[Characteristics]  
This is a CPU board equipped with two RS-232C channels. By its installed interpreter  
(ADVFSC®), programming is possible in a BASIC-like environment. In spite of its  
compactness, it is equipped with two 4M-bit flash ROMs, and its program area of about  
10000 steps can be used by an actual machine without any procedure such as ROM conversion  
or compiling. It can also be used as a pulse generator by itself. Its bus is C-bus-based, so an  
I/O board for 98 can also be directly used.

MPC-LNK  
MPCLNK is a network board with an objective of sharing memory data and bit-unit information. By using MPCLNK, connected equipment (personal  
computers and MPC-68K) can share 249-byte memory. Also, because a function is included for transferring data by block to a specified address,  
individual communications that used to be performed by RS-232C etc. are supported together by MPCLNK. The number of connectable units is up  
to 16. When MPCLNK and LNK-048 are combined, one unit of MPCLNK and up to 15 units of LNK-048 are connectable.  
The response speed is within 10 msec for transferring a shared variable from #1 to any other, and is the number of connection * 10 msec for changing a shared  
variable of #2-#15 except #1 or for the input status of LNK-048 to be returned to #1. In the case of up to five-unit connection which is a default factory ship-  
out condition, the response speed is within 50 msec.  
As for the distance of the communication cable, because it is based on RS-485 standard, the connection will have no problem up to several hundred meters.  
Also, the communication interface is isolated by a pulse transformer, preventing noise trouble etc. that occurs when used by different power sources.  
Connection Method  
Because MPCLNK adopted an interface based on RS-485, it  
can be easily connected via twisted-pair cables. Two connectors

PC (AT, 98) + LNK-048  
This is a remote IO for a personal computer. One LNK-048 is equipped with  
24-point input and 24-point output, and can perform reading of input from  
the host side and control of the output port. The host needs one MPCLNK,  
and the I/O unit and MPCLNK are connected via a twisted-pair cable. Because  
communication is done through an RS-485 interface, connection of plural  
LNK-048 is simple by multiple-drop bus connections of a twisted pair.  
Control and reading of the IO are performed via the UMB area of the personal  
computer (this is because MPCLNK works as a memory installed in the UMB  
area). Writing into the UMB area is reflected as is by the output port of  
LNK-048, and the input content of LNK-048 is reflected as is by the specified  
memory of the UMB. Therefore, the I/O can be directly controlled using  
application software for DOS/WINDOWS etc.

MPC-LNK (PC-LNK) is a data network connecting our MPC-68K, NEC PC98 series, and  
DOS/V machines. Unlike networks by other specifications, it does not let the host generate  
interruptions or consume system memory. MPC-LNK itself becomes a RAM board connected  
via communication, both the connected 68K and personal computer having shared variables  
usable in common.  
The connection interface uses RS-485 (750 kpps SDLC standard), where a network can be  
easily constructed by a twisted-pair multiple drop (the maximum connection length is 1.2  
km according to the RS-485 specification). MPC-LNK can be utilized not only as a pure  
68K network but also as a data exchange network for personal computers using libraries.  
(1)  
(2)  
Shared variables  
These are common variables of 249 bytes which all MPC-LNK can refer to. Shared variables  
are refreshed every 24 sec and can be changed or referred to at real time. The content set by  
the #1 station circulates to the whole every 10 msec, and the content changed by the #2 or  
latter station is reflected by the whole every n * 10 msec (n is the number of MPC-LNKs  
connected to the network, whose default value is 5). Also, 68K deals with them as 125 word-  
type variables.

IOD-024  
I/O Relay Box  
[Characteristics]  
Because the I/O connector of MPC is compact and has high density, wiring work in a large-scale system is troublesome,  
and because there is no display of the I/O, debugging is laborsome. IOD-024 connects to the I/O connector of MPC via  
a flat cable, and branches it point by point to a relay connector. Also, because each point is equipped with an LED,  
wiring debugging and system maintenance become easy. Also, interfacing a sensor containing a two-line amplifier can  
be done easily.

CEP-027 PIF-422  
In MIF-816 and MPC-68K, the pulse-signal output is not isolated. Therefore, if a driver is directly connected, noise may  
cause the controller to stall. When a high-noise driver such as an AC servo is connected, please use one of the above  
conversion interfaces depending on the kind of interface. Although PIF-422 is an RS-422 output, if an SG terminal is  
connected together, it can deal with 5V TTL-level signals.

