1Introduction
This document will describe the components of the AMP 4/8 and the procedure how to do the first
set up of the reader.
The main features of the reader are listed below:
up to 8 antennas connectable
integrated RS232 or USB interface
3 different types of controlling possible (RS232/USB, with the reader ARE i2, with digital in-
puts)
power supply from 9V DC to 30V DC (see chapter 2.3)
compact housing
the protection class of the housing is IP65
2Installation
To ensure a proper function of the AMP 4/8 you have to follow the steps in following chapters. The
installation should be done by trained people.
2.1 Mounting of the housing
The AMP 4/8 can be mounted to any other mechanic construction. It is recommended to protect the
housing against heavy mechanical interactions and drippy fluids.
With the help of the plastic bars, the reader can be mounted or screwed on to the most fastening
elements without open the housing of the device.
2.2 Grounding of the AMP 4/8
The AMP 4/8 should 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.

--------------------------------------------------------------------------------5/20--------------------------------------------------------------------------------
Attention!
The topology of the ground wires must be done in the right way (according state of art).
2.3 Connecting of the plug
Attention!
Be sure that the grounding of the reader is well done and the power supply is not connect-
ed(chapter 3.2). Otherwise the electronic may be destroyed by electrostatic discharge (ESD).
Figure 1: connecting 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.

--------------------------------------------------------------------------------6/20--------------------------------------------------------------------------------
2.4 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.
It is very important to power the AMP with a clean ground (without any electrical interferences).
The best way is, to use the same ground as the reading system.
2.4.1 Using the connecting cable for AMP und ARE i2 (RS232)
Power supply: brown = + 9 .. 30 Volt
white = ground
2.4.2 Using the switchboard cable for AMP (RS232)
Power supply: brown = + 9 .. 30 Volt
white = ground
Interface: green = RXD (Dataout AMP 4/8)
yellow = TXD (Dataout AMP 4/8)

--------------------------------------------------------------------------------7/20--------------------------------------------------------------------------------
2.4.4 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.
2.4.4.1 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.

4Instruction set / structure of the instruction set
4.1 Generall
The command set described below defines the transfer of data on the serial interface.
The commands consist of a command code and optionally of a parameter value. Commands are ter-
minated by the control character <CR> (13h). The control character serves as command line termi-
nator.
Command codes and parameters, that means all letters and numerical values, are principally trans-
mitted as a sequence of ASCII characters (the value 255 (decimal) consequently as 32H, 35H,
35H; the command RST as 52H, 53H, 54H).

--------------------------------------------------------------------------------11/20--------------------------------------------------------------------------------
4.1.1 Entering instructions
The protocol format is as follows
Command <SP> parameter <CR>
The space character <SP> separates commands from parameters and the <CR> character acts as
command line terminator.
For commands without parameter values (e.g. GT ) the <SP> character and parameter values are
omitted. The command line is as short as this:
Command <CR>
4.1.2 Incorrect instruction / error codes
If a command is not entered correctly, the reader sends one of the following error codes:
wrong instruction: <NAK> #00 <CR>
wrong value : <NAK> #02 <CR>
EEPROM error: <NAK> #03 <CR>
inputbuffer overflow: <NAK> #05 <CR>
wrong mode for instruction: <NAK> #07 <CR>
4.1.3 Upper and lower case
The instructions set isn’t case sensitive.

--------------------------------------------------------------------------------12/20--------------------------------------------------------------------------------
4.2 Change of the mode
There are 3 different modes that can be used:
Mode 1: controlling via RS232/USB
Mode 2: controlling via ARE i2
Mode 3: controlling via digital inputs
The different modes affect just the controlling of the different channels. All other instructions are still
usable via the RS232/USB interface.
You have to use the instruction VSAVE after setting the mode, to save the changes permanently.
instruction: MO <SP> 2 <CR>
answer: 2 <CR>
4.3 Changing the channel
The instruction to change the channel depends on the used mode. (see chapter 4.2)
Mode 1 (instruction on AMP) and mode 2 (instruction on i2):
instruction: MP <SP> 1 <CR>
answer: 1 <CR>
The parameter 1..8 switches the channels 1..8 for the AMP 8 and the parameters 1..4 switch the
channels 1..4 of the AMP4. The parameter 0 switches all channels off.
Mode 3:
The controlling is binary via the states of the digital inputs.
4.4 Version
This instruction is used to get the firmware version of the AMP 4/8.
instruction: VER <CR>
answer: AEG ID AMP 4 V1.423<CR>
4.5 Initialiation with default parameters
This instruction sets back the parameters to default values.

