Furthermore, the 2nd Generation DAQ's have 10 input channels, in place of the 8
or 4 channels on the older EL737 Counterboxes.
## Breaking Changes
* From version `0.5.0`, all device startup scripts assume that a low rate is
communicated by bit 2 of the status being set to 1. Beforehand, when using
daq\_2nd\_gen.cmd, the default was 0. So if you are using this script, you
might need to now additionally set the variable **RATE_OKAY_BIT** to 1, to
correct for this change, if you see a low rate warning in Nicos, when the
rate is above the configured threshold.
## How to Use
Unless a custom database is needed, a device can be configure simply by setting
