Setting parity on 7400A DCE
Next you need to identify the type of parity coding that the data module should
expect. Parity is an error-detection scheme that is based on the value of a parity
bit in each unit of information. Four coding schemes are used: ODD, EVEN,
MARK, and SPACE. In odd-parity coding, the parity bit is set to 0 if the number of
1s in the information is odd, 1 if it is even. In even-parity coding, the parity bit is
set to 0 if the number of 1s in the information is even, 1 if it is odd. Mark-parity
coding always sets the parity bit to 1. Space-parity coding always sets the parity
bit to 0.
1. Accept the default value, unless otherwise instructed. When the SET
PARITY? prompt appears, press the NEXT/NO button to keep the default,
SPACE.
Enabling remote loopback testing on 7400A DCE
You can set the remote loopback option to GRANT
or DENY.
1. Accept the default value, unless otherwise instructed. When the SET
REMOTE LOOP? prompt appears, press the NEXT/NO button to keep the
default, GRANT
.
