FMP Programmer’s Guide
4.6.2 EBCDIC/CRC-16
When this setting is used, the FMP control sequences are transmitted in 8-bit EBCDIC
format, and the CRC-16 block check polynomial is performed. The parity option is
ignored when using EBCDIC/CRC-16.
4.6.3 ASCII/CRC-16
When this setting is used, the FMP control sequences are transmitted in 7-bit ASCII
(space parity) format, and the CRC-16 block check polynomial is performed. Data par-
ity checking is disabled when using ASCII/CRC-16.
4.6.4 ASCII/LRC-8 OR’d with 0x40 Hex
This setting is used with the Hong Kong Foreign Exchange feed. The FMP control
sequences are transmitted in 7-bit ASCII format with LRC-8 block checking
OR’d with
0x40 hex.
4.6.5 EBCDIC/CCITT-0
When this setting is used, the FMP control sequences are transmitted in 8-bit EBCDIC,
and the CCITT-0 block check polynomial (X
16
+ X
12
+ X
5
+1) is used. The parity option
is ignored when using EBCDIC/CCITT-0.
4.6.6 ASCII/CCITT-0
When this setting is used, the FMP software uses the CCITT-0 block check polynomial
(X
16
+ X
12
+ X
5
+1) on all input and output ASCII data blocks. The parity option is
ignored when using ASCII/CCITT-0
4.7 Transmission Block Size Option (8)
The transmission block size is selectable from 64 through 4096 bytes. This value con-
trols the size of the data blocks transferred over the data link. The size of the transmis-
sion block includes the bisynchronous text control characters as well as the data
