3.6.6 CAN port
The optional CAN port lets GF_VEDO TL dialog via the serial standard (ISO 11898-1 of 2003) for the CAN (Control-
ler Area Network) field bus, also known as CAN-bus.
This protocol is specifically designed for excellent operation even in environments with strong electromagnetic
noise, and can use a balanced potential line such as an RS-485 as means of transmission.
In particular, GF_VEDO TL implements the CANOpen Layer 2 standard. The CAN port is optically isolated and
uses a 9-pin (male) D-sub connector.
Signal assignment is shown in Table 9.

GF_VEDO TL CAN port connector
The communication cable to be used depends on the type of device to be connected.
3.6.7 USB ports
GF_VEDO TL uses USB ports to dialog via USB (Universal Serial Bus) serial communication standard.
GF_VEDO TL terminals support version USB 1.1 (transmission up to 1.5 Mbit/s).
The USB port connector is type USB-A (4 pins). Signal assignment is shown in Table 10.
Voltage for VBUS is approximately +5V with maximum current of 500mA.
Signals D+ and D- refer to the two (pseudo) differential data communication lines.
