THE NETWORK INTERFACES
A TLX48 uses up to three IP addresses. The Primary Control Card uses address X and address X+100.
The Secondary Control Card uses address X+1 and will take over address X in the event of a failure in the
Primary Control Card. These addresses are set by an external DIP switch. (See:
TLX48 DIP Switch
Settings , page 16.)
The primary’s IP address can be set from 15 to 45.
The default subnet used by the
TLX48 is 192.168.13.xxx. The user may use their own subnet by reconfiguring the switch
’s network
startup.
This procedure is detailed in :
How_To_Change_A_TLX_Matrix_Switch’s_IP_Address.pdf
The TLX48 uses several network ports for control and status. Port 17567 accepts commands to control
the switch.
The command API is described in the manual : TLX_Matrix_Switch_ASCII_API_V5.pdf
There are other ports that can be read to access system configuration and operating data. The actual data
format varies by model and is described in the following sections. There are five blocks of data available
for reading.
These ports are documented in the manual: TLX_Switch_Interfaces.pdf
1. Switch connection status (broadcast over port 17564 every few seconds)

The primary CPU IP address

Upper or Lower chassis flag

First port number in this block

Last port number in this block

'N' port number values
2. Port settings (UDP port 17565, TLX48 localhost only)

Port output level value

Port input enable status

Input port number (big-endian format)
3. Hardware sensor status (TCP port 17566)

Reserved for future use.
4. Alarm, Inventory and Power Supply Status (TCP port 17600)

State of the alarm contacts

Card Inventory

Power Supply Status (internal TL use only)

Switch card temperature readings
5. I/O card data (TCP ports 17601 through 17640, 1 port per I/O card)

SFP installed bits

SFP TxDisable bits

SFP TxFault bits

SFP LOS bits

I/O card type

I/O card temperature

SFP serial ID data

SFP Diagnostic data
6. Service Request (LOS) Signaling (UDP port 17560)
The TLX48 can broadcast a message over the network when a remote receiver requests attention. When
enabled, the receiver will toggle its TX pin, causing a LOS (loss of signal) event to occur at the Switch.
When detected, the TLX48 broadcasts an 'Attention Request' message over the network. This message
contains the IP address of the TLX48 and the port number that detected the request. It is left up to an
external system to detect, decode and act upon this request.

32-bits, TLX48's primary IP address

16-bits, 0 for the Upper (or only) Switch chassis, 1 for the Lower Switch chassis (in some models)

16-bits, port number (list starts from 1, not 0)

16-bits, key code in bits 0
– 7, 0x00 and 0xff are ignored
