To move the PCB to the next highest slot
1. Identify (mark) the attendant console and all station PCB wiring connectors so they can be 
removed and then reinstalled on the same PCB later (console station PCBs include: PDKU, 
RDSU, PEKU, PESU, RSTU, PSTU and RATU PCBs).
2. Turn system power OFF.
3. Disconnect the connectors from the attendant console and all station PCBs listed in Step 1.
4. Remove all station PCBs listed in Step 1.
5. Install each PCB that was removed in Step 4 into the next highest empty station PCB slot 
number. Skip over all other types of PCBs that were not removed. Example: If a PDKU was 
originally in slot 11 and a PSTU was in slot 12, the PDKU is moved to slot 12 and the PSTU is 
moved to slot 13. The programming telephone will then be on the 6th circuit (port 005; or, 013 
until Program 03 Code 49 is set for slot 11) of the PDKU in slot 12.
6. Connect all PCB connectors that were removed back into the same PCBs they were removed 
from in Step 3.
7. Turn the system power ON and note that the programming telephone is on port 13 and all other 
ports are shifted up by eight ports. Program slot 11 with Code 49 and all other slots with the 
appropriate codes using Program 91-1 and/or 03.
Next, cycle system power OFF (five seconds) and ON, or, run Program 91-2 to transfer 
Program 03 data from temporary to working memory. At this time the programming telephone 
changes from port 13 to port 005 and all other ports shift down by eight ports.

To install an RSIU PCB into an existing system with DID and/or Tie lines
NoteThe steps in “RSIU Installation” on Page 7-46 apply to installing an RSIU into an existing 
system. Hence, most PCBs must be moved to the next highest slot using the following 
steps.
1. Identify (mark) all PCB wiring connectors so they can be removed and then reinstalled onto 
the same station PCB later.
2. Turn system power OFF.
3. Disconnect the connectors from all PCBs except PIOU2, PIOUS2, RSSU, PEPU, RCIU, and 
RCIS.
4. Remove all PCBs except PIOU2, PIOUS2, RSSU, PEPU, RCIU, and RCIS.
5. Each PCB that was removed must be installed into the next highest empty PCB slot number. 
Skip over all other types of PCBs that were not removed.
NoteThis step may have to be modified for the RDTU PCB, depending on the configuration to 
meet the requirements of RDTU slot assignments per tables in Chapter 6 – DK424 T1.
6. Connect all PCB connectors that were removed back into the same PCBs from which they 
were removed.
7. Turn the system power on and note that the programming telephone is on port 13 and all other 
ports are shifted up by eight ports. Program slot 11 with Code 49 and all other slots with the 
appropriate codes using Program 91-1 and/or 03.
Next, cycle system power OFF (5 seconds) and on or, run Program 91-2 to transfer Program 
03 data from temporary to working memory. At this time the programming telephone changes 
from port 13 to port 005 and all other ports shift down by eight ports.
RSIU, RSIS, RMDS Programming
Program 03: Programs slot 11 with code 49 to identify that the RSIU PCB is installed in slot 11.
Program 76-1X-Y: Assigns each installed RSIU port to a function. Where X identifies the RSIU 
port no. 1~4 (see Figure 7-23 for RSIU port number configuration) and Y identifies the RSIU port 
function:
©Y=1, RS-232 TTY (Program 77-1, LED 14 OFF)
©Y=1, RMDS modem (Program 77-1, LED14 ON)
©Y=2, SMDR
©Y=3, MIS or SMIS
©Y=4, SMDI
©Y=5, Open Architecture
©Y=0, No function - this should be used for any of the four RSIU, RSIS, RMDS ports that are 
not used.
Notes
lFunction codes set in Program 76-1X-Y will override RSSU, PIOU2, and/or PIOUS2 function 
codes (41, 42, 43) set in Program 03.

