3.0 General Description
RA1202 is a Narrow Band UHF radio module for data only (no audio) communications. The
radio is primarily to be integrated into Symbol’s handheld XT15 and vehicle mount VH10 as
well as other potential future undetermined hosts.
There are 2 hardware variants of the radio module: 403-435 MHz and 435-470 MHz. The 2
hardware variants are configured during manufacturing into 12 radio types to meet different
countries’ approved frequency band, channel spacing, power level, baud rate and sub-band
restrictions. RA1202 supports the following Symbol’s modulations: 2 level 4800, 2 level 9600, 4
level 9600, 4 level 19200 baud FSK modulations at 12.5, 20, 25 KHz channel spacing with
factory configured output power of either 1W (+30dBm) or 0.45W (+26.5dBm)(non-FCC).
Communication between the radio and host is through a serial interface. Radio firmware resides
on a microcontroller inside the radio modules onboard flash memory. The antenna port of the
radio module is of u.Fl type and is meant for connection to an external antenna that is part of the
host device
RA1202 is designed to be integrated into a client host device only. It is not suitable for use as a
base station radio. RA1202 is backward compatible with the following legacy Symbol radios:
RA1001A; RA1001; TRX7370; TRX7345 (4 level modulations only);