--------------------------------------------------------------------------------13/20--------------------------------------------------------------------------------
instruction: INIT <CR>
answer: ok <CR>
4.6 Saving of the parameters
The instruction VSAVE is used to store the actual parameters to the EEPROM.
instruction: VSAVE <CR>
answer: ok <CR>
4.7 Changing the baudrate
With this instruction you can change the baudrate of the AMP 4/8. The default setting is 2 (19200
baud). This instruction has to be saved with the instruction VSAVE. The AMP 4/8 is effected after a
warmstart (RST) or coldstart. If there are different settings in the AMP and the host PC it is not
possible to communicate.
instruction: BD <SP> 2 <CR>
answer: 2 <CR>
The possible baudrates are:
04800 baud
19600 baud
219200 baud
338400 baud
4.8 Warmstart with saved parameters
This instruction reboots the AMP 4/8 with the saved parameters.
instruction: RST <CR>
answer: <CR>

--------------------------------------------------------------------------------14/20--------------------------------------------------------------------------------
5System overview
The complete reading system contains the AMP 4/8 and the reader ARE i2.
There a 3 different modes to use the AMP 4/8:
Mode 1: RS232/USB communication
Mode 2: communication via the ARE i2
Mode 3: binary controlling via the digital in puts
5.1 Controlling via RS232/USB (mode 1)
Figure 2: system overview controlling via RS232/USB (mode 1)
The typical sequence in mode 1 is as follows:
1. Using the RS232 interface of the AMP 4/8
VER<CR> -> version query of the AMP 4/8 (e.g. “AMP 8 V3.012”)
MP2<CR> -> switching to antenna channel 2

5.2 Controlling via reader ARE i2 (mode 2)
Figure 4: system overview controlling via reader ARE i2 (mode 2)
In mode 2 the power supply and the data line of the AMP 4/8 is connected directly to the SAB cap of the
ARE i2.
There is a PC connection cable available with this wiring.
It is important not to change the SAB cap of the AMP 4/8 with the SAB cap of the ARE i2.
If you use your own cable be sure with the pin assignment of the AMP 4/8 (chapter 2.4.4.3) and the
ARE i2.
The typical sequence in mode 2 is as follows:

5.3 Controlling via digital inputs (mode 3)
Figure 5: system overview controlling via digital inputs (mode 3)
In mode 3 the power supply of the AMP 4/8 and the ARE i2 are seperatly. The switching of the channels
is done binary via the digital inputs. The inputs are low-activ, that means that you have to pull them to
ground to get a logical ‘1’ (see figure 6).

-B0=5V, B1=5V, B2=0V, B3=5V -> antenna channel 4 active
-B0=0V, B1=5V, B2=0V, B3=5V -> antenna channel 5 active
-B0=5V, B1=0V, B2=0V, B3=5V -> antenna channel 6 active
-B0=0V, B1=0V, B2=0V, B3=5V -> antenna channel 7 active
-B0=5V, B1=5V, B2=5V, B3=0V -> antenna channel 8 active
After switching to a new antenna channel the ARE i2 can read the transponder in the antenna field.
Attention!
Be sure that the ARE i2 is not reading (GT or MD0) while the AMP 4/8 switches the channel. The
reader can hang up or can be damaged.
6Startup and testing the AMP 4/8
Connect the reader via cable with the serial interface (COM) from your notebook or pc.
Connect the reader with your power supply (9..30V DC). Look after the polarity!
Switch the power supply on. The yellow LED of the AMP starts to blink.

--------------------------------------------------------------------------------18/20--------------------------------------------------------------------------------
Start your terminal programme. You have to set the following settings: 8 data bits, 1 start bit
und 1 stop bit, no parity check (often called 8N1), baud rate 19200 baud, no flow control(e.g.
XOFF/XON).
Send the command „VER <CR>“ to the AMP. The reader answers with the actual firmware
version (e.g. AEG ID AMP8 V1.3).
Change to mode 1 with the command “MO 1” (the default value is MO 2)
With the command “MP 1” .. “MP 8” you can change the antenna channels.
