1 Introduction
This document will describe the components of the Compact Reader System ARE i2 / RS 232 and the procedure how to do the first set up of the reader.
The main features of the reader are listed below:
• the antenna is placed inside of the housing
• there are algorithm available to read nearly all 125 kHz-transponders on market
• integrated RS232 Interface with tunable baud rate are up to 19200 Bit/s
• the allowed supply voltage is 9 to 30V DC
• low power consumption of reader < 1.2 Watt
• high reliability for reading and writing within an industrial environment
• compact housing of the reader with multiple ways for mounting
• the cabling concept of the reader is optimised to service demands
• the protection class of the housing is IP65
• there is a set of external antennas available to meet special application demands ( X-tended version)
2 System overview
In the base version all electronic components of the reader are placed inside of a small plastic housing.
By means of the integrated antenna the reader generates an alternating magnetic field, which powers the transponder. Coded signals sent back from the transponder are received and decoded by the reader. The reader is fully controlled by a master with RS 232 data port, while using the integrated serial RS 232 interface of the reader.
There is a version available without the integrated antenna. On this version it is possible to connect an external antenna.

To get the specified reading performance it is necessary to do the installation carefully step by step as it is described in the following Chapters. All the work must be done by well educated people.
3.1 Mounting of the housing
The reader can be mounted to any other mechanic construction. The distance between reader and tran­sponder has to tuned
It is recommended to protect the housing against heavy mechanical interactions and drippy fluids.
Attention!
The side of the housing showing the antenna symbol must not be brought next to a metal surface. This could lead to a significant change of the properties of the antenna circuit, which in turn reduces the reading range considerably.
With the help of the plastic bars, the reader can mounted or screwed on to the most fastening elements without open the housing of the device.
3.2 Grounding of the reader
To get reliable reading results, the reader must be grounded. The connector is placed at the side of the housing (6.35 mm flat contact). To avoid EMV-problems, the cable to ground ought to be very short with low impedance.
Attention!
The topology of the ground wires must be done in the right way (according state of art).
3.2.1 Connecting of the plug
Attention!
Be sure that the grounding of the reader is well done and the power supply is not connected(chapter 3.2). Otherwise the electronic may be destroyed by electrostatic discharge (ESD).

Figure 2: Connecting of the plug
Put on the sealing 2 to the SAB Cab (A).
Plug in the SAB Cab to the connector at the bottom of the reader device (B).
There is only one way to plug in the SAB Cab to the connector rim of the reader.
Fasten the SAB Cab with the help of the screws.

To meet the protection class of IP 65, it’s necessary to apply a turning moment of 0.5 Nm to the screws.
3.3 Connecting of the power supply cable
The reader has to be supplied with 9..30V DC. The maximum output power of the power supply has to be
1.2 Watt. Be sure that you use the right polarity.
3.3.1 Using the pc connection cable ID 70213
Power supply: brown = + 9 .. 30 Volt
white = ground
3.3.2 Using the switchboard cable ID 70212
Power supply: brown = + 9 .. 30 Volt
white = ground
Data interface: green = RXD (readers data input)
yellow = TXD (readers data output)
grey = ground
3.3.3 Using a self assembled connecting cable
Using the following SAB cabs you can assemble your own connecting cable.
ID 70211 SAB cab with 1 PG9 cable pipe
ID 70215 SAB cab with 2 pre-assembled cable pipes
ID 70219 SAB cab without any cable pipe
You can use any shielded five-pole cable. The allowed diameter of the cable must be in the range from ∅3,5 to ∅8mm. For this case, IP 65 is reached.
Attention!
The minimum voltage at the readers input mustn’t be lower then 9V.
The maximum length of the serial RS232 cable is 15m.
3.3.3.1 Assembling of the cable pipe
• Breakthrough the prepared areas at the surface of the SAB Cabs. There are two prepared areas seen
at the SAB Cab: central and at one side of the cab.
• The o-ring (3) has to be assembled proberly to the cable pipe (4) to ensure the protection class IP
65.

Figure 3: Assembling of the cable pipe
• Bring the nut (2) of the cable pipe inside of the SAB Cab (1).
• To fasten the nut please use the right tool (17mm).
3.3.3.2 Mounting of the cable
The cable must be mounted in following steps:
• Remove all inner parts from the cable pipe at the SAB Cab (1) ( nut (5), cable fastener (3), pipe(4)) (see Figure 4)
• Put all the removed parts (nut (5), cable fastener (3), pipe (4),) and the cable pipe of the SAB Cab as well (1 to 4) to the cable.

Figure 4: Mounting for the cable
• Remove the outer isolation of the cable at a length of 6cm .
• Remove the isolation of the wires at a length of 6mm and stick a covering hull to the litz wire.
• Put the cable to the cable pipe. The length of the cable coming out the SAB Cab must long enough to
do all further installation steps in an easy way.
• Stick the pipe (4) into the cable fastener (3).
• Stick the cable fastener (3) into the cable pipe.
• Connect the cables into the right places of the MINI-COMBICON-Connectors (6).
• The pin assignment is shown in the figure below.
• Put the MINI-COMBICON-Connectors into the SAB cab. Look after the color coding.
