3.9 CONNECTINGTHE LOAD
WARNING
Turn off the AC input power before making or changing any
rear panel connection. Ensure that all connections are
securely tightened before applying power.There isapotential
shock hazard when using a power supply with a rated output
greater than 40V.
3.9.1 Load Wiring
The following considerations should be made to select wiring for connecting the load to the power
supply:
* Current carrying capacity of the wire (refer to 3.9.2)
* Insulation rating of the wire should be at least equivalent to the maximum output voltage of
the power supply.
* Maximum wire length and voltage drop (refer to 3.9.2)
* Noise and impedance effectsof the load wiring (refer to 3.9.4).
3.9.2 Current Carrying Capacity
Two factors must be considered when selecting the wire size:
1. Wires should beheavy enough not to overheat while carrying the power supply load
current at the rated load, or the current that would flow in the event the load wires were
shorted, whichever is greater.
at least
18
2. Wire size should be selected to enable voltage drop per lead to be less than 1.0V at the rated
current. Although units will compensate for up to 5V in each load wire, it is recommended to
minimize the voltage drop (1V typical maximum) to prevent excessive output power consumption from the power supply and poor dynamic response to load changes. Please refer to
Tables 3-2 and 3-3 for maximum wire length to limit voltage drop inAmerican and European
dimensions respectively.

For currents not shown in Table 3-2 and 3-3, use the formula:
Maximum length=1000/(currentxresistivity)
where current is expressed in Amperes and resistivity in ohms/km or ohms/1000ft.
3.9.3 Wire termination
The wires should be properly terminated with terminals securely attached. DO NOT use unterminated wires for load connection at the power supply.
CAUTION
When local sensing, a short from +LS or +S to -V or -S or -LS,
will cause damage to the power supply.Reversing the sense
wires might cause damage to the power supply in local and
remote sensing. (Do not connect -S to +V or +S to -V.)
19
3.9.4 Noise and Impedance Effects
To minimize the noise pickup or radiation, the load wires and remote sense wires should be twistedpairs to the shortest possible length. Shielding of sense leads may be necessary in high noise
environments. Where shielding is used, connect the shield to the chassis viaarear panel Ground
screw. Even if noise is notaconcern, the load and remote sense wires should be twisted-pairs to
reduce coupling, which might impact the stability of power supply. The sense leads should be
separated from the power leads.
Twisting the load wires reduces the parasitic inductance of the cable which could produce high
frequency voltage spikes at the load and the output of power supply, because of current variation in
the load itself.
The impedance introduced between the power supply output and the load could make the ripple
and noise at the load worse than the noise at the power supply rear panel output.Additional filtering
with bypass capacitors at the load terminals may be required to bypass the high frequency load
current.
3.9.5 Inductive loads
Inductive loads can produce voltage spikes that may be harmful to the power supply.Adiode should
be connected across the output. The diode voltage and current rating should be greater than the
power supply maximum output voltage and current rating. Connect the cathode to the positive
output and the anode to the negative output of the power supply.
Where positive load transients such as back EMF fromamotor may occur, connect a surge
suppressor across the output to protect the power supply. The breakdown voltage rating of the
suppressor must be approximately 10% higher than the maximum output voltage of the power
supply.
3.9.6 Making the load connections
WARNING
Hazardous voltages may exist at the outputs and the load connections
when using a power supply with a rated output greater than 40V.To
protect personnel against accidental contact with hazardous voltages,
ensure that the load and its connections have no accessible live parts.
Ensure that the load wiring insulation rating is greater than or equal to
the maximum output voltage of the power supply.
CAUTION
Ensure that the load wiring mounting hardware does not short the output
terminals. Heavy connecting cables must have some form of strain relief
to prevent loosening the connections or bending the bus-bars.
8V to 100V Models
Refer to Fig.3-6 for connection of the load wires to the power supply bus-bars and to Fig.3-7
for mounting the bus-bars shield to the chassis.

