3.0 Functional Description
The WM-1000 is a state of the art spread spectrum unlicensed radio system that provides extended
coverage for mobile radio users. This portable radio system integrates with your exisng mobile radio to
give users handheld coverage when outside of their vehicle. With no license required, the WM-1000
oers ease of implementaon when compared to tradional SVR vehicular repeater systems.
The WM-1000 is used as mobile extender in cross-band operaon: the link is 915 MHz ISM Band
ulizing a tradional simplex mode of communicaons where the handheld WM-1000 unit can either
transmit or receive at any one me. The mobile radio that the WM-1000 is connected to can be Lo-band,
VHF, UHF, 700MHz or 800MHz trunking or convenonal. Proper care must be taken to prevent interfer-
ence between the mobile’s higher power transmier and the WB-1000 receiver. Proper antenna place-
ment is important even in this cross-band operaon.
Pyramid’s Smart Trunking II™ access gives portable radio users feedback of the handshake
status of their tethered mobile radio to system call status. This ensures that the portable user has com-
plete visibility of the trunking status to the main radio system. High speed data signalling between the
WM-1000 and the WB-1000 negoate the trunking access regardless of trunking format, EDAC’S™,
LTR™, P25™, Nexedge™, MOTOTRBO™ AND IDAS™. When channel access is granted the WM-1000 user
will hear a go ahead tone, acknowledging channel access.

The WM-1000 is congured to be uniquely paired to one or more WB-1000 base in the vehicle. The WM-
1000 has four channels. These channels can be selected using the mode knob on the WM-1000 handheld
and will select the RF channel and base paired to that channel. This provides private secure communicaons
to your vehicle mounted mobile radio.
In most cases, WB-1000 is powered from the DB-15 radio connecon and requires no external power supply.
There are provisions for external 12V DC on the rear of the WB-1000 for desktop charging/programming.
The WB-1000 is available in a “charge only” version (no RF), model number CH-1000.
The WM-1000 can be congured a couple of dierent ways, depending on the user requirements. First, if all
your WB-1000 base units are setup idencal, having the same RF Band (channel) and RF Address, the WB-
1000 units will operate in a mul-vehicle mode, where they will determine a priority vehicle and all handheld
from WM-1000 units will be passed through the WB-1000 that is priority. This allows handheld users to com-
municate with each other on a common channel (as in a simplex mode) and sll have communicaons with
their dispatch using the priority WB-1000. The WB-1000 base units ESP IITM structure works to establish one
priority vehicle on the scene to handle trac to and from the dispatch channel.
Second, you have the opon to program each of the WB-1000 base units with a RF Band and RF Address.
This will create a individual pairing from the WM-1000 to the selected WB-1000 and the handheld radios will
not hear each other on the 915 MHz link. They may sll be able to communicate with each other through
the mobile radio network, however, the communicaons between the WM-1000 and that WB-1000 is pri-
vate. There are four dierent RF Bands to choose from to reduce the chance of RF interference if operang
in this mode.

3.1 Cradle/Docking Staon Features
WB-1000 is a dedicated base and charger that interfaces seamlessly to most popular mobile radios.
When the WM-1000 transmits, the WB-1000 receives the transmission and in real me keys the Mobile
Radio retransming the conversaon back to the radio network (dispatch). When the mobile receives a
transmission, the WB-1000 base retransmits back to the WM-1000, extending the range of the wireless
microphone equal to your mobile two way radio.
Important: To congure (Pair) a WM-1000 to any WB-1000, insert the desired WM-1000 into the WB-
1000 and press the “PAIR” buon on the WB-1000 to program the WM-1000 for this Base unit.
3.2 Mul-Vehicle Operaon
When the WB-1000 is rst acvated, it listens on the channel for beacons from other WB-1000 units
that maybe be in the area. If no beacon is heard, it will assume the priority status and be ready to
repeat Base-to-portable (BTP) or Portable-to-Base (PTB) trac within 6 seconds. If there is another unit
already on scene, the arriving WB-1000 unit will go into a ‘standby monitor’ mode where it keeps track
in a table of all WB-1000 units on the scene.
Each WB-1000 sends a beacon at a 4 second interval. This beacon is used to communicate with the
other WB-1000 units and provide status update for which unit is in priority to non-prioirty units. This
method of determining the priority unit is referred to as ESP II tm.

