The power switches to the radio with solid state FETs under software
control. Licensed radios that support long distance communication require
more power current. If the maximum current is greater than 1 A, the radio
must use an external power supply.
The control of the radio power output is a 5 V logic level signal on the flow
computer’s main board. For testing, this control signal is defined as discrete
output channel 3.
The MDS radio assembly consists of the radio (customer provided) and a
support bracket. To install the MDS radio assembly into the flow
computer enclosure, follow the steps below.
Warning
Ensure the area is non-hazardous before connecting or
disconnecting the radio.
1.
Open the enclosure door. Loosen the thumbscrews on the mounting
bracket, and lift the main board and mounting bracket up to expose the
chassis bracket.
2.
Mount the MDS radio onto the support bracket, and then secure the
assembly to the chassis bracket with the fasteners on the radio bracket.

for assembly orientation and mounting location.
3.
Connect the coaxial ground to the enclosure ground stud using the
coaxial ground hardware provided.
4.
Mount an N-type bulkhead jack or optional coaxial protector on the
bottom of the enclosure, and connect it to the radio antenna output
through a coaxial cable and N-type plug.
5.
Connect the cable assembly (p/n 3-0500-090) from the radio’s DB25P
connector to the flow computer's host port (TB16 on the main board)
or other RS232 device. Connections to TB16 are shown in the table
below.
