2.4.3
RESET
Activation of the front panel reset pushbutton or the reset input causes the Output relay contacts to transfer to the
no fault condition. The monitor remains in the no fault condition only if there are no existing faults and all input
voltages are at the proper operating levels. If the Minimum Flash timer is active, activation of the either reset will
zero the timer and transfer to the no fault condition.
Each activation of the front panel reset pushbutton or the reset input causes a one-time reset input to the monitor.
A continuously activated front panel reset or reset input will not prevent the monitor from checking any fault
conditions and/or transferring the Output relay contacts to the fault condition. The front panel reset or reset input
must be removed and reapplied to activate a new reset input to the monitor. Activation of either reset will cause all
of the front panel LEDs to turn on for 300 milliseconds.
The only intended purpose of the reset input is to facilitate automated testing of the monitor.
2.4.4
TYPE 16 ONLY MODE
This feature if useful in cabinets where the user is retrofitting a TS 2 monitor into a TS 1 cabinet and wants to use
the Type 16 mode, but the existing Connector A harness does not have a wire for Pin HH (Type Select).
Activating this feature forces the monitor to operate in the Type 16 mode regardless of the logic level on the Type
Select input. While this feature is on, the
TYPE 12
LED will show the Function Disabled indication (50
milliseconds on, once every two seconds).
2.4.5
COM PORT
The monitor has a front panel mounted DB-9, RS-232 communications port that can be used with Reno A&E’s
RaeComM software to view / modify configuration settings, view current status and voltages, view logs, and
download firmware upgrades. The COM port supports the standard baud rates from 300 to 57600 with one or two
stop bits and parity of odd, even, or none. The factory default is 57600, no parity, and one stop bit. The most
current version of the RaeComM software can be found on the Reno A&E web site www.editraffic.com under
support / monitor support / software. Also see Application Note AN-002 for an introduction to the RaeComM
software. This application note can be found on the web site under support / monitor support / application notes.
The monitor was designed to use a standard DB-9 extension cable (male to female, straight through) for connecting
to a laptop or computer. This port does not support handshaking signals. Both the COM port and the optional
Ethernet port can be used at the same time. See Section 3.4 for connector pin assignments.
2.4.6
ETHERNET PORT
The monitor has an optional high speed, 10BASE-T / 100BASE-TX Ethernet network jack that can be used for
communications with Reno A&E’s RaeComM software to view / modify configuration settings, view current
status and voltages, view logs, and download firmware upgrades.
To use this port an IP Address and port number must be set in the monitor. Contact your network administrator for
addresses valid for your network. The factory default is an IP Address of 192.168.1.150 (which is an unusable
address) and port 10001 (this is the recommend value).
In order to prevent the accidental writing of information to an unintended monitor, the Ethernet port is read-only on
power up. To make the Ethernet port read-write, press any pushbutton on the front of the monitor. This will
unlock the monitor for a period of 15 minutes.
2.4.7
TEMPERATURE SENSOR
The monitor is capable of monitoring the temperature inside of the cabinet. The temperature sensor is capable of
monitoring temperatures in the range of -40
°
F to +214
°
F (-40
°
C to +101
°
C). The internal cabinet temperature is
included in the data logged into the Prior Faults Log when a fault occurs. If the actual temperature inside the
cabinet is below -40
°
F (-40
°
C) at the time the fault occurs, the temperature is logged as -40
°
F (-40
°
C). If the
actual temperature inside the cabinet is above +214
°
F (+101
°
C) at the time the fault occurs, the temperature is
logged as +214
°
F (+101
°
C).
2.4.8
REAL TIME CLOCK
The monitor has a Real Time Clock (RTC) that is used as a reference for all date and time stamped events that are
logged by the monitor. The Real Time Clock is initialized to local Pacific Standard Time when the unit is
undergoing final test. In addition, the Daylight Saving Time user option is set to Off.
The Real Time Clock is preprogrammed to recognize Leap Years and Daylight Saving Time events through the
year 2099. Currently, per U.S. Federal standards, Daylight Saving Time is observed in the United States from 2:00
A.M. on the second Sunday in March until 2:00 A.M. on the first Sunday in November.
The update priority of any time setting that affects the Real Time Clock is as follows:
1.
Controller Time - The Real Time Clock is programmed with the time setting received from the Controller.
This information is received via the PORT 1 SDLC connector on the front of the monitor. If the Real
Time Clock setting differs from the Controller Time setting by more than two (2) seconds, The Real Time
Clock will be synchronized to the Controller clock. In the event that the Real Time Clock setting differs
