ER-A Model SRV (Service) Mode – File Allocation Overview
ER-A440, 450T, 520 & 530 File Allocation Programming
For the ER-A440, 450T, 520, and 530 models, the following key operation is used to program file
allocation:
From SRV Mode:
XX = File Group No.
YYYYY = Desired number of Records/Blocks (items)
ZZZZZZ =Total Lines of stored data
MRS = See the Example ER-A520/530 File Table
No. Listing below:
NOTES: (1) The maximum number for “YYYYY” cannot be exceeded.
(2) ***** The maximum number is based on the total amount of available memory.
“Sister” File Groups
*Important: You must delete the “sister” file group in order to allocate file groups that are flagged with
an asterisk (See Example ER-A520/530 File Group
Listing). (e.g.: PLU/UPC Price 1 and PLU/UPC
Price 1-6 or PLU/UPC Text 1 (8 Char) and PLU/UPC Text 1 (16 Char) are considered “sister” file groups.
You can only allocate one or the other not
both.)
E.g.: The ER-A520/ER-A530 at MRS is allocated for PLU/UPC Price 1. In order to change the memory
allocation to allow for PLU/UPC Price 1-6, two things need to be considered:
1. The File Group #5 (PLU/UPC Price 1) must be deleted prior to allocating the File Group #6
(PLU/UPC Price 1-6).
2. The PLU/UPC Price 1-6 will require more memory than PLU/UPC Price 1. Optional memory may be
required.
To Delete a File Group
If you wish to free up available memory space by deleting a file group that is not required (e.g. Link
PLU, Set PLU, Dynamic UPC etc.), perform the following procedure:
From SRV Mode:
@/FOR.
(Type 0,1)
CA/AT
971
XX
@/FOR
YYYYY
@/FOR
ZZZZZ
(Type 2)
