How to console into a Netcrypt?

There are a few ways to connect to the craft port of the Netcrypt. The easiest way is to use a rollover cable (a flat RJ-45 terminated cable, pins reversed at each end) with a standard Sun chrome RJ-45 to DE-9 adapter. The baby blue Cisco DE-9 to RJ-45 cable will not work.

We've had problems connecting to Netcrypts in the field when using a Cisco terminal server, these were resolved by using the following pin out. You need to construct a custom RJ-45 to DE-9 adapter, and connect to it with a straight through (standard Ethernet) cable.

RJ45 (NC)

Serial (TSV)

1 (OR/W)

8

2 (OR)

7 (short to 2)

3 (GN/W)

6

4 (BL)

5

5 (BL/W)

4

6 (GN)

3

7 (BR/W)

2 (short to 7)

8 (BR)

- You can use Hyper Term or Putty

-- Use COM 7 (Verify COM port in Windows Device Manager)

- Connected to Netcrypt:

-- We used a USB-to-serial adaptor:

-- a Female DB9 to Female RJ45, to the USB Adaptor 

-- and connected to the "Host" port of the Netcrypt

Speed (baud): 9600

Data bits: 8

Stop bits: 1

Parity: None

Flow Control: Xon/Xoff
