4 SETUP AND OPERATION
5. RS-530 (DB-25) —This option configures the operating parameters for this
physical port. Select async or sync (internal clock, external clock, or siv on rx
clock).
6. RF Modulator —This option configures the operating parameters for this physical
port, as well as the IF port. The settings are Operate, Standby, CWTest, Con Test,
and Rev Test.
7. Operate causes the RF and IF ports to become active. The selected RF output
frequency will be used for the RF port. The RF frequency setting must be
between 71 MHz and 129 MHz. The Output Level has settings ranging from 1 to
40. Each increment represents 0.5 dBmV. A value of 1 is 30 dbMv and a value of
40 is 50 dBmV.
8. CWTest and Con Test are test modes. These modes are documented in the
section titled Testing the RF Modulator.
9. Rev Test mode causes a spectral inversion of both signals.
10. PID Generator— MPEG Message Generator port option.

Logical Ports Configuration
The OM 2000 supports up to 16 logical ports, designated ports 1 through 16. At
least one logical port must be an input and at least one logical port must be an
o u t p u t .
To set up a logical port, you must:
• Select the port number to configure.
• Select the physical interface associated with the port.
• Select the type of port: input or output. If you select input, you must define the
PID map. For Ethernet, you must supply the source (input port) or destination
(output port).
The OM 2000 Logical Ports Configuration window is illustrated in Figure 4-16 and
defined in Table 4-4.
