9.0 CBC RS-232 INTERFACE
The addition of the RS-232 for these scales requires the following:
Scale
Lead with 9pin d-subminiature converter
Cover with RS-232 Connector Hole cut out.
Main PCB with RS-232 parts included
The scale will have a PCB for the main parts of the electronics. These boards do not have
any parts for the RS-232 interface included. Replace the main PCB with the new one which
has the RS-232 interface included. Fit the CPU and the jumpers -taken from the earlier PCB
into the new PCB.
All parameters and Calibration including the Two Point Factory Calibration must be set before
the new PCB will be put to use for weighing.
The 3 pin connector from the RS-232 connecter goes to the main PCB. The 25 pin d-
subminiature connector is attached inside the case using the 2 hex standoffs that come with
the connector with lock-washers and nuts.
There is no special configuration or software that needs to be enabled for the interface to
operate. The manual already has all the details for the RS-232 interface in it.
INSTALLING THE RS-232 IN CBC SCALES
•
Remove the top pan and take out the
5 screws from the bottom of the scale.
2.
•
Detach the 4 cables connected with the
Load-cell, Display, Power Switch and
Battery Chamber from the main PCB.
