Heater
The HD2016R rain gauge has a temperature sensor that detects the internal temperature of the instru-
ment ( not the air temperature ). The heater is activated when the internal temperature falls below the
value set with the command CTL (default 4 °C) and is switched off when the internal temperature rises
above the value set with the command CTH (default 10 °C).
Command Reply Description
RTH address : temperature Reads the heater deactivation temperature
(default = 10.0 °C)
CTH nn.d address : & Sets the heater deactivation temperature to the value
nn.d
(activation temperature ≤ nn.d ≤ 10.0 °C)
RTL address : temperature Reads the heater activation temperature
(default = 4.0 °C)
CTL nn.d address : & Sets the heater activation temperature to the value
nn.d
(4.0 °C ≤ nn.d ≤ deactivation temperature)
RTD address : state Reads the heater enabling state:
state = Enabled ⇒ heater is used
state = Disabled ⇒ heater is not used
CTD n address : & Enables/disables the use of the heater:
n = 0 ⇒ disable ; n = 1 ⇒ enable
CHS address : state & Changes the activation state of the heater:
state = On ⇒ heater has been switched on
state = Off ⇒ heater has been switched off
Resolution of contact output
Command Reply Description
RP0 address : resolution Reads the resolution, in mm/pulse, of the contact
output (default = 0.200 mm/pulse)
CP0 n.ddd address : & Sets the resolution of the contact output to the value
n.ddd mm/pulse (max. 1 mm/pulse)
Counters reset
Command Reply Description
CS address : & Resets the partial rainfall value
CLR address : & Resets all the counters
It must be run before the total weight counter reaches
the maximum value 999,999,999 mg
RS485 settings
Command Reply Description
ROt address : state Reads the connection state of the termination resistor
of the RS485 output:
state = 0 ⇒ termination resistor not connected
state = 1 ⇒ termination resistor connected
COt n address : & Connect/disconnect the termination resistor of the
RS485 output: n = 0 ⇒ disconnect ; n = 1 ⇒ connect
RMA address : address address Reads the Modbus address (default = 1)
CMA nnn address : & Sets the Modbus address to nnn (1…247)
RMB address : baud rate index MB baud Reads the Modbus Baud Rate:
Baud rate index = 0 ⇒ 9600
Baud rate index = 1 ⇒ 19200 (default)
CMB n address : & Sets the Modbus Baud Rate of index n :
n = 0 ⇒ 9600 ; n = 1 ⇒ 19200
