The COMM’S submenu has the following options:
CHANS submenu
If you configure the 6666 or 6667 to use fewer than 6 channels (CHANS < 6), make the
following adjustments to avoid alarm or transducer failure on the inactive channels:
z
Set the Alert and Danger alarms for the inactive channels to their maximum values. See
“ALM 1-3 and ALM 4-6 submenus” on page 17.
z
Set RISING to “YES” for the inactive channels. See “ATTRIBS submenu” on page 23.
z
Set the input signal values for the inactive channels to the largest possible range. See
“TX 1-3 and TX 4-6 submenus” on page 21.
UNITS submenu
The UNITS submenu has the following options. These determine the measurement unit for
each channel.
Note: The measurement unit is set at the factory, and cannot be changed by changing the display
unit. For example, if the monitor display shows 0°C and you change the unit, the display

COMM’S
MODULE
Choose the MODBUS serial address for the monitor (1–247). The address
must be unique in the MODBUS network.
BAUD
Choose the speed for serial communications (4800, 9600, 19200, 38400).
PARITY
Choose the parity for serial communications (NONE, EVEN).
RESCALE
Choose the format for data transmission (NO, 16 BIT). Some MODBUS
masters handle data as integer numbers, not floating point format. NO
uses floating point format, while 16 BIT uses integer (unsigned) format.
SCALE
Choose the scale for 16 BIT data transmission (0–65535) if the MODBUS
master uses integer (16 BIT) numbers. This sets the value to transmit for
full scale amplitude. Use the same scale factor as the MODBUS master.
EXIT
Return to the Factory menu. The monitor remembers the current values
for menu options, but does not write them to memory until you exit the
Factory menu.
