14-22 Data Cards
Model No.
Running Head
HSU Card User Screens and Settings HSU Card
CTS
The Clear To Send (CTS) option allows you to define whether the CTS control lead should be
held on (high, asserted) or off (low, negated). Selecting either on or off will override the
selection made in the HSU Card Main Screen. The third option is norm (normal), which
allows CTS to operate in the mode selected in the HSU Card Main Screen. Not available for
820360/821460 when DTE is selected.
RLSD
The Receive Level Signal Detect (RLSD) option allows you to define whether the RLSD
control lead is held on (high) or off (low). The third option is norm (normal), which means
that RLSD will behave as described in Table 14-7. Not available for 820360/821460 when
DTE is selected.
DSR
The Data Set Ready (DSR) option allows you to define whether the DSR control lead should
be held on (high) or off (low). The third option is norm (normal), which means that DSR will
behave as described in Table 14-7. Not available for 820360/821460 when DTE is selected.

either with itself via a remote loopback or with the remote test equipment. This is an
information-only field; it is not user-configurable.

The Bit Error (BE) field indicates the total number of bit errors logged. This is an
information-only field; it is not user-configurable.

detected. This is an information-only field; it is not user-configurable.
SES
The Severely Errored Seconds (SES) field indicates the total number of seconds in which the
bit error rate exceeded one bit per thousand (1 x 10
-

). This is an information-only field; it is
not user-configurable.
