Pantalla Pvplus 700, Como Guardar Un Archivo

The 2711-NC21 and NC22 cables are 9 pin to 8 pin mini-din cables designed originally to connect a PV300 Keypad or a xxx5, xxx9 or xxx16 terminal directly to a ML1000, 1200 or 1500 processor.

They only differ by the length:

The NC21 is 16.4ft (5 meter)

The NC22 is 49 ft (15 meter)

The pinout of this cable is:

PV AIC+, ML1000

9 pin 8 pin (Rt. Angle)

DCD 1 -------- 5 DCD

TXD 2 -------- 4 RXD

RXD 3 -------- 7 TXD

GND 5 -------- 2 GND

4 ---|

6 ---|

RTS 7 -------- 3 RTS ; RTS/CTS are not crossed. They must be crossed when used with a Belden network.

CTS 8 -------- 6 CTS

Problem:

The problem is when the NC21/NC22 is connected to an AIC+ and a Belden cable is also connected. The handshaking pins are required in this setup and the handshaking pins not crossed. They are required to be crossed for handshaking to occur with the Belden cable.

If Belden is not used, the handshaking pins are not required.

Alternatives:

Use a 1761-CBL-PM02 or a 2711-CBL-PM05 with a null modem adapter.

Or, add a 9 to 9 pin adapter to the NC21 cable with pins 7 and 8 crossed. But don't re-cross pins 2 and 3, they are already crossed. Cuando es un cable 1761-CBL-PM02, SER. C PC TO MICROLOGIX COMMS. CABLE, no hay que cruzar los pines 7 y 8 sino los pines 2 y 3 en el cable adaptador, que consiste en dos conectores DB9 uno macho y uno hembra.

May 2002: New cables that correct the handshaking pins are available as Ser A Rev B.

The new pinout of this cable is:

PV AIC+, ML1000

9 pin 8 pin (Rt. Angle)

DCD 1 -------- 5 DCD

TXD 2 -------- 4 RXD

RXD 3 -------- 7 TXD

GND 5 -------- 2 GND

RTS 7 -------- 6 CTS ; RTS/CTS are now crossed with a Ser A Rev B cable.

CTS 8 -------- 3 RTS
