Note For more detailed information about timing, see Chapter 20, “Security Reference.” To set up
system timing, see the “NTP-G53 Set Up Timing” procedure on page 6-4.
Step 2 Return to your originating procedure (NTP).
DLP-G25 Install LAN Wires on the Backplane (ANSI Only)
Note Rather than using the LAN wires, you can use the LAN connection port on the TCC2/TCC2P if
preferred. Use either the backplane connection or the TCC2/TCC2P front connection. You cannot use
the LAN backplane pins and the LAN connection port on the TCC2/TCC2P simultaneously; however, it
is possible for you to make a direct connection from a computer to the LAN connection port on the
TCC2/TCC2P while the LAN backplane pins are in use as long as the computer that is connected directly
to the TCC2/TCC2P is not connected to a LAN.
Step 1 Using #22 or #24 AWG (0.51 mm² or 0.64 mm²) wire or CAT-5 UTP Ethernet cable, wrap the wires on
the appropriate wire-wrap pins according to local site practice.
Caution Cross talk might result if both receive (Rx) and transmit (Tx) pins connect on the same twisted pair of
wires from the CAT-5 cable. The two Tx pins need to be on one twisted pair, and the two Rx pins need
to be on another twisted pair.
A frame ground pin is located beneath each pin field (FG2 for the LAN pin field). Wrap the ground shield
of the LAN interface cable to the frame ground pin. Table 1-7 shows the LAN pin assignments.
