Conventional Two-Wire RS-485 Network: The conventional two-wire
RS-485 network uses a DIP SWITCH selectable converter to convert
host RS-232 or USB signal to a two-wire RS-485 signal. The baud rate
and data format must be set to a fixed value for the whole network. For
example, the user can choose baud rate=9600 and data format=10 bit
per character. This limitation is inconvenient for some real world
applications. The 7000 series, Adam 4000 series, Nudam 6000 series
and DATAFORTH 9B series all use a 10-bit format. Some conventional
PLC use 11-bit data format and some weight scale equipment uses 12bit. If the host-PC has to send command to remote modules, PLC and
weight scale equipment, one possibility is to use three independent
two-wire RS-485 networks. However, this may increase the system
cost and reduced the system reliability.
An other option for the user is to use many modules in the same twowire RS-485 network for real world applications. All these modules
must communicate at the same baud rate in a conventional system.
Some of those modules may be very close to the host-PC and will be
able to communicate at a high baud rate. Some modules may be far
away from the host-PC and will communicate at a low baud rate.
Because only one speed is valid in the RS-485 network, the high-speed
modules should be forced to communicate at a low speed baud rate. In
other words, the performance of the whole system should be decreased.
The 7000 Series RS-485 Network: The 7000 RS-485 network is the
most powerful and flexible two-wire RS-485 network in the world. It is a
multiple baud rate and multiple data format network system. That is to
say, all the remote modules mentioned above, PLCs and weight scale
equipment share the same RS-485 network. The 7520, RS-232 to RS485 converter, equips a “Self Tuner” inside, therefore it can detect the
baud rate and data format automatically and control the direction of the
RS-485 network precisely. Therefore the user can connect all this
equipment to the same RS-485 network. This method will greatly
reduce system cost and increase reliability.

2.8 How to select 7520 / 7520R
The 7520R is exactly the same as 7520 except for the isolation site.
The isolation site of the 7520 is located in the RS-232 interface circuit,
but the isolation site of the 7520R is located in the RS-485 interface
circuit. That is to say, the power input and RS-485 interface is common
ground for the 7520 but the power input and RS-232 interface is only
common ground for the 7520R as follows:

Note: the power ground of
7000 and RS-485 is

ground.

This is the same for Adam
4000, Nudam 6000 and
DATAFORTH 9B series
modules.

In most applications, the 7520 are used to convert the RS-232 signal to
RS-485 network. Normally the 7520 does not use the same DC power
ground as the Host PC/PLC, and the isolation site is in the RS-232 section.
Therefore the Host PC/PLC is isolated from RS-485 network. That is to say,
if there is any high voltage transient on RS-485 network, the Host PC/PLC
will be free from damage.
WARNING!! ERROR CONDITION 1: if the 7520 are replaced by 7520R and
the 7520R uses the same DC power ground with 7000. In this situation,
(1) The Host PC/PLC is common ground with RS-232
(2) The RS-232 is common ground with power ground of 7520R
(3) The power ground of 7520R is common ground with power ground of
7000
(4) The power ground of 7000 is common ground with RS-485
Therefore the Host PC/PLC is common ground with RS-485 network.
That is to say, there is no isolation between Host PC/PLC and RS-485
network. The Host PC/PLC may be damaged if there is high voltage transient
on RS-485 network.

7000 Bus Converter User Manual (version 1.2,Feb/2003, 7PH-006-10) --------------- 24

WARNING!! ERROR CONDITION 2: if the 7520 uses the same DC
power ground with Host PC/PLC (for example, Host PC/PLC
provide non-isolated DC power source to 7520). In this situation,
(1) The Host PC/PLC is common ground with power ground of 7520
(2) The power ground of 7520 is common ground with RS-485
Therefore the Host PC/PLC is common ground with RS-485 network.
That is to say, there is no isolation between Host PC/PLC and RS-485
network. So the Host PC/PLC may be damaged if there is high voltage
transient on RS-485 network.
OK CONDITION: If the DC power ground of 7520 or 7520R is not common
to any module, the Host PC/PLC will be isolated from RS-485 network in
all conditions.
The power adapter PWR-24 is designed for single 7000 series modules
only. The 24V DC output of the PWR-24 is isolated from its AC input. If the
7520 or 7520R is connected to the PWR-24, this PWR-24 cannot connect
to the other module. Normally the Host PC/PLC uses a switching power and
the DC output of this power supply is also isolated from its AC input. Therefore
the DC power ground of 7520 or 7520R is isolated from Host PC/PLC.
Therefore, the Host PC/PLC is isolated from RS-485 network in all condition.

The 7520R is designed for PLC networking. During normal
conditions, the PLC system will have a stable DC-24V power source. The
user may use this power source to 7520R(configuration A). When using
7520, the user must use another power source, PWR-24
(configuration B).

The isolation feature is very important in real world applications, therefore
the user should pay attention when selecting the correct module. If the wrong
module is selected, the isolation will be removed but the module will still
function OK. This may cause unexpected damaged by high-energy transients
on a RS-485 network.

3. I-7560 / I-7561 / I-7563

What is USB?
USB, or Universal Serial Bus is a connectivity specification developed by
computer and telecommunication industry members for attaching
peripherals to computers.
USB is designed to free all the troubles when installing external
peripherals. It eliminates the hassle to open computer case for installing
cards needed for certain devices.
It is designed to meet Microsoft Plug and Play (PnP) specification,
meaning users can install, and hot-swap devices without long installation
procedures and reboots.
The I-756x USB to RS-232 or RS-485 or RS-422 converter are your smart
and convenient accessory for connecting RS-232 serial devices to your
USB-equipped Windows host computer. It provides a bridge connection
with a standard DB 9-pin male serial port connector in one end and a
standard Type-A USB plug connector on the other end. You simply attach
the serial device onto the serial port of the cable and plug the USB
connector into your PC USB port. It allows a simple and easy way of
adding serial connections to your PC without having to go thru inserting a
serial card and traditional port configuration.
This USB to Serial adapter is ideal for connecting modems, cellular
phones, PDAs, digital cameras, card readers and other serial devices to
your computer. It provides serial connections up to 1Mbps of data transfer
rate. And since USB does not require any IRQ resource, more devices
can be attached to the system without the previous hassles of device and
resource conflicts.
Finally, the I-756x USB to Serial adapter is a fully USB Specification
compliant device and therefore supports advanced power management
such as suspend and resume operations as well as remote wakeup. The
I-756x USB Serial products are designed to work on all Windows

The Host PC/PLC will send out a command string from its RS-232
port. The 7520 will convert these RS-232 signals into a RS-485 signal
and isolate the host from RS-485 network.
The 7000 series modules, including D/I, D/O, A/D, D/A,
Timer/Counter and MMI modules, will be directly connected to RS-485.
These 7000 series modules can connect a max. Of 256 modules to the
RS-485 network without a repeater, the 7510. That it to say, there can
be 256 modules from 7xxx to 7xxx. If there are over 256 modules, the
repeater 7510 must be added to extend the RS-485 to RS-485. Then
there can be another 256 modules connected to the RS-485 network.
This is the first function of the 7510.
The module address can be changed from 00 to FF a total of 256
max. Therefore there are maxes. Of 256 modules in one RS-485 network
if all the modules communicate with the same speed.
(1) Because the 7000 can communicate with different baud rates in the
same RS-485 network, the 7xxx, 7xxx and 7xxx can be
communicated to HOST PC/PLC with a different baud rate.
(2) The 7000 series can be programmed to 1200, 2400, 4800, 9600,
19200, 38400, 57600, 115200,a total of 8 different speed.
(3) The 7000 modules can share the same module address if their baud
7000 Bus Converter User Manual (version 1.2,Feb/2003, 7PH-006-10) --------------- 73

rates are different. For example,
7xxx=module address 01, baud rate=1200
7xxx=module address 01, baud rate=9600
7xxx=module address 01, baud rate=115200
These three modules can share the same RS-485 network, generated
by 7520.
(4) Therefore there is 256*8=2048 modules max. In one RS-485 network
with a repeater (7510).
The “search function” given in NAP7000S can search for all these 2048
modules in one RS-485 network. Refer to “NAP7000S User Manual” for
completely source listing of “search function”.
When the RS-485 network is over 4000 ft or 1.2Km, the RS-485
repeater (7510) must be added to extend the RS-485 network. For
example, if the RS-485 is over 4000 ft or 1.8 Km, the 7510 must be
added to extend RS-485 to RS-485. And if the RS-485 is too long,
the user should use another 7510 to extend another RS-485 network. This
is the second function of 7510.
The power ground of the 7000 series is common ground to the RS485 network. This feature is the same as the Adam 4000, Nudam 6000
and DATAFORTH 9B series. Therefore all the modules in the same RS485 network are common ground. For example, the all modules between
7xxx and 7xxx share the same RS-485 network and all are common
ground. The RS-485 length can be up to 4000 ft or 1.2 km, this is a very
long path. This long path makes the RS-485 network very susceptible to
network noise by high energy transient in this environment. If this noise is
too great, all the modules in the RS-485 network may be damaged
simultaneously. This is highly possible and occurs often in real world
applications. It is strongly recommended to add another isolation repeater,
the 7510, to break the long path RS-485 network into several short RS485 networks to avoid all the modules being damaged at the same time.
This is the third function of 7510.

7000 Bus Converter User Manual (version 1.2,Feb/2003, 7PH-006-10) --------------- 74

For example, the 7510, 7510, 7510 are used to isolate local
modules from RS-485 network. If there is high energy transient on
RS-485 network, all the local modules will be safe.

If the RS-485 network is not over 100 meters, the terminated
resistors are not needed. However, it may be necessary to insert two
terminated resistors at both end of the RS-485 segment. It is not easy to
calculate the value of a terminator resistor. The best way to do this is to
use an oscilloscope to check the RS-485 signal directly. If the impedance
match of RS-485 network is OK, the oscilloscope will show a very nice
square wave. If these square wave signals are distorted, the user will
need to insert two terminators at both end of the RS-485 segment.

It is recommended to use the “trial and error” rule. The trial and error
rules are given as follows:
(1) If the length of RS-485 is about 1.2 Km, try 120Ω first
(2) Run TEST.EXE of NAP7000S

Select function_5, run continuously for at least 8 hours to make
sure communication is OK.
(3) If

function_5 finds many communication errors, use an
oscilloscope to check the waveform. The waveform will tell you
whether the terminator is too small or too big. Then adjust your
terminator and run TEST.EXE again.

(4)
(5) If

the correct terminators are found, run the TEST.EXE
continuously for at least 8 hours to make sure there are no
communication errors.

The function_5 of TEST.EXE, given in NAP7000S, will automatically
read “testing command” from TEST.DAT and continuously perform “sendreceive-testing”. It will continuously test and record all testing results.
Therefore this function is especially designed for RS-485 network stability
evaluation. If you run this function_5 continuously for 8 hours and find no
check errors, this means that your RS-485 network is very stable. Also
this means that your terminators match well now.
NOTE 1: The value of the terminator depends on the RS-485 wire
used. If the RS-485 path is very long, don’t use a cheaper wire. It is
recommended to select a high quality wire such as the Belden 1583A.
NOTE 2: The terminator is different for various applications.
Therefore we can’t provide a terminator with the 7520 or the 7510. The
user must choose the correct terminator by them self. It is recommended
to use a carbon, 1/4w resistor.

Every remote-PC must have a unique address. This unique address
is similar to the module address of the 7000 series. We call it a “slave-PC
address”. The module address of the 7000 series is limited to 256, but the
slave-PC address is unlimited. The user can connect thousands of PCs in
one RS-485 network by using a repeater, the 7510.
Refer to “NAP7000S User Manual” for software details. Using this
software, the host-PC can send out commands to remote-PCs, just like
sending commands to the 7000 series modules. The remote-PC will
receive these commands and execute the command if the destination
addresses matches it’s local address.
These remote-PC and 7000 series modules can use the same RS485 network. The host-PC can send out the 7000 series commands and
send out PC-networking commands at different times. The modules and
remote-PCs will receive their command respectively. This makes the
network very low cost, with high flexibility and reliability. This unique
feature is not found elsewhere in the world.

• Step 11: read the firmware number of this module

NOTE: If the user uses $AA2 command to change module configuration, the
new configuration code will be stored into EEPROM immediately. The
configuration code includes module address, module type, baud rate
code, checksum enable/disable code, calibration code, power-on value
and safe value. The EEPROM data of the 7000 series can be read an
infinite number or times and can be written about 100,000 times max.
Therefore the user should not change the configuration code often when
testing.

