devices, set the baud rate to match the baud rate of the
connected device. Avoid using Autobaud unless local
connections are the only types of serial connections to be
used. When Autobaud is used, the instrument will
automatically match the baud rate of the connected
computer, otherwise the computer's baud rate must be set to
match that of the instrument.
A read-only numeric code assigned to all Mercury
Instruments products used to identify the particular type of
instrument CNI4 = 8
Codes (0-1) to select if specific Time-out error codes are
transmitted while attempting a serial link Sign-on. When this
item is set to "0", (which is the recommended setting for most
applications) all instrument error codes are transmitted.
When set to "1", the CNI4 will not send Time-out errors during
serial communications. The selection of "1" is provided as a
convenience for some 3rd party communication interfaces.
The time (in seconds) the CNI4 waits for the host device to
send protocol character "ENQ" (Ctrl-E) following the "EOT"
(Ctrl-D) during instrument Sign-on. If the "ENQ" is not
received in the specified time, an error "21" (Time-out error) is
transmitted from the CNI4. This item is usually set to 7-
seconds but when a Cloud Link 4G Modem is installed, the
value must be set to at least 20-seconds. Range: 7 to 60,
The time (in seconds) the CNI4 waits for the "SN" protocol
com- mand (Sign-on) following the receipt of the "ENQ"
before issuing an error "21" (Time-out error). This item is
usually set to 7-seconds but when a Cloud Link 4G Modem is
installed, the value must be set to at least 20-seconds.
Range: 7 to 60.
No specific function for this item other than to store a
numeric value, for any reason. Examples of stored numbers:
phone #, meter #, installation date, map coordinates,
