PANEL DESCRIPTION
DACC-1 SOCKET
DACC-2 SOCKET(w/[EXCITER] is “1”)
The following descriptions are applied when the
[EXCITER] switch is set to “1” (default).When [EX-
CITER] is set to “1&2,” [ACC-2] functions the same
as [ACC-1] above for the 2nd exciter.
ACC-1 PIN NO.

!0 EXCITER SELECTOR [EXCITER] (pgs. 7–9)
Sets the connected exciter number.
- Select [1] when 1 exciter is connected. [ACC-2] outputs
the received [ACC-1] signal to another Icom option such
as the EX-627 AUTOMATIC ANTENNA SELECTOR.
- Select [1&2] when 2 exciters or 1 exciter with 2 speci-
fied band antenna connectors is connected.
!1 INPUT ANTENNA CONNECTORS
[INPUT1]/[INPUT2] (p. 6)
Accept a 50 Ωantenna with a PL-259 connector.
