4.4 Analog and Digital Communication The 25 Pin analog and digital I/O port on the rear panel of the instrument sends and receives analog and digital signals to other devices. These signals are commonly used to activate gas calibrators or for warning alarms.
Page 100: Analog Inputs
Ser in u s ® 30 U ser M an u al 3 .3 4.4.2 Analog Inputs The instrument is also equipped with three analog inputs with resolution of 15 bits plus polarity, accepting a voltage between 0 - 5 V. These go directly to the microprocessor and should be protected to ensure static/high voltage does damage the main controller PCA (instrument warranty does not cover damage from external inputs).
Page 101: Logging Data
Figure 86 – Analog & Digital I/O Individual Pin Descriptions CAUTION The analog and digital inputs and outputs are rated to CAT I. Exceeding 12 VDC or drawing greater than 400 mA on a single output or a total greater than 2 A across the eight outputs can permanently damage the instrument and void the warranty.

Page 121: Pressure Calibration
5.2 Pressure Calibration The pressure sensors are a vital component of the instrument operation. The pressure calibration should be checked on installation or whenever maintenance is performed. A thorough leak check must be performed prior to performing a pressure calibration (refer to Section 6.4.4).
Page 122: Figure 112 - Full Pressure Calibration Set-Up

5.5 Span Calibration A span calibration is a calibration performed at the upper end of the instrument’s measurement range. Ecotech recommends calibration at 80% of the full scale measurement or operating range of the instrument. While the instrument range is commonly set as a default 0 - 50 ppm, this is widely recognised as no longer being valid with modern digital communication and most regulators will now recommend a range more suited to local conditions.

Ser in u s ® 30 U ser M an u al 3 .3 Appendix B. EC9800 Protocol The Serinus implements a subset of the 9800 instrument protocol. Only the basic commands of reading the concentration value and setting the instrument calibration state (measure, span or zero) are supported.
Page 217 Bit 1 = SET→PPM selected, CLEAR→MG/M3 Bit 0 = reserved (LSB) DSPAN Function: Commands the instrument to enter span mode. Format: DSPAN, {<DEVICE I.D.>} {TERMINATOR} Device response: <ACK> if the instrument is able to perform the command, <NAK> if not. DZERO Function: Commands the instrument to enter the zero mode.

Ser in u s ® 30 U ser M an u al 3 .3 Appendix C. Bayern-Hessen Protocol The Serinus implements a limited subset of the Bayern-Hessen Network protocol. Only the ability to set the instrument calibration state (measure, span or zero) and read the gas concentrations are supported.
Page 219: Table 35 - Block Check Operation
Note: The I.D. of 97 is sent as the sequence 097. All I.D. strings must have three digits and must always be padded with ASCII zero characters. This is an example of a valid command to put the unit in the manual span mode if the instrument has an ID of 843: <STX>ST843 K<ETX>52 The block check operation is best shown with the following table:...

Table 37 – Failure Bit Map (Positive Logic) Failure Bit Meaning if set to 1 Flow sensor failure. Instrument failure. Note that while the In Maintenance mode reports as an instrument failure with a red light on the front panel, for Bayern- Hessen this particular error is merely a status instead of a failure.
