SETUP/PHYSICAL INSTALLATION
Several steps must be performed prior to operating the SPM.
These steps include:
NOTE: For INFI 90 switches, OPEN and OFF have the same mean-
ing; CLOSED and ON have the same meaning.
1. Setting the address switch (S2).
2. Setting the port option switch (S3).
3. Setting the port operational option switch (S4).
4. Connecting the Request To Send (RTS) handshaking line
jumpers (JP3 and JP5).
5. Connecting the Data Terminal Ready (DTR) handshaking
line jumpers (JP4 and JP6).
6. Connecting the Clear To Send (CTS) handshaking line
jumpers (JP11 and JP12).
7. Connecting baud rate jumpers (JP9 and JP10).
8. Installing the SPM in the Module Mounting Unit (MMU),
and connecting termination cable if applicable.
9. Installing optional termination unit if applicable.
10. Connecting RS-232 cables.
NOTE: Jumpers JP1 and JP2 are factory installed ROM compatibil-
ity jumpers; DO NOT change or remove them. Removing or chang-
ing the jumpers will cause the module to operate incorrectly. A
jumper should be installed across pins 2 and 3 of JP1 and pins 2
and 4 of JP2.
After the SPM is installed, the serial port checkout (i.e., echo
test) and module bus checkout test can be run to verify SPM
operation. Refer to
for the procedures to run these
tests; a diagnostic terminal (dumb terminal) is required.
Address Switch (S2) Settings
The SPM can have one of 32 addresses (0 to 31) on the module
bus. This address uniquely identifies the SPM.
NOTE: The address must be a unique address within a PCU. Nor-
mally, addresses 0 and 1 are not used for an SPM since these are
reserved for communication modules.
The module address is set by positioning the five dipswitches
on S2; Figure
shows the location of S2. Table
is a
binary address conversion table for setting S2.
