3.6.4 RS-232 port
RS-232 port lets the GF_VEDO TL dialog with RS-232 serial transmission protocol at a baud rate from 9.6 kBaud to
115 kBaud.
The RS-232 port is not optically isolated and uses a 9-pin (male) D-sub connector. Signal assignment is shown in
Table 7.

3.6.5 RS-485 port
GF_VEDO TL uses the RS-485 port to dialog according to OSI specifications at the physical level defined by stan-
dard EIA-485.
The RS-485 port is optically isolated and allows dialog from 9.6 kBaud to 115 kBaud via an RJ10 4p4c connector
(Registered Jack type 10 with 4 positions and 4 contacts).
Signal assignment is shown in Table 8.