Remote sensing is used when, in Constant Voltage mode, the load regulation is important at the
load terminals. Usetwisted or shielded wires to minimize noise pick-up. If shielded wires are used,
the shield should be connected to the ground at one point, either at the power supply chassis or the
load ground. The optimal point for the shield ground should be determined by experimentation.
3.9.9 Connecting multiple loads, radial distribution method
Fig.3-13 showsmultiple loads connected to one supply. Each load should be connected to the
power supply’s output terminals using separate pairs of wires. It is recommended that each pair of
wires will be as short as possible and twisted or shielded to minimize noise pick-up and radiation.
The sense wires should be connected to the power supply output terminals or to the load with the
most critical load regulation requirement.
3.9.10 Multiple load connection with distribution terminals
If remotely located output distribution terminals are used, the power supply output terminals should
be connected to the distribution terminals by apair of twisted and/or shielded wires. Each load
should be separately connected to the remote distribution terminals (see Fig.3-14).
If remote sensing is required, the sensing wires should be connected to the distribution terminals or
at the most critical load.

3.9.11Grounding outputs
Either the positive or negative output terminals can be grounded. To avoid noise problems caused
by common-mode current flowing from the load to ground, it is recommended to ground the output
terminal as close as possible to the power supply chassis ground.
Always use twowires to connect the load to the power supply regardless of how the system is
grounded.

OUTPUT TERMINAL GROUNDING
There is a potential shock hazard at the RS232/485 and the IEEE portswhen
using power supplies with rated or combined voltage greater than 400V with the
Positive Output of the power supplies is grounded. Do not connect the Positive
Output to ground when using the RS232/485 or IEEE under the above conditions.
3.10 LOCAL AND REMOTE SENSING
The rear panel J2 sense connector is used to configure the power supply for local or remote
sensing of the output voltage. Refer to Fig.3-15 for sense connector location.
3.10.1 Sense wiring
WARNING
There isapotential shock hazard at the sense connector when using a power
supply with a rated output voltage greater than 40V. Local sense and remote
sense wires should have aminimum insulation rating equivalent or greater than
the maximum output voltage of the power supply. Ensure that the connections at
the load end are shielded to prevent accidental contact with hazardous voltages.
3.10.2 Local sensing
The power supply is shipped with the rear panel J2 sense connector wired for local sensing of the
output voltage. See Table 3-4 for J2 terminals assignment. With local sensing , the output voltage
regulation is made at the output terminals. This method does not compensate for voltage drop on
the load wires, therefore it is recommended only for low load current applications or where the load
regulation is less critical.

3.10.3 Remote sensing
WARNING
There isapotential shock hazard at the sense point when using power supply
with a rated output voltage greater than 40V. Ensure that the connections at the
load end are shielded to prevent accidental contact with hazardous voltages.
CAUTION
When using shielded sense wires, ground the shield
in one place only. The location can be the power
supply chassis or one of the output terminals.
Use remote sense where the load regulation at the load end is critical. In remote sense, the power
supply will compensate for voltage drop on the load wires. Refer to the power supply specifications
for the maximum voltage drop on load wires. The voltage drop is subtracted from the total voltage
available at the output. Follow the instructions below to configure the power supply for remote
sensing:
1. Ensure that the AC On/Off is in the Off position.
2. Remove the local sense jumpers from J2.
3. Connect the negative sense lead to terminal J2-5 (-S) and the positive sense lead to terminal
J2-1(+S) of the J2 mating connector. Ensure that the J2 mating connector is plugged securely
into the rear panel sense connector, J2.
4. Turn On the power supply.
Notes:
1. If the power supply is operating in remote sense and either the positive or negative load
wire is not connected, an internal protection circuit will activate and shut down the power
supply.To resume operation, turn the AC On/Off to the Off position, connect the open load
wire, and turn On the power supply.
2. If the power supply is operated without the remote sense lines or local sense jumpers, it will
continue to work, but the output voltage regulation will be degraded. Also, the OVP circuit may
activate and shut down the power supply.

