1.2.3 G4 EX termination board

The G4 EX termination board can be accessed by removing the rear end cap (see
Figure 1–7). All user connections should be routed through the cable entry hubs
and should adhere to local codes.
Located on the termination board, the user will find connectors for two (2)
communication ports: RS-232, RS-422 or RS-485 (software selectable). The user
should also note that there is a dedicated port for RS-232 local communications.
This is a plug type port and will connect to an internal PCCU connector or an
explosion proof external PCCU connector.
For more information on the explosion proof PCCU connector, see the
corresponding section. Additionally, for the internal PCCU connector, see the
section under Optional Equipment in this chapter.
