2.7 CONFIGURATION INSTRUCTIONS
2.7.1 FIBER OPTIC MODULE CONFIGURATION INSTRUCTIONS
Each fiber optic module must be configured (switch selectable) prior to installation. Con-
figuration options include network baud rate selection (57.6 Kbaud, 115.2 Kbaud, and 230.4
Kbaud), and network key-up selection.
Configuration Switch and Jumper locations are identified on the overview of the fiber optic
modules depicted in Figures 8, 11, and 13. Specifications detailing fiber optic module Net-
work Configuration Switch and Jumper designations for standalone, panelmount OCM and
1771 plug-in OCM fiber optic modules are provided in Tables 16, 17, 18, and 19, and for 1746
plug-in OLC and 1756 plug-in OCX fiber optic modules are provided in Tables 20 and 21.
2.7.1.1 FIBER OPTIC MODULE BAUD RATE SELECTION
Phoenix Digital’s fiber optic modules will operate at all Rockwell DH+ and RIO network
baud rates... including 57.6 Kbaud, 115.2 Kbaud, and 230.4 Kbaud. The Rockwell equip-
ment must first be configured for the desired baud rate. Then the Phoenix Digital fiber optic
modules can be switch selected to be compatible with the desired baud rate. (The Factory
Default Baud Rate for all Phoenix Digital fiber optic modules is 57.6 Kbaud.)
See Figure 8 and Tables 16 and 17 for Network Baud Rate switch definitions for standalone,
panelmount OCM and 1771 plug-in OCM fiber optic modules. See Figure 11 and Table 20 for
Network Baud Rate switch definitions for 1746 plug-in OLC and 1756 plug-in OCX fiber optic
modules.
2.7.1.2 FIBER OPTIC MODULE NETWORK KEY-UP SELECTION
Phoenix Digital’s fiber optic modules insure the highest level of data integrity possible for all DH+
and RIO data transmissions on the fiber optic network. No leading or trailing data bits are ever
lost (or chopped) using Phoenix Digital’s fiber optic modules, and data that is repeated from
module to module on the fiber optic network is always precisely synchronized to the exact timing of
the network protocol. All of this is accomplished through the use of very accurate, high speed
modulation techniques, continuously applied to every data transmission on the network.
