General
MJK Comtroller 702 is developed for control and
surveillance of small pumping stations and water
borings. Comtroller 702 is a complete unit with in-
and outputs, CPU, data logger, real time clock and
communications port for data transmission on
owned lines.
Comtroller 702 is an advanced product based on
the experience from the thousands of monitoring
systems delivered during the past 15 years.
Comtroler 702 is an advanced product for on-site
mounting with control, data logging storing and
transmission of analog and digital measuring values
to be used in both small and large SCADA sy-
stems.
Comtroller 702 is typically arranged in clusters
where each Comtroller is connected to a 2-wire
communications line. A Data Transmitter 795 is
then connected as a master communications unit.
Every single Comtroller 702 can be called
individually by their different ID numbers, and the
Data Transmitter 795 simply handles the data
transmission via a telephone modem, a radio
transceiver or a GSM modem directly to the
SCADA system.
Comtroller 702 has all necessary functions built in
such as interface to measuring and control
equipment, a data logger, counters and data
transmission. Comtroller 702 is programmed directly
from a PC, from the SCADA system or via a MJK
Data Transmitter 795 as a master communications
unit.
Comtroller 702 is a compact unit containing all
necessary functions such as communications inter-
face and drivers, software, I/O ports, data storage
memory and RS485 repeater.
Comtroller 702 is simple and economic to utilize
since it contains all necessary facilities to decrease
the number of external components needed to
form a complete unit for control, monitoring and
data transmission.
The RS 232 port is used for interconnection
through external modems, GSM-modems or a PC
for configuring or data readout.

MJK-Link™
The MS-Windows™-based program MJK-Link™
can be used for monitoring one or more Comtroller
702. It is possible with MJK-Link™ via a PC with a
modem to read realtime values, stored values for
investigation of storm flows and changing of
setpoints.
This manual deals with MJK Comtroller 702 with
Comli-protocol for telephone modems. GSM-
modems, RS 485 on owned lines, powerline
modems and closed radio networks.
