Input/output panel

Three versions of the I/O panel are currently used with the Application Module. Many existing installations have application-specific I/O subpanels, as shown in Figure 27. Some installations have a universal I/O panel, as shown in Figure 28. All new installations have a generic I/O panel, shown in Figure 29.

The I/O subpanel has nine connectors: J1 through J6 are 25-pin (DB25) connectors; J7 through J9 are 9-pin (DB9) connectors. The removable I/O subpanel is connected to the Application Module by cables from transition cards in the Application Module. All connectors on the I/O subpanel are shielded from RF.

The universal I/O panel has 20 connectors, as shown in Figure 28. The Serial I/O (labeled from 1 through 32), Spare, Host, and ESDI Link ports are 25-pin (DB25) connectors; the Ethernet port is a coaxial cable connector; and the INT MODEM, SDI LINK, EXT MODEM, and SYS CONS ports are 9-pin (DB9) connectors. All connectors on the universal I/O panel are filtered.

The generic I/O panel (Figure 29) is similar to the universal I/O panel but all connectors, except one, are labeled by card and connector. For example, the connectors in the top row are labeled (from left to right) card 5 conn 3 through card 2 conn 3. The exception to this labeling convention is a 15-pin connector labeled Ethernet.
