responds. The last resort is to set the module to Default Mode where the
baud rate is always 300.
Setting a string of RS-232C modules to a new baud rate requires special
consideration. Refer to Chapter 3 for instructions.

Byte 3
This byte contains the setup information for several seldom-used options.
The default value for this byte is ‘01’.
Alarm Enable
Bit 7 determines if the outputs from the LO and HI alarms are connected to
module terminal block. If the value is ‘0’ the alarms are not connected to the
terminal block. In this condition the outputs are controlled by the Digital
Output (DO) command. If bit 7 is ‘1’ the alarms are connected to the terminal
block. This bit is also controlled by the Enable Alarms (EA) command which
sets the bit to ‘1’. The Disable Alarms (DA) command clears the bit to ‘0’.
Low Alarm Latch
Bit 6 determines whether the LO Alarm is latching or momentary. A ‘1’
indicates that the alarm is latching; ‘0’ indicates a momentary alarm. Bit 6 is
also controlled by the LO Alarm (LO) command.
