SCOM-100, User guide 8

2. Wiring

SCOM-100 is a simple device, not requiring special

technical background for configuration and operation.

However an electrical technician should undertake the

installation of the device.

2.1 Power supply

Power supply requirements are:

SCOM-100-12: 12VDC +/-15%

SCOM-100-24: 24VDC +/-15%

A low ripple power supply output is recommended.

Output voltage stabilization is not required.

See section 9.3.1 for details.

SCOM-100, User guide 9

2.2. Digital inputs

SCOM-100 has 4 built in digital inputs, which can be

expanded by the DIO-42 expansion modules. The digital

inputs are wired by means of screw terminals.

The digital inputs can be driven either by switches or

transistors (open collector stages). Transducers with

push-pull output are also applicable.

Note: Output voltages higher than +5V or negative

voltages (lower than GND) will be clamped

from the comparator input protection zener.

The impedance of the input circuit is, in this

case, 4.7K. An external transducer with 24V

output must be capable of driving a current of

5 mA.

SCOM-100, User guide 10

2.3 Digital outputs

SCOM-100 has 4 built in digital outputs, which can be

expanded by the DIO-42 expansion modules. The digital

outputs are wired by means of screw terminals. Each

output has a normally open contact power relay.

Voltage Current Mode

250VAC 10A AC1

250VAC 1A AC2,3

150VDC 0.5A DC

It is recommended to use external power relays to drive

inductive or capacitive loads demanding more than 0.5A.

SCOM-100, User guide 11

2.4 Analog inputs

SCOM-100 has 2 built in analog inputs (AI1, AI2). A1 is

designed for voltage input and A2 for current input.

2.4.1 Analog input 1

Analog input 1 is a voltage input with two wiring options.

Wiring option: A1A

The input voltage range for this wiring option is 0-1VDC.

The input resistance is 2K. The input voltage range is

converted internally to a digital raw range of 0-4095.

The circuit displayed on the left side of the page uses a

monolithic semiconductor sensor (AD592) for

temperature measurement. This sensor acts as a high

impedance temperature dependent current source of

1µA/K. The nominal current output is 298µA at 25°C. The

voltage drop on the analog input resistor (2K) is 496mV

at -25°C and 756mV at 105°C. The SCOM-100 power

supply (Vcc) can be used for the sensor’s excitation.

SCOM-100, User guide 12

The circuit displayed on the center uses an external

shunt resistor (~51.3 Ω) wired parallel to the input in

order to measure current signals (e.g. 0-20/4-20mA).

The circuit displayed on the right side of the page uses

an external resistor (Rx) to measure DC voltage (Vx). Rx

and Rin (2K) form a voltage divider. The following table

illustrates the applicable resistor Rx values for different

DC voltages:

Vx Rx Vin

0..1V 0 0 -1V

0..5V 8K, 1/4W 0 -1V

0..30V 58K, 1/4W 0 -1V

0..60V 118K, 1/4W 0 -1V

0..100V 198K, 1/4W 0 -1V

Note: In case of low voltage measurements, use short

and shielded wiring to avoid 50Hz (60Hz) line noise

inteference.

SCOM-100, User guide 13

Wiring option: A1B

Wiring option A1B is designed for 0..10VDC signal input

through an internal 18K & 2K voltage divider. The input

resistance is 20K.

SCOM-100, User guide 14

2.4.2 Analog input 2

Analog input 2 is designed as a current input.

It can be used in conjunction with industry standard

current loop transducers & sensors. Input impedance is

50Ω. The 0-20mA input is converted internally to a digital

raw range of 0-4095.

Note: Applying a voltage source to the current input AI2

may damage the internal 50Ω input resistor and

respectively the entire input circuit.

SCOM-100, User guide 15

2.5 I/O expansion power supply

SCOM-100 has two ways to provide power supply for the

I/O expansion units.

Bridge Vcc to Vex on the main SCOM-100 unit to power

a limited number of I/O expansion units (up to 4), as

shown below. (Power is then wired through the 6th pin on

to the modular I/O expansion connector).

If the number of expansion modules is more than 4, an

external power supply source must be connected to the

power connector screw terminals of each expansion

module, as shown below, and the Vcc to Vex on the main

SCOM-100 unit must not be bridged.

SCOM-100, User guide 16

Note: The Vex pin must not be connected when an

external power source is connected on the

expansion modules because the main SCO-100 unit

will be damaged.

SCOM-100, User guide 17

2.6 GSM antenna

An external GSM antenna should be used for locations

with weak signal strength. SCOM-100 utilizes an SMA

plug connector to connect a GSM antenna.

The GSM antenna must be of appropriate frequency to

cover the frequency band of your GSM provider’s

network.

2.7 Microphone

A two-pin connector is provided to connect an electret

type microphone.

SCOM-100, User guide 18

3. Getting started

3.1 Preparing a SIM card

Before installing the SIM card, use your phone to:

1. Clear the PIN code (no PIN needed).

2. Enter your name and phone number in the first

place of the phonebook directory of the SIM card.

Note: You can alternatively power up the unit without a

SIM card and set the PIN number using a terminal

program on a PC, or you can set a PIN in later

configuration stages.

3.2 Installing the SIM card

Note: Always remove or install the SIM card, having the

unit powered down!

Slide the card tray out by pressing the cardholder’s

button with a spiky object such as a pencil or screwdriver.

SCOM-100, User guide 19

Insert the card into the tray and slide the tray with the

card faced down into the cardholder.

3.3 First power up & factory settings

Power up the unit and hold the startup button pressed

until the ready LED starts blinking rapidly.

The unit executes the startup procedure setting all

parameters to the factory defaults, reads the SIM card’s

phonebook entry, enters the RUN (Control) mode and

sends a HELLO SMS message to the mobile phone

number that was found in the SIM phonebook entry.

LED indication states are:

1. READY LED will switch on indicating the successful

reading of the SIM card’s phonebook entry.

2. STATUS LED will switch on indicating the RUN

(Control) mode.

3. NETWORK LED will be blinking to state successful

connection to the GSM provider’s network.

SCOM-100, User guide 20

4. Device operation

4.1 SMS commands

The SCOM-100 unit accepts text SMS commands to

configure operational parameters, control the unit’s

operation modes, and control the unit’s outputs. Several

commands can be packed in one SMS message.

An SMS command has the following structure:

XXXX,A..A,..,..,Z..Z

XXXX: Command identification number 0000-

9999

A..A, Z..Z: Command parameters

The comma character (‘,’) is used as a separator in the

command structure. The semicolon character (‘;’) is used

to separate more than one commands packed in a single

SMS.

4.2 Naming the unit

You can specify a unit name for identification purposes.

The unit name will be used in several device’s SMS

transmissions and responses. The command to name the

unit is:

0300,My SCOM-100

0300: Command ID

My SCOM-100: Device name

Use your mobile phone to edit an SMS containing the

above command. Type in the characters without any