The J1 Programming and Monitoring connector isaDB25 subminiature connector located on the
power supply rear panel. Refer to Table 4-4 for description of the connector functions. The power
supply default configuration is Local operation which does not require connections to J1. For remote
operation using J1 signals use the plug provided with power supply or equivalent type. It is essential
to use plastic body plug to conform with Safety Agency requirements. Ifashield is required for J1
wires, connect the shield toapower supply chassis ground screw.
Before making any connection, turn the AC On/Off switch to the Off position and wait until the front
panel display has turned Off.
CAUTION
The programming return terminals (12, 22 and 23) are
referenced to the -V potential of the power supply.Do not
attempt to bias any of these terminals relative to the-V or
any other potential. Use the Isolated Programming interface
option to allow control fromaprogramming source at a
different potential relative to the power supply negative
output.
CAUTION
To prevent ground loops and to maintain the isolation of the
power supply when programming from J1, use an
ungrounded programming source.
WARNING

CHAPTER 5LOCAL OPERATION
5.1 INTRODUCTION
This Chapter describes the operating modes that are not involved in programming and monitoring
the power supply via its serial communication port (RS232/RS485) or by remote analog signals.
Ensure that the REM/LOC LED on the front panel is Off, indicating Local mode. If the REM/LOC
LED is On, press the front panel REM/LOC button to change the operating mode to local.
- For information regarding remote analog programming refer to Chapter 6.
- For information regarding usage of the serial communication port refer to Chapter 7.
5.2 STANDARD OPERATION
The power supply has two basic operating modes: Constant Voltage Mode and Constant Current
Mode. The mode in which the power supply operates at any given time depends on the output
voltage setting, output current limit setting and the load resistance.
5.2.1 Constant Voltage Mode
1. In constant voltage mode, the power supply regulates the output voltageat the selected value,
while the load current varies as required by the load.
2. While the power supply operates in constant voltage mode, the VOLTAGELED on the front panel
illuminates.
3.Adjustment of the output voltage can be made when the power supply output is enabled
(Output On)or disabled (Output Off). When the output is enabled, simply rotate the VOLTAGE
encoder knob to program the output voltage. When the output is disabled, press the PREV
button and then rotate the VOLTAGE encoder knob. The VOLTAGEmeter will show the
programmed output voltage for5seconds after the adjustment has been completed.Then the
VOLTAGEmeter will display "OFF".
4.Adjustment resolution can be set to coarse or fine resolution.
Press FINE button to select between the lower and higher resolution. The FINE LED turns On
when the resolution is set to FINE.
NOTE
If after completing the adjustment, the display shows a different value
than the setting, the power supply maybeat current limit. Check the
load condition and the power supply current limit setting.
NOTE
The maximum and minimum setting values of the output voltage are
limited by the Over Volt
Refer to Sec.5.3 and 5.4 for more details.
5.2.2 Constant Current Operation
1. In constant current mode, the power supply regulates the output current at the selected value,
while the voltage varies with the load requirement.
2. While the power supply is operating in constant current mode, the CURRENT LED on the front
panel illuminates.
3.Adjustment of the output current limit can be made when the power supply output is enabled
(Output On)or disabled (Output Off).
-Disabled output (Off): Press PREV button and then rotate the Current encoder knob. The
CURRENT meter will show the programmed current limit for 5 seconds after the adjustment
has been completed. Then the VOLTAGEmeter will display "OFF".
age protection and Under Voltage limit setting.
34
- Enabled output, power supply in Constant Voltage mode: Press the PREV button and then
rotate the CURRENT encoder knob. The CURRENT meter will show the programmed
current limit for5seconds after the adjustment has been completed, and then will return to
show the actual load current.
- Enabled output, power supply in Constant Current mode: Rotate the CURRENT encoder
knob to adjust the current limit.
4. Adjustment resolution can be set to Coarse or Fine adjustment. Press the FINE button to
select between the Coarse and Fine resolution. The FINE LED turns On when the resolution
is set to FINE.
5.2.3 Automatic Crossover
If the power supply operates in Constant Voltage mode, while the load current is increased to greater
than the current limit setting, the power supply will automatically switch to Constant Current mode. If
the load is decreased to less than the current limit setting, the power supply will automatically switch
back to Constant Voltage mode.
5.3 OVER VOLTAGEPROTECTION(OVP)
The OVP circuit protects the load in the event ofaremote or local programming error orapower
supply failure. The protection circuit monitors the voltage at the power supply sense points and thus
providing the protection level at the load. Upon detection of an Over Voltage condition, the power
supply output will shut down.
5.3.1 Setting the OVP level
The OVP can be set when the power supply output is Enabled (On) or Disabled (Off). To set the OVP
level, press the OVP/UVL button, so that the CURRENT meter shows"OUP".
The VOLTAGEmeter shows the OVP setting level. Rotate the VOLTAGE encoder knob to adjust the
OVP level. The display will show "OUP" and the setting value for5seconds after the adjustment has
been completed and then will return to it's previous state.
The minimum setting level is approx. 105% of the set output voltage, or the value in Table 7-6,
whichever is higher. The maximum setting level is shown in Table5-1.
Topreview the OVP setting, press OVP/UVL
pushbutton so that the CURRENT display will show
"OUP". At this time, the VOLTAGE display will show the
OVP setting. After5seconds, the display will return to
it's previous state.

