3.4.2 RS-485 port
The terminal 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 5.
Length and type of connection cable between GF_PROMER and GFX / GFX4 / GFX4-IR / GFXTERMO4 units:
-
standard telephone up to 10m
-
shielded cable up to 150m (shield to GND)
-
woven and shielded cable (Belden, shield to GND) for distances > 150m up to a maximum of 1200m

3.4.3 Ethernet port
The terminal uses Ethernet port to dialog via IEEE 802.3 Ethernet protocol.
The Ethernet port can dialog at 10/100 Mbps using an 8-pin RJ45 connector with LED.
We recommend an Ethernet Base-T with braided leads (CAT. 6).
The wiring scheme must conform to standard TIA/EIA-T568-A. Signal assignment is shown in Table 6.