How to Deal with Noise  
Control involving position determination control internally deals with signals of several msec. Because this signal is at a similar level to a  
noise signal, no matter what control device is used, reliability and accuracy cannot be obtained without any noise countermeasures. When  
making a device containing a position-determination control, please keep the following in mind.  
E A C 200  
Electricity leakage breaker  
Install noise filters to power lines to prevent external-noise: One for strong and another for weak electricity.  
Motor driving  
line (shielded)  
No binding with a  
binding band  
Separate driver lines for a servo motor and  
stepping motor, signal line, and DC 24V  
line, and prevent relays as much as  
possible.  
Especially for robots and such, please  
don’t bind motor driver lines, signal lines  
such as the one for an origin sensor, DC  
24V lines, etc. with the same plarail etc.

grounding  
It is not good to bind stepping motor  
driving lines and signal lines such as the  
one for an origin sensor, either.  
Relay control circuit  
MS  
A surge of AC 200V becomes fatal noise. There are noise  
countermeasures for electromagnetic switch coils and contacts. Also,  
these lines and DC 24V system should never be bound together.  
ON/OFF of induction motor etc. should be preferably done by an  
SSR with zero cross rather than by a relay.  
SSR  
Confirm that the device is grounded.  
If there is a device which stalls too frequently or produces motor position errors, there must be a clear noise source. The points are the  
surge based on control by coils and contacts (relay circuit) and driving lines of various large-scale motors. They become fatal noise in  
200V systems and a strong noise source even in DC 24V systems.  
There are plenty of coils that can become a noise source such as coils in conductors, strong AC 200V buzzers, coil noise of solenoid valves,  
etc. The first things to do in noise troubles are to look for coils and reevaluating power lines.  
Parts on the Black List  
Electromagnetically contacting parts: Noise countermeasures to coils and contacts.  
AC motor: Drive by SSR. Power line wiring.  
AC/DC solenoid: Noise measure to coils and contacts.  
200V and 100V buzzers: Electromagnetic wave measure (distance and shielding).  
Servo motor: Wiring of power line and signal lines (wire material, length, relay, and binding).

Request to Our Customers  
Concerning the application range of our products  
All of our products use general-use components. Therefore, please refrain from using them for fields requiring high reliability and for the  
purposes dealing with human life.  
Product warranty period  
We maintain or exchange for free our product which broke naturally during normal use only within one year after its shipment. If there is  
clear maintenance or exchange of a naturally broken product, please send the product to us.  
On-site service and field costs and expanded damage  
Our maintenance service is limited to inside our HQ. We will not accept any payment request of a maintenance cost which seems to be  
caused by on-site maintenance by our employee or our product. If you request for our employee to be sent, we will charge for the  
maintenance cost set separately. Our products are half products whose specific purpose or usage environment cannot be limited. We  
cannot compensate for any damage caused by using our product, either.  
Shipment to a distant place  
When shipping any device using our product to a distance place such as overseas, a specific procedure regulated by the Trade Administration  
Order is necessary. Because we have necessary materials for the procedure, please request them when you export our product. Also,  
because we cannot support the maintenance of any product shipped to a distance place as stated above, please place the responsibility of  
maintenance upon the user.  
Reliability of battery backup  
Although the nominal life of a lithium battery is more than five years, there are very rare instances where the battery life becomes  
significantly short due to defects of the battery maker or others. Also, retaining data by a battery is not perfect in principle. Although there  
is an extremely low probability, data can be lost (lightning, photographic strobe, and exposure to radiant rays). Also, there are instances  
where data are lost due to dew forming during normal transportation, and due to vibrations and extreme humidity occurring during export/  
import. When there is worry of program loss or when moving to a distant place where there is no technical staff to perform proper  
maintenance, please convert the program to a ROM. We cannot be responsible for the program loss.  
Abolishment of Freon  
Accompanying the abolishment of Freon, cleaning of our products is gradually shifting to the no-cleaning method. When a board looks  
like it is not clean, we have been using a non-cleaning type flux. There is no influence on the specification and performance. Because this  
is a measure from the standpoint of environmental protection, we ask for your understanding.  
Specification change  
Since 1996, there has been production discontinuation of 80-system ICs such as 8255 and 8251 one after another. Although we have  
been changing designs and taking measures each time to keep the compatibility current, part of normally-unused functions etc. may be  
changed. Please understand this in advance.  
Flash ROM  
In November 1996, we adopted flash ROMs. The number of warranted rewriting of a flash ROM is 100,000 times, and the data retaining  
period is 10 years (same specification as EPROM). Also, because flash ROM may be damaged if the power is cut off while its contents are  
being erased or rewritten, please use it in a stable power environment during a time of maintenance.
