Interfaces
J4 and J5 – Serial Port
J4 and J5 are 9 pin female D-shell (AMP 205204-4, pins AMP 66506-
3) connectors. Each connector is a serial interface that allows
communication with another ULTRA 200 Series drive, a PC, a
terminal, a host computer, a controller or an optional TouchPad. The
signals on J4 and J5 are internally connected, which allows daisy-
chain connection of several drives. The shell of the connector is
grounded to the chassis for shield termination.
The serial interface of the ULTRA 200 Series uses the standard NRZ
asynchronous serial format, and supports both the RS-232 and the
four wire RS-485 communications standards.
●
Standard baud rates include 1200, 2400, 4800, 9600 and 19200
baud. 9600 is the factory default setting.
