Page 4: Read Me First
READ ME FIRST Thank you for purchasing this ADR2010 serial data acquisition interface. There are three steps to using the ADR2010. 1.Connecting your computer or terminal to the ADR2010. 2.Providing power to the ADR2010. 3.Sending commands to the ADR2010. This manual will provide guidance for completing these steps along with BASIC and TURBO C programming tips. -
Page 5: A) The Adr2010 Rs232 Interface
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. -

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 pow er supply connection as perm anent damage to the ADR2010 may result if connected improperly. - Page 7 Sets I/O line specified by n in PORT A.

3. ADR2010 COMMANDS a) ANALOG INPUT COMMANDS There are 8 analog inputs, with a resolution of 12-bits, on the ADR2010 labeled AN0 to AN7. The analog input range is 0-5 VDC , 0-10VDC, +/- 5VDC, or +/- 10VDC. The input range is automatically selected by the command used to read a specific port. -
Page 9: B) Pwm Output Commands
The ADR2010 has two PW M outputs on terminals V1 and V2. The PW M 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 Sets frequency for PW M outputs to 9.76Khz... -

Page 11: D) Event Counter Commands
( PA3 is set ) d) EVENT COUNTER COMMANDS The ADR2010 is equipped with a 16-bit event counter that accepts TTL or contact input. There are three commands available to read, and clear the event counter. If the maximum count of 65535 is reached the counter will rollover to 00000 . -

ADR2010. The command to open a serial file is shown below; 10 OPEN "COM1:9600,n,8,1,CS,DS,RS" AS#1 This line opens a serial file and labels it as serial file #1. This allows access to the ADR2010 using PRINT#1 and INPUT#1 commands. SENDING COMMANDS Sending commands in BASIC to the ADR2010 can be done using PRINT#1 commands. -
