Lotek Wireless Inc SRX600 User Manual

CMDS parameters the modem needs, consult the modem’s user guide or Lotek 
Wireless Inc. for details.

CMDS stands for Command String and is used to initialize the modem. 

As soon as a modem is connected to the receiver and the receiver is Online, the 
CMDS parameters are sent to the modem. If no modem is connected the following 
message is provided, “No Modem, please select it via Setup/Comm”.

If the modem’s CMDS parameters are edited via the SRX Host while the modem 
is connected then the modem cannot function properly. There are two ways to 
correct for this: initialize the modem or unplug the modem and then plug it back 
into the receiver. In the case of the latter, as soon as the modem is again connected 
to the receiver, the receiver sends the new CMDS to the modem (like a refresh).

Initialize the modem via Setup > 1)Comm > 1)Configure > 1)Serial I > 5)Modem 
> 3)Initialize

. 

If a strictly RF modem is being used then Serial II can be used.

View the default factory settings via Setup > 1)Comm > 2)Factory Settings. 

The factory default settings are available for Baud Rate, Parity, Data Bits and Stop 
Bits. The default settings are shown in brackets in the display when this menu 
item is selected. 

Factory default settings can be set for either Serial I or Serial II (or both) via Setup 
> 1)Comm > 2)Factory Settings

 > 1)Serial I or 2)Serial II.
