25-pin D-connectors:
Table 3–2: Cables and Adapters for the DECserver 700-08
Cable
Description
BC17D Shielded Null-Modem
Cable Use this cable to connect asynchronous devices that use
modem signals.
BC22D Shielded Null-Modem
Cable Use this cable to connect asynchronous devices that use
data leads only.
BC22E or BC22F Shielded
Straight-Through Modem Cable Use either of these cables to connect asynchronous mo-
dems.
BC22R Shielded Null-Modem
Cable Use this cable to connect to non-Digital host systems,
devices using CTS/RTS flow control, and data switches
that require simulation of Ring Indicator (RI) and/or Carrier
Detect (CD) signals.
H8575-A (EIA-423-A to
EIA-232-D) Adapter Use this adapter to connect to 25-pin D-sub male connec-
tors (for example: printers).
H8575-B Adapter Use this adapter to connect to 9-pin D-sub male connec-
tors.
H8571-D (EIA-423-A to
EIA-232-D) Adapter Use this adapter to connect to 25-pin D-sub female con-
nectors.

V.24 to RS-232-C Adapter
Part No.12-27591-01
Use this adapter to convert from V.24 to RS-232-C by
eliminating the extra signals that exist in V.24. EIA-232-D
has the same signals as V.24; therefore, no adapter is
necessary.

The V.24 to RS-232-C adapter must be fitted if the modem/eliminator has Data Signal Rate
Selector (DCE) on pin 23. Failure to comply with this could result in damage to the interface
module and modem or eliminator. If you are not sure what signals the modem or eliminator
provides, contact Digital Customer Services, or fit the adapter connector as a precaution.
