Setup and Installation
13. In the
Digital Output Panel
under
Channels
, click on the output
channel to test (channel
0
in this example) as shown in Figure 3-9.
Figure 3-9. Configuring channel 0 for output bit pattern B
14. In the
Digital Output Panel
under
Output Bits
, set the bits of
channel
0
for bit pattern B as shown in Figure 3-9.
15. Measure the voltage between signal ground and each bit of the
output port with a DMM or DVM. Make measurements at the
STA-50 terminals or the cabled mating connector that is connected
to the selected CONN-3160-D1 50-pin connector.
16. Again, each bit set to ON in the
AIO Panel
should output a logic-
high signal at the corresponding I/O terminal, reading typically
about 4 volts (minimum of 2.2 volts) at a DMM/DVM. Each bit set
to OFF in the
AIO Panel
should output a logic-low signal at the
corresponding I/O terminal, reading typically about 0 volts
(maximum of 0.8 volts) at a DMM/DVM.
Note:
The typical values shown are valid for boards with TTL
compatible outputs. For boards with relay outputs (REL-16, PDISO-8,
and PIO-32) the output will be a relay contact closure. For boards with
open collector outputs (PIO-HV) use a pull up resistor to an appropriate
voltage to detect output state. Refer to the hardware description in this
user’s guide for more details on the output’s electrical specification.
●
If the bit patterns set on the
AIO Panel
do not agree with the
logic levels measured at the I/O terminals, the board is not
functioning properly. Stop here, and determine why.
