Note: Each fault code will have a corresponding bit (b0~b7). Two or more faults may
happen at the same time. 0 means normal and 1 means having a fault.
C R # 3 1 :
RS-485 communication address setting
The settings of RS-485 communication address. Range: 01 ~ 255. Default = K1. This setting
is only valid for RS-485 communication and will be invalid when connected to an ELC
controller.
C R # 3 2 :
Communication speed (baud rate) setting
The interface settings for the RS-485 communications: data rate: 4,800, 9,600, 19,200,
38,400, 57,600 and 115,200bps (bits per second). Default = H’0002.
b0 = 1:
4,800 bps
b1 = 1:
9,600 bps (default)
b2 = 1:
19,200 bps
b3 = 1:
38,400 bps
b4 = 1:
57,600 bps
b5 = 1:
115,200 bps
b6 ~ b13:
Reserved
b14:
High/low byte exchange of CRC checksum (only valid in RTU mode)
b15:
Switch between ASCII/RTU mode. 0: ASCII (default); 1: RTU. ASCII data
format: 7-bit, Even, 1 stop bit (7, E, 1); RTU data format: 8-bit, Even, 1 stop
bit (8, E, 1). This setting is only valid for RS-485 communication and will be
invalid when connected to an ELC controller.
C R # 3 3 :
Returning to default settings and OFFSET/GAIN tuning authorization
For authorization to modify the OFFSET/GAIN values.. Default setting = H’0000. CH1
example:
1. When b0 = 0, the user is allowed to modify CR#18 (OFFSET) and CR#24 (GAIN) of CH1.
When b0 = 1, the user is not allowed to modify CR#18 (OFFSET) and CR#24 (GAIN) of
CH1.
2. b1 represents whether the OFFSET/GAIN tuning registers are latched. b1 = 0:
OFFSET/GAIN tuning registers are latched; b1 = 1: OFFSET/GAIN tuning registers are
not latched. This function is only valid when in RS-485 communication mode, i.e. when
not connected to an ELC controller.
3. When b2 = 1, all settings will return to default values except for CR#31 and CR#32.
C R # 3 4 :
Firmware version
Displays the current firmware version in hex, e.g. version V1.00 is shown as H’0100.
