TechnoKom © 2016
AutoGRAPH controller is equipped with an RS-232 (EIA/TIA-232-E) bus.
RS-232 is a 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.
Current version of AutoGRAPH controller supports connection of following devices via RS-
232 bus:
1. NMEA 0183 coordinates output
– intended to send coordinate data in NMEA 0183
protocol to any external device connected to the tracker via RS-232, e.g. AutoGRAPH-
NAVIGATOR display. This mode is set by default.
2. CAN-LOG (or CAN-LOG 2)
– intended to receive data from CAN-LOG 2 device.
The CAN-LOG 2 is 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. 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
– intended to receive
coordinates from a high-precision receiver in NMEA 0183 protocol.
4. APC (automotive passenger counting) output to RS-232 interface
– intended to
transfer data from APC systems IRMA MATRIX and IRMA BASIC to external device via RS-
232.
5. VDO RS232
– intended to receive .ddd-files from tachograph Continental VDO DTCO
3283 and then transfer this data to server.
Before connecting any device to the tracker, the required mode of RS-232 interface must
be selected in the controller. The customer can set this using the GSMConf configuration
program or control commands via SMS or the server.
