1290 Strain Gage Input Indicator 19
JbUS
for Jbus protocol
OFF
to disable comms
NOTE: This indicator skips steps I1 and I2 if serial communication is not implemented (set to
OFF
).
I1. SERIAL COMMUNICATION DEVICE ADDRESS
The display shows
Adr
(address) followed by a number ranging from:
1-95 for polling/selecting protocol (1-31 being valid addresses)
1-255 for modbus/jbus protocol (up to 128 devices per multidrop link)
I2. SERIAL COMMUNICATION BAUD RATE
The display shows bd (baud rate) followed by:
150
for 150 baud
300
for 300 baud
600
for 600 baud
1.20
for 1200 baud
2.40
for 2400 baud
4.80
for 4800 baud
9.60
for 9600 baud
19.2
for 19200 baud
I3. SERIAL COMMUNICATION BYTE FORMAT
The display shows
bF
(byte format) followed by:
7E
for 7 bits with even parity
70
for 7 bits with odd parity
8E
for 8 bits with even parity
80
for 8 bits with odd parity
8
for bits with no parity
NOTE: The indicator skips steps L to L3 if analog retransmission is implemented.
L. ANALOG RETRANSMISSION (Option)
The display shows
A0
(Analog Output) followed by:
0.20
for 0-20mA
4.20
for 4-20mA
0.10
for 0-10 V
OFF
for retransmission disabled
L1. ANALOG RETRANSMISSION SCALING: LOW SCALE VALUE
The display alternately shows
Ar. L.S.U.
(Analog Retransmission Low Scale Value) and a numerical
value. This parameter establishes the lower limit for the analog output; only the numerical value is
shown during modification. Resolution and decimal point position are as selected for the readout
value.
