Chapter 1 Overview
TimeWatch Probe Module (TA 7500 only)
GPS Antenna (SMA)
N/A for implementation in TimeAnalyzer.
GPS Antenna (LOS LED)
N/A for implementation in TimeAnalyzer.
GSM Antenna (SMA)
N/A for implementation in TimeAnalyzer.
PSTN Analogue Modem (RJ11)
This connector is used for connecting the probe to a PSTN network for
communication with the server. An optional internal PSTN modem must be installed
to enable this option. N/A for implementation in TimeAnalyzer.
LAN (RJ45)
This connector is used for connecting the probe to an Ethernet network to enable
communication with the server. It is available on all TimeWatch variants. The probe
will automatically detect the data rate of the network; however it may be necessary
to configure other network parameters before normal operation. This port will
auto-negotiate and run at speeds of either 10 or 100BASE-T.
Alarm Relay Contact
This interface uses a three pin terminal block with Normally Open, Common and
Normally Closed pins. It can optionally be connected to an external alarm
management system. If an MTIE exception occurs, the relays will be switched and
will remain in the active state until a minimum of 15 minutes after MTIE is within the
configured mask. The relay will also be in its alarm state if power fails to the probe
or if any hardware fault is detected, for example loss of Measure In signal.
Power (-48vDC)
This is the power supply connector and has four pins. Pin 1 is the positive voltage
V+, nominally 0V; pin 2 is the negative voltage, nominally -48V; pin 3 is ground; pin
4 is unused. Power is provided from TimeAnalyzer’s power distribution panel.
