.
We also hope to have RF communications implemented in Version 5
firmware. At the time of writing, we are developing our first wireless
communication processors that allow you to control up to 1.7 Million
NCD devices under wireless control. Full wireless implementation protocols will likely be introduced in version 5 firmware.

Use the following routine to Swap the Upper and Lower set of Inputs
Without Upgrading the ASELPRO firmware. We only shipped approximately
70 boards where this section of the manual will apply.
A Normal Switching routine looks like this:
Public Sub ChannelA(In)
MSComm1.Output = Chr$(254)
MSComm1.Output = Chr$(1)
MSComm1.Output = Chr$(In)
End Sub

'Channel Select for Output A
'Enter Command Mode
'Set Channel A Command
'to Input (1-16)

Public Sub ChannelB(In)
MSComm1.Output = Chr$(254)
MSComm1.Output = Chr$(2)
MSComm1.Output = Chr$(In)
End Sub

'Channel Select for Output B
'Enter Command Mode
'Set Channel B Command
'to Input (1-16)

It may be necessary to swap the Upper and Lower set of connectors to
ensure Input 1 is on the top row (this only applies to boards that
have shipped that use white JALCO RCA phono jacks). In this case, use
these commands for switching:
Public Sub ChannelA(In)
If In < 9 then
MSComm1.Output =
MSComm1.Output =
MSComm1.Output =
else
MSComm1.Output =
MSComm1.Output =
MSComm1.Output =
endif
End Sub
Public Sub ChannelA(In)
If In < 9 then
MSComm1.Output =
MSComm1.Output =
MSComm1.Output =
else
MSComm1.Output =
MSComm1.Output =
MSComm1.Output =
endif
