Data Port (DCE)
- Pins 21 through 28 inclusive. This port is used to interface
the MHX-2400 module to a DTE device and operates at 2400 to 115,200
bps. The levels are active low 5V logic levels, and include (See
Appendix B for a complete description):

RX Indicator
- This active high output indicates the modem is receiving data
packets with correct CRC, and is designed to drive a LED. When the unit
is configured as a Slave, this LED will typically be on solid under good
operating conditions.
TX Indicator
- This active high output is designed to drive a LED, and indicates
the modem is transmitting.
Antenna Connector
- The MHX-2400 uses an end launch SMA RF
connector. Microhard Systems can provide the cabling from the
module to the appropriate antenna connector. A suitable antenna must
be used to ensure adequate performance of the MHX-2400 module.
N/C
