1.0 Introduction
The power distribution unit (PDU) is a multifunctional AC power distribution unit designed
to control eight AC loads and monitor vital parameters. The PDU has two main
configurations. The first configuration has a single input and eight outputs. The second
configuration has two independent inputs and each of the inputs has four outputs
associated with it. There are various current ratings available. Each input has a circuit
breaker to protect the PDU and associated loads. A programmable software current limit
is also available for added protection. The communication and control circuitry is
protected by internal fuses. The unit can still communicate when the circuit breaker is in
the tripped position.
The PDU is capable of monitoring line voltage and total load current as well as line
frequency and external temperature (with an option sensor). Operation/control is
accomplished by several communication schemes using a remote computing device such
as a laptop computer, desktop computer, or other personal electronic device.
This product complies with FCC, CE, TUV, UL60950 and IEC950 requirements.
2.0 Safety Information
This installation and operation manual contains information about the Power Distribution
Unit and basic installation instructions. The person installing or integrating the PDU into
an electronic system must be supplied with this manual and they must read it to become
familiar with the installation precautions. The manufacturing company cannot be held
liable for any damage to persons or property if the safety information in the installation
and operation manual is not followed.
If the safety information is not observed, personnel could be put at risk. Only authorized
personnel who have been properly trained may operate the device. There are no user
serviceable parts inside and any modifications made to the unit by any organization or
persons other than the factory are not permitted.
The general regulations governing the use of electricity in the country in which the device
or integrated system is installed must be observed.

4.0 Connections and Installation Information
4.1 Operating Environment
•Locate PDU in dry area on a bench, desktop or shelf.
•Rack Mount in equipment rack using mounting brackets. PDU may be
flush with front of rack or center mounted.
•Elevated Operating Ambient—If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may
be greater than room ambient. Therefore, consideration should be given
to installing the equipment in an environment compatible with the
maximum ratings of the product.
•Installation of the equipment should be such that the amount of airflow
required for safe operation of the equipment is not compromised.
•Mounting of the equipment in the rack should be such that a hazardous
condition is not achieved due to uneven mechanical loading.
•Consideration should be given to the connection of the equipment to the
supply circuit and the effect that overloading of the circuits might have on
over current protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this
concern.
•Reliable earthing of equipment should be maintained. Particular attention
should be given to supply connections other than direct connections to the
branch circuit (e.g. use of power strips). Consult the local electrical code
for additional information.
4.2 Electrical Connections
4.2.1 For 120 VAC products:
•Depress rocker handle of all circuit breakers to “off” position,
Figure 4.2.
•Connect a 3-conductor AC line cord, Figure 4.1 Item A, to the
power entry module(s) at the rear panel, Figure 4.1 Item B. Cord
must be rated at least or more than the input current rating of the
PDU. Power source must also be rated for appropriately and
have a ground.
•Connect equipment to AC outputs, Figure 4.1 Item C.
Continuous current draw for all connected units must not exceed
the current rating per output group.
CAUTION:
Power source for PDU must be properly grounded.
Cord for PDU must be rated at least or more than the rating of the PDU.
Total current for all connected units must not exceed the current rating per
input.

4.2.2 For 230 VAC products
•Depress rocker handle of all circuit breakers to “off” position,
Figure 4.2.
•Connect a 3-conductor AC line cord, Figure 4.1 Item A, to the
power entry module(s) at the rear panel, Figure 4.1 Item B. Cord
must be rated equal to or greater than the rating of the PDU.
Power source must also be appropriately sized and have a
ground.
•Connect equipment to AC outputs, Figure 4.1 Item A.
Continuous current draw for all connected units must not exceed
the current rating per output group.
CAUTION:
Power source for PDU must be properly grounded.
Cord for PDU must be rated equal to or greater than the rating of the PDU.
Total current for all connected units must not exceed the current rating per
input.
4.3 Communication Hook Up
For LAN communications plug into the front RJ-45 jack Figure 4.2 Item
G. When connecting to a 10 Base- 10/100 Ethernet LAN hub or router,
use a straight through LAN cable. Use a crossover cable if connecting
the PDU directly to a PC LAN port.
For RS-232 to PC or laptop computer use a straight through serial
cable to the RS-232 (DB-9S) connector on front panel, Figure 4.2D.
Connector pin-outs are shown in Figure 4.2 Item E. Palm PDAs
connect directly to the DB-9P connector on the front panel, Figure 4.2F.
A null modem is not required.
RS-485/RS-422 interfacing is available at rear panel 6 position modular
jack (RJ11), Figure 4.1 Item D. Caution: Do not connect this jack to a
telephone network.
Consult Factory for additional Assistance with this communication
Scheme.
CAUTION:
Do not connect any cable to rear RJ11 connector unless the internal
configuration of this connector is known. Damage to the PDU or connecting
computing device may occur.
4.4 Auxiliary Input and Output Connections
•Temperature probe input, isolated inputs and programmable isolated relay
outputs are connected to header on rear of the unit. Figure 4.1 Item E,
shows the location and designation of the connections. A pluggable mating
connector with screw clamp type terminals is supplied with the unit. Pin-outs
are shown in Figure 4.1 Item F.
•The temperature probe should be of a type using a TMP35, LM35 or
equivalent based an a two wire current based circuit with a 881 ohm scaling
resistor.
•See commands for direct relay control AFFCA, and AFFCB in Section 5 for
information on setting up the programmable relays.

5.0 Operational Commands
The PDU is shipped with a factory default setting of address FF. All basic commands
would begin with “AFF”. If the unit address is changed to another hex number the
command structure would also change. All control and configuration of the PDU settings
can be changed using the command set below. LAN module configuration can only be
performed through the LAN connection. Please see section 7.0 for LAN module
configuration.
The basic commands are valid only when the PDU is in the “remote” mode and the user
is communicating using RS-232, RS422/485 or Telnet. If an external software program is
used to issue commands, a delay of 10 milliseconds should be used between characters
and 40 milliseconds between commands being sent should be used. If the user is typing
the commands below no delays are necessary as the communication scheme can keep
up with the speed of the human interface.
PDU Commands
The following commands are based on factory default settings.
All commands must be followed by a carriage return. For 1X8
units use the “A” commands, for 2X4 units use the “A” and “B”
commands.

RESTORE FACTORY DEFAULTS
AFFZ Changes all settings back to factory default UFFZ
Notes:
1. All initiated messages are prefixed with Axx, where “A” is an ASCII upper case
character (Hex code = 41). “xx” is a two-character hex code address in the range
00 to FF representing an ASCII code address range from 0 to 128. Hex address
00 is the general broadcast address to all devices.
2. All commands & responses end with an ASCII carriage return character (Hex code
= 0D)
3. Any command can be aborted prior to sending a carriage return by sending a
Cancel (Hex = 18), or Escape (Hex = 1B) character. The PDU will discard any
previous characters, and immediately look for a valid address header.
4. PDU’s that receive messages with a correct address, but fail to recognize the
specific command parameters, or have illegal command parameters, will return a
response with the command that was entered followed by a “?”
5. Unit will respond to a broadcast command with address “00” only if the “Start”
button is depressed while the PDU is in the remote operation mode.
6. Lowest measured temperature is 0oC. There is no indication of minus temperature.
