Translate Table Selection
The ULTRA determines the appropriate translation table to use based upon both the user’s configuration of the ULTRA and the data stream it receives.
The output (ASCII or EBCDIC) is determined by the user’s configuration of the ULTRA using configuration Option #10. Option #11 determines if APL output is supported for DSC data streams when Option #10 is configured for ASCII output and when Option #20 is configured for EAB support.
The input is detected by analysis of the data stream by the ULTRA. When an EBCDIC character from the host arrives at the ULTRA, it may be either DSC or SCS data. See Section 14 — SCS Data Streams and Section 15 — DSC Data Streams for more information. The table to be used is selected by the ULTRA by combining the information from the input and output variables as follows:
Input:
•If the data stream is ASCII (from an alternate host), the appropriate translate table is 3 (for ASCII output) or 6 (for EBCDIC output).
•If the coax host data stream is in DSC format, the appropriate translate table is 1 (for ASCII output), 4 (EBCDIC output) or 7 (APL output).
•If the coax host data stream is in SCS format, the appropriate translate table is 2 (for ASCII output), 5 (EBCDIC output) or 8 (APL output).
Output:
•If the ULTRA is configured for ASCII output, the appropriate translate table is 1, 2 or 3.
•If the ULTRA is configured for EBCDIC output, the appropriate translate table is 4, 5 or 6.
•If the ULTRA is configured for APL output (refer to Options 10, 11 and 20), the appropriate translate table is 7 or 8.
