est version of our popular

analog signal switchers. Ide-

ally suited for audio and video

switching, as well as many

analog switching applications,

these new devices now sup-

port 2-Way communications,

3 Status LEDs, and communi-

cations rates up to 38.4K

baud. The ASELPRO has 16

analog inputs and 2 analog outputs. Any analog input

can be routed to any analog output under computer

control. The 8S2SPRO is often used in switching of

stereo audio signals. The 8S2SPRO has 8 stereo in-

puts and 2 stereo outputs. Any stereo input can be

routed to any stereo output under computer control.

Left and Right audio channels are switched simultane-

ously. Alternatively, the inputs of the 8S2S can be

used for one audio channel and one video channel or,

the inputs can be used for video or other analog sig-

nals. Input to output resistance is about 120 Ohms.

ma OR GREATER.

3) USE A SUPPLY RATED FOR MORE AMPERAGE

WHEN POWERING MULTIPLE BOARDS.

4) DC POWER SHOULD NEVER TRAVEL GREATER

THAN 20 FEET. A SEPARATE POWER SUPPLY

SHOULD BE USED FOR EACH CONTROLLER IF

CONTROLLERS ARE NOT LOCATED WITHIN 20

FEET OF EACH OTHER.

POWER SUPPLY REQUIREMENTS Status LEDs:

Data In LED:

This LED is connected to the RS-232 input path. This LED flashes any time a data voltage appears on the

RS-232 input line. If this LED does not flash, the controller is not receiving data.

E3C LED:

This LED is used to display the E3C status of the board. By default, this LED is lit, meaning it is ready to

process RS-232 serial commands. This LED turns off when an E3C command is issued to direct data to a

different E3C device. This LED must be lit for proper processing of switching commands. Use the E3C

command set to enable/disable this device. This LED will light when the device is enabled.

Command LED:

This LED flashes with the Data In LED when commands are being processed. Both Data In and Com-

mand LEDs appear to do the exact same thing under normal operation However, this LED is driven by the

microprocessor and ONLY lights when a valid command sequence is executed. If the Data In LED lights,

and the Command LED does not light at the same time, the device may not be enabled (see E3C LED

above). If this LED does not light in sync with the DATA IN LED, check to make sure the baud rate of the

controller matches the baud rate of your software.

J8A and J8B Jumpers

The ASELPRO has two large chips installed labeled

MAX306CPI. Both jumpers J8A and J8B should be

installed when using this chipset.

The 8S2SPRO has two large chips installed labeled

MAX307CPI. Both jumpers J8A and J8B should be

removed when using this chipset.

RS/OC & RS/RF Jumpers

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).

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 communi-

cations. 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.

B1/B2 Jumpers

The B1/B2 jumpers set the baud rate. These jumpers

are read only when power is first applied to the control-

ler. 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.

IMPORTANT NOTE:

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.

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.

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 bi-

directional signal switching. Maximum theoretical switching speed at 38.4K

baud is 1,280 switches per second.

ASELPRO Operational Description

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.

8S2SPRO Operational Description

The 8S2SPRO has 8 stereo inputs and 2 stereo outputs. Any ste-

reo input can be routed to any stereo output under computer control.

Two output ports, Output A and Output B, each have two connec-

tors. Signal cannot cross the colors boundaries of these connec-

tors. Meaning, signals applied to the red connectors are switched to

red connector outputs ONLY. Signals applied to the white connec-

tors 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:

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.

RCA Phono Connector 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 manufactur-

ers. 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 9-

16 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 incor-

rect. 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.

Two-Way Communication:

The ASELPRO/8S2SPRO support two-way communi-

cation for reporting the signal routing status back to the

host computer.

The ASELPRO/8S2SPRO should be connected as

shown below when using this device for the first time.

Even if you plan to connect several ASEL-

PRO/8S2SPRO controllers to a single serial port, this

wiring diagram must first be used to program the de-

vice number into the controller.

The ASELPRO/8S2SPRO Visual Basic Example Pro-

gram expects this wiring configuration.

The ASELPRO/8S2SPRO can be connected to a com-

puter or microcontroller using as little as two wires. Mem-

ory Storage commands may take a little longer to process

than others, so it may be necessary to add short delays

in your program to allow time for execution of these com-

mands. It is not possible to request data from the ASEL-

PRO/8S2SPRO using this wiring configuration.

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 sin-

gle serial port.

Before using this wiring configuration, each device must be

programmed with a unique device number (See E3C Com-

mands 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 dif-

ferent 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 com-

mands 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 Controllers: Two-Way Communication

Many NCD Devices support two-way communication using

the RSB serial booster. Jumpers must be set on all net-

worked 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.

