REM125 Series installation.
REM1356-5 can be installed on any place one can work with drills using M3.5 dish bolt on
marked place( ) and in case of difficulty in drilling on the side of attachment, you can
install it by using special bracket
1.2.1. Caution during REM125 Series installation.
① In case of difficulty in drilling on the face of attachment during the installation, install it
on the designated area using the special bracket.
② Install REM125 Series on the place where the operator can easily perform their
work.
③ Attaching parts or bracket must not use electric wave absorption (magnet, ferrite etc)
and metal material (SUS, AL etc). If you can’t avoid the situation you need
additional consultation.
④ Place antenna in the detection range.
⑤ Do not install near by 125KHz device or LF device.
1.3. Power connection
Insert Adaptor -from CEYON TECHNOLOGY- connector into D.C. terminal.
1.3.1. When the power is supplied normally
After power is supplied, PWR LED shows red color.
There will be 1 second buzz sound.
Operating channels are connected with each LED and once REM1356-5 turned on follows
installed mode automatically.
1.3.2. When the power is not supplied normally,
LED shows nothing.
No buzz sound.
LCD displaies any message.
1.3.3. Check the followings.
Check the power adaptor when operation is not normal.
Check the power is D.C.15v when there is no load on the power.
Confirm on polarity of power. (Make sure that the adapter is from CEYON TECHNOLOGY.)
1.4. ANTENNA Connection
The antenna terminal consists of the 6 pin din jack. The antenna cable is 2M long. In case
of the flat cable needs to be extended, the flat cable 1.5M from us may be used to extend
it for up to 3.5M. The cable may not be cut or remodeled arbitrarily. Since the tag
recognition distance depends upon the size of the antenna or the tag, we have various
kinds of approved antennas in stock. Please consult with our technical staff about the
use and the environment
1.5. Communication Line Connection
Open communication line connection between REM125 Series and HOST. REM1356-5 is
connected to the host through RS-232, RS-422 or RS-485 interface. Check the
connectable interface standard with the host and check the D-SUB 9pin drawing for
connection. Also interface can be easily change by LCD setting menu for user’s
environment.
* RS-232 is setted in the beginning. If you want to chage to RS-422 or RS-485 go to
Configuration -> Serial Interface.
1.5.1. RS-232 Serial Cable Connection Road
Use only pin No.2, No.3, No.5 during RS-232 cable connection and do notconnect the
others since the others can be used for RS-422 and RS-485 connection and for safety.

If the problem is not solved after above procedure, pull off the power cable after
turning off the system and call SEYON Technology (+82-31-267-1163).
Supplement
Supplement 1: Communication with the Host
4. Reader Operation
4.1. RF mode
1.1.1. Verbose mode
The Reader recognizes and reads the tag by operating only one channel from those in
waiting mode through the host command (CVR). The channel that is operated in
Verbose mode is activated only the specific scanning duration. If the tag is read within
that duration, the channel stops its operation and returns to the waiting mode. If the
tag is not recognized during the scanning duration, it is also returned to the waiting
mode.
1.1.2. Continuous mode
All channels of the Reader operate for the specific duration (scan weight) set for the
channel and then return to the waiting mode. The next channel is then activated and
goes through the cycle. If there is only one channel, it continuously searches the tag.
4.2. Event report mode
1.2.1 First talk mode(FT)
In this mode, the data is immediately sent to the host when the even (tag read) occurs
to the reader.
1.2.2 Listen & talk mode(LT)
The Reader stores the data in its own memory when the event occurs and sends it to
the host only when requested (CTR). In this case the data is stored in the reader until
the host request.
5. Frame
The communication between the reader and the host occurs through two types of
frames. The type of frame is determined by the transmitting device. The data in the
frame consists of ASCII code. For the numeric data, its hex value is changed to 2byte
ASCII code. The frames are described in detail below.

5.1. Command Frame(Host to Reader)
ENQ(05h)
(1byte)
d.ADD

CMD

DF

CS

Header Data Tail
2.1
ENQ (Enquiry) : This signifies the beginning of the frame and is the ASCII 05H control
character.
d.ADD (Destination Address) : ): It is the reader’s address to send the data or to
accepting data and can be within 00H ~ FFH, set as default (01).
CMD (Command) : Decide reader’s operation and send directly to the host. But the writing
and abnormal response will send back to reader
DF (Data Field) : data
CS (Checksum) : The lowest 1 byte value of the sum excluding CS is changed to 2 byte
ASCII code.

antenna called channel. Single antenna always has 1ch. FFH for sending control

6. Command
REM125 and WIM125 suport below commands. Each command display as Cxx and here
c means Command. As shown in the table CDM has 3byte and each command cowork
with data.
One important thing is that data’s 1byte Hex transforms 2byte ASCII that 6bytes long in
the frame.
Ex)CCS (08h 03h 01h)will be ‘0’’8’’0’’3’’0’’1’ and become 30h 38h 30h 33h 30h 31h in
the freame.
Such data transforming is applied to all field as ENQ, STX and ETX except control
character exgisting in ASKII.

Choice antenna to turn on at Verbose mode.
At this point setting channel need to be

Reader will send Ack immediately and
scanning tag for scanning duration time. It
will be send by FT/LT or CTR command to
host if there is a tag data.
If antenna can’t read Tag time out error
response will be send and conver to waiting
mode.
CTRn
(n ch Tag data

2nh 47h 17h None
Read specification ch’s Tag. This order
operates only within Listen&talk mode.
n’s range within 0~8ch and support 8ch.
N=0(OCTR0,20h) is mode that can read tag
data at any channel.
*CTR0 sends all channel’s data to 1 frame and
shown as 3.1.
CTWn
(n ch Tag data
Write)
3nh 47h 17h Tag data N’s range is within 1~8
As shown in the table, the command that starts with 08h is used to read the specific
control data from the reader. In that case no data field is used. The command that

starts with 2nh is used to read the tag data. In that case the third byte is the length of
the tag data and is the same as the data length of the frame. The command that starts
with 10h is used to turn On/Off the reader parameters. 1 means on and 0 means off.
The command that starts with 18h is used to send the specific data to the reader or tag.
The last byte signifies the data length. The 3nh command is used to write the data to
the tag. The tag data length is same as the third byte of the command. For the data
field, the 1 byte hex value is changed to 2 byte ASCII code like other fields before
transmission/reception. In other words, the data length of the actual frame is twice
that of the number of bytes expressed in the last byte of 08h/18h/2n/3n commands.
Figure 3.1 shows the response frame of CTR0 command. It is used to send all valid
channel tag data. The channel data format in the frame is same as 2 byte channel
information data field (DF). The length of DF is same as the last byte of the CTR
command.
