SET SP1 OFF and SET SP2 OFF
[Factory default = 200
mTORR]
These setpoints correspond to the pressures at which the relays
will turn of (de-energize). The relays will turn off when the pres-
sure is above the programmed pressure value. If you are unable
to decrease the values of SP1 OFF or SP2 OFF, you must first
go to SP1 ON or SP2 ON and decrease those values to a num-
ber lower than the values of SP1 OFF or SP2 OFF you are trying
to set.
RS485 ADDR
[Factory default = 1]
This is the lower nibble of the one byte RS485 device address.
Assuming the address offset (ADDR OFFSET) is equal to 0, set-
ting the ADDR to a 5 will make the address be 0x05 in hexadeci-
mal. A 15 will set the ADDR to 0x0F in hexadecimal. Note that
the address (ADDR) must be used even when sending RS232
commands.
RS485 OFFSET
[Factory default = 0]
This is the upper nibble of the one byte RS485 address. Assum-
ing the address (ADDR) is 0, setting the address offset (ADDR
OFFSET) to a 5 will make the address be 0x50 hexadecimal.
Setting the address offset to 15 will make the device address be
0xF0 hexadecimal.
