-
PCees and
compatibles with DB25P serial comports
Definitions in the
RS232 signal table reflect pin connections for both DB9 and DB25, EIA
Standard RS232''C'' signals. The PC is considered the ''Data Terminal
Equipment'' (DTE), while a TNC or MoDem is identified as ''Data
Communications Equipment'' (DCE).
- PCees and
compatibles with DB9P serial comports
Arrows indicate the
direction of RS232C data/signal flow between the PC (DTE) and attached
serial device (DCE).
- 9 PIN serial port to 25 PIN serial adapter.
This adapter will interface the late model PCees (DTE) with
DB9P serial ports to data communications equipment comports (DCE).
- DB25S, Parallel or commonly known as the
(LPT) printer port of the PC and compatible.
The mating
connector and cable is a DB25P, and is termated at the printer end with
the Centronics male connector. CLICK HERE for a view facing the printer
connector end of the ccable.
- Universal Serial Bus (USB).
The
mating connector and cable is also shown in this illustration. The
''USB'' port was a joint venture development by Compaq, Digital
Equipment Corp, IBM PC Co., Intel, Microsoft, NEC and Northern
Telecom..
- The ''Centronics'' end of the printer or
parallel port cable.
The mating connector at the PC is a
DB25P, the connector shown in this drawing is on the printer. This
connector is called a ''Centronics'' 36 pin, female printer port.
- DB9S to DB25S, NULL-MoDem cable.
This cable may be used between computers with different
comports (DB9P and/or DB25P), or other DTE to DTE devices with serial
DB9P and DB25P comports.
- DB9S to DB9S, NULL-MoDem cable.
This cable may be used between computers with same type
comports (DB9P to DB9P), or other DTE to DTE devices with serial DB9P
and DB9P comports.
- Macintosh
512 KE Serial port.. and early Macintosh
Mac 512KE and early
model with DB9S (female) to DB9P, serial equipment or mouse cable.
- DB15S PC and Compatible ''GamePort.''
Some devices use the game port for other data I/O purposes.
The Joy-Stick cable end is a DB15P (male) connector.
- DB9P ATARI ''GamePort.''
Some
devices (including TNCees) sometime use the ATARI game port as a data
I/O port. The Joy-Stick cable end is a DB9S (female) connector.
- PC Keyboard, 5 Pin DIN (female) port.
I've included a three dimensional view of the 5 pin DIN
(male) connector at the end of the keyboard I/O cable.
- PS/2,six (6) pin Mini-DIN keyboard port.
This is the connector type now employed on late model PC
keyboard I/O ports. The 6 pin Mini-DIN is a connector resulting from an
ISO-9000 agreement.
- This adapter will enable you to use a
keyboard with a 6 pin Mini-DIN connector to a computer with a 5 pin DIN
connector.
Most late model keyboards use the PS/2, six (6)
pin Mini-DIN connector. This adapter mates the 6 pin Mini-DIN to the
older 5 pin DIN keyboard port.
- This adapter will enable you to use a
keyboard with a 5 pin DIN connector to a computer with a 6 pin Mini-DIN
connector.
This adapter mates the 5 pin DIN to the late
model 6 pin Mini-DIN computer keyboard port.
- PS/2 to Serial Mouse Adapter.
This adapter will enable you to use a mouse with a 6 pin
Mini-DIN (PS/2) connector to a computer with a 9 pin DB9P Serial
connector.
- Serial to PS/2 Mouse Adapter
This adapter will enable the use of a mouse with a 9 pin
DB9P Serial connector to a computer with a 6 pin Mini-DIN (PS/2)
connector.
- LapLink Centronics Parallel port adapter.
This adapter enables the use a standard printer (Centronics
connector), as an interface for ''LapLink'' between computers.
- The PC VGA high-density, 15 pin Video Card
I/O .
Don't confuse this ''High-Density'' D-SUB, 15 pin
connector with the standard DB15P/S.

now used as an ISO ''standard'' connector for Radio transceiver Data I/O
port.
.
- Wanna Build a ''wireline'' LAN. You'll need
this 10-Base ''T'' RJ45 connector configuration.
The same
connector configuration and pin ID is employed for both 10Base-T and
100Base-TX.
