4-14 Chapter 4: Appendix D - RS-485/422 Option
Intellicon-NT960/PCI User's Manual, ver. 0.02
Installation
The ACM/Flex16 module has four 72 pin SLIM sockets which
accept Serial Line Interface Modules. Each SLIM provides the
RS-232 or RS-485/422 or 20mA Current Loop receivers and
transmitters to condition four serial ports. SLIM 1 socket (SM1)
interfaces ports 1, 2, 3, 4; SLIM 2 socket (SM2) interfaces ports
5, 6, 7, 8; SLIM 3 socket (SM3) interfaces ports 9, 10, 11, 12; and
SLIM 4 socket (SM4) interfaces ports 13, 14, 15, 16. Please refer
to Figure 9 for the location of the SLIM sockets and to
Appendix F: SLIM Insertion/Removal for the proper
procedures to installing and removing SLIMs.
Your ACM/Flex16 and Serial Line Interface Module (SLIM) are
very sensitive to static electricity. Make sure that before you
remove them from the anti-static shipping bag, you wear an anti-
static wristband. When you remove them from the anti-static bag,
handle them only by the edges and place them on the anti-static
bag or an anti-static mat.
LED interface indicators
You can install RS-232 and/or RS-485/422 and/or 20mA Current
Loop Serial Line Interface Modules in your ACM/Flex 16. The
ACM/Flex16 has LED indicators on its front panel to show you
the electrical interface in use for a specific group of four ports.
When the LED is red the RS-485/422 interface is in use; when it
is green the RS-232 interface is in use; and when it is amber the
20mA Current Loop interface is in use. Please refer to Figure 10
for the location of these LED interface indicators.
