4.8Command Mode Guard Time (AT S154)
To enable the transmission of the command sequence within a packet of data, a guard time is placed around the command sequence. If the gap between the characters in the command mode string is less than this guard time, then the data string is assumed to be part of the data. This includes the gap between the last received data byte and the first “+”. The command is:
| AT S154=nnn<CR><LF> |
Where | nnn =0 to 255 ms |
Default: | 10 |
Read: | AT S154?<CR><LF> read the setting |
Read Return: | nnn<CR><LF> |
Example: | AT S154=10<CR><LF> set 10 msec time delay |
4.9Centre Radio Frequency (AT S155)
The channel change system for the Hermes is based around a centre frequency. The Hermes is programmed with a factory set centre frequency that is the centre of the RF switching band. The channel change is carried out by programming a channel step size (typically 12.5kHz) and setting
