3.0 SmaRT Handheld Remote to DIN-9H4R-2DI
The DIN-9H4R-2DI communications link to the system’s SmaRT remote is established at the
factory before the system ships. There may be times when it is necessary to establish, re-
establish, or break the link in the field. The process used to establish the link is called
“Association,”while the process used to break the link is called “Dissociation.”Appendix C of this
manual describes common Associate and Dissociate procedures for a variety of SmaRT remote
control units.
To Associate or Dissociate the DIN-9H4R-2DI to or from a standard SmaRT remote control unit,
see Appendix C.
✓ Note: Custom engineered systems may have a unique way of establishing the
communications link between the system remote control unit and the base unit. If you have a
customized system and need to Associate or Dissociate, refer to the custom Engineered
System Manual or Engineered Application Specific Supplement document provided with the
custom system when shipped.

Appendix A: Exposure to Radio Frequency Energy
When active, a SmaRT base unit sends out radio frequency (RF) signals through its external
antenna. Base units using an external antenna should be mounted to ensure the antenna is at
least 20 cm away from the human body. Only the external antenna recommended by Cervis, Inc.
is to be used (see Table 2).

Appendix C: Typical Handheld to Base Unit Communication
Handheld remote and base unit communications are established at Cervis, Inc. before shipping
when systems are ordered. However, it may be necessary to establish or re-establish
communication between a remote and a base unit at some point. The Associate procedure does
this.
A standard SmaRT system consists of one handheld remote and one base unit. Each base unit
can communicate with up to eight handheld remotes. Each handheld must first establish a
communications link with the base unit before the base unit will recognize the handheld unit.
This process is called “Association.”
In some cases, it may become necessary to break the communication link between the
handheld and the DIN-9H4R-2DI. This process is called “Dissociation.”
✓ Note: Be aware that when a handheld is dissociated from a base unit, all communication
links to that particular base unit are erased from the base unit memory! For instance, a
particular DIN-9H4R-2DI is associated to Handheld Remotes 1 through 5. Remote 2
dissociates—breaks the communication link—from the base unit. All five handheld remotes’
IDs delete from the base unit memory. The Associate procedure must be used by any
handheld that now needs to control that DIN-9H4R-2DI.
The following Associate and Dissociate procedures are general methods of associating or
dissociating Cervis, Inc. handheld remotes from the DIN-9H4R-2DI. Custom systems may have
different Associate methods unique to the custom system design; in which case, the
documentation included with that system must be referenced for the appropriate Associate
procedure.
C1: DIN-9H4R-2DI/PTO Remote Communication
To Associate
The base unit and handheld must be OFF before attempting to associate. Base unit and PTO 2-,
4-, and 6-button handheld association is established using the following steps:
1. Remove power from the base unit and turn off (PTO –time out) the handheld
device.
2. Stand near the base unit in unobstructed, clear line-of-sight with the handheld in
hand.
3. Simultaneously press and hold the Associate (B1) and Dissociate (B2) buttons.
The RX and ER LEDs light.
4. Continue to hold both buttons until TX and RX light steady.
5. When the TX and RX LEDs light, release B1 and B2. ER and BA light solid.
✓ Note: If the next button press is not immediately performed (approximately 2 seconds), all
LEDs flash, and the Associate procedure is aborted. Restart the process to establish the
communication link.
6. Immediately press and hold the Associate button (B1). All LEDs light.

7. TX begins to slowly blink. Continue to hold B1.
8. Apply power to the base unit.
The handheld and base unit begin to establish
a communication link while the Associate
button is held. Once the process is complete,
all LEDs light briefly and then go out.
9. Release the Associate button. The
SmaRT System is ready for use with
that particular handheld remote.
Figure 6. PTO Associate/Dissociate Buttons
To Dissociate
In some circumstances, it may become necessary to break the communication link—or
dissociate—a base unit and a PTO handheld remote.
Using the following steps will break all previously established handheld remote
links. It will be necessary to perform the Association Procedure (Appendix C1,
above) using each handheld to re-establish communication links with a base
unit.
1. Remove power from the base unit.
2. Stand near the base unit in line of sight with the handheld in your hand.
3. Press and hold both the Associate (Button 1) and Dissociate (Button 2; see
Figure 6). The RX and ER LEDs light.
4. Continue to hold both buttons until the TX and RX LEDs light steady.
5. When TX and RX light, release B1 and B2. ER and BA light solid.
✓ Note: If the next button press is not performed within the two-second interval, all LEDs flash,
and the Dissociate procedure is aborted. Restart the process to break the communication
link.
6. Press and hold the Dissociate button B2. (See Figure 6 above.) All LEDs light.
7. The TX LED begins to slowly blink. Continue to hold B2.
8. Apply power to the base unit while continuing to hold the Dissociate button.
The base unit begins to Dissociate communication links with all previously linked handhelds.
Once the process is complete, all LEDs light briefly and then go out.
9. Release the Dissociate button.
The SmaRT base unit will not communicate with any handheld remote units. A handheld remote
must use the Association Procedure (Appendix C.1, above) to re-establish a communication link
with the base unit.
