CONNECTIONS
The connection terminals are along the edges of the Analog Transmitter. These are
divided into input sensor terminals (1 to 16), the Address terminals (A, S), and the
data highway terminals (+, S, -), as shown below.
5 .1 Address
Leaving these two pins (A, S) open, sets the address of the MTL831C/MTL831C-
PS to “1”. A jumper on these two pins sets the address to “2”. Either is valid for a
system with only one MTL831C/MTL831C-PS connected to the MTL838C. When
two MTL831C/MTL831C-PSs are connected to a single MTL838C, they must be
addressed uniquely. If they are on the same address, only one will communicate
with the MTL838C. The address affects where the data is seen in the PC Software
and what is available on the RS485 ports:
