USER PROGRAMMABLE CAP
For all hardware flow control, CTS and
DTR Switch 7 options must not be in
the forced active position.
For no flow control and normal
software flow controls (such as
X-ON/X-OFF and ENQ/ACK), the CTS
and DTR Switch 7 options should be in
the forced active position. See Tables 4-7
and 4-8 for Switch 7 Option settings
3.4 Setting the Mark and Space Parity
In some cases, it is possible to use mark and space
parity. A mark parity bit represents a binary 1. A
space parity bit represents a binary 0.
To use either mark or space parity, Position 4 must
be OFF (to disable even or odd parity) and the
following conditions must be met.
10
NOTE
• For Mark Parity — Mark parity can be used only
if your device is using a word structure
containing one stop bit. Set Positions 1 and 2
ON (2 stop bits). The first stop bit appears as a
mark parity bit.
• For Space Parity — Set the data bit switches for
one more data bit than the data code set
requires. For example, if your device is using the
7-bit ASCII code set, set Positions 5 and 6 for 8-
bit data (7 + 1 = 8). The extra data bit appears as
the space parity bit. The data bits required to
represent a character in each code set are as
follows:
ASCII
7
EBCDIC
8
BAUDOT
5
TICKER TAPE
6
TRANSCODE
6
NOTE
Space parity cannot be used for 8-bit
EBCDIC data because the CAP cannot
be configured for 9 bits.