ESP II tm also provides provisions in the event that there is handheld or base trac and the priority WB-
1000 is not available (disabled or le the scene) before a non-priority unit has assumed the priority
status. In the event that there is trac to repeat and no other unit is handling the call, a non-prioirty
WB-1000 unit will assume the priority status within the programmed “Priority Wait” me (default of
800mS) of acvity without reciprocal acvity on the opposing side of the call.
In other words, if a WB-1000 senses acvity from WM-1000 units, but no other WB-1000 has keyed
a mobile radio on the same channel within 800mS (determined by mobile COR), the non-priority unit
will revert to the priority state and begin handling the call. This same method is used if a call is re-
ceived from the tethered mobile radio and there is no WB-1000 trac on the 915MHz link, the non-
priority unit will assume a priority state within 800 mS.
3.3 Emergency
The WM-1000 has an emergency buon that can be acvated to send the WB-1000 and other us-
ers an emergency status. When the emergency buon is pressed, an audible alert is heard on the
originang unit. The originang unit can also be programmed to trigger a “Silent” emergency. Silent
Emergency simply creates a discrete emergency (no sounds) from the sending WM-1000 unit. When
other WM-1000 units receive the emergency from a WM-1000 user, the display on the receiving unit
will show the emergency status and ID of the sending radio as well as alarm the receiving user of the
emergency status audibly.
When the WB-1000 receives an emergency status from a WM-1000 user, it will assert the emergency
output line to the mobile radio, triggering the mobile radio (if congured) to enter an emergency
mode.

3.4 Trunking operaon (Smart Trunking II tm)
When the WB-1000 is connected to a trunking mobile, it should be programmed for trunking in the
CPS soware. The WM-1000 handheld operator will need to pair with the programmed WB-1000 at
least once to synchronize the programming from the WB-1000. Smart Trunking II
tm
creates a subset
of the mobile trunking system between the WB-1000 and the WM-1000 handheld user. Users will get
clear to talk tones on their WM-1000 handheld aer the WB-1000 negoates the handshake on the
mobile radio.
When the WM-1000 user keys their handheld radio, the WB-1000 will aempt to acquire a voice chan-
nel on the trunking system by keying the mobile for 200mS and monitoring the on-air detect line from
the mobile. If it does not see the radio transmit at all (system is busy), it will send a ‘low tone’ to the
hand held operator to alert them that the system is busy. If unsuccessful aer 30 seconds, the WB-
1000 will transmit low tone to alert the handheld operator that the call aempt failed.
In a successful call, the WB-1000 detects that the mobile is transming, it will connue to monitor the
on-air line unl the transmier remains keyed for at least 250mS to ensure that the radio isn’t merely
handshaking or retrying. Aer successful acquision of a voice channel on the trunking system, the
WM-1000 user will hear a ‘clear to talk’ beep from their handheld and know it is OK to begin talking.

Visit www.pyramidcomm.com
for up to date installation guides
on your specic mobile radio.
Before installing the WB-1000, ensure that the mobile radio is properly aligned per the manufacturer’s tuning
Instrucons. Addionally, ensure that the WB-1000 jumper switches are properly congured for use with the
parcular mobile radio that it will be connected to. Follow the applicaon note for your specic model of mobile
radio to complete the interface to the WB-1000. Applicaon notes can be found at www.pyramidcomm.com in the
support secon.
4.1 Switch Sengs
SW2 & SW3 - Serial Interface: If the WB-1000 is connected to a radio that supports an RS-232 connecon, such
as select Kenwood mobile radios, move SW3 to the RS-232 posion. If the WB-1000 is connected to a radio that
requires a RS-485 serial connecon, posion the switches in the RS-485 posion.
SW4 - Emergency Operaon: This jumper will congure the Emergency output of the WB-1000. SW4 determines if
the Emg output signal pulls to ground (NO, Normally Open) or breaks ground (NC, Normally Closed).
4.0 Installation

