1 GENERAL 1.1 System overview Trident is a device for on-site monitoring of fuel tanks. Trident gathers data from Labko 3000/3000 LPG or LabkoMax/LabkoFlex-series probes. Trident communicates with probes via Labko ILS protocol and displays realtime measurement data (tank level, volume, temperature and condensate water information). Different kind of alarm limits can be set for the measurements. All measurements and alarms are logged into a database, which allows extensive reporting. A system overview is presented in figure 1. 1.2 Features Figure 1.

7 POS INTERFACE PROTOCOL DESCRIPTION 7.1 COMMUNICATION IN GENERAL All communication is controlled by the host unit (e.g. PC). The host unit sends commands including the probe number. All ASCII command strings consist of a two character command, two character probe number n 1n 2, a possible parameter and a stop character (<CR> = carriage return, ASCII 0D HEX). The ASCII response strings consist of a start character (#, ASCII 23 HEX), a result string and a stop character (<CR>). 7.2 INQUIRY COMMANDS LEVEL/VOLUME INQUIRY $Vn 1 n 2 <CR> By this command probe n 1n 2 sends the result in the mode that is preset by the $D command. Response: #xl 1...l 6 <CR> where x = always zero l 1...l 6 = result in units according to preset parameters (result mode), 1...6 digits LEVEL INQUIRY $Mn 1 n 2 <CR> By this command probe n 1n 2 sends the level in millimetres (irrespective of the result mode) in the same mode as the $V command when the result mode is 0. #l 1...l 6 <CR> l 1...l 6 = result in units according to preset parameters (result mode), 1...6 digits TEMPERATURE INQUIRY $Tn 1 n 2 <CR> By this command probe n 1n 2 sends the temperature of the measured liquid. Response: #+/-t 1...t 3 <CR> where +/- = + or - sign t 1...t 3 = temperature reading, 1...3 digits, scaled as follows: 6 = 0.6 C 84 = 8.4 C 237 = 23.7 C Copyright 2017 Labkotec Oy 30/34

CONDENSED WATER LEVEL INQUIRY $Gn 1 n 2 <CR> By this command probe n 1n 2 sends the water level on the bottom of the tank. (The measurement is possible only for non-conductive liquids, such as fuels.) Response: #m 1...m 4 <CR> where m 1...m 4 = water level in millimetres, 1...4 digits WATER VOLUME WVn1n2<CR> This command is here to keep compatibility to old systems. Use Water Level command instead of. ALL VALUES INQUIRY $An 1 n 2 <CR> By this command probe n 1n 2 sends the level in tenths of millimetres, volume, temperature, water level and possible alarms. Response: #m 1...m 5 ;v1...v6;t1...t4;g1...g4<cr> where ; = field separator (semicolon) m 1...m 5 = level as an integer in tenths of mm (1...5 digits) v 1...v 6 = level/volume according to result mode (1...6 digits) t 1...t 4 g 1...g 4 = temperature as an integer in tenths of C(t1 can also be a minus sign, 1...4 characters) = water level in millimetres (1...4 digits) The contents of the v 1...v 6 reading is determined by the result mode (set by the $D command) and indicates either the level in millimetres or the volume in litres. Copyright 2017 Labkotec Oy 31/34

7.3 SOME HINTS 7.4 EXAMPLES The typical response time is two seconds. It is recommended to read response char by char until to get end char (CR). After that is response ready. Timeout value should be something like 5 seconds. If Trident does not send a response, try sending a <CR> and send the original command again. After a <CR> Trident is ready for receiving a new command. After initializing the serial port of the host send one or two <CR> commands to Trident to clear the input buffer from wrong characters caused by power-up. There is some command and response examples. $A01 #03934;008438;0245;0020 $A01 #03934;008438;-245;0020 $G01 #0020 $V01 #0008438 $M01 #00393 $T01 #+245 $T01 #-245 WV01 #0 Copyright 2017 Labkotec Oy 32/34
