Motorola ML910 - Manual (Page 68)

2-24 Operating Your Computer
Using the PRM240 Wireless Modem (Optional)
Your ML910 RUGGED NOTEBOOK may be equipped with an embedded 800 MHz
PRM 240 radio modem to provide data connectivity via a Motorola Private DataTAC
communications network. This 2 Watt modem is generally compatible only with
Private DataTAC systems designed to operate with portable and low power mobile
devices,
not those systems requiring higher power, external modems such as
Motorola's VRM 850. Being embedded, the PRM 240 is protected from outside
elements such as moisture, dust, sand, humidity and the long-term effects of extreme
temperatures.
This ML910 RUGGED NOTEBOOK modem solution also includes an embedded
antenna, typically for when the ML910 is used outside of a vehicle. An external antenna
pass-through option is also available to be used in conjunction with a mobile docking
station and an external antenna, to enhance radio signal coverage and range when the
ML910 is used inside a vehicle.
The modem uses a serial interface to communicate with the ML910’s internal controller.
The protocol supported over this link is the Motorola Native Control Language (NCL).
Motorola and third-party applications or middleware designed specifically to use this
protocol are required, but not included with the ML910.
NOTE:
Please refer to your PRM240 user manual for more information on the installation and
configuration of the modem.
The PRM240 modem features:
− High sensitivity reception
− Low standby current consumption
− Auto-wake up of host on incoming messages
− Roaming capabilities as used in the Private DataTAC network
− Easy to install, service and update
