Easy48
Ports are listed by port reference. In this reference, the first character is the matrix reference (X = primary unit, A-F =
secondary units) and the second character is the RS232 port number (1-8) on that matrix. If a port expander has been
fitted to a RS232 port, the
Device
field for that port must be set to
Expander
. Three new rows will be added to the
screen for these expander ports, with a expander reference (a-d) added to the end of the port reference.
For each port, complete the following fields by double-clicking in the field and making the desired selection:
•
The
Device
field defines the device type connected to the port. The following options are available:
-
Alarm
should be selected when the port is used for input of alarm signals to the MegaPower 48+ system via
an AD2096A Alarm Interface Unit (AIU). A maximum of eight AD2096A units can be connected.
-
Keyboard
should be selected when the port is used for keyboard connection. For this use, set data bits to
8,
parity to
None
and stop bits to
1
.
-
Terminal
should be selected when the port is used to upload and download setup information between the
MegaPower 48+ system and a PC running Easy48. Note that only one PC can be added to the system and it
must only connected to the primary matrix (e.g., ports with a port reference beginning with X).
-
Printer
should be selected when the port is used to output messages to an RS232 serial printer.
-
Auxiliary
should be selected when the port is used for the control of auxiliary devices.
-
PIP
(Peripheral Interface Port) should be used to enable communication with a connected video recorder. It
should be noted that the Peripheral Interface Port must be enabled through the
Options
screen (see page 16)
before port parameters can be programmed for the PIP.
PIP
should only be selected for one port.
-
Modem
should be used to
enable paging communications with an external (AT command set) modem. For this
use, set the baud rate to
2400
, data bits to
7
, parity to
Even
and stop bits
to
2
. Note that the
Modem
setting
is only available for port 8 of the primary matrix (port reference X8).
-
Expander
should be selected when a RS232 port expander has been connected to the specific port. Three new
rows will be added to the screen for these expander ports, with a expander reference (a-d) added to the end of
the port reference.
Baud
,
Data Bits
,
Parity
and
Stop Bits
values cannot be altered when
Expander
is selected.
•
The
Baud Rate
field is used to select the baud rate for the port. Select from
300
,
1200
,
2400
,
4800
,
9600
,
19200
and
38400
.
•
The
Data Bits
field is used to
select the number of data bits. Select between
7
and
8
.
•
The
Parity
field is used to
select the data parity. Select from
None
,
Odd
and
Even
.
•
The
Stop Bits
field is used to
select the number of stop bits. Select between
1
and
2
.
•
The
Location
field is used to specify where the device connected to the port can be found. This can be used to help
locate an individual device when multiple units have been connected to the system. The information entered into
this field is used in
Easy48
only.
Notes
•
Once selections for a port have been made, do not change the settings unless the corresponding RS232 device is
also changed.
•
In the
Ports
screen it is possible to use the drag down method to change multiple fields in a column to the same
setting. Enter the required text or select the required option in the uppermost field and then click and drag the cursor
over the fields below that are to be set the same. Press the
Enter
key to copy the setting to the highlighted fields.
System - Time/Date
The
Time/Date
screen is used to configures the date format that the MegaPower 48+ system uses. To display this
screen, expand the
System
node on the left-hand side of the display area and then click the
Time/Date
node.
Use the drop down list to select the required format. Select from
