Part No. 001-3412-002
1.2.3 DL-3412 WITH RNET™ MODEM
The DL-3412 (Part No. 242-3412-xxx) can be
ordered with the 9600 baud Modem (Part No. 023-
3276-001), which supports the RNET™ communica-
tion protocol. This modem allows data communica-
tion between the Johnson Data Telemetry high specifi-
cation synthesized products and the Motorola RNET
radio/modems.
The Modem features include:
l User Programmable Data Rates:
9600/4800/2400/1200 baud in a 25 kHz bandwidth
OR
1200/2400/4800 baud in a 12.5 kHz bandwidth.
l RS-232 compatible using DE-15 15-pin connector.
l Simplex or Half-Duplex operation.
l RTS-CTS handshaking protocol with option for
configuring any two units as a digital repeater
(Half-Duplex or Simplex).
l Supports asynchronous, serial or transparent data
formats.
l Front panel LEDs provide indication for Transmit,
Receive and Power.
l Built-In Diagnostics reported both locally and
"Over-The-Air":
Reports specific unit programming
Loopback test feature
RSSI
Forward and Reflected Power
Temperature
Supply Voltage
l 8-Channels programmable with option to switch
channels remotely "Over-The-Air".
This board is programmed using an IBM PC or
compatible computer using MS-DOS and the RSS
programming software (Part No. 023-3276-005). Pro-
gramming instructions contained in the RSS Manual
included in the part number listed in Table 1-1.
1.2.4 DL3412 WITH DL3296 MODEM
The DL3296 modem (Part No. 023-3296-001)
provides digital data transmission at data rates up to
9600 baud. The DL3296 operates in Half-Duplex
mode. However, two transceivers can be combined to
provide Full-Duplex operation. The user interface is a
serial port through a 9-pin D-connector configurable
to either RS-232 or TTL signal levels. The data for-
mat is asynchronous with either 8 or 9 data bits. The
modem can operate in either standard DTE/DCE
handshake protocol or in Data Activation mode which
requires only receive and transmit data lines. The
baud rates are user selectable from 300 to 9600 baud
in a 25 kHz bandwidth or 300 to 4800 baud in a
12.5 kHz bandwidth.
1.2.5 DM-3412 SYNTHESIZER PROGRAMMING
The DM-3412, when used without the Universal
Loader Board (Part No. 023-3240-001) or DL-3276/
DL-3296 modem kits, requires customer supplied
circuitry to load the synthesizer with channel informa-
tion. The protocol that this circuitry must follow is
described in Section 3.
1.3 TRANSCEIVER IDENTIFICATION
The transceiver identification number is printed
on a label that is affixed to the PC board. The follow-
ing information is contained in that number:
