The new RS232C board contains two ports, each of which is capable of providing an RS232C or 20-mA current
loop signal. Each system can have up to three 562-513 RS232C boards. Looking at the board from the front of
the card rack, the top connector is referred to as the LOCAL port. The bottom connector is referred to as the
REMOTE port. When a system has three RS232C boards, the ports will be labeled as shown in Table F.

Switch package SW1 (Figure 11) is used to select the baud rate for each port. There are three baud rates
available to the system. See the CPU board jumper package Jl (Figure 1) to determine the baud rates for the
LOCAL and REMOTE ports.
Set the switches on SW1 as follows:
PORTS 1,3,