5.3.2 Activated OVP protection indications
When the OVPis activated the power supply
output shuts down. The VOLTAGE display shows
"OUP" and the ALARM LED blinks.
5.3.3 Resetting the OVP circuit
To reset the OVP circuit afterit activates:
1. Reduce the power supply Output Voltage setting below the OVP set level.
2. Ensure that the load and the sense wiring is connected properly.
3. There are four methods to reset the OVPcircuit.
3.1 Press OUT button.
3.2 Turn the power supply Off using theAC On/Off switch, wait until the front panel display turns
Off, then turn the power supply On using theAC On/Off switch.
3.3 Turn the power supply output Offand then On using the SO control (refer to sect.5.7). In this
method the power supply should be set toAuto-Restart mode.
3.4 Send OUT1 command via the RS232/485 communication port.
35
5.4 UNDER VOLTAGE LIMIT (UVL)
The UVL prevents adjustment of the output voltage below a certain limit.The combination of UVL
and OVP functions, allow the user to create a protection window for sensitive load circuitry.
5.4.1 Setting the UVL level
Setting the UVL can be made when the power supply output is Enabled (On) or Disabled (Off). To set
the UVL level, press the OVP/UVL button TWICE, so that the CURRENT meter shows “UUL”. The
VOLTAGE meter shows the UVL setting level. Rotate the VOLTAGE encoder knob to adjust the UVL
level. The display will show “UUL” and the setting value for 5 seconds after the adjustment has been
completed and then will return to it’s previous state.
UVL setting values are limited at the maximum level to approximately 95% of the Output Voltage
setting. Attempting to adjust the UVL above this limit will result in no response to the adjustment
attempt. The minimum UVL setting is zero.
5.5 FOLDBACKPROTECTION
Foldback protection will shut down the power supply output if the load current exceeds the current limit
setting level. This protection is useful when the load circuitry is sensitive to an over current condition.
5.5.1 Settingthe Foldback protection
To arm the Foldback protection, the FOLD button should be pressed so that the FOLDLED illuminates.
In this condition, transition from Constant Voltage to Constant Current mode will activate the Foldback
protection. Activation of the Foldback protection disables the power supply output, causes the ALARM
LEDto blink and display "Fb" on the VOLTAGE meter.
5.5.2 Resetting activated Foldback protection
There are four methods to reset an activated Foldback protection.
1. Press the OUT button. The power supply output is enabled and the Output Voltage and current
will return to their last setting. In this method, the Foldback protection remains armed, therefore if
the load current is higher than the current limit setting, the Foldback protection will be activated
again.
2. Press the FOLD button to cancel the Foldback protection. The power supply output will be disabled
and the VOLTAGE display will show “OFF”.Press the OUT button to enable the power supply output.
3. Turn the power supply output Off and then On using the SO control (refer to sect. 5.7). In this method
the foldback protection remains armed, therefore if the load current is higher than the current limit
setting the Foldback protection will be activated.
4. Turn the power supply Offusing the AC On/Off switch, wait until the front panel display turns Off,
then turn the unit back ON again. The power supply output is enabled and the Output Voltage and
Current will return to their last setting. In this method, the Foldback protection remains armed,
therefore if the load current is higher than the current limit setting, the Foldback protection will be
activated again.
5.6 OUTPUT ON/OFF CONTROL
TheOutput On/Off enables or disables the power supply output. Use this function to make adjustments
to either the power supply or the load without shutting off the AC power.The Output On/Off can be
activated from the front panel using the OUT button or from the rear panel J1 connector.The OUT
button can be pressed at any timeto enable or disable the power supply output. When the output is
disabled, the output voltage and current fall to zero and the VOLTAGE display shows“OFF”.
5.7 OUTPUT SHUT-OFF (SO) CONTROL VIA REAR PANEL J1 CONNECTOR
Contacts 2,3 and 15 of J1 (Fig.4-2, Item 5) serve as Output Shut-Off (SO) terminals. The SO terminals
accept a 2.5V to 15V signal or Open-Short contact to disable or enable the power supply output. The
SO function will be activated only when a transition from On to Offis detected after applying AC power
to unit. (Thus ,inAuto-Restart mode, the output will be enabled after applying AC power, even if SO is in
Off level.). After On to Off transition is detected, the SO will enable or disable the power supply output
according to the signal level or the short/open applied to J1.This function is useful for connecting power
supplies ina“Daisy-chain” (refer to section 5.16). TheSO control can be used also to reset the OVP

