IQ 2000/5000 Installation Manual
Figure 3.16 shows typical RS-232C connections between a personal computer (PC) and the PDM.
These diagrams illustrates the connections required for programming a single PDM.
For RS-422 connections between an IQ and the host computer, refer to “Networking IQ 2000/
5000 Controls” on page 3-21.
Establishing Communications between IQ Master and the PDM
1. Connect the serial cable between PDM connector P6 and a serial communications port
on the PC.
2. Start IQ Master.
3. Go to the Diagnostics menu and select Version. If a dialog box with the version is dis-
played, your communications are working properly. If you get an error message pro-
ceed with step 4.
4. If you have selected an address on the address DIP switches, verify that the same
address is selected in the Communications menu, Axis Select dialog box.
5. If you get an “IQ not responding” error message, go to the Communications menu, PC
Setup and check your communications setup. You should first verify that the communi-
cations port that you have selected is the one that your cable is connected to. Then ver-
ify that the communications protocol matches the protocol in the PDM. If this is not a
new PDM any of these setting may have been changed by the previous user. The factory
settings for a new PDM are listed above.
6. Verify that the serial cable is constructed properly
7. Verify that your system has the serial communication port that you have selected. With
Windows, you received the Microsoft Diagnostic program, MSD.EXE. Exit IQ Master
and Windows and type msd at the DOS prompt. Select the Com Ports button. Verify
that there is a port address for the serial port that you have selected. Return to Windows
and IQ Master.
8. If you still have not been able to communicate with the PDM, contact Electro-Craft
Product Support.
