1.2 Serial communications connections
If more than one drive is to be connected to a serial link, make connections as shown in the diagram below.
• The serial communications cable must be shielded. The shield(s) must be connected as shown in the diagram below:
A data communications cable should not run parallel to any power cables, especially ones that connect drives to
motors. If parallel runs are unavoidable, ensure a minimum spacing of 300mm (12 in.) between the communications
cable and the power cable.
Cables crossing one another at right-angles are unlikely to give trouble. The maximum cable run length for a EIA485
link is 1,200 metres (4,000 feet).
If more than one drive is connected to the host computer, please adjust the serial address of each drive to ensure that each
drive has a unique address.
Therefore with the drive in the above condition, all commissioning and operation can be done using the EIA485
communication link.

Pin 6 TX Enable
The TX Enable pin is a 0 to 5V output from the Drive that can be used to externally control and switch the buffers on a serial
communications converter from transmit to receive and vice-versa. An example of a converter that can be used with this
signal is the Amplicon 485Fi.