lThe TTY and modem function cannot operate on separate RSIU, RSIS, RMDS ports 
simultaneously. If both functions are programmed at the same time on separate ports, the 
function of the lowest numbered RSIU, RSIS, RMDS port (TTY or modem) will be active.
lWhen uploading Program 76-1 with DKAdmin or DKBackup, the data will not change until 
the system power is cycled.
Program 76-2X-Z: Assigns each installed RSIU port to operate at a specified transmission rate. 
Where X identifies the RSIU port no. 1~4 (see Figure 7-23 for RSIU port number configuration) 
and Z identifies the RSIU, RSIS, RMDS port transmission rate in bits-per-second (bps).
Notes
lThe sum of the used RSIU, RSIS, RMDS ports transmission rates cannot exceed 9600 bps. 
Ports assigned as “non-function” (code 0) in Program 76-2X-Y will not be included in the 
transmission rate sum. The RMDS will only function at 1200 or 2400 bps.
lWhen uploading Program 76-2 with DKAdmin or DKBackup make sure that Program 76-2 
bps rate for the TTY/ modem port is set the same in: DKAdmin communications setup, 
DKAdmin customer database, and any DK424 RCTU. If the bps rate is not the same in all 
three areas, uploading will fail on Program 76
Program 77-1, LED 14: Enables the RMDS modem function. If the RMDS should function as a 
modem, turn ON LED 14. If the RMDS should function as a RS-232 port, turn OFF LED 14.
Program 77-1, LED 15: Sets the RMDS communications standard type to CCITT/V.22bis (2400 
bps) or Bell 212A (1200 bps). The standard set in this program must match the standard of the 
modem communicating with the DK424 RMDS.
If the RMDS modem standard should be CCITT/V.22bis, turn LED 15 ON. If the RMDS standard 
should be Bell 212A, turn LED 15 OFF. Most Hayes compatible modems will function with either 
standard. Check with the modem manufacturer’s documentation to verify which protocol should 
be used. When the system is initialized the Bell 212A standard is set (LED 15 OFF).
Program 77-4, LED 01/LED 02: Enables CLID, ANI, and/or DNIS information for ACD calls to 
be sent from the RSIU OA port.
ä
Turn LED 01 ON if the OA port should send CLID and/or ANI information for ACD calls.
ä
Turn LED 02 ON if the OA port should send DNIS information for ACD calls.
Program 77-4 allows LED 01 and LED 02 to be turned ON simultaneously, allowing CLID, ANI, 
and DNIS information to be sent from the OA port for ACD calls.
The system will initialize with LED 01 and 02 OFF–no CLID, ANI, or DNIS information will be 
sent from the OA port for ACD calls.

The RSSU contains one RS-232 serial port for connecting an SMDI, SMIS processor, DKAdmin/
DKBackup PC or external modem. 
One optional RSSU maintenance interface PCB can be used for connecting a maintenance PC or 
external modem (local or remote) to the DK40i.
A maximum of three RSSU cards can be supported per DK424.
The RSSU controls, indicators, and interface connectors are shown in Figure 7-25 and described in 
Table 7-17.
RSSU Installation
1.Insert the RSSU (component side facing right) into the last slot (“S16”) of the Base KSU/
cabinet if the system only has a Base KSU/cabinet and no Expansion KSUs/cabinets. If there 
are Expansion KSUs/cabinets, install the RSSU in the highest slot number in any KSU/
cabinet. Apply firm, even pressure to ensure proper mating of connectors.
NoteIn DK40i, RSSU can be installed in any available Expansion KSU.
2. After installing the RSSU, gently pull the PCB outward. If the connectors are properly mated, 
a slight resistance is felt.
RSSU Programming

Only one telephone (or device) can be connected to a RSTU2 port. If more than one telephone or 
device is connected to a port, ringing or message waiting may not function. RSTU2 only provides 
a 90-volt square wave message waiting generator to drive standard telephone 90V message 
waiting lamps.
Notes
lFor the system to recognize the DTMF tones generated by a standard telephone (or any other 
device connected to a standard telephone port), a DTMF Receiver Unit (RRCS-4, -8, or -12) 
must be installed on any DK424 RCTU or the DK40i K4RCU3.
lMost standard telephones and two-wire devices require the 190V P-P level; however, some 
devices may experience ring-trip with 190V P-P and should be set for 130V P-P.
See Figure 7-27 for an illustration of the PSTU1, PSTU2. Figure 7-28 shows the RSTU2. See 
Table 7-18, for details of the PSTU and RSTU2 controls and indicators.

RMCU/RCMS
E911 CAMA Trunk Direct Interface
System:DK424
Circuits per PCB:four circuits
Interfaces with:enhanced 911 locator services
Older Version(s): none
The E911 CAMA Trunk Direct Interface card (RMCU) enables cost-effective connection to the 
Enhanced 911 locator services without third-party equipment. Figure 7-31 shows the RMCU. The 
RMCU supports two subassemblies (RCMS) that provide a total of up to four ports as shown in 
Figure 73.
The RMCU has no CAMA circuits. It requires one RCMS subassembly to provide one or two 
CAMA trunks and two RCMS PCBs to provide up to four CAMA trunks.
When RMCU code 19 is entered for a slot in Program 03, that slot assumes the next four 
consecutive CO line numbers in the system. Only one RMCU PCB can be installed in a DK424 
system. If more than one slot is programmed with code 19 in Program 03, the lowest slot having 
code 19 will be the CAMA trunk active slot.
The controls, indicators, and connectors for the RCMS are listed in Table 90.
Location of the RCMS LEDs are shown in Figure 76.
Functions of the RCMS LEDs are given in Table 91.
A wiring diagram is shown in “RCMS Subassembly (stand-alone)” on Page 7-57.
RCMS Subassemblies Installation
1. Attach one or two subassemblies (RCMS) to the connectors on the RMCU as shown in Figure 
7-29. If only one RCMS is to be installed, install it in the bottom position.
2. Apply firm even pressure to ensure that the connectors are properly seated in the RMCU 
connector blocks. If they are seated properly, a light resistance is felt when you pull the units 
away from the RMCU.
