• FDK Formatting
Before any data may be saved to floppy diskettes by the PL-3 unit, the diskettes must be formatted. Since the
save format is in MS-DOS, these diskettes may be formatted on the PC, or they may be formatted on the PL-
3 through the following steps:
(1) Connect the PL-3 to a power source. This may be either from the AC adapter, or from an ECR through
the bus direct cable. Remember, that if connecting to an ECR by the bus direct cable, never connect or
disconnect the cable to/from the ECR until the ECR power has been turned off for at least 15 seconds.
(2) Insert the floppy disk to be formatted into the PL-3 FDD.
(3) Set the PL-3 digital switch Main No. to 9, and the Sub No. to one of the following:
0 to format for 640 KB
1 to format for 720 KB
2 to format for 1.44 MB (2HD diskette only)
3 to format for 1.2 MB (2HD diskette only)
(4) Press the SAVE switch. The format will begin as indicated by the SAVE LED being illuminated. When
the SAVE LED goes out, and the display shows "00," the format operation is completed successfully.
(5) Remove the formatted diskette. Additional diskettes may be formatted in the same way.
(6) Disconnect the PL-3 from the power source. If connected to an ECR through the bus direct cable, make
sure the ECR power has been off at least 15 seconds before disconnecting the bus direct cable.