CAUTION
Do not connect power supplies from different
manufacturers in series or in parallel.
5.14.1 Series connection for increased output voltage
In this mode, two units are connected so that their outputs are summed. Set the current limit of
each power supply to the maximum that the load can handle without damage. It is
recommended that diodes be connected in parallel with each unit output to prevent reverse
voltage during start up sequence or in case one of the units shuts down. Each diode should be
rated to at least the power supply rated output voltage and output current. Refer to Fig.5-1 and

5.15 PARALLEL OPERATION
Up to four units of the same VOLTAGE and CURRENT rating can be connected in parallel to provide
up to four times the output current capability. One of the units operates as a master and the
remaining units are slaves. The slave units are analog programmed by the master unit.
In remote digital operation, only the master unit can be programmed by the computer while the slave
units may be connected to the computer for voltage, current and statusreadback only.
There are two methods, basic and advanced, to configure multiple supplies for parallel operation.
With both methods, Power Supplies, should be connected in a Daisy-Chain configuration.
Refer to Sec. 5.15.1, to Sec. 5.15.2 and to Sec.5.16 for detailed explanation.
5.15.1 Basic parallel operation
In this method, setting the units as Master and Slaves is made by the rear panel J1 connections and
the setup switch SW1. Each unit displays its own output current and voltage. To program the load
current, the Master unit should be programmed to the total load current divided by the number of
units in the system. Refer to the following procedure to configure multiple supplies for simple parallel
operation.
1. Setting up the Master unit
Set the master unit output voltage to the desired voltage. Program the current limit to the
desired load current limit divided by the number of parallel units. During operation, the master
unit operates in CV mode, regulating the load voltage at the programmed output voltage.
Connect the sensing circuit to local or remote sensing as shown in Fig.5-4 or Fig.5-5.
2. Setting up the slave units
-1.The output voltage of the slave units should be programmed 2%~5% higher than the output
voltage of the master unit to prevent interference with the master unit's control.
The current limit of each unit should be programmed to the desired load current limit
divided by the number of parallel units.
-2.Set the rear panel setup switch SW1 position 2 to it's up position.
-3.Set the rear panel setup switch SW1 position 3 in the same position as
SW1 position 4 of the master.
-4.Connect short between J1-8 and J1-12 (refer to Table 4-4.)
-5. Connect J1 terminal 10(IPGM) of the slave unit to J1 terminal 25(P) of the master unit.
-6. Connect J1 terminal 23(IPGM_RTN) of the slave unit to J1 terminal 12(COM) of the master
unit.
During operation the slave units operate as a controlled current source following the master
output current. It is recommended that the power system is designed so that each unit supplies
up to 95% of its current rating because of the imbalance which may be caused by cabling and
connections voltage drop.
3. Setting Over Voltage protection
The master unit OVP should be programmed to the desired OVP level. The OVP of the slave
units should be programmed to a higher value than the master OVP. When the master unit
shuts down, it programs the slave unit to zero output voltage. If a slave unit shuts down
(when its OVP is set lower than the master output voltage), only that unit would shut down
and the remaining slave units would supply all the load current.
4. Setting Foldback protection
Foldback protection if desired, may only be used with the master unit. When the master unit
shuts down it programs the slave units to zero output voltage.
5. Connection to the load
In parallel operation, power supplies can be connected in local or remote sensing. Refer to
Fig.5-4 and 5-5 for typical connections of parallel power supplies. The figures show
5.15.2 Advanced parallel operation
In this method, multiple supplies can be configured to parallel operation as a single power supply.
The total load current and output voltage are displayed by the Master unit and can be readback
from the Master unit. The Slave units display only their operating status (On, Off or Fault
condition).
Refer to the following procedure to configure multiple supplies for Advanced parallel operation.
1. Basic configuration
Repeat steps 1 to 5 in Sec. 5.15.1 (Basic parallel operation).
41
2. Setting the unitsasMaster or Slave
a) Depress and hold the FINE button for3seconds. The Master/Slave configuration will be
displayed on the Current Display.Rotate the CURRENT encoder to obtain the desired mode.
Refer to Table 5-4 for the CURRENT display and modes of operation.
b) When the desired configuration is obtained, depress and release the FINE button or wait
approx. 5 seconds.
3. Master and Slave units default operation
a) When a unit is programmedto Slave mode it enters the Remote mode with Local Lockout. In
this mode, the front panel controls are disabled to prevent accidental setting change (refer to Sec.
7.2.7 for details).
b) The Slave unitsparameters will automatically set the following:
*Output voltage to approximate. 102% of rated output voltage.
*ProgrammedCurrent to zero.
*UVL to zero volts
*AST On
*OUT On
*Foldback protection Off
*OVP to itsmaximum value
c) The Master and Slave modes are stored in the power supply EEPROM when the AC power is
Turned off. The system will return to the Master/Slave mode upon re-application of AC power.
4. CURRENT display accuracy
In the advanced parallel mode, the total current is programmed and reported by the Master.In
this method, the CURRENT display accuracy is 2%+/- 1 count. In cases that higher accuracy is
required, it is recommended to use the basic parallel operation mode.
5. To release units from Slave mode
Slave units can be released using the following procedure:
a) Depress FINE button for3seconds. The Master/Slave configuration will be displayed on the
CURRENT display.
b) Select H1 mode using the CURRENT encoder.
c) Depress FINE button again or wait 5 seconds.
d) Turn the AC power Offto store the new setting.
e) After exiting from Slave operation the unit’s parameters will be set to:
*Programmed Voltage to zero*AST OFF
*Programmed Current to zero*OUT OFF
*UVL to zero volts*Foldback protection OFF
*OVP to its maximum value*Locked Front Panel

