The digital output is an RS-485 2 wire communication port. It has a fixed baud
rate of 9600 baud, half duplex and is addressable. When this card is installed, the
Hawk 3 senses the card and opens the menu choices available to the card. For
detailed command sets and communication configuration, please refer to RS-485
Communications, section 7 of this manual.
The analog output is a current or voltage that represents an equivalent range
of signal on the input. Analog output can be purchased as 4-20mADC out or
0-10V DC out. When installed, the Hawk 3 senses the card and opens the menu
choices available to the card.
6.7.1 Setting the Limits (LIM)
The ends of the analog output range (4 & 20 or 0 & 10) can be set or ‘pegged’
anywhere within the displayed value of the meter.
Example 1: The Hawk 3 is purchased as a standard 200 volt meter. The analog
output is configured by default , HI=100.0 and LO=0. When the display reaches
100 volts, the analog output will be 20mA. When the display reaches 0 volts the
analog output will be 4mA. In order to change the analog output to 20mA at 200
volts change the “HI” to 200.0
Example 2: The Hawk 3 is purchased as a process meter 4-20 mA input which
displays 0-100 percent. The analog output is configured, by default, for HI=100.0
and LO=0. When the display reaches 100 percent the analog output will be 20
mA. (Because the meter is a process meter, the input should be 20mA.) When the
display reaches 0 percent the analog output will be 4mA.
The limits can be moved or reversed (HI=0 and LO= 80.0). In this case when the
display reads “

”, the analog output will be 20mA and when the display reads“

”,
the analog output will be 4mA.
