5.2.9 Field Programming Software
The TSLM is configured by means of the Field Programming Software (FPS)
(Part No. 039-2200-210). Channel frequencies for 8 channels are also selected using the
FPS.
The following parameters may be adjusted with the FPS:
•
Channel 1 - 8 TX and RX frequencies
•
Baud rate, word length, parity
•
Timing parameters
•
Diagnostics on/off
•
Carrier detect threshold level
•
Power output
In addition, the FPS provides the tools for test transmissions and allows test statistics to
be obtained and displayed. See the Programming Software on-line help file for details.
5.2.9.1 Channel Selection
Channel frequencies are programmed for 8 channels using the TSLM FPS. The
current operating channel is selected in one of two ways:
1.
Utilizing hardware jumpers by strapping connection on the Data Port
Connector. There is a 10k ohm pull-up resistor on each line (CS0 to CS2)
(refer to Table 5.3).
2.
By making changes with the TSLM FPS. Select the channel from the TSLM
Offline Diagnostics or User Test interface.

5.2.10 RTS/CTS or DOX Operation
The unit operates transparently at the data speed selected by the Field Programming
Software.
In DOX mode, the TSLM will begin transmitting when data is ready to send (no RTS
signal required) and terminate when no data remains to be sent.
If RTS/CTS operation is selected, the DTE starts a data transfer by asserting RTS.
A CTS response is returned after the transmitter has been keyed and the remote modem
has had sufficient time to synchronize.