4.2 Radio Connecon
Make the connecons between the mobile radio and the WB-1000 cable as follows:
Pin 1: Ground. Connect to the radio’s chassis or ground plane.
Pin 2: Mobile transmit audio. Connect to the mobile transmit audio path or tone input. If connected to
the mobile mic input, ensure that the WB-1000 is programmed for at (common data). If connected
aer pre-emphasis, ensure that the WB-1000 transmit audio path is programmed for pre-emphasis.
The PTB audio adjustment in the CPS sets this output level to a range between 0-5VPP
Pin 3: Remote enable/disable. Connect to the radio’s auxiliary output or a separate switch to remotely
enable or disable the repeater. If this line goes high to acvate the repeater, ensure that CPS pro
gramming for Remote Enable Polarity is set to High. If this line is open collector from the mobile
radio, make sure to check the ‘pull up’ opon in the CPS for Remote Enable.
Pin 4: Mobile PTT output. Connect to mic PTT on the mobile radio, or a line that goes acve low to trans
mit. Pin 4 is an open drain output rated at 2.2A at 20VDC.
Pin 5: 12 VDC input. Connect to the radios 12V switched supply or a point capable of supplying at least
500mA of current.
Pin 6: Mobile receive audio. Connect this line to the mobile receive audio path before the volume control.
If pin 6 is connected to the mobile discrimminator, ensure that the WB-1000 receive path is
programmed for de-emphasis. If connected aer de-emphasis, program the receive
path for at. This input should be between 30mVPP and 5VPP. The BTP audio sengs in the CPS
sets the gain of the receive input amp.

Pin 7: Mobile COR detect. This line is used to indicate when the WB-1000 should repeat the transmission
to the WM-1000 handheld. Connect to a logic point in the radio that indicates proper tone and car
rier have been detected or the audio unmute line. If this line goes more posive during an unmute
condion, program the mobile COR line as acve high (in the CPS). If the line goes more negave
during an unmute condion, program the mobile COR line as acve low. If this line is open collec
tor from the mobile radio, make sure to check the ‘pull up’ opon in the CPS for COR.
Pin 8: Local mic audio. If programmed for local mic repeat, the WB-1000 will go into transmit mode and
repeat the audio from this line whenever the mobile radio is keyed by the local mic. Connect this
line to the mobile transmier audio path before liming or ltering. This input is AC coupled and
high impedance (>5.6Kohms). The input level at this pin should be 300mV to 5VPP. Use the Local
Mic Gain in the CPS to adjust the level of mic audio rebroadcasted out to the WM-1000 units.

Pin 9: On-Air detect.
Trunking: Connect to a point in the radio that indicates the mobile transmier is actually on the
air.
This is not the same as mic PTT. If pin 9 goes posive during transmit, program the on-air detect
line for acve high (common data). If pin 9 goes to ground during transmit, program the on air
detect line for acve low.
Convenonal: Used for local mic repeat indicaon from the mobile. Connect pin 9 to pin 4 of
the WB-1000 and program the on-air detect line for acve low.
Pin 10: Emergency Output. Connect to the Emergency input on the mobile radio. On Motorola radios,
the Emergency input opens from ground on acvaon and SW4 should be in the “NC” posion.
On all other radios, the Emergency input pulls to ground on acvaon and jumper SW4 should
be in the “NO” posion.
Install the WB-1000 in the vehicle using an AMPS mounng bracket hardware. Install the unit where
it will be easily visible by the driver and will not interfere with the drivers vision or constute a hazard during a
vehicle collision. The WB-1000 mounts in the bracket using the four 4-40 x 1/2” machine screws.
Do not use longer screws to mount the WB-1000 to the bracket or damage may result.
