CARD CONTROL

Card control commands allow the main functions of 
the card to be executed over the RS-232 bus, or 
from the front panel’s programmable keys.

13.  

[…S] – SAVE

This command saves the configuration 
command being sent in memory.  Send the 
command  [ON4C4S] to enable Output 4 and 
save the setting. After reset or power-up, the 
Output 4 of C4 will be enabled.

14.  

[ON]

This command will enable an output of a single 
card, or a group of cards.

SINGLE CARD OPERATION

Command Format:  [ONmCn]

m

= Output no. (m = # from 1 to 4)

Cn = Card ID (n = # from 1 to max slots)

Example:

There is an 

MT108-103

card in slot 4.  All of the 

outputs are off.

1)

[ON1C4]: Turns on only Output 1 of C4.

2)

[ONC4]: Turns on all outputs of C4.

GROUP OPERATION

This command enables output "m" for each card 
in group "k".

Command Format:  [ONmGk]

m

= Output no. (m = # from 1-4)

Gk = Group no. (k = # from 1-8)

Example:

[ON1G1]: Turns on Output 1 for each card in 
G1. See the GROUP commands for a detailed 
explanation of groups.

PATH OPERATION

This command will set the path for the output, 
but it is not active until the switch command, 
[SW], is executed. Commands ending in "P" are 
not executed immediately. The path for outputs 
on multiple cards or the same card may be 
preloaded.

Command Format:  [ONmCnP]

m

= Output no. (m = # from 1 to 4)

Cn = Card ID (n = slot # from 1 to max slots)

P

= Path

Example:

There are two 

MT108-103

cards, C6 and C7. 

Enable Output 1 of C6 and Output 3 of C7 
simultaneously. To do this, send the following 
commands:

[ON1C6P]

[ON3C7P]

[SW]

15.  

[OFF]

This command disables one or all outputs of a 
single card or a group of cards.

SINGLE CARD OPERATION

Command Format:  [OFFmCn]

m

= Output no. (m = # from 1 to 4)

Cn = Card ID (n = # from 1 to max slots)

Example:

C4 has Outputs 1, 2, and 3 turned on.  The 
following commands may be used to turn off the 
outputs.

1)

[OFF1C4]: Turn off Output 1 only.

2)

[OFFC4]: Turn off all outputs.
