Storage for

jumper plugs
Store unused jumper plugs on position J1 of the SILC for future use. The
following are descriptions of the three options and their jumper settings.
• Normal power on the TX and RX leads. This option is set at the
factory and provides normal power (-48V or -40V) on the TX lead and
battery return (BRTN) on the RX lead to power the terminal. To
implement it, install one jumper plug across the RX and BRTN pins,
and one across the PWR and TX pins, as shown in Figure 14 on
page 64.
