Before connecting the optical cable, first remove and save the plastic dust caps from the optical ports

and fiber connectors.

Remove and store the dust caps from the fiber connections. Clean the connectors with Isopropyl

alcohol on lint free tissue.

2.6.2

SPECIFIC OPTICAL CABLING

Refer to the architecture diagrams, Figures 2, 3 and 4, for help in defining the optical cabling hookup.

Note that in Local Daisy Chain mode the TX1 and RX1 ports always connect to the fibers going toward

the master controller. The TX2 and RX2 ports are always connected to the fiber going toward the trunk

and branch ends. If the unit is in master mode or either fault tolerant mode the TX1 and RX1 ports and

TX2 and RX2 ports are equals.

2.7 Electrical Cabling

2.7.1

RS232 Connections Connect both the master controller CPU and each local terminal's RS232 com port

via the DB25S RS232 port on the Model 9525A modem. The only required connections between the

terminal equipment and the modem are pins 2 (Data Input), 3 (Data Output), and 7 (Signal

Return/Common). On the modem end, however, if the Electrical Anti-streaming feature is enabled, pin

4 (RTS) must be in a high (TRUE) state in order to be able to transmit the data (input on pin 2) via the

fiber.

2.7.2

RS422 and RS485 Connections

When operation with RS422 or RS485, refer to table 5 for the pinouts. In RS422 or RS485 model there

are no RTS or CTS control lines. Rather the RTS and CTS signals are internally enabled. The RTS and

CTS indicator will always be illuminated when the unit is operated with RS422/RS485 data. Refer to

section 2.3.4, Priority Select, for an additional consideration when operating in RS485 2wire mode.
