Specifications

The D1000 modules feature a wide choice of user configurable options
which gives them the flexibility to operate on virtually any computer or
terminal based system. The user options include a choice of baud rate,
parity, address, and many other parameters. The particular choice of
options for a module is referred to as the setup information.
The setup information is loaded into the module using the SetUp (SU)
command. The SU command stores 4 bytes (32 bits) of setup information
into a nonvolatile memory contained in the module. Once the information is
stored, the module can be powered down indefinitely (10 years minimum)
without losing the setup data. The nonvolatile memory is implemented with
EEPROM so there are no batteries to replace.
The EEPROM has many advantages over DIP switches or jumpers normally
used for option selection. The module never has to be opened because all
of the options are selected through the communications port. This allows the
setup to be changed at any time even though the module may be located
thousands of feet away from the host computer or terminal. The setup
information stored in a module may be read back at any time using the Read
Setup command (RS).
The following options can be specified by the SetUp command:
Channel address (122 values)
Linefeeds
Parity (odd, even, none)
Baud rate (300 to 115,200)
Addressing Mode: Extended/Normal
Alarm enable/disable
Alarm momentary / latching
CJC disable (D1300 series)
RTD 3/4 wire (D1400 series)
Fahrenheit / Celsius
Echo
Communication delay (0-6 characters)
Number of displayed digits
Large-signal filter constant
Small-signal filter constant
Each of these options will be described in detail below. For a quick look-up
chart on all options, refer to Tables 5.1-4.
