Page 3: Chapter 1 - Introduction
CHAPTER 1 - INTRODUCTION ongratulations on purchasing the Garnet Instruments S L Access ™ Data Portal. The S L Access ™ compliments the S Annihilator ™ 806-B, 806-Bi, or S L Special ™ 808-P2 and SeeLeveL ProSeries II 810-PS2 gauges by providing an additional volume readout in the cab of your truck. -
Page 4: Chapter 2 - Features
CHAPTER 2 - FEATURES he S L Access ™ has been uniquely designed for specific applications and with specific features: Standard S L Access Features 1. The signal between the 806-B, 806-Bi, 808-P2 or 810-PS2 display and the S L Access ™ is digitally encoded so the signal line can be connected using a standard 7 pin trailer plug. -

Page 7: Chapter 4 - Display Programming
CHAPTER 4 - DISPLAY PROGRAMMING he S L Access ™ display shows the tank level by repeating the information shown on the 806-B, 806-Bi, 808-P2 or 810-PS2 gauge. The 4-20 mA analog output is calculated from the display level with a 4 mA output corresponding to a display level of zero, and a 20 mA output corresponding to the full scale level programmed into the S L Access ™... - Page 8 8. If the full scale calibration is below 103, the display will be unable to calculate a valid calibration, and will show cErr (calibration error) after a few seconds. The existing calibration will be retained, and the display will return to normal operation. To view the existing calibration: 1.

• All messages (SeeLeveL Slave -> ELD MASTER) obey the following format: [Destination: Master address = 0x00] [Originator: Garnet address = 0x19] [total number of bytes in message] [message [payload – optional depending on message] [Checksum (16 bit: 2 bytes)] •... - Page 10 SeeLeveL Query Response (SeeLeveL Slave -> ELD Master) • Value: 0x01 • SeeLeveL responds with model ID (1 byte), H/W Rev (1 byte), S/W Rev (2 bytes), alarm capability (1 byte), and SN support (1 byte). If the SeeLeveL device supports a unique serial number, it will follow (8 bytes in length).

- Page 12 SeeLeveL Error Response (SeeLeveL Slave -> ELD Master) • Value: 0x0F, 1 byte payload • SeeLeveL issues this response if a command/message is not supported. Payload = unsupported message code. • Example: ELD has previously issued a SeeLeveL Query Alarm Liquid Level Message (0x07) to a SeeLeveL device which does not support alarms: •...
- Page 13 • ELD sends handshake response • SeeLeveL sends reply to original ELD request if handshake response is correct and on time. • The “handshake accepted acknowledge” message is not used here. • Upon power-up of the display, the “20 requests” is reset so a handshake is needed for the first liquid level request.
