3.5 Serial Communication Connector CN3

CN3 Terminal Layout and Identification
The servo drive can be connected to a PC or controller via a serial communication
connector. Users can operate the servo drive through PC software supplied by Delta
(contact to the dealer). The communication connector/port of Delta servo drive can
provide three common serial communication interfaces: RS-232 and RS-485
connection. RS-232 is mostly be used but is somewhat limited. The maximum cable
length for an RS-232 connection is 15 meters (50 feet). Using RS-485 interface can
allow longer distance for transmission and support multiple drives to be connected
simultaneously.

2) There are two kinds of IEEE1394 communication cables available on the market. If the user
uses one kind of cable, which its GND terminal (Pin 1) and its shielding is short-circuited,
the communication may be damaged. Never connect the case of the terminal to the ground
of this kind of communication cable.
