STEP 4:
Slide the SIM Chip Reader’s plastic bracket in the direction indicated by the arrow and lift up the
bracket. Place the SIM chip (facing down) into the SIM bracket as shown in picture below. There is a small
cut-off on one of the corners of the SIM chip. Make sure that the cut-off is pointing upward which should
align the SIM chip with the SIM Chip Reader. Lower the bracket and lock the SIM bracket by sliding in the
reverse direction.
STEP 5:
Connect a DTE (data terminal equipment such as a computer, laptop, a microcontroller, etc.) to the
modem DB25 port using either the RS232/data cable model HRC-24-7X, the USB/data cable model HRC-24-
7XU, the DB25 data kit model HRC-24-8X or the USB data kit model HRC-24-8XU. All these models can be
purchased separately from NAL Research. The HRC-24-7X cable consists of a full DB-9 serial connector and
two terminal leads for DC power input. The HRC-24-7XU consists of a USB connector and two terminal leads
for DC power input. The HRC-24-8X data kit consists of a full DB-9 serial connector/cable, an RJ-45 for the
DPL audio handset and a DC power plug. The HRC-24-8XU data kit consists of a USB connector/cable, an
RJ-45 for the DPL audio handset and a DC power plug. Three-wire (TX, RX and GND) serial cable can also be
used (see document TN2009-25-V1.0) if flow control is not required. The A3LA-XM will automatically adjust
to the DTE baud rate.
STEP 6:
Connect an external antenna to the A3LA-XM. Any of the four types of antennas offered by NAL
Research is appropriate. Make sure the antenna has full view of the sky and the cable loss between the
modem and antenna is less than 2 dB.
