Communication Cards
3-8 Rev 2/01
3.4 INITIAL INSTALLATION AND SETUP
Communications card installation is normally performed at the factory when the EF-Series unit is
ordered. However, the modular design of the unit makes it easy to change hardware configurations in
the field. The following procedures assume that this is a first-time installation of a communications
card in an EF-Series unit and that the unit is currently not in service. For units currently in
service, refer to the procedures in Section 3.6, “Troubleshooting and Repair.”
CAUTION
When installing units in a hazardous area, ensure that the components selected are
labeled for use in such areas. Change components only in an area known to be non-
hazardous.
CAUTION
Be sure to use proper electrostatic handling, such as wearing a grounded wrist
strap, or components on the circuit cards may be damaged.
3.4.1 Installing Communications Cards
All communications cards install into the EF-Series unit in the same manner.
1.
Unplug the Power terminal block at P8 to ensure power is removed.
2.
Plug the communications card connector P1 into connector P3 on the Main Electronics Board.
Figure 3-4 shows the card location. Gently press the connectors together until the card contacts
a stand-off.
3.
Ensuring that the three stand-off holes in the communications card line up with the
compression stand-offs on the Main Electronics Board, firmly press the communications card
onto the stand-offs.
4.
Plug in the Power terminal block at P8 to allow power to be applied.
5.
With the EF-Series unit powered up, and a PC connected to the LOI port and running the
ROCLINK software, ensure that the configuration associated with the communications card is
correct. If not, change as needed.
6.
Perform wiring as instructed in Section 3.5.
