Black Box Short Range Modem
Switches S2-1 and S2-2: Word Length
Switches S2-1 and S2-2 are set in combination to determine the word length for asyn-
chronous data.
Switch S2-3: Extended Signaling Rate
The setting for switch S2-3 determines the range of variability the ME475A-R2 “looks
for” in asynchronous data rates (i.e., the actual variance from a given frequency level
the ME475A-R2 will tolerate).
Switches S2-4 and S2-5: RTS/CTS Delay
The combined settings for switches S2-4 and S2-5 determine the amount of delay
between the time the unit “sees” RTS and when it sends CTS. Options are no delay, 7
ms and 53 ms.
