.SH DESCRIPTION

\fIe1432_set_tach_max_time\fR sets the maximum time between tachometer
pulses of a single channel or group of channels, \fIID\fR.

\fIe1432_get_tach_max_time\fR returns the current value of the tach
maximum time, of a single channel or group of channels \fIID\fR, into
a memory location pointed to by \fItach_max_time\fR.

\fIhw\fR must be the result of a successful call to
\fIe1432_assign_channel_numbers\fR, and specifies the group of
hardware to talk to.

\fIID\fR is either the ID of a group of tach channels that was obtained
with a call to \fIe1432_create_channel_group\fR, or the ID of a single
channel.

\fItach_max_time\fR is the maximum amount of time between valid tach
edges before the rpm value of the tach channel is set to zero, indicating
that the tach may be disconnected.

For input channels and source channels, this parameter is not used.
.SH "RESET VALUE"
After a reset, the \fItach_max_time\fR defaults to 30.0 seconds. 
.SH "RETURN VALUE"
Return 0 if successful, a (negative) error number otherwise.
