Connection Example Between PC Serial Port and User
Port
Connections to pins 4,6,7 and 8 are required only if your software
requires hardware handshaking.
NOTE
User port cannot be used when the RS-485 module is connected.
Service Port Connection
Connection Cables
To connect to the service port, you need a suitable cable with an RJ45
connector. Depending on the connections of your PC, you can either use
the Serial Connection Cable (optional accessory 19446ZZ) or the USB-
RJ45 Serial Connection Cable (optional accessory 219685). The USB
cable enables you to connect the transmitter to a PC via a standard type A
USB port. Note that the USB cable does not enable high speed data
transfer, since the bit rate is limited by the serial interface of the service
port.
