Handling the 1410-B circuit board
Certain components used in the 1410-B are sensitive to static electricity and can be damaged by its
discharge. The 1410-B should be handled only in an ESD safe work area. The purpose of an ESD safe
work area is to prevent damage to sensitive components from spikes and static discharges. These areas
must be designed and maintained to prevent ESD damage.
1410-B circuit board assemblies must always be handled at properly designated work areas.
Stacking of 1410-B circuit boards and assemblies should be avoided to prevent physical damage.
Work areas should be kept clean and neat. 1410-B circuit board assemblies should be handled by the
edges. Avoid touching the circuits or components.
Physical installation
The 1410-B is a two board assembly. The main board contains the processor, radio and connectors. The
daughter board contains components for conditioning and monitoring power, and a 14-pin ribbon-cable
connector.
The 1410-B main board is 6.150” long x 3.250” wide. With the daughter board installed the 1410-B is
approximately 1” high. There are six mounting holes on the 1410-B main board designed for 4-40 screws
(see Figure 1). The 1410-B should be mounted on stand-offs or bosses so that there is a minimum of 0.5”
of clearance on all sides of the unit.
Tropos recommends that mounting the 1410-B with four screws through the holes at the corners of the
main board. Alternatively, the 1410-B can be mounted using the two SMA antenna connectors and the
two holes located under the daughter board.
Power
The 1410-B can be powered in two ways:
1.
The integrator can provide 10-28 VDC power to the 1410-B. This power is then regulated by the
1410-B. This is the preferred method of powering. Power can be applied to the either the
Ethernet or serial RJ-45 connector (see Figure 1). The pin assignments for these ports are shown
in Tables 1 and 2.
The 1410-B does not use 802.3af or 802.3at signaling.
2.
Regulated 5 VDC can be applied to the 14-pin connector on the daughter board. This will not be
regulated by the 1410-B. Therefore the following specifications apply:
5 VDC ± 0.5%
Ripple < 25 mV
Transient response < 50 mV
