GCA40–213
If you are upgrading a DXP system to 13B from software 10A or later, you may only need to change the
software card (DXPSW–DLRC) on the existing DXRAM–EXPC Random Access Memory (RAM)
memory card; however, since the release of software revision 13A for the DXP digital communications
system requires a revision B DXRAM–EXPC memory card, you may also need to upgrade the memory
card in your system to revision B.
If your DXP should still include a revision A memory card, you must install an DXRAM–UPC upgrade
kit to convert it into a revision B card at the time you upgrade the system software to 13B. The
DXRAM–UPC kit includes two memory chips (integrated circuit components) and an upgrade label.
NOTE: The DXRAM-UPC kit is not available through normal supply distribution channels. You can
obtain the DXRAM kit through Comdial Distributor Sales by calling 1-800-669-2663 and
speaking with a Distributor Sales representative.
Detailing the Software Considerations
•
The PCMMI (off-line) programming procedure is no longer available with 13B software. A
windows-based, Visual Man-Machine Interface (VMMI) programming system with help files now
replaces the PCMMI.
•
The DXP database must be at least revision 9A before you can translate it to 13B. You can use the 9A
revision of the PCMMI programming software to upload your current DXP database and then
download it to a data storage area—such as your computer's hard drive—as a revision 9A database. *
You must then use the new VMMI feature to translate this stored 9A data into a 13B database before
you load it back into the system.
•
The PC Attendant Position software must be at least revision 5A. (You must upgrade the software in
your PC Attendant to this level to be compatible with the 13A software release.*) It is a good practice
to upgrade the PC Attendant Position computer to contain at least 2 megabytes of RAM memory.
While this may not be necessary for every installation, upgrading to 2 megabytes of RAM memory
ensures that the PC Attendant Position functions properly under all conditions.
*Remember, you can download the latest VMMI, and PC Attendant software from the Comdial Technical Services
Bulletin Board by calling 1-804-978-2583 or from the World Wide Web at: http://bbs.comdial.com.
