Laying Cables and Connecting Wires
Communication Cable
Afimilk MPC communication is of RS485 type. Communication cables should support this
type of protocol.
afimilk offers a suitable cable (part number
4097324) designated for connecting the RS485
communication port of several products to the
Computer. The cable provides 3-wire connection
and shielding for harsh electrical environments.
The cable has one twisted pair and a single
additional conductor. It also provides a drain wire
that allows easier connection of the shield. The
twisted pair of wires transmits and receives the
communication signals. The single conductor runs
the communication ground reference.
This shielded core is protected with a heavy-duty jacket.
Laying Communication Cables
Afimilk MPC communication is based on a single line “daisy chain” type connection. This
means that a single communication cable “collects” all the devices on the line to a single
Communication Port in the PC.
The example below demonstrates a 64 point parlor connection.
After laying cables, connect wires as described in the following section.
