1. INTRODUCTION
1.1.
DESCRIPTION
The MicroTransEQ, MicroTransII, SPM-3000 and SPM-4000 utilize the Modbus – RTU slave protocol
using the EIA-485 signaling standards through a shielded twisted pair wire operating at a baud rate of
9.6Kbps to 115.2Kbps. Each device has a unique Modbus ID ranging from 1 to 254.
1.2.
SAFETY
1.2.1. Electrical Connections
Before any electrical connections are made, ensure the POWER SWITCH is in the OFF position.
1.2.2. Static Electricity
The circuit board contains components which are susceptible to damage caused by static electrical
discharge. Should it be necessary to remove the circuit board from the enclosure, appropriate
precautions must first be taken to ensure that the operator and the circuit board are at the same electrical
potential.

MODBUS COMMUNICATION BOARD & TERMINATOR SWITCH
For proper Modbus operation, the device that is electrically installed at the end of the network may
require the Terminator switch be moved to the ON position to prevent line and data reflection. If
Terminator is required, it must be applied to both physical ends of the network at the two end devices.
All other devices should have the terminator switch in the OFF position. The communication board is
located on the back side of the main board. See picture below for jumper location.

Perform the following steps to enter the Field Menus and make changes. Refer to Figure 1 below for
component locations.
3.1.1 Depress and hold the ZERO (S3) button for 3 seconds.
3.1.2 Depress the ZERO button repeatedly to scroll up through the Field Menus or repeatedly
depress the SPAN (S4) button will scroll down through the menus (see section 6.2).
3.1.3 To enter a specific Field Menu, depress the ACKNOWLEDGE (S2) button.
3.1.4 To make a change to a value or selection, depress the ACKNOWLEDGE button
repeatedly to select the digit you want to change and then depress the ZERO button to
increment the value or the SPAN button to decrement the value. Each button depression
will change the value by 1 count.
3.1.5 Once the change is made, depress and hold the ACKNOWLEDGE button for 3 seconds.
The new value or selection will be saved, the text will be displayed and the display
will return to the menu.

* MicroTransEQ responds to a read request from the master for these parameters by sending the value of
these parameters without any decimal points. So it is important that the Modbus software that reads
these parameters must also read the decimal point information or the programmer must set it manually in
the software to display the value correctly (See example on next page).

MODBUS EXCEPTION CODES
If the query sent by the Master host has errors in it, the MicroTransEQ , MicroTransII, SPM-3000 OR
SPM-4000 will respond with these error codes.
Error
Code
Contents
01H
Function code error
A function code other than 03H, 06H, or 10H has been set by the master.
02H
Invalid register number error
The register address you are attempting to access is not allowed in EQ.
03H
Invalid quantity error
The number of data packets (Blocks) being read or written is larger than 8.
21H
Data Setting Error
Attempted to write beyond register’s data limits
22H
Write-in Error
Register is Read Only
MicroTransEQ, MicroTransII, SPM-3000 or SPM-4000 Not Responding
In the following cases, the slave will ignore the query from the Master host.
When a communication error (overrun, framing, parity, or CRC-16) is detected in the command
message.
When the slave address in the command message and the slave address in the MicroTransEQ,
MicroTransII, SPM-3000 or SPM-4000 EQ do not agree.
When the command message data length is invalid.

SYMPTOM
SOLUTION
1.
Building Management System not
communicating with any of the
MicroTransEQ , MicroTransII, SPM-
3000 or SPM-4000 devices
1.
Verify each MicroTransEQ, MicroTransII, SPM-
3000 or SPM-4000 has a unique Modbus ID
number (See sections 4.1, 5.1, 6.3 or 7.2).
2. Verify the MicroTransEQ , MicroTransII, SPM-3000
or SPM-4000 baud rate matches the Building
Management System baud rate requirement (See
sections 4.2, 5.2, 6.4 or 7.3).
3.
Verify Modbus software configuration parameters
(See section 3.7).
4.
Verify data +&- connections on all MicroTransEQ,
MicroTransII, SPM-3000 or SPM-4000 devices are
wired correctly to the Building Management
System (See sections 3.1, 3.2, 3.3 or 3.4).
5. Check Exception code table (see section 8.4)
6.
Contact Factory Service Department.
2.
Building Management System
communicating with some
MicroTransEQ's, MicroTransII's, SPM-
3000’s or SPM-4000’s, but not others.
1.
Verify each MicroTransEQ, MicroTransII, SPM-
3000 or SPM-4000 has a unique Modbus ID
number (See sections 4.1, 5.1, 6.3 or 7.2).
2. Verify the MicroTransEQ , MicroTransII, SPM-3000
or SPM-4000 baud rate matches the Building
Management System baud rate requirement (See
sections 4.2, 5.2, 6.4 or 7.3).
3. Verify data +&- wires are connected correctly on
those devices not communicating (See sections 3.1,
3.2, 3.3 or 3.4).
4. Try setting the terminator switch (located on the
Modbus communication board) on the last device
in the communication chain to the ON position.
(See section 3.6)
5. Check Exception code table (see section 8.4)
6. Verify Modbus board is installed and seated
correctly. Modbus board is located on the back
side of the main board.
