Installation
MAP27 Dual Channel Control Card Configuration
The MAP27 Wireless Control Card must be configured before installing it in the Series
4000 system. The card has four switches for each of the two channels. The switches are
located at the bottom of the legend plate under the label “Config.” Use the values shown in
Table 47 to configure the card.
Table 47: Channel Options
Switches 1 and 5 (
BTI
) should always be set to the
ON
position to allow the console to
perform a 'Software Controlled PTT' of the attached radio or radio gateway. If either is set
to the
OFF
position, then the PTT action is controlled through hardware.
Switches 2 and 6 (
OPT
upper) should always be set to the
OFF
position so that the
console operator can perform a transmit (TX) action on the applicable channel through the
attached radio or radio gateway. If either of these switches are set to the
ON
position, then
the channel is not allowed to transmit when the channel has a CALL indication in its
channel box icon display.
Switches 3 and 7 (
OPT
lower) should be set to the
ON
position only when the applicable
S4000 Channel is being connected to a Tait (MPT Radio) Gateway. These switches should
be set to the
OFF
position in all other cases.
Switches 4 and 8 (
FD
) should be set to the
ON
position so that the card operates in the
Full - Duplex mode, thus allowing the operator to hear the GATT (Go - Ahead - To - Talk)
tone when the radio has acquired the trunked channel for transmission. Each of the
switches may be placed into the OFF position so that all of the console positions can hear
the intercom call audio from other console positions.