CHAPTER 6REMOTE ANALOG PROGRAMMING
6.1 INTRODUCTION
The rear panel connector J1 allows the user to program the power supply output voltage and current
limit with an analog device. J1 also provides monitoring signals for output voltage and output current.
The programming range and monitoring signals range can be selected between 0-5V or 0-10V
using the setup switch SW1. When the power supply is in Remote Analog programming, the serial
communication port is active and can be used to read the power supply parameters.
CAUTION
COM (J1-12), VPGM_RTN (J1-22) and IPGM_ RTN (J1-23) terminals of J1
are referenced to the -Vout potential (-V). Do not connect these terminals to
any potential other than -Vout (-V), as it may damage the power supply.
6.2 LOCAL /REMOTEANALOG CONTROL
Contact 8ofJ1 (Fig. 4-2, item 5) accepts TTL signal or Open-Short contact (referenced to J1-12) to
select between Local or Remote Analog programming of the output voltage and current limit.
In Local mode, the output voltage and current limit can be programmed via the front panel VOLTAGE
and CURRENT encoders or via the RS232/485 port. In Remote Analog mode, the output voltage
and current limit can be programmedby analog voltage or by programming resistors via J1 contacts
9 and 10 (refer to sec. 6.4 and 6.5). Refer to Table 6-1 for Local/Remote Analog control (J1-8)

6. Connect the programming resistors to the mating plug of J1 as shownin Fig.6-2.
7. Set the programming resistors to the desired resistance and turn the power supply ON.
Adjust the resistors to change the power supply output.
NOTES:
1. SW1 positions 4, 5, 6 and9are not required for remote programming. Their setting can be
determined according to the application requirements.
2. The control circuits allow the user to set the output voltage and current limit up to 5% over
the model-rated maximum value. The power supply will operate within the extended range,
however it is not recommended to operate the power supply over its voltage and current
rating and performance is not guaranteed.
3. To maintain the temperature stability specification of the power supply, the resistors used for
programming should be stable and low noise resistors, with temperature coefficient of less
than 50ppm.
4. When resistive programming is used, front panel and computer control (via serial communication
port) of output voltage and current are disabled.

