53SU6000 INSTALLATION AND SETUP GUIDE
14 Introduction
Datalink network.
• If the computer contains MicroLink SUPERVISOR cards, each card can be connected to a
MicroLink peer-to-peer network. If each standard MicroLink SUPERVISOR card is paired with
a Redundant MicroLink SUPERVISOR card, the computer can communicate with one or two
redundant MicroLink networks.
3.4.3.1 Connecting to a Single 53MC5000 Controller
To connect a COM port on the computer to a single 53MC5000 all you need are:
• an available COM port on the computer
• a cable to connect the COM port with the mini-DIN configuration port on the front of the
controller (behind the flip-down door below the display).
An appropriate cable is P/N 698B184U01. Six feet (1.8 m) in length, the cable has a DIN connector on one
end and a 9-pin connector on the other.
If your COM port requires a 25-pin connector, you have either of two options:
• buy an adapter locally to use the 9-pin cable
• order cable P/N 698B183U01; it has a 25-pin connector instead of a 9-pin
3.4.3.2 Connecting a COM Port to a Datalink
A COM port on the computer can be connected to a Datalink network using a special Interface Terminal
Board (ITB) (P/N 686B720U01) that converts the RS-232 signals used by the computer’s COM port to the
RS-485 signals used by the Datalink instruments.
This connection scheme is illustrated in Figure 3-8 . Note that this drawing shows how to connect the spe-
cial RS-232/RS-485 ITB to the first 53MC5000 on the Datalink (both standard rear terminal block and
optional cord set rear connection are shown). For details concerning the rest of the Datalink (which is
essentially a “daisy chain” of instruments), its termination, and suitable wire, consult the installation section
of the 53MC5000 instruction bulletin.
Note that Figure 3-8 shows a cable used to connect the ITB with a 53MC5000 having the cord set option.
This cable is available in many lengths; the part numbers are shown in Table 6-4 .
3.4.3.3 Connecting the 53SU6000 to the Datalink Network
Once a Datalink SUPERVISOR card is installed in the computer, connect the computer to the Datalink net-
work.
If your controllers have standard rear terminal connections, making this connection requires only one
cable. This cable has a 10-pin connector with a grounding lug on one end and five bare wires on the other.
Cables may be ordered using the part numbers shown in Table 2 in
Figure 3-9 .
Making this connection if your controllers are equipped for optional rear cord sets requires:
• A cable from Table 2 in Figure 3-9
• The Communications ITB 686B622U01
• A modular cable 677B943Uxx; this cable has a modular telephone connector on each end.
(See Table 1 in
Figure 3-9 for part numbers and available cable lengths.)
To make the connection:
1. Plug the 10-pin connector on the cable to the port at the top of the SUPERVISOR card.
