5. Refer to Figure 6 and Table 1 for switch locations.
6. Set the address for the module using DIP switch SW1.
For remote access, each channel module in the shelf must have a distinct module
address. Valid module addresses are the numbers 1 to 36, as shown in Table 2 of
this Instruction Data Sheet. In a full-size shelf, this is usually set to the number of
the physical slot the module will occupy. (Consult your multiplexer manual for
details on using remote access and configuration features of the system.)
7. Set the position of SW2-6 to enable or disable channel 1.
Place SW2-6 in the UP position to enable channel 1. Place SW2-6 in the DOWN
position to disable channel 1.
8. Set the position of SW3-6 to enable or disable channel 2.
Place SW3-6 in the UP position to enable channel 2. Place SW3-6 in the DOWN
position to disable channel 2.
9. Set transmit/receive level switches SW4, SW5, SW7 and SW8 if settings other than factory
standard are desired.
The transmit and receive levels can be set from - 9.5dB to +9.5dB, in 0.5dB steps.
The values for these switch positions are shown in Table 3.
Switch settings are cumulative. For example, to set the level to +9dB, turn off
switch position 1 to select “+” and turn on switch positions 2 and 5 to select 9dB.
To set the level to -7.5dB, turn on switch position 1 to select “–” and turn on switch
positions 3, 4, 5, and 6 to select 7.5dB.
The switches are set at the factory to provide a transmit level of 0dB, and a receive
level of 0dB.
10. Select any unused time slot for channel 1 using SW2-1 through SW2-5.
The digitized voice signal of each RFL VF-16B module occupies one 64-Kbps
digital time slot within the multiplexer’s aggregate rate. Use the settings shown in
Table 7 to select which time slot the module uses. Consult your multiplexer manual
for guidelines on time slot selection.
