Disk Drive Operations
Press the DISK menu button to access all 8150 floppy disk operations,
except software updates. These you can control from the Engineering
menu, as described earlier in this section. The 8150 uses a 3.5" floppy
disk drive built into the right side of the Control Panel, an optional
external floppy disk drive that you can connect to the rear of the Control
Panel, or an optional hard disk drive located in the Signal Chassis. The
floppy drive supports 720KB and 1.44MB DOS format floppy disks,
letting you manage files off-line on a PC. The hard disk is a 3.5" 1GB SCSI
drive initialized at the factory by Accom. The ability to save and recall
setups to and from disk makes changing switcher configurations easy.
When you press the DISK menu button, the 8150 checks to see if there
is a disk present if one of the floppy drives is selected. If so, it displays
the floppy disk files with the selected extension in the center of the menu.
If the hard drive is installed and selected, it displays its files with the
selected extension in the center of the menu.
NOTE: You should always save engineering setup,
personality, and effect files to disk before performing a
system update or removing the Main board from the Signal
Chassis. Both these actions clear the battery backed
memory in the 8150.
If you are using the Disk menu for the first time, set the current date and
time with the Misc softkey in the Disk menu, as described below. If you
have an unformatted floppy disk, you can format it in the Format
submenu, or with a DOS compatible personal computer. The 8150 can
format either 720KB or 1.44MB disks.
The menu also lets you name and add comments to disk files. If you have
a PC AT keyboard with a 5-pin DIN connector, you can connect it to the
rear Control Panel KEYBOARD port and use it to enter file names and
comments.
Setting the Date and Time
STEP 1: Press the DISK menu button, then the Misc softkey.
STEP 2: Press the Date softkey and select today’s date with the
Month, Day, and Year pushknobs. The display shows the
month, day, and year, in that order.
