alarm, transmit keyline activity and transmit status. When used with the modem option, an
annunciator panel indicates the status of the RS-232 interface lines (TXD, RXD, DCD, RTS,
CTS). If desired, the LED display can be turned off by moving a jumper inside the radio.
This may be desirable in applications where power consumption must be kept to an absolute
minimum.

MODEL NUMBER CODES

The model number as found on the serial number label may be used to determine the general
hardware configuration of the radio as it was shipped from the factory. Figure 1-1 illustrates
the significance of the various characters in the radio's serial number. The serial number
label is located on the end of the radio enclosure.

MAIN PRINTED CIRCUIT BOARD PCB VARIATIONS
The MDS 4310 Transceiver may be equipped with a 2314Axx main PC board or a 2013Axx
main PC board. The significant difference is the frequency range. Although the two PC
boards are similar, this manual covers transceivers with the 2314Axx main PC board which
has a frequency range of 350 to 512 MHz. Refer to manual part number MDS 05-2141A01
for specific information regarding transceivers equipped with the 2013Axx main PC board
which has a frequency range of 390 to 470 MHz. See Figure 1-2 for the location of the main
PCB part number label.
The main PC board part number can be identified without removing the housing cover. Refer
to Figure 1-1 to determine the transceiver frequency range. The frequency ranges identified
with a G, H I, J, K, L, M or N are equipped with the 2314Axx main PC board. The main PC
board part number can also be determined by using the
terminal. The command displays the main PC board part number and the revision level.
HREV
The nominal frequency operating range of the transceiver PCB can also be determined by
using the command via the HHT or terminal. The
MOD
board model number and the revision level.
See Chapter 3 –Programming and Diagnostics for detailed information on the use of the
Hand-Held Terminal.
