MEDIA CHANGER COMMANDS M2488 PRODUCT GUIDE
6-34 CG00000-011503 REV. A March 1997
The following MODE CODES are specified:
When the Inhibit Magazine Eject code is set, the Medium Changer does NOT eject the Magazine
upon either the receipt of a MOVE MEDIUM command that specifies move Import/Export Element
to Medium Transport Element (eject Magazine), or after processing the last cartridge in a Magazine
while in Automatic Mode. If Inhibit Magazine Eject is set when either of these situations occur, the
Magazine is moved to the first available cartridge (see Table 6-40 on page 6-34 for operation of car-
tridge unloading). If an ACL is attached, the Eject code is reported as changeable and defaults to a
value of 10b.
For an FACL, the Eject code is not supported. If an FACL is attached, the Eject code is reported as
NOT changeable on a MODE SENSE command and defaults to a value of zero. See Table 6-40 for
operation of cartridge unloading.
1) Move cartridge from MTU to magazine.
2) Load next cartridge.
3) Position magazine to cartridge position number 1.
4) Eject magazine.
If the HltLd (Halt Load) bit is set to 1, the Medium Changer is instructed to suspend loading of the
next cartridge following an unload of the currently loaded cartridge when the Medium Changer is set
in Automatic Mode. This function is cleared and the bit reset
a) by depressing the START key after loading has been suspended in Automatic Mode or
b) by depressing the RESET key followed by the START key when the Medium Changer is in
Automatic Mode, or
c) by a new Mode Select command with the HLTLD bit set to 0b.
