TSIU - Serial Interface Board
System:
DK40i Base KSU (plugs into KSU main PCB)
Circuits per PCB:
two TTY/RS-232 interface ports
Interfaces with:
SMDR connection for call accounting device
customer-provided external modem for local/remote maintenance from a PC with
DKi Admin
Older Version(s):
none
The TSIU PCB enables the DK40i system to connect to various hardware devices. It does not have
an internal modem and does not support IMDU. (See
Figure 3-23 .)
Only one TSIU can be installed per DK40i system. When installed, the TSIU port functions are
identified and enabled automatically when power is turned on and the PIOU can still be installed
for zone paging. Port 01 is TTY (Program 76-1, code 1) and Port 02 is disabled (Program 76-1,
code 0). If the same function is programmed for an TSIU port and a PIOU or PIOUS port, only the
TSIU port functions.
The communication parameters for all TSIU TTY ports are:
♦
Data word bits = 7
♦
Parity = even
♦
Stop bits = 1
The communication parameters for a TSIU SMDR port is:
♦
Data word bits = 8
♦ Parity = none
♦
Stop bits = 1
TSIU Installation

See Figure 3-23 for installation.
TSIU Programming
Program 03: No assignment is necessary. TSIU is automatically enabled when installed and power
is turned On. It is not assigned to a slot.
Program 76-1X-Y: Assigns each installed TSIU port to a function. Where X identifies the TSIU
port number (1~4) and Y identifies the TSIU port function:
♦ Y=1, RS-232 TTY (Program 77-1, LED 14 Off)
♦
Y=2, SMDR
♦ Y=4, SMDI
♦
Y=0, No function - this should be used for any TSIU ports that are not used.
Note Function codes set in Program 76-1X-Y override PIOU and/or PIOUS function codes 41
set in Program 03.
