ER03: RS485 Communication Error
This type of error is a communication error
between the serial device and Controller unit
and the cards in the Multi-Taskerâ„¢ Enclosure.
7.3.4. [SETUi]
This command sets the unit ID number for the
MT100-101 Multi-Taskerâ„¢ Enclosure.
Ui = Unit ID
i = number from 0 to 9
To assign an ID for a unit, first turn ON that
particular unit leaving other units OFF and
send this command.
Example:
a) [SETU0]
After this command is executed, all commands
for this unit may either include U0 or not
include U0. Factory default is unit ID 0.
Example:
[Cn] = [CnU0]
[VERCn] = [VERCnU0]
[ON123Cn] = [ON123CnU0]
[SETU6]
After this command is executed, all commands
for this unit must include U6 (i.e. [CnU6],
[VERCnU6], etc). This command can be used
for single or multiple unit operation.
If there are 3 enclosures being used, set unit
ID's using the following procedure:
1) Turn OFF all units.
Turn ON the unit that you want to assign
unit ID no. 1
Send the [SETU1] command.
2) Turn OFF all units.
Turn ON the unit that you want to assign
unit ID no. 2
Send the [SETU2] command.
3) Turn OFF all units.
Turn ON the unit that you want to assign
unit ID no. 3
Send the [SETU3] command.
7.3.5. [HELPUi]
This command displays all RS-232 commands
available for controlling of the MT101-104.
7.4 ASSIGNING THE SAME UNIT ID TO
MULTIPLE UNITS
When there is more than one unit being used,
unit ID 0 to 9 can be used for each unit. If
identical units are used, the user may assign
the same unit ID in order to operate these
units simultaneously with the same command.
Example:
To assign unit ID 1 for 3 different units:
a) Turn on only these 3 units.
b) Send the [SETU1] command. After sending
this command, all of the 3 units will have unit
ID=1;
Command [ON1C2U1] will turn on
input/output#1 on card 2 of these 3 units at
simultaneously. Caution must be used when
multiple units are assigned the same unit ID.
1) Do not use the following commands for
multiple units with the same unit ID: [Ci], [VER]
and [RD] These commands will request
feedback such as card status, version, or
content of a register.
2) Do not use suffix "F" in a command for
multiple units with the same unit ID. (note:
using F will request feedback)
Note: Using commands [Ci], [VER] and [RD] or
suffix "F" for multiple units with the same unit
ID may return an unwanted response because
more than card will send feedback
simultaneously.
