7.5 Cabling
Maxon provides a variety of accessories (see Section 8.4) which we recommend are used to interface
to the data modem.
The CA8360 interfaces the power and DTR line to the modem.
The CA8361 interfaces the RS-232 connection to the modem.
Alternative, custom made, cables can be produced to customer’s requirements for volume orders.
Please contact Maxon for further details.
The use of the correct cables removes the need for multiple connections and the possibility of the
wireman making an error.
If possible, run RF cables separately from other cables and keep RF cables apart from one another to
avoid interference / coupling.
7.6 Fixing
We recommend that the MM-6854 data modem is securely fixed to a surface, either directly, or with a
suitable bracket.
The fixing hole dimensions are shown below:
163mm
2 off holes 6.7mm dia.

Note: We do not recommend that the data modem is fixed by cable ties to any wiring looms.
