It’s recommended that you use the RS-232 port for transferring applications.
On DTAM Plus versions with a Comm (RS-485 / RS-232) port, you can also
download applications using an RS-485 connection.

Create your own cable
To download through the RS-485 port, you must:
•
set DIP switch position SW-2 ON
•
create a communication cable. The RS-485 port connections are:
DTAM Plus Comm Port
RS-485/RS-232 Connector
Pin 1 = TX485 -
Pin 2 = Tx485 +
Pin 3 = Rx485 -
Pin 4 = Rx485 +
Upload/download functions are initiated from a personal computer running
the programming software DPS (Catalog No. 2707-NP, series H or later).
Transfer functions always occur at 9600 Baud (regardless of the DTAM Plus
application’s printer or communications port settings).
After a reset with a valid application, the DTAM Plus baud rate is set to the
parameters defined by the application program residing in the DTAM Plus.
