1a)THE ADR2010 RS232 INTERFACE
The ADR2010 communicates via a standard RS232 port utilizing a simple three-wire interface.
The only signals used are received data (RC), transmitted data (TX) and ground (GND). Most
RS232 ports use hardware handshaking (i.e. DTR, DSR, CTS, RTS) signals to control the flow of
data on the port. For this reason the cable required to connect to the ADR2010 must have
jumpers on the DB25 end to satisfy these handshaking requirements. IBM or compatible
computers may be used as a host computer with the supplied cable. The supplied cable has the
following connections;
Figure 1: Supplied Cable Wiring Diagram
If the host computer has a 9-pin serial port connector, a 9-pin to 25-pin adapter cable will be
required to connect to the ADR2010 cable. This adaptor is available at most computer dealers. If
possible, the DB25 connector on the supplied cable may be removed and a female DB9S
connector can be soldered in its place using the following wiring diagram;
Figure 2 : Modified Wiring Diagram For 9-PIN SERIAL PORTS
If the host computer has a female DB25 connector, a male-to-male adapter is required to use the
supplied cable. This may be purchased at most computer dealers. Apple Macintosh computers
may be connected to the ADR2010 using MAC to DB25 DTE conversion cable.
Once connected to the RS232 based host computer or terminal, the RS232 port should be
configured to the following specifications to allow communication with the ADR2010.
9600 baud - 8 bit words - 1 stop bit - no parity
If using BASIC or C consult the appropriate section in this manual for details on how to configure
your serial port. If a terminal or terminal emulation program is used, configure your terminal to the
above specifications using the operations manual for your terminal equipment or terminal
emulation program.

1b)THE ADR2010 RS485 INTERFACE
The ADR2010 RS485 interface is a two-wire connection meeting all the standards of the EIA
RS485 interface specifications. The supplied cable is NOT an RS485 cable. To communicate via
RS485 the host computer must have an RS485 port and be connected directly with two wires (
TR+ and TR-). A typical connection diagram is shown in figure 2.
Figure 2 :Typical RS485 Connection
Note that both J1 and J3 are RS485 compatible ports. Connection from the host to the ADR2010
should be made using J1 and then J3 is used to enable daisy chaining additional ADR2000 series
products.
The host RS485 port should be configured with the following specifications to enable
communications to the ADR2010, 9600 Baud - 8 bit words - 1 stop bit - no parity.
Line feeds should NOT be sent after commands as they may collide with data being returned from
the ADR2010.
2.PROVIDING POWER TO THE ADR2010
The ADR2010 may be powered using a regulated 5 volt power supply or a suitable wall adaptor.
Power to daisy chained ADR2010 may also be supplied via the daisy chain cable. See the Daisy
chaining section of this manual for further information.
POWER-UP USING A 5 VOLT REGULATED SUPPLY
If the ADR2010 is to be powered using a regulated 5 volt power supply, the 5VDC and GND
connections are to be made to the ADR2010 via the main terminal block TB1. The supply must be
able to provide a minimum of 60mA and up to 240mA if the ADR2010 is to source current from the
digital outputs. Care must be taken to avoid improper power supply connection as
permanent damage to the ADR2010 may result if connected improperly. No connection to J2
is to be made if the ADR2010 is powered by a regulated 5 volt supply.
POWER-UP USING A WALL ADAPTOR
The ADR2010 has an on-board 5 volt regulator allowing the use of a 9-volt wall adaptor to power
the internal circuits. The regulator should be able to provide from 300-500mA .(MODE 68-950-1)
The regulator must have a standard 2.1mm, center negative, coaxial connector. The connector
can then be inserted into J2 on the ADR2010. When the ADR2010 is powered by a wall adaptor,
the on-board regulator also may provide a regulated 5 volts DC out to provide power to external
circuits. This 5 volt supply is available on TB1. The amount of current available depends on the
amount of current sourced by the digital ports. For safe operation no more than 100mA should
be drawn from the power terminals to power external circuits.

b) PWM OUTPUT COMMANDS
The ADR2010 has two PWM outputs on terminals V1 and V2.
The PWM modules on the ADR2010 boards can operate at three fixed output frequencies. Both
modules must operate at the same frequency and this frequency is set by the FH,FM and FL
commands
FH Sets frequency for PWM outputs to 9.76Khz
FM Sets frequency for PWM outputs to 2.44Khz
FL Sets frequency for PWM outputs to 610.Hz.
Note: if frequency is not set, default frequency is 610 Hz.
EA Turns on PWM output to Terminal V1
EB Turns on PWM output to Terminal V2
DA Disables PWM output on Terminal V1 ( V1 = high impedance )
DB Disables PWM output on Terminal V2 ( V2 = high impedance )
Note1: When PWM pins are disabled they are put into high impedance state.
TAdddd Sets the period of PWM output A on terminal V1 ( dddd=0000 to 1024 )

c) DIGITAL PORT COMMANDS
There is one, eight bit digital port on the ADR2010 labeled PORT A. The individual I/O lines are
labeled PA0-PA7. The following commands allow the user to;
-configure individual bits an input or output
-SET or RESET individual bits
-read individual bits
-read entire port in binary or decimal format
-write to entire port in binary or decimal format.
The digital port commands are;
CPAxxxxxxxx Configures each bit of PORT A . All eight bits must be specified. Order

( PA7 ,PA6, PA5, PA4 are configured as inputs and PA3, PA2, PA1, PA0 are
configured as outputs )
SPAxxxxxxxx Outputs binary data to PORT A. All eight bits must be specified.
Order is MSB-LSB. Individual bits configured as input are not
effected by this command. (x=1 or 0 )
