The AutoGRAPH-GSM controller is equipped with an RS-232 (EIA/TIA-232-E) bus.
RS-232 is bi-directional serial data transmission interface between a transceiver and
peripheral devices. The main advantages of the RS-232 interface are reliability, and flexibility
of implementation.

The AutoGRAPH-GSM controller supports
interaction with following devices via RS-232
Bus:
1. AutoGRAPH-NAVIGATOR
– is a
software-based vehicle tracking system
running on a laptop and designed by
TechnoKom Ltd. When connected to the
controller, the AutoGRAPH-NAVIGATOR
is capable of displaying current position
of the vehicle on a map, monitor of
movement parameters and routing.
Using the AutoGRAPH-Navigator, a
dispatcher can send a list of tasks to a
driver and monitor progress of the tasks.
In addition, the device is capable of
message handling between the driver
and the dispatcher. The AutoGRAPH-
NAVIGATOR is supplied with a special
connector for connecting to the controller.
2. CAN-LOG 2 (CAN-LOG) –
is a device
intended for connecting to the vehicle
CAN Bus, scanning data and transferring
it to another device connected to the
CAN-LOG via RS-232. The CAN-LOG
2 supports many CAN protocols. When
connected to the controller, the CAN-LOG
is capable of reading data from the CAN
bus and transferring it to the controller,
even if the CAN protocol is not known in
advance. The data from the CAN-LOG 2
is transferred in text format.
3. External GPS / GLONASS receiver
with NMEA 0183 standard -
is a high-
precision receiver, which allows to acquire
asset position with high accuracy.
