A.2. External Connectors
A.2.1. Antenna Connector
J2 is Antenna Input / Output Connector: MMCX RIGHT ANGLE PCB JACK, AMPHENOL P/N
908-24100.
A.2.2. User Ports’ Connector
The user ports’ connector is used to provide connection with an external DTE or with the PC
running AWLaunch management software applications.
Note:
The RS232-to-TTL adapter must be used to provide physical level compatibility between COM
port of PC running AWLaunch and AW400Tx user interface port.
AW400Tx in PCB mounted enclosure uses 16-Lead Header Connector, ECS Corp. P/N 9616-D1-
01-03.

Control line can be used as a backup
method for entering Command
mode:
(0V) – Maintenance Mode; (3.3V)
– Data Mode
An internal 100K pull-up enables
Data Mode if this signal is left
unconnected. Maintenance Mode is
also accessible by transmitting an
escape sequence.
