2. Connecting to the PWR series
The PWR and power supply controller are connected via a TP-BUS. Up to 32
devices can be connected to the TP-BUS.
Fig.1 TP-BUS connection
(connection example with the PIA4830)
The TP-BUS is connected in a chain by connecting twisted -pair cables to the TP-BUS
connectors (plug.) The total length of a twisted-pair cable, when connected to the series,
is 200 m or less.
In master-slave series/parallel operation, connect the TP-BUS only to the master
unit. Remote control does not work if the TP-BUS is connected to both the master
and slave units. The controller handles the PWRs connected in parallel/series as a
single master unit.

Wiring the TP-BUS connector
When using the PIA4850, the PIA4850 should be connected at the end of the b us.
1 Chec k that the POWER switch of all
deveces to be connected are turned off.
Check that the USB cable is not
connected on the PIA4850.
2 Inser t the TP-BUS connector (plug)
provided to the TP-BUS connector on
the rear panel on all units.
This f acilitates the wire connection w ork.
3 Use a wire stripper to remove the
covering from the wires.
Remove 7 mm of the covering. Use the strip
gauge that is indicated on the top panel of the
unit or the strip gauge of below.
4 Connect the wire to the TP-BUS
connector at the end of the bus.
Use the screw driver to turn the connector screw
and fix the wires in place.
5 Twist the wires (1 turn/cm).
6 Check that the wires do not come loose,
that the wires are not shorted, and that
the conducting sections of the wires are
not touching the chassis.
Communication is not possible if the wires are
shorted. If the wires are touching the chassis, the
PWR or other devices that are connected may
burn.
7 If there is any device in the middle of the
bus, twist the stripped portion of new
wires on the other side of connected
wires and connect the wires to the TP-
BUS connector.
Twist the wires (1 turn/cm).
Check that the wires do not come loose,
that the wires are not shorted, and that
the conducting sections of the wires are
not touching the chassis.
Likewise, connect the wires to all of the
devices in the middle of the bus.
TP-BUS has no polarity. You do not have to
match the polarities between units.
8 Connect the other side of connected
wire to the TP-BUS connector at the end
of the bus.

Installing a TP-BUS core
Attach a TP-BUS core to the power supply controller (excluding the PIA4850)
1 Unloc k the core(provided with PIA4800 series) and open it.
2 Wind the twisted-pair wire which is connected to the power supply
controller for once around on the half core.
K eep the distance between the core and the connector belo w 30 mm.
3 Close the core . Avoid catching the wire on the core.
Lock it securely in place.
Unlock the core
and open it.
Wind the twisted-pair wire
once around the core.
below 30 mm
Lock it securely in place.

3. Preparations for Starting Control
Settings on the Termination (TERMIN)
T urn on the termination (TERMN) on the devices at each end of the bus. The
PIA4850 is always turned on. Wire the PIA4850 at the end of the bus.
Fig.2 Termination settings
If the termination is not set properly, communications become unstable and
erroneous operation may result.
For detail of CONFIG setting, see the operation manual of the PWR series.
1 Set the CV control source and CC control source of all PWRs that are
to be connected to panel control (C-1: 0 and C-2: 0) in the CONFIG
settings.
The factory default setting is panel control.
2 Turn on the "TERMN" of the dip switch (on the rear panel) on the power
supply controller (excluding the PIA4850).
When the switch is in left position, it is turned on.
3 Turn on the termination (C-7: 1) in the CONFIG settings on the PWR at
the end of the bus.
4 Turn off the termination (C-7: 0) in the CONFIG settings on the PWRs
other than those at the end of the bus.
By factory default, the termination setting is off.

Setting of the NODE ADRESS
Assign a node address to each device on the TP-BUS for the power supply
controller to identify the devices that are connected on the TP-BUS. Set the node
address not to be the same on the TP-BUS line.
Fig.3 Display of node address “05”
1 T urn the POWER switch of PWR series on.
2 Chec k that the OUTPUT switch is turned the OUTPUT off.
If the output is turned on, press the OUTPUT switch to turn of f the output.
3 Press the ADDRESS s witch.
The v oltmeter sho ws “ Adrs”, and the ammeter sho ws the v alue.
4 T urn the setting knob to set the desired node address (05 to 36).
Do not connect de vices ha ving the same node address on the same TP-B US.
5 T urn the POWER switch off.
The node address is assigned when the PO WER switch is turned back on. Allo w at
least 10 seconds between po wer c ycles. If you turn on the PO WER switch at a short
interv al, the node address setting will be incomplete.
If you e xit from the node address setting before turning of f the PO WER switch, the
setting is cancelled.
6 Lik ewise, set the node address of all PWR seriess that are to be
connected.
