Channel tabs
The first six Inputs on the OL2252 module are grouped into two channels, which
correspond with and control the two pulse counters on the module. (The last two
Inputs – 6 and 7 – are generic DC inputs.) The Inputs are grouped as follows:
Channel Counter Input Hardware Reset Hardware Enable
1 Input 0 Input 2 Input 4
2 Input 1 Input 3 Input 5
These channels are configured via the Channel 1 and Channel 2 tabs. Both tabs
have the same parameters:
Frequency – The maximum frequency range for the channel to count
pulses. Available frequencies: 15 KHz (default), 10 KHz, 5 KHz, 2.5 KHz, 1
KHz.
To configure Frequency, click the to the right and select a frequency
from the pop-up menu.
Hardware Enable – Option to use value received on the Hardware
Enable input (Input 4 for Channel 1, Input 5 for Channel 2) to determine
when the channel starts and stops counting.
o If Disabled (default), then the Hardware Enable input can be
used as a generic DC input and will not have any effect on the
channel.
o If Enabled, then the value received on the Hardware Enable
input controls the corresponding channel’s behavior: a value of
ON starts counting, while a value of OFF stops counting.
To configure Hardware Enabled, click the to the right and select an
option (Disabled or Enabled) from the pop-up menu.
