ast_send_event -1 e_reconnect

7.1 Advanced IP Commands

Each device has three possible modes of establishing an IP address: autoip, dhcp,
and static.

1. AutoIP is the default mode and it will always automatically assign available IP
addresses in the private IP domain 169.254.xxx.xxx

NOTE: The MediaCento IPX uses the Avahi zeroconf protocol to find an available IP

in the 169.254.xxx.xxx range.

877-877-BBOX (2269) | BlackBox.com Page 35

Chapter 7: Command-Line Interface

2. DHCP client gets an address from the local DHCP server.

CAUTION: Make sure a DHCP client is connected or problems will occur.

3. Static allows you to manually change the IP address and netmask of the device.
This requires further input before reboot.

To change the IP mode, type in:

astparam s ip_mode <mode> (where <mode> is autoip, dhcp, or static)

astparam save (saves changes)

reboot (reboots the device)

If static is selected, the following commands are needed before reboot. Type in:

astparam s ipaddr xxx.xxx.xxx.xxx (enter IP address for x’s)

astparam s netmask xxx.xxx.xxx.xxx (enter netmast for x’s)

astparam save (saves changes)

reboot

7.3 Serial Extension

Serial extension can be done from one transmitter to all linked receivers. Telnet serial
extension is also available as a replacement of serial. Serial extension information:

Default baud rate: 9600 (unless changed manually)

Data bits: 8

Parity: Even

Stop bits: 1

Flow control: None

NOTE: This is a two-way communication. The transmitter will receive any data sent

from the serial devices connected to the receivers.

Figure 7-4. Options controlling local serial lines.

877-877-BBOX (2269) | BlackBox.com Page 39

Chapter 7: Command-Line Interface

For both transmitter and receiver units, the added RJ-11 to DB9 serial cable needs to
be connected to the second serial port on the devices.

7.4 Telnet Extension

Telnet serial extension allows for serial output from a receiver through a Telnet
connection. This disables serial input coming from a transmitter but allows for 2-way
communication to specific devices.

NOTE: Telnet extension needs serial extension setting changed to “Type 2 guest

mode” in the Web interface. For details, contact Black Box Technical Support
at 724-746-5500 or [e-mail].

To set up a Telnet extension:

1. Using a Telnet protocol, use Port 6752.
