Errata Sheet
Change to Table of Contents
There is a typo on the first page of the Table of Contents. “Install” is spelled “Insall” for the section named “Install the D2-DCM”.
Change to Page 2. Introduction
Add the following note to this page:
NOTE: The D3-DCM module is only supported by the D3-350 processor only.
Change to Page 7. Specifications
In the Operating Specifications table, revise the “CPU Required” entry. It should say:
D2-240 (firmware V1.8 or later), D2-250-1 and D2-260
Change to Page 11. Building the Cable
The NOTE at the bottom of the page is incorrect. Only the D2-230 and D2-240 CPUs support RS232 only. D2-250(-1) and
D2-260 CPUs support RS232/422/485 without extra hardware.
Change to Page 12. Building the Cable (continued)
Change the refererence in the first paragraph to “Belden 9855” cable to “AutomationDirect L19772-1 (Belden 8102)
or equivalent”.
Change to Page 13. Building the Cable (continued)
In the first paragraph, change the last sentence to “For example, AutomationDirect L19772-1 (Belden 8102) or equivalent has a
nominal characteristic impedance of 100 ohms”.
In the top wiring drawing (“Line-to-Line Termination for the D2-DCM”), change both “120 Ohm Resistor” callouts to “100 Ohm
Resistor”.
In the bottom wiring drawing, change the “65 Ohm Resistors” callouts to “51 Ohm Resistors”.
In the top drawing, move the termination resistor on the left connector (Master) from the 24-25 pins to the 16-17 pins.
