Once the audible cut-off is selected the alarms present in the system are listed.
An indicator on the default front panel screen is provided to inform that the
audible alarm cutoff is active. The audible alarm can also be turned-back on
following similar procedures.
The audible alarm may be disabled altogether through proper configuration at
the front panel or through remote means.
Voltage Test Jacks
The Pulsar Plus NE843 has three test jacks that allow you to measure the system output voltage
with a hand-held meter. The jacks are referenced with C (Common), V1 (Voltage One), and V2
(Voltage Two). The voltage references correspond to the voltage referenced on the default front
panel screen.
Thus, one system voltage can be measured between C and V1 and a second output
voltage can be measured between C and V2. A voltage will not be present on one of the
voltage test jacks if the controller resides in only a single voltage system.
Local and Remote Access Ports
The Pulsar Plus NE843 provides ports for both local and remote access. Access to these
ports depends on the specific NE843 configuration. The NE843A and NE843C have a
front panel located to the left of the test jacks that provide access to a local DB-9 RS232
asynchronous serial port in some configurations. There is also space allocated for an
RJ45 receptacle that will be used to access a second 10/100Base-T Ethernet port in the
future. NE843A and NE843B controller configurations provide an RJ45 located at the
side of the chassis to access Ethernet port that is integrated into all NE843 configurations.
NE843 configuration options also provide a standard RJ11 for the telephone line interface
located on the side of the slot-controllers or directly on the modem itself.
