The RS232 Connector on the Left Side of MC5-IS
The RS232 connector may be used when connecting to a serial
port in a PC. The PC may have a calibration software capable of
communicating with MC5-IS or, e.g. a software that reads data log-
ging results in MC5-IS and transfers them to a PC.
Warning!
Use only cables provided by Beamex when connecting MC5-IS
to a PC.
The Front Panel
The front panel has several sections. Some of them are pointed out
with a callout in the picture of Operational Sections and Connec-
tions, and some of them not (e.g. display and keyboard). The ones
with a callout are discussed first in the following paragraphs.
Electrical Module (E module)
The E module can
measure the following
quantities: voltage,
current and fre-
quency. It can also be
used when counting
pulses or detecting the
state of a switch. Additionally there is a possibility to sink current.
The E module also includes the optional HART modem. This allows
communication with an instrument with HART capabilities. To en-
sure proper HART communication, make sure that the loop also
includes a resistor with a resistance between 230 to 600 ohm or
that the impedance of the loop itself is at least 230 ohms.
Additional information on calibrating HART instruments is in Ap-
pendix 1.
