Protective Ground

It is necessary for the receive data pin of the external device to be connected to pin 3
(transmit data pin) of the scale. Likewise, the transmit data pin of the external device
must be connected to the receive data pin (pin 2) of the scale. With certain devices
such as computers with 9 pin serial ports (DB9), pins 2 and 3 must be "crossed." That
is, pins 2 and 3 of the external device should be connected to pins 3 and 2 of the
scale respectively. Cables for this purpose are generally available from computer
equipment suppliers. Computers with 25 pin serial ports (DB25) generally require
"straight" cables to the Setra scale's RS-232 port.

Note:

The "handshake" signals, such as "busy", are not implemented. This requires
that the peripheral have a minimal buffer (15 characters). Some computers
requiring handshaking will need a connection between two pins on the
computer’s connector named DTR and DSR (Data Terminal Ready and Data
Set Ready). CTS may also need to be jumpered to RTS at your computer
interface (Clear To Send and Request To Send).

Use a mating connector (subminiature d-type, female DB9-RJ45 converter or female
DB25-RJ45 converter on the computer and male DB25-RJ45 on the scale) with a
straight through RJ45 cable to gain access to these lines. The protective ground may
be attached to other grounds as deemed appropriate. This protective ground is
available at pin 1 and is connected to the chassis of the scale.

The maximum recommended cable length is 15 meters. The cable may be longer if it
has less than 2,500 pF capacitance. The load impedance of the device connected
should be between 3,000 and 7,000 ohms with no more than 2,500 pF shunt
capacitance.

For more information, consult EIA Standard RS-232: "Interface Between Data Termi-
nal Equipment Employing Serial Data Interchange."
