4. MODE indication light:
When the instrument is communicating with the host computer, the light will keep flashing in
random speed.
When the instrument hasn’t received signal from the host computer more than 6 seconds, the
indication light should flicker with the same light on time and light off time.
It means:
The on-off period is as long as 1.6 second means no communication and no alarm (it can be
treated as normal);
The light flashing with period 0.6 second means no communication and some general error
occurs.
The light quickly flashing with period 0.3 second means no communication and severe error
such as input over range occurs.
The light keeping off means the instrument power off or damaged; the light keep on (longer
than 8 seconds) means t
he instrument power on but damaged.
5. Setting Parameters:
(Note: x means channel number. It can be 1~4.)

bAud Baud rate
When COMM module interface is used for communication, bAud defines the
baud rate range is 300~19200bit/s.
0 ~ 19.2K bit/S
Addr
Communication
address
Every instrument in the same communication line should be assigned to
different communication address. The communication applies AIBUS
protocol. Every input channel takes one address. For example, if channel
number Cn=3 and Addr=10, then the communication address 10~12 are
assigned to the instrument.

dPtx Decimal point
dPtx is set to select display resolution for channel x
for linear inputs, the corresponding display resolution of dPt=0,1,2,3 are 0,
0.0, 0.00 and 0.000
For thermocouple inputs, when dPt=0, the display resolution is 1℃; when
dPt=1, the resolution is 0.1 .℃
Note: dPt only affects the display, and has no effect on internal data.
