Issue these commands to configure the
RS-232
connector for use with an RP240:
PORT2
; Select the RS-232 connector (COM2) as the port affected by
; the DRPCHK1 command.
DRPCHK1 ; On power up, check for RP240 on COM2.
NOTE
: The +5VDC output on Pin 9 has short circuit protection/inrush current
protection. If you plug in the RP240 while power is applied, the protection circuit
may sense the inrush current and shut down the +5VDC output. To recover from
this condition, you may need to cycle power or reset the drive.
Configuring the Serial Ports
To control the applicable port for setting up serial communication and transmitting
ASCII text strings, use the PORT command:
PORT1
; Selects the RS-232/485 connector (COM1)
PORT2
; Selects the RS-232 connector (COM2)
The following commands can be used to configure the Gem6K serial ports and the
terminals used by Motion Planner. Complete descriptions of these commands can
be found in the
Gemini GV6K/GT6K Command Reference

The default baud rate for the Gem6K is set at 9600. The RS-232/485 connector
(COM1) only supports 9600 baud. The RS-232 connector (COM2) supports other
baud rates; see the BAUD command for more information.
•
The Gem6K’S RS-232/485 connector (COM1) contains connections for both RS-
232 and RS-485 communication. The Gem6K will automatically switch between RS-
232 and RS-485 mode depending on which connections in the port’s 9 pin D-
connector are active. See wiring diagrams. The RS-232 connector(COM2) only
supports RS-232 communication.
•
Some RS-232 cables use hardware handshake signals that are used by the RS-485
pins. The RS-485 interface will automatically disable itself if this is detected. If this
occurs, you must reset the drive to re-enable the RS-485 interface.
•
Enabling Ethernet communications (NTFEN1) will disable the RS-232/485
connector (COM1).
