6. Connections
6.1 Connecting TTM-10L in RS-485
High-level computers (parent stations) TTM-10L (child stations)
Install an end of line resistor at both of the farthest devices in the parent station and the mobile unit.
For a resistance value, use one that matches the characteristic impedance of the cable. Provided that
the synthesis is set to at least 75
Ω
.
6.2 Connecting TTM-10L in RS-232C
High-level computers (parent stations)
TTM-10L (child stations)
For actual use, the following connection is required inside the connector in the parent stations: CS
(transmission permission) and ER (data terminal ready), and RS (transmission request) and DR (data
set ready) and CD (reception carrier detection).
