Termination Resistors – Fig. 2.2

Under normal operating conditions the slave termination resistors are linked out. For long transmission lines, termination resistors
are required on the last slave in the chain and the host computer/computer terminal – see Fig. 2.2A. The slaves termination
resistors are linked-in using plug-in link (LK1) on the serial module – see Fig. 2.2B.

2.5

RS485/422 Standard

The RS485 standard quotes connection of thirty-two slaves maximum, to any single driver (computer terminal or host computer);
the RS422 standard quotes connection of up to ten slaves. However, these numbers can be increased if the driver’s serial port permits.
