4.3 SLAVE DISPLAY FOR FAD
The unit is connected in a FAD network. FAD unit(s) are scanned by a master unit which may be a
personal computer or another FDT. The slave FDT will display all data (weight and
messages) originating from the FAD with the same address.
SETUP REQUIREMENTS (9600, E, 7, 1, FAD address A)
1 Don’t care
2 Don’t care
3 3t = 03, 3b = 96, 3d = 17, 3E = 65, the rest don’t care.
Keyboard operation is normal except that no commands are transmitted to FAD’s and printing or
totalizing is inhibited. The unit may display data from any of 30 FADs in a network . the
selection is performed by Fn 01 to Fn 30 corresponding to FAD address A to Z (41h to 5Eh).
Only polled FADs are displayed, so the master in the network must have been set up to poll all
FADs, accordingly. The master may poll the addressed FAD units sequentially or in any order of
frequency. The FDT will pick up the selected FAD data and display it.
4.4
DUAL FAD MASTER MODE (SCALE A/B)
The FDT polls two FADs A and B connected to loadcell scales. The unit may display the weight
from scale (A) or from scale (B) or the sum of the two weights (A+B). Individual scale weights or
the sum of the two may be printed or totalized or transmitted to PC. If scale A or scale B is
selected the operation is normal single scale where the display and keyboard operate for this scale
only. If (A+B) is selected display and keyboard operation is similar but with few specific
limitations.
Selection of A or B or A+B is performed by key I and is indicated in the front panel by the
Annunciators L ; . (A+B)=Both illuminated.
The (A+B) mode has the following operational characteristics:
- If any of the two scales is out of range the (A+B) is out of range.
- For the “NO MOTION” condition both scales must be stable.
- For the :CENTER OF ZERO” condition both scales must be within 0,25 division.
- Switching to Net mode is supported provided both scales are in Gross or Net mode.
If any of the scales is in NET mode it will automatically be switched to GROSS mode.
- If any of the FADs displays a message instead of weight, this message will be displayed
on the FDT.
- The Fn key is not operational in (A+B) mode.
For approved scales if A+B mode is used the scales must have the same display step.