7.2.3 RS232 or RS485 selection
To select between RS232 or RS485 set the rear panel setup switch SW1-6 position to:
-Down for RS232
-Up for RS485
7.2.4 Baud rate setting
Five optional rates are possible: 1200, 2400, 4800, 9600 and 19200. To select the desired rate,
the following steps should be taken:
1. If the unit is in Remote mode (front panel REM/LOC LED illuminates), press REM/LOC
button to put the unit into Local mode.
2. Press and hold for approx. 3sec. the REM/LOC button. The CURRENT display will show
the communication port Baud Rate.
3. Using the CURRENT adjust encoder, select the desired Baud Rate.
7.2.5 Setting the unit into Remote or Local mode
1. The unit will be put into Remote mode only via serial communication command.
Commands that will put the unit into Remote mode are:
RSTPV n
OUT nPCn
RMT n
(for n values see Tables 7-3, 7-4, 7-5 and 7-6)
48
2. There are two Remote modes:
1. Remote:
In this mode, return to local can be made by the front panel REM/LOC or via
serial port command RMT 0. Set the unit into Remote mode via serial port
RMT 1 command.
2. Local Lockout:
In this mode the unit can be returned to Remote mode via the serial port
RMT 1 command or by turning off the AC power until the display turns off
and then turn it to on again. In Local Lockout mode, the front panel
REM/LOC button is not active. Set the unit into Local Lockout mode via
serial port RMT 2 command.
7.2.6 RS232/485 port in Local mode
When the power supply is in local mode, it can receive queries or commands. Ifaquery is received,
the power supply will reply and remain in Local mode. Ifacommand that affects the output is
received, the power supply will perform the command and change to Remote mode.
Serial commands may be sent to set the status registers and read them while the unit is in Local
mode. If the Enable registers are set (refer to section 7.8) the power supply will transmit SRQ’s while
in Local.
7.2.7 Front panel in Remote mode
Front panel control in Remote mode is disabled except for:
1. PREV: use to preview the Voltage and Current limit setting.
2. OVP/UVL: use to preview the OVP/UVL setting.
3. LOC/REM: use to set the unit into Local mode.
In Local Lockout mode, only PREV and OVP/UVLare active.
7.3 REAR PANELRS232/485 CONNECTOR
The RS232/485 interface is accessible through the rear panel RS232/485 IN and RS485 OUT
connectors. The connectors are 8 contact RJ-45. The IN and OUT connectors are used to connect

7.5.3 End of Message
The end of message is the Carriage Return character (ASCII 13). The power supply ignores the Line
Feed (ASCII 10) character.
7.5.4 Command Repeat
The backslash character “\” will cause the lastcommand to be repeated.
7.5.5 Checksum
The user may optionally add a checksum to the end of the command. The checksum is "$" followed by
two hex characters. If a command or a query has checksum, the response will also have one. There is no
CR between the command string and the "$" sign.
Example: STT?$3A
STAT?$7B
7.5.6 Acknowledge
The power supply acknowledges received commands by returning "OK"message. If an error is detected,
the power supply will return an error message. The rules of checksumapply also to the acknowledge.
If an error is detected inacommand or query, the power supply will respond with an error
message. Refer to section 7.6 for details.

CHAPTER 8ISOLATED ANALOG PROGRAMMING OPTION
8.1 INTRODUCTION
Isolated Analog Programming is an internal option card for analog programming of the Genesys
power supply series. The option is factory installed and cannot be obtained with GPIB (IEEE)
Interface. Output Voltage and Current Limit can be programmed and readback through optically
isolated signals which are isolated from all other ground references in the power supply.
There are two types of Isolated Analog programming cards:
1. 0-5V/0-10V option (PN: IS510): Using 0-5V or 0-10V signals for programming and readback.
2. 4-20mA option (PN: IS420): Using current signals for programming and readback.
