Mini-Convectron Module with RS-485
Instruction Manual - 275545
RL
Read setpoint 1 trip point
Example:
From host:
#01RL-CR
From Mini-Convectron:
*
01-9.80E-02 CR
Notes:
RL+ reads setpoint ON value, RL- reads setpoint OFF value. Same function
as RH for setpoint 1.
VER
Read Mini-Convectron firmware version
Example:
From host:
#01VER CR
From Mini-Convectron:
*
01_12997-00
Notes:
In this example, 12997 is the Granville-Phillips internal part number, 00 is
the revision. Larger revision numbers indicate newer versions of firmware.
FAC
Set factory default
Example:
From host:
#01FAC CR
From Mini-Convectron:
*01_PROGM_OK CR
Notes:
This can be used when a Mini-Convectron is not responding properly.
Cycle power or send RST after doing this function. FAC will cause default
communication and transducer parameters to be programmed:
• Base Address = 01
• Zero and span are set to default values
• A/D sample frequency is set to 60 Hz
• Baud rate = 19200
• Data format = 8 bits, no parity, 1 stop bit
SB
Set baud rate
Example:
From host:
#01SB2400 CR
From Mini-Convectron:
*01_PROGM_OK CR
Notes:
Will continue to operate at old baud rate until power is cycled or RST
command is sent. Max. baud rate is 38.4K. If you set baud rate to an odd
value like 2234, it will actually operate at that non-standard speed. Be
careful, you may need to set the program jumper if the unit stops
responding.
