The TE 401-T keyboard unit has 40 buttons and 40 LEDs These buttons are read by the
software and can then be used for any desired function. The LEDs indicate the operating
status.
4 external switching elements can also be added.

Interface
General
The connection to the display unit is made over the CAN bus, which has the +24 V supply
integrated. An additional power supply connection is therefore not required.

CAN BUS Setup
This section explains how to configure a CAN bus correctly. The following parameters must
first be set: Station number and data transfer rate.
CAN bus station number
Each CAN bus station is assigned its own station number (can be set from 0 to 15) With this
station number, data can be exchanged with other stations connected to the bus. Up to 16
stations can be installed in a CAN bus system. In a CAN bus system however, each station
number can only be assigned once.

CAN Bus Transfer Rate
Various data transfer rates (baud rates) can be set on the CAN bus. The longer the bus line
is, the lower the data transfer rate that must be selected.

These values are valid for the following cable: 120 Ω, Twisted Pair.
Note: For the CAN bus protocol: 1 kbit/s = 1 kBaud
CAN Bus Termination
In a CAN bus system, both end modules must be terminated. This is necessary to avoid
transmission errors caused by reflections in the line.

CAN bus connection
A switchable line termination is already built into the keyboard unit. If this unit is an endmodule, SW8 on the DIP-switch must be set.

To ensure error-free function of the display, the blade terminal on the back must be
connected to the earth bus.

PS/2-Keyboard (not used)
Machine keyboard initialization
Machine buttons
LED control
Display detection and settings
Items 1 and 5:
The following CAN objects are reserved for the PS / 2 keyboard area and display detection:
040 hex to 08F hex
Through the different station numbers, 16 independent terminals can be operated in one
system. The station numbers are set using the DIP-Switch on the back. In addition, one
terminal must be defined as a master, which answers global objects (e.g. NumLock or
CapsLock).
Since there are a limited number of objects available in the CAN controller (max. 14
standard objects), the machine buttons are limited to 2 objects.
Items 2, 3 and 4:
