Setting Up Your MultiFRAD

If V.35 electrical interface signaling is required on the data port but a PC with EIA-232D signaling is

being used to configure the MultiFRAD, the unit has to be configured before you change to V.35

signaling. You need to set the DIP-switches, make the proper cable connections, configure the unit,

and then change to V.35 signaling on the data port.

1. Ensure that the DIP switch settings on the side of the unit are set for a command mode of

operation (i.e., Switch 1 is DOWN, Switches 2, 3 and 4 are UP).

2. Connect the external power transformer to the MultiFRAD and plug it into a live AC outlet. The

MultiFRAD does not have a power switch. When power is applied to the unit, it takes about 10

seconds for it to power-up.
