The MSBipx card is equipped with jumpers (JU12, JU13, JU14). Before installing the
PS500 power supply, the jumpers on the MSBipx card are set to their correct positions.
See
Figure 9-1
and
Figure 9-11
.
Jumpers JU12 (KB1)/ JU13 (KB2)/ JU14 (KB3) connect the ground to the Clear-To-Send
(CTS) input of KB1, KB2 and KB3 data ports. When set to ON, the CTS option is
enabled.
The CTS is enabled by the customer whenever a printer or terminal is connected to
KB1/KB2/KB3 with a RS-232E cable.
RS-232 Cable
Applying the jumper between terminals 1 and 2 requires a five-lead cable (Rx, Tx, CTS,
RTS, and SGND).
Applying the jumper between terminals 2 and 3 requires a three-lead cable (Rx, Tx,
and SGND)
CTS On (1-2) - Use a 5-wire RS-232E cable (RxD, TxD, CTS, RTS, and SGND).
CTS Off (2-3) - A 3-wire RS-232E cable is acceptable (RxD, TxD, and SGND).
Configuring the "Handshaking" Option
Handshaking is the process whereby two communicating devices acknowledge and
recognize each other and open channels for communication.
The Coral IPx 500 system can be managed by three local workstations. Each local
workstation can be adjusted to a high or low level of handshaking protocol.
Figure 9-11
displays the jumper settings and describes the jumper configuration for each local
terminal: UART1, UART2, and UART3. An On setting indicates a high level of
handshaking protocol; an Off setting indicates a low level of handshaking.
The local workstations communicate with the Coral IPx 500 system via the auxiliary
connection and the MDF.

Configuring the CTS Jumper "Handshaking" Option
The KB1, KB2 and KB3 data ports may only be used to communicate with the system
processor for programming and maintenance purposes, or for retrieving station
message detail recording (SMDR) data or wake-up reports. It may not be used as
switched data ports.
