Host Menu Description
Type Type of host communication interface. Modbus or Mark/Space.
Use F1/F2 to select.
Mark/Space Adr 4 Address of ATT on Mark/Space bus. 0-999 is valid.
Low Speed 4 Whether or not to use low speed on Mark/Space bus. Yes or No
is valid.
Xmtr to Sim 4 Type of Mark/Space transmitter to simulate. 1800 or 1900 are
valid. Use F1/F2 to select.
Encoder to Sim 4 Type of level encoder to simulate on the Mark/Space bus. Eng
Frac, Eng Dec, 0-20m , or 0-30m are valid. Use F1/F2 to select.
Disable Temp Reply 4 If 'YES' disables the temperature portion of the reply on the
Mark/Space bus and answer with only a 40 bit reply.If 'NO' the
standard 56 bit message is returned with level and
temperature. This only applies to the 1800/1900 reply mode
for compatibility. Yes or No are valid.
ASU Connected 4 If 'YES' replies with the level using a 39 bit message. The ASU is
expected to be connected to the Mark/Space bus and will add
the temperature portion of the reply to complete a 56 bit
response. Yes or No are valid.
Temp to Sim 4 Temperature units to simulate on the traditional Mark/Space
reply. F or C are valid. Use F1/F2 to select.
Offset Temp By 100 4 If 'YES' the temperature returned to the Mark/Space host is
offset by 100 degrees. This only applies to the 1800/1900

scaled integer registers. 0 - 65535 is valid.
Min Level 6 Value corresponding to a 0% scaled level value.
Max Level 6 Value corresponding to a 100% full scale level value.
Min Temp 6 Value corresponding to a 0% scaled temperature value.
Max Temp 6 Value corresponding to a 100% full scale temperature value.
