Module Installation and Operation
2-4 MP2100M-LS-2 Modules - Installation and Operation Manual
Sections 1, 2, 3 These sections select the channel transmission mode
(synchronous or asynchronous). With respect to the
transmission mode (synchronous or asynchronous),
the channels are divided into three groups.
• Section 1: controls channel 1.
• Section 2: for /X.50 and /SDM versions, controls
channels 2 through 5, and for /X.58 versions -
controls channels 2 and 3.
• Section 3: for /X.50 and /SDM versions, controls
channels 6 through 10, and for /X.58 versions -
controls channels 4, 5, and 6.
For each group, select the desired transmission mode
by setting the corresponding section to OFF for
asynchronous operation, or to ON for synchronous
operation.
Sections 4, 5 These sections select the word length (8 through 11
bits) used by channels 1 through 5 (for /X.58 versions
- by channels 1, 2, 3) when configured for operation
in the asynchronous mode. The required word length
is obtained by adding the number of start bits, data
bits, parity bits, and stop bits generated by the user's
asynchronous equipment. The settings required for
each word length are identified in figure 2-2.
Sections 6, 7 These sections select the word length (8 through 11
bits) used by channels 6 through 10 (for /X.58
versions - by channels 4, 5, 6) when operating in the
asynchronous mode.
Section 8 Reserved for future use. Set to OFF.
Modules LS-2A
and LS-2A/2TS
Modules LS-2A and LS-2A/2TS have one switch, designated S1, which is used
to select the transmission mode of the channels. The switch is located on a
daughter board, and is accessible from the top of the board.
Figure 2-3 identifies the location of the switch, and the functions of its sections.
The switch is identical to the switch S1 located on the MTLS-2 and
MTLS-2/2TS modules, explained in the previous section.