Limitations:

1) The RSB Serial Booster is NOT Compatible with Baud

Rates above 38.4K Baud.

2) It is estimated that a single serial booster can control

256 Relay controllers. This has not been tested, and

may be subject to other baud rate or distance limita-

tions. Please contact us if you have application prob-

lems with this configuration.

Connect up to 256 de-

vices on a Single Serial

Port. Each R16 MUST

be Programmed with a

Unique Device Number.

Jumpers MUST be

Set between the

Sending Commands to NCD Controllers

Most NCD devices are capable of sending and receiving data

via RS-232 serial communications. NCD products are compati-

ble with just about any computer or microcontroller ever pro-

duced, 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 pro-

vide 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 ca-

pable 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 pro-

gram. 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 com-

mands 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 program-

ming 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 lan-

guages.

Regardless of your programming background, the pro-

vided Visual Basic 6 source code is very easy to under-

stand and will likely resolve any communication questions

you may have. VB6 programming examples may be

viewed in any text editor.

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 repre-

sents the letter A. The number 66 represents the letter B.

Every character (including numbers and punctuation) is as-

signed 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 num-

bered), 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 program-

ming language that supports the transmission and reception of

ASCII character codes 0 to 255 is highly recommended.

ASCII Codes vs. Characters

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 at-

tached to the serial port, all devices will respond to your com-

mands.

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, regard-

less 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.

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 de-

vices will ignore your commands.

253 Disable a Selected Device Only:

Tells a specific device to ignore your commands, all others will

listen.

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 com-

puter.

255 Store Device Number:

Stores the device number into the controller. The device num-

ber 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 control-

ler.

The E3C command set is easily used from any program-

ming language that supports serial communication. The

following Visual Basic 6 Example source code demon-

strates subroutines that can be used to control which de-

vices will listen and which devices will ignore your com-

mands.

Sample Code: The E3C Command Set

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 func-

tions 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 com-

mand mode. See examples at right.

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 com-

mand 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 com-

mand 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 com-

mand. 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 com-

mands 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.

Many Visual Basic 6 programming examples are provided in the follow-

ing pages to assist in the development of software for controlling the

ASELPRO/8S2SPRO. Additional source code can be found on our

Switching Commands

Visual Basic Programming Examples

Sample Code: Switching Commands

Sample Code: Reading Data from Controller

The ASELPRO/8S2SPRO Command Set

The Mapping commands only apply to the ASELPRO, the 8S2S is not

affected by the use of these commands. Because we have three differ-

ent sources for RCA phono connectors, two of which have slightly dif-

ferent 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 ex-

perience 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 Ver-

sion 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 With-

out V4 Firmware”.

15 Set Mapping Value

Version 4.0+ firmware only

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 stan-

dard 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.

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 in-

stalled. 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.

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 pro-

tocols 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) 'Channel Select for Output A

MSComm1.Output = Chr$(254) 'Enter Command Mode

MSComm1.Output = Chr$(1) 'Set Channel A Command

MSComm1.Output = Chr$(In) 'to Input (1-16)

End Sub

Public Sub ChannelB(In) 'Channel Select for Output B

MSComm1.Output = Chr$(254) 'Enter Command Mode

MSComm1.Output = Chr$(2) 'Set Channel B Command

MSComm1.Output = Chr$(In) 'to Input (1-16)

End Sub

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) 'Channel Select for Output A

If In < 9 then

MSComm1.Output = Chr$(254) 'Enter Command Mode

MSComm1.Output = Chr$(1) 'Set Channel A Command

MSComm1.Output = Chr$(In+8) 'Move Inputs to Upper Row

else

MSComm1.Output = Chr$(254) 'Enter Command Mode

MSComm1.Output = Chr$(1) 'Set Channel A Command

MSComm1.Output = Chr$(In-8) 'Move Inputs to Lower Row

endif

End Sub

Public Sub ChannelA(In) 'Channel Select for Output B

If In < 9 then

MSComm1.Output = Chr$(254) 'Enter Command Mode

MSComm1.Output = Chr$(2) 'Set Channel B Command

MSComm1.Output = Chr$(In+8) 'Move Inputs to Upper Row

else

MSComm1.Output = Chr$(254) 'Enter Command Mode

MSComm1.Output = Chr$(2) 'Set Channel B Command

MSComm1.Output = Chr$(In-8) 'Move Inputs to Lower Row

endif

End Sub
