5.0 Data Cards
Data cards are typically bidirectional, with some exceptions. Most data cards are interchangeable
between the remote and console module.
5.1
DIB-232 - RS-232 Interface Board
Card P/N 903-0016-00
The DIB-232 card is obsolete, and this section is for information only. RS-232 channels for new
systems can be provided by other cards, such as DIB-232-16, AIB-4 and 907-232E.
The RS-232 Data Interface Boards (DIB-232) support bidirectional RS-232 signals. DIB-232 cards may
be used at either end of the system in any available data slot. RS-232 signals are limited to 120 kbaud.
5.1.1 Input/Output
The five front panel connectors, as shown in Figure 5.1-1, are all three pin, right angle, 733 series WAGO
connectors (mate: WAGO 733-103). All five channels are separately isolated and can operate to a
maximum bit rate of 120 kbaud. All channels are protected by 250 mA fuses and transient voltage
suppression diodes. One spare fuse is provided on the board. The black dot at the top of the front panel
marks channel 1.
LED indicators are provided for each DIB-232 channel. T denotes data transmitted out of the DIB board's
front panel connection as indicated by the green LED. R denotes data received by the DIB-232 board as
indicated by the red LED.
