3.1 SYSTEM DIAGNOSTICS COMMANDS – ID, IV, IS, SR, LI
The following five commands provide a means of interrogating the device to confirm the type of device present, the software
version of that device and the status.
The commands require no parameters and are used as follows:
ID Determine the device ID code - this is a code, which identifies the type of device, which is currently open for
communications. Issuing the ID command, which has no parameters, will return the code D:7210 This code is useful when
mixed devices may be present on the bus.
IV Determines the device software version - this identifies the release of software that is installed in the device. This is
useful when determining the availability of special commands or features that may have been requested for special
applications. Issuing the IV command, which has no parameters, will return the software identification code in the format
V:0201
IS Determine the device status - Issuing the ID command, which has no parameters, will return a result in the format
S:000000. This result comprises two 3-digit decimal values, which can be decoded according to the table below:
Leftmost 3-digit value: Rightmost 3-digit value:
1 Signal stable 1 not used
2 Zero action performed 2 not used
4 Tare active 4 not used
8 Not used 8 not used
16 Not used 16 not used
32 Output 1 on 32 not used
64 Output 2 on 64 not used
128 Output 3 on 128 not used
Therefore, the example result S:001000 decodes as signal stable (no-motion) no zero action, no tare and all outputs off.
The unsupported bits are reserved for use on other members of our instrument family and in the case of the EZE30 are
always set at zero.
