Option 25: Printer Control
The remote receiver SCADA CPM2 sends data to the
local printer in the normal way, which can be enabled/
disabled for each line at option [25] as follows:
25: Prter Control:
Ent: + Bs:- Ack:S
123456789ABCDE :
11111111111111
Programming “1” will enable the local printer report
for this specific line.
“0” will disable the local printer for this specific line.
NOTE: When the receiver routes the data to the
serial port COM2, it needs to insert the checksum
calculation and support the protocol described in
more detail in the MLR2-SCADA manual. You can
only change the values for line cards 01 to 0E. You
cannot change the values for line cards 0F to 1E.
They will remain at their default value, which is (1).
Option 26: Printer Test
When this option is enabled, a test signal will be sent
to the printer at 05:00 and 17:00 hrs. This option is
set to “0” (OFF) by default. Press [ACK] when “26:
Printer Test” is displayed. The following message will
then be displayed:
Printer Test:1/0
0 Change to:
Enter “1” and press the [Enter] button to enable the
test feature. The CPM2 will send a test signal to the
printer at the scheduled time.
Printer message: L10 Printer Test 17:00:00 - 12/05
Option 27: Printer Width
NOTE: The 80-column mode is not supported with
SCADA installation. This new option has been
included to support the new CIS format. The new
format will be available with future line card revi-
sions. This option will set the printer width to
either 40 or 80-columns. Press [ACK] when the mes-
sage “27: Printer Width” is displayed. The follow-
ing message will then be displayed:
40/80 Column:0/1
0 Change to:
Press “1” and then [Enter] to enable the 80-column
width feature.
Option 28: Tamper Input
To view the Tamper Input / UPS Low Battery supervi-
sory, press the [ACK] button until “28: Tamper Input”
is displayed. Press [ACK], the following message will
then be displayed:
UPS/<ACK> : 0/1
0 Change to: 0
When this option is set to “0,” the TAMP terminal
when shorted to ground will send a UPS Low Battery
supervisory to the computer and activate the buzzer
and ACK LED. The buzzer will shut off when the [ACK]
button is pressed, or the UPS Low Battery is restored.
When the option is set to “1,” the TAMP terminal can
be used as a remote [ACK] button when shorted to
ground. The default setting is “0.” Connect a push-
button switch between the TAMP terminal and the
GND terminal. When shorting the TAMP terminal with
the ground, the receiver will react as if the front [ACK]
button had been pressed. This could be used to install
a remote Acknowledge button when using the
receiver in manual mode.
