The jumpers W1 and W2 function as a pair to configure the gang-in port. Refer to table 3.2.3 for the GANG-IN port
pin assignment. Connect to TXD and RXD to support RS-232 serial communications, or connect to V+ and V-
through 1 K ohm resistors to control the system control input with a remote toggle switch. Note that the serial port
is required for setup of the network parameters.

* Factory Default Setting
Jumpers W4 and W5 function as a pair to configure the input port source. It should not be necessary to change these
jumpers from their factory set positions. These jumpers configure the source for communications to the internal
processor on the Controller Card.
The 8-position dipswitch SW2 on the Controller Card is used to define the Controller Card’s address. Switch
position 1 is the least significant bit, and position 8 is the most significant bit. Set each switch position ON (as
marked) for a '0', and OFF for a '1'. Address 1 for example, would be DIP position 1 OFF, and positions 2-8 ON.
Controller Card addresses may be repeated within the Auto Bypass Switch chassis since each controller card has it’s
own set of interface connectors and unique IP address. However, the user may find that setting each controller card
to a unique value helps to eliminate confusion. Address “00” is reserved and must not be used.
3.4 TCP/IP and Auto Bypass Configuration
Once the user configurable jumpers and DIP switch settings inside the 2U Auto Bypass Switch are configured, there
are several parameters related to TCP/IP operations and the auto bypass and auto recovery functions that must be
initially configured in order to operate the 2U Auto Bypass Switch. These parameters are accessible using either the
serial RS232 remote control interface or the Ethernet remote control interface. These parameters include:
•
IP address, subnet mask, and gateway address for the Ethernet remote control interface on the 2U Auto
Bypass Switch (this interface also functions as the internal Ethernet node that acts as the “PING source”
used by the auto bypass and auto recovery switching functions). Note that the default values for these
parameters are 192.168.1.30, 255.255.255.0, and 192.168.1.1 respectively.
