RS232: Serial Communication Port
An optional serial RS-232 communication port is available on the Geo Brick Drives. This port can be
used as a primary communication mean or employed as a secondary port that allows simultaneous
communication.
RS-232: D-Sub DE-9F
Mating: D-Sub DE-9M

The baud rate for the RS-232 serial port is set by variable I54. At power-up reset, The Geo Brick Drive
sets the active baud based on the setting of I54 and the CPU speed I52. Note that the baud rate frequency
is divided down from the CPU’s operational frequency. The factory default baud rate is 38400. This baud
rate will be selected automatically on re-initialization of the Geo Brick Drive, either in hardware using the
re-initialization (RESET SW) button or in software using the
$$$***
command.
To change the baud rate setting on the Geo Brick Drive, set I54 to the corresponding value of desired
frequency. Restart the software (Pewin32Pro2), and adjust to the correct baud rate in the communication
setup window. Then issue a
SAVE
and a reset (
$$$
), or recycle power on the Geo Brick Drive. For odd
baud rate settings, refer to the Turbo Software Reference Manual.
