Configuration
ETIC - MR1200 - USER MANUAL - 908709-02 Page 27
This parameter determines the length of time after which the MR1200 goes to sleep once transmission
and reception of data has ceased :
att_ina format
de 0001 to 6000 MMSS
0000 * unlimited wait
MM : minutes (2 ASCII numbers) SS : seconds (2 ASCII numbers)
The value 0000 prevents the modem from going to sleep.
3.4.5. Other parameters
Parameter 050 [tp_emi]
Fixes a limit to the length of the MR1200's transmission time, serving to avoid both a modem
monopolising the radio channel and the risk of transceiver RF stages overheating :
tp_emi units
from 1 to 255 x 1 s
0 * no limit
A value of 0 removes all limits on the duration of transmission.
Parameter 051 [tp_sil]
A minimum period of post transmission silence can be defined, to allow other MR1200 modems the
time to access to the radio channel :
tp_sil
units
de 1 to 255 x 1 s
0 * = 6/20 x duration of
transmission
The MR1200 ignores this parameter if no transmission time limit has been set (parameter
tp_emi =
null).
Parameter 052 [tp_ae]
Corresponds to the length of time the MR1200 will wait before ending radio transmission, once there is
no more data to be sent :
tp_ae units
de 0 to 255 x 20 ms * 1 (=20 ms)
Enter a low value (20 ms) where applications function by a rapid exchange of data with brief
request/response intervals.
Enter a higher value (100 ms or more) where : - data messages are long ; the control terminal's
transmission speed is less than 2400 bits/s ; data flow is irregular.
