Master and Slave EDR Memory Requirements
MPEG Board Upgrade Installation 3
Master and Slave EDR Memory Requirements
The Master Enhanced Disk Recorder (EDR) board and Slave EDR board (if
present) must be upgraded to 64 megabytes of memory with the EDR Memory
Upgrade kit. If you ordered you PDR200 recently, the Master and Slave may
already have 64 megabytes of memory each. To see the amount of memory you
have on the Master and Slave EDR boards, check the Profile log for messages
regarding memory size or choose
Start | Programs | PDR Debug Tools | PDR
Diagnostics | Master EDR from the Windows NT 4.0 desktop. If your system does
not have the required memory, you will need two service kits— one kit for the
Master and one for the Slave—each with two 32-megabyte SIMMs.
If you have a large file system, it is recommended that you upgrade the local i960
memory to 32 megabytes. You will need one kit for this upgrade, containing one
32-megabyte SIMM, replacing the existing 16-megabyte SIMM.
NOTE: You should have obtained service kits for these memory upgrades at
the same time you received the MPEG field kit. If you have not installed these
memory upgrades, install them first thing when doing the MPEG upgrade; if
for some reason you have not obtained the kits, contact your Grass Valley
Group representative.
Slave EDR Requirements
You may or may not have a Slave EDR board installed in your system. Table 2
lists the cases where you need a Slave and when you don’t.
