This document contains proprietary information and such information may not be disclosed

f. Connect AC input ground (green wire) to 1A6 TB3-3.
g. Connect AC low input (white wire) to 1A6 TB3-2.
h. Connect AC high input (black wire) to 1A6 TB3-1.
CAUTION
Black, white and green wiring may also be used in installations outside the United States.
Technicians must note that the black wire (equivalent to Blue) is the AC HIGH and the
white wire (equivalent to brown) is the AC LOW. This condition may not be the same as
local wiring standards, and caution must be observed when working on the AC supply
wiring. The ground wire is provided as either black for dc return path or protective ground
green/yellow.

Connecting DME Keyer Wiring
a. Verify that the primary AC power (located in the shelter main circuit breaker box), VOR equipment and
DME equipment circuit breakers are in the OFF position.
b. Using the two-conductor electrical cable and provided in the AC Power/Installation kit (Figure 11-24),
connect KEY_OUT+ and KEY_OUT- signals from the 1A9 Interface CCA located in rear of the VOR
cabinet to the appropriate location as identified in Table 9-3.

9.5.16 RCSU and RMM Connections
Note: Changes to the S2 Configuration DIP switch should be followed with a Reset (located on the 1A1 LCU).
a. If the VOR is provided with a 2238 or 2240 RCSU then connect the copper wires from the RCSU to the
1A9TB2-1 and 1A9TB2-2 locations on the Interface CCA for a Dedicated Modem connection type. For a
RF Modem/Fiber connection type, the RS232 connection should be made to the 1A9J5 DB9 connector.
DIP switch S2-1 located on the 1A3 Control Backplane CCA should be set to match the Connection Type
as well.
b. If a telephone line is available for remote maintenance monitoring (RMM), connect the tip and ring wires
from the telephone interface box to the 1A9 Interface CCA locations TB2-3 and TB2-4. Polarity is not
important. DIP switch S2-2 located on the 1A3 Control Backplane CCA should be set to “DIAL-UP”
when using this internal dial-up modem. Use the two-conductor electrical cable provided in the AC Power
Installation kit (Figure 11-24) for this connection.
c. If the VOR’s internal dial-up modem is unable to comply with local telephone requirements then connect
the telephone line to an external modem and connect the external modem serial port to the 1A9 Interface
CCA J6 connector. DIP switch S2-2 located on the 1A3 Control Backplane CCA should be set to
“~EXTERNAL” when using an external dial-up modem. DIP switch S1-6 located on the 1A3 Control
Backplane CCA controls whether the VOR station will allow remote configuration of transmitter and
monitor parameters. When set to “RMT ALLOWED” a remote user logged into Security Level 3 can put
the VOR station in Local Mode from the PMDT and change all parameters as if connected directly to the
cabinet in the shelter. When set to “~NOT ALLOWED” the system can not be put in Local Mode from the
PMDT and remote parameter changes are blocked throughout the software.
