1.B.2 The PentaMetric display unit (PM-100-C)
The PentaMetric display unit is designed to be customized for simple or complex systems.
The display unit (see figure 2) allows observation of all parameters which the input unit measures--
however most applications will require monitoring only some of these--in some cases only a small
number. The display unit has a two line 16 character LCD display, and also a sounder for audible
alarms. The display unit provides 5 “data select” buttons which allow access to the most commonly
used data. Each button can be assigned to display from 1 to 5 parameters of choice, according to
the user’s custom application. Thus it can be set up to measure many things for complex systems,
or each button can be assigned only one or two display items, for simpler applications. A
customized label may then be printed using a PC (computer) printer with descriptions according to
how the switches were set up, and inserted in a transparent “pocket” provided on the front, to
identify the display items assigned to each of the 5 “select” buttons. A maximum of up to 25
measurements may be shown by these 5 switches. In addition, the PentaMetric system allows
viewing and control of many “programmable parameters” to customize the monitor to a particular
system, such as shunt types, alarm and relay setpoints, what data is logged, and how the data is
presented in the display unit.
1.B.3: The three PentaMetric computer interfaces
There are now three choices of ways to access and control data from the PentaMetric by computer,
or now also through access by the internet. For this, one of the three interfaces below is required.
Connection may be made via 4 wire cable to the PentaMetric Input Unit, up to at least 300 meters
away. Using software provided for a “Windows” computer (“PMComm”) all data may be viewed,
and all programmed parameters may be controlled from the computer. Up to 6 “real time” data may
be simultaneously viewed. Also, logged data may be downloaded to the computer for display or
further analysis using a spreadsheet program such as Excel.
Here are the three computer interface types: All these will operate simultaneously with the Display
Unit (above). However only one of the following may be used at one time:
1. RS232 interface: (PM-100-C) This connects to an older computer “RS232” serial
connector.
2. USB interface.(PM-102-USB) This connects to the USB connector of a computer.
3. Ethernet interface.(PM-101-CE) This connects to an Ethernet connection on a computer
and may be accessed there, or may connect directly to an internet router. If the
PentaMetric location has a static IP address, then PentaMetric data may be accessed
anywhere (remotely) on the internet.