2. Press 2
3. Press $012[Enter]
Receive=! 01080600
4. Press 2
5. Press %0101080A00[Enter] Receive=? 01
6. Connect INIT*_pin (pin 6) to GND_pin (pin_10)
7. Press 2
8. Press %0101080A00[Enter] Receive=! 01
NOTE:
9. Press 2
(1) To change the baud rate, the

11. Power off, disconnect INIT*_pin and
GND-pin
GND_pin, power on and run test.exe
12. Press 0
(2) The baud rate will be saved into
13. Press 1[Enter](1/2/3/4 for COM 1/2/3/4)
EEPROM immediately.
14. Press 115200[Enter]
(3) The module will change its baud
15. Press 0[Enter]
rate only during the first power16. Press 2
on time.
17. Press $012[Enter] Receive=! 01080A00
• Step 3: read the module status, baud rate=9600
• Step 5: change baud rate with the INIT*_pin floating and the function will fail
failure. If the user want to change the baud rate of the 7000 module, the
INIT*_pin must be connected to the GND_Pin. If the INIT*_pin is left floating
(unconnected), the 7000 module will echo ?AA to the user.
• Step 8: change baud rate to 115200 with the INIT*_pin connected to the
GND_Pin. After this command, the baud rate will remain at 9600. The baud
rate of the 7000 series will be changed only during the power-on interval.
• Step 10: read the module status, baud rate= 115200(this value, is stored in
the EEPROM only). The baud rate is changed in step 8 but the baud rate of
this module is still at 9600 BPS. When the module has powered-off-andpowered-on, the baud rate will be changed to 115200.
• Step 11: power off, then power on. The module will change its baud rate
based on the EEPROM value only when the module has first powered-on
• Step 13-16: change TEST.EXE to baud rate 115200
• Step 17: use baud rate 115200 to read back the module status and find that
the module is now communicating at baud rate 115200.

Checksum Enable/Disable

Wire connection: Refer to Sec. 2.7
Test program: Refer to “NAP7000S User Manual” for TEST.EXE

The steps to enable/disable checksum status are given as following.
1. Wire connection, power on and run test.exe
2. Press 2
3. Press $012[Enter] Receive=! 01080600
4. Press 2
5. Press %0101080640[Enter] Receive=? 01
6. Connect the INIT*_pin (pin 6) to the GND_pin (pin_10)
7. Press 2
8. Press %0101080640[Enter] Receive=! 01
9. Press 2
10. Press $012[Enter] Receive=! 01080640
11. Power off, disconnect the INIT*_pin and the GND_pin
12. Power on and run test.exe, then press 0
13. Press 1[Enter](1/2/3/4 for COM 1/2/3/4)
14. Press 9600[Enter]
15. Press 1[Enter]
16. Press 2
17. Press $012[Enter] Receive=!01080640B1

NOTE:
(1) To enable the checksum, the INIT*-pin must be connected to the GND-pin
(2) The checksum status will be saved into the EEPROM immediately.
(3) The module will change its checksum state only during the first power-on time
(4) The TEST.EXE will send out the extra checksum byte if checksum is enabled.
(5) The 7000 will echo the extra checksum byte. The extra checksum byte is “B1” in
this example.

• Step 3: read the module status, chksum=DISABLE
• Step 5: enable checksum with the INIT*_pin floating, so the function fails. If
the user want to enable the checksum bytes of the 7000 module, the
INIT*_pin must be connected to the GND_pin. If the INIT*_pin is left floating
(unconnected), the 7000 module will echo ?AA to the user.
• Step 8: enable checksum with the INIT*_pin connected to the GND_pin.
After this command, the checksum is still in the DISABLE state. The state of
checksum will be changed only during the power-on period. But the
checksum status is saved into EEPROM immediately.
• Step 10: read the module status from EEPROM and find that checksum is in
the ENABLE state. The state of checksum was changed in step 8 but this
module is still in checksum DISABLE state. Only when the module has
powered-off-and-powered-on, the state of checksum will be changed to
ENABLE
• Step 11: power off, disconnect the INIT*_pin and the GND_pin. Power on.
The checksum status of this module is enabled now.
• Step 12-17: Changes TEST.EXE to baud rate 9600 and checksum enable,
then read back the module status and find that the module is in checksum
enable state now.
The steps to compute checksum are given as follows:

step 1: checksum=0;
1. Step 2: for all command byte checksum = checksum + command byte
2. Step 3: checksum=checksum&0xff
3. Step 4: convert checksum to ASCII high byte and ASCII low byte

For example, command = $012[Enter]
Checksum = $+0+1+2=0x24+0x30+0x31+0x32=0xB7
Checksum & 0xff = 0xB7
Checksum ASCII high byte = ASCII B = 0x42
Checksum ASCII low byte = ASCII 7 = 0x37
Command with checksum = $012B7[Enter
