ML
8 bits
Data0
8 bits
-----
DataN
8 bits
Chksum
8 bits
with the following definitions made:
Sync (8 bits) - marks the start of a frame when not preceded by an ESC character. When using a Sync/Esc
(Framing) Mode, the Field Programming Software will stuff this character automatically.
ML (8 bits) - the length of the frame. ML is the number of characters left to be received including the checksum
but excluding any ESC characters added as part of the protocol. When using a Sync/Esc (Framing) Mode, the Field
Programming Software will stuff this character automatically based on the number of Data Characters.
Data 0 - N(8 bits each) - frame information
Chksum (8 bits) - the 8 bit 2s complement of the sum of the frame less the SYNC character and any additional
ESC added characters ignoring the carryout of the high order bits. When using a Sync/Esc (Framing) Mode, the
Field Programming Software will stuff this character automatically.

SECTION 4
ALIGNMENT AND TROUBLESHOOTING
4.1 GENERAL
4.1.1 PERIODIC CHECKS
This module should be put on a regular maintenance schedule and an accurate performance record maintained.
Important checks are receiver sensitivity, transmitter frequency, modulation, and power output. It is recommended
that module performance be checked annually even though periodic checks are not required by the FCC. Section 4
outlines these tests.
4.1.2 SERVICING
The majority of the components used on the printed circuit boards are surface mount devices. JSLM2 module
component level field repair is not recommended. Specialized training and equipment are required to service board
level components. Equipment should be returned to the factory for repair.
4.2 PERFORMANCE CHECKS
4.2.1 CHANNEL FREQUENCY
The module frequency is controlled by a temperature compensated crystal oscillator (DCXO) which has a
frequency stability of ± 1.5 parts per million over a temperature range of -30 to + 60° C. When transmitting (for
example) at 450 MHz, the output frequency should be 450 MHz ± 675 Hz over temperature. The operating
frequency may be adjusted through the case of the JSLM2. Connect the User Interface Cable included in the
JSLM2 Field Programming Kit (part number: 250-2100-001). Connect the antenna port to a frequency counter or
other frequency measurement instrument. Locate the Frequency Adjust Access Hole on the bottom side of the
Loader Board (see Figure 4-2). Enable the transmitter PTT Line and use a small screwdriver to adjust the DCXO
for the desired transmit frequency.
Caution: An RF attentuator may be required depending on the power handling capability of the measuring
instrument.
4.2.2 RF OUTPUT POWER
The RF output power may be verified with an accurate power meter connected with a short 50 ohm cable to the
Antenna Connector. See Section 1, General Specifications for module specifications. Transmitter alignment is
performed in the factory and is not a recommended field adjustment.

b. Increment by 10 using the Page Up/Page Down keys
After changing the Transmit Deviation Level, a Write must be performed to the JSLM2 transmitter. To return to the
factory default level, check the Default box and perform a Write to the JSLM2 transmitter.
4.2.4 TRANSMIT DEVIATION LIMITING
Transmit Deviation Limiting is preset at the factory to 2.20 +.10 kHz and is not field programmable. Deviation
Limiting may be checked by injecting a 1000 Hz tone at 1.0 Vrms to the Aux Input or Mic Input.
4.2.5 RECEIVE AUX OUT AND AUDIO OUT LEVELS
Receive Aux Out and Audio Out levels are preset by the factory. Refer to General Information, Section 1, for
specifications and levels. These levels are adjustable utilizing the JSLM2 Field Programming Software. Select
Parameters Settings/Rx Aux Level or Rx Audio Level. Values are changed by:
1. Un-check the Default box
2. Highlight the value
3. Change the value
c. Increment by 1 using the Arrow Up/Arrow Down keys
d. Increment by 10 using the Page Up/Page Down keys

RF Exposure Compliance Requirements
JSLM2 VHF Analog Telemetry Module
FCC Rule: 1.1307, 1.1310, 2.1091 (b) (d), 2.1093
IC Rule: RSS-119 Section 9, RSS-102 Section 2.2
Description of Compliance:
The JSLM2 will be professionally installed in the SCADA (Supervisory Control And Data Acquisition) market and
will be mounted with a fixed RTU (Remote Terminal Unit). A typical installation would use a maximum gain
antenna of 10 dBi mounted on a tower. A minimum separation distance of more than 141 cm must be maintained
between the radiating structure and any person to classify as a mobile under FCC MPE regulations. Note: It is the
responsibility of the user to guarantee compliance with the FCC MPE regulations when operating this device
in a way other than described above.
The calculation for the more stringent specification, a General Population/Uncontrolled Mobile device according to
section 2.1091(b) and section 1.1310 Note 2 is shown below:
