RS-232C Serial Port -
The serial port can operate at a maximum baud rate of 115,200
and will send / receive data in a serial fashion. See section 2.2.3.8 for more description.
4. IEEE-488
GPIB
–The IEEE-488 GPIB port enables the unit to function as a talker-listener
as well as operate at speeds much faster than the serial bus, which will send / receive
data in a parallel fashion. This will allow DFR and EMTP files to be downloaded at a
faster rate. See section 2.2.3.9 for more description.
5.
Ethernet 10BaseT
– The Ethernet 10BaseT port will typically operate very efficiently and
effectively in real time. This port is the fastest communication method within this unit.
The setup will be similar to Microsoft
®
Windows where one may set the protocol. In
addition, this port provides the optimal method for downloading EMTP files, DFR
streaming, and updating the unit’s firmware as required. See sections 2.2.3.7 and 6.2 for
more descriptions.
6.
USB Interface
– Provides a communication port for connecting external devices, such as
the optional external binary input/output box to the unit (when more than 10 binary inputs
and/or more than 6 binary outputs are required).
7.
EPOCH High Current Interface Port
–The High Current Interface port is provided on the
rear panel of the unit. It is designed to interface with the Multi-Amp Models EPOCH-II or
EPOCH-20 High-Current Output Units (reference the EPOCH-20 or EPOCH-II Bulletins
for output specifications). This port interfaces with the optional interface module box to
provide control of up to three EPOCH-20 or EPOCH-II current amplitude, phase angle
and frequency outputs. Status of the EPOCH-20/II output can be seen on the TVI display.
8. External Clock –The external clock has separate input and output connections. The
Clock In
is used in conjunction with a Clock Out from another unit or other clock source
for multiple unit operations or other special test applications. The
Clock Out
provides a
24 KHz clock signal to another unit that phase locks these units together.
9. External Trigger –The External Trigger has separate input and output connections. They
enable the unit to sync with another unit, or TTL (+ 5Vdc) signal source such as a GPS
satellite receiver. The
Trigger In
is used in conjunction with another unit to establish a
trigger for a special operation or programmed event. Typically the Trigger In
synchronizes to the Trigger Out unit and acts as a slave to it. The
Trigger Out
provides a
TTL digital signal to another unit in order to synchronize a multiple unit operation when it
needs to establish a trigger for a special operation or programmed event. The TTL signal
and pulse width for the GPS receiver is:
Voltage Input Signal: 3V peak minimum
Pulse Width: 50
µ
S nominal
10.
PRINTER Interface Port
–
For future use (not used at this time).
Voltage/Current Modules (or V/I Gen).
–There are four available slots for the Voltage/Current
Amplifier Modules. The slots are numbered from right to left with the back of the unit facing you.
Looking at the back of the unit, the rightmost slot equates to Phase A; the second slot from the
right equates to Phase B; the third slot from the right equates to Phase C; and left most slot may
be used to provide a fourth phase, polarizing voltage and/or current, residual voltage and/or
current, or other required sources.
