3.4.3 Data I/O Interface Connector (J8)
The DATA I/O interface connector conducts data input and output signals to and from the
modem and connects to the customer’s terrestrial equipment, breakout panel, or protection
switch. The modem is currently available with a choice of four DATA I/O connectors, as
follows:
! 25-pin D connector (EIA-530) is the standard connector shipped with a base
platform modem.
! 50-pin D connector (EFData Proprietary) is the standard connector when the
modem is ordered with the optional overhead PCB or if the overhead PCB has
been installed in the field.
! 37-pin D is an alternate connector (EIA-449) available upon special request for
the base platform modem.
! 34-pin Winchester is an alternate connector (V.35) available upon special
request for the base platform modem.
The DATA I/O pinout is different for each of the interface configurations. For pinout
information, refer to the appropriate table as follows:
Standard 25-pin D connector Table 3-4
Optional 50-pin D connector Table 3-5
