4. If this does not succeed, try changing Cscape’s Target IP Address (Figure 4.1) to match
the static IP Address parameter (even if it is grayed out).
5. If all else fails, connect a PC running Cscape directly to the target OCS unit’s
programming serial port, repeat the download, and then use Data Watch to examine the
register indicated by the IP Addr Register parameter (Figure 3.5 [page 18]), to discover
the Ethernet Module’s new IP Address.
Note: If the application programmer wants to use CsCAN over Ethernet to intentionally change
an Ethernet Module’s IP Address, do this by (1) starting the download, (2) waiting for
Cscape to timeout and (3) performing steps 1, 2 and 3 of the recovery process, as
described above.
4.5 CsCAN over Ethernet Security
To prevent the use of CsCAN over Ethernet protocol to gain unauthorized access to an OCS or
RCS, Cscape Programming Software and OCS Ethernet Firmware have the ability to password-
protect CsCAN over Ethernet communication. To implement CsCAN over Ethernet Security, use
Cscape Programming Software, to perform the following nine steps:
1. Open the user program previously created for the target OCS or RCS controller.
2. IF THE USER PROGRAM HAS ALREADY BEEN SET UP WITH SECURITY
PASSWORDS, FIRST LOG-IN AS THE ADMINISTRATOR. TO DO THIS, SELECT THE
TOOLS MENU AND ITS SECURITY SUB-MENU, CLICK LOG-IN, ENTER THE
ADMINISTRATOR PASSWORD, AND THEN CLICK OK. CSCAPE WILL THEN
ACKNOWLEDGE THE ADMINISTRATOR LOG-IN; CLICK OK AGAIN
.
3. On the main Cscape screen, select the Tools menu and its Security sub-menu, and then
click Change Passwords, to open the Security Passwords dialog, as shown in Figure 4.3.

4. Click on the View Passwords button to view the Administrator and User passwords.
5. Change passwords and user names as desired for the application. Note that passwords are
numeric values between 1 and 999,999, while the user names can be any text from 1 to 15
characters long.
