1892 1139 - RSX Range of Intelligent Modems User Guide - v7.1 / Nov 2007 5
1.1.2 OEM PCB
If supplied as an OEM PCB, the unit has dimensions and mounting as shown in Figure 5.
It can also be supplied with a PCB connector rather than the 9-way D-type connector
shown.
The unit requires a small amount of heatsinking for the on-board regulator to dissipate of
the order of 2W. This is provided in the cased version by the regulator being screwed
down to a supporting pillar in the diecast case. The heatsink tab is connected to system
0V, and so requires no insulators where the heatsink may be grounded.
