3 Input and Channel Configuration Channel Configuration 3. Set channel 401 to ON (see "Set Channels to ON or OFF" on page 3-13). 4. Assign a label to the channel if desired. 5. To measure the DIO, monitor channel Ch401 in the Scan/Monitor menu. The 8-bit TTL value is shown on the display and the decimal equivalent will be recorded to the data file. Totalizer Channel Configuration (Ch402) The Product is equipped with a unidirectional, resettable totalizer with an input count capability of 0 to 1048575 (20 bits). When a digital input is connected to the TOT input on the rear panel and Ch402 is set to on, the Product counts each time the dc voltage of the signal transitions from high to low or a contact closes to the ground (GND). When a scan is started, the TOT counter is reset to 0. The totalizer count can be manually reset at any time with  in the Scan menu. Read Mode The totalizer function has two read modes: read and read/reset. The mode can be set in Channel Setup or by remote command. The default totalizer mode is read. In read mode, the count is not effected when read during the scan sweep or read by remote command. In read/reset mode, the totalizer count is automatically reset to 0 when it is read during a scan sweep or read by remote command. It is not effected by pause scan. The totalizer count is not reset when it is viewed with the Monitor function. Debounce In some applications, contacts can "bounce" when they close that results in multiple signals on one line. Without a filter the Product detects multiple closures that can cause duplicate counts for one closure. To filter the signal, the Product has a debounce feature that can detect bounce on the signal and ignore it. Debounce (600 Hz) can be turned on with the Edit channel function of the Totalizer channel (Ch402). If the debounce feature is disabled, 10 kHz is the maximum frequency the Totalizer input can support.

To measure the DIO, monitor channel Ch401 in the Scan/Monitor menu. The

Totalizer Channel Configuration (Ch402)
The Product is equipped with a unidirectional, resettable totalizer with an input count
capability of 0 to 1048575 (20 bits). When a digital input is connected to the TOT input
on the rear panel and Ch402 is set to on, the Product counts each time the dc voltage of
the signal transitions from high to low or a contact closes to the ground (GND). When a
scan is started, the TOT counter is reset to 0. The totalizer count can be manually reset at
any time with
in the Scan menu.
Read Mode
The totalizer function has two read modes: read and read/reset. The mode can be set in
Channel Setup or by remote command. The default totalizer mode is read.
In read mode, the count is not effected when read during the scan sweep or read by
remote command.
In read/reset mode, the totalizer count is automatically reset to 0 when it is read during a
scan sweep or read by remote command. It is not effected by pause scan. The totalizer
count is not reset when it is viewed with the Monitor function.
Debounce
In some applications, contacts can “bounce” when they close that results in multiple
signals on one line. Without a filter the Product detects multiple closures that can cause
duplicate counts for one closure. To filter the signal, the Product has a debounce feature
that can detect bounce on the signal and ignore it. Debounce (600 Hz) can be turned on
with the Edit channel function of the Totalizer channel (Ch402). If the debounce feature
is disabled, 10 kHz is the maximum frequency the Totalizer input can support.
