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 SMR 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 trunking or conven onal. Proper care must be taken to prevent interference between the mobiles higher power transmi er and the repeater receiver. Proper antenna placement is impor-
tant even in this cross-band opera on. Pyramids patented 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. Sub audible signaling between the WM-
1000 and the WB-1000 nego ate the trunking access regardless of trunking format, EDACS, LTR, P25, Nexedge,, MOTOTRBO AND IDAS. When channel access is granted the WM-1000 user The WM-1000 System can be con gured to operate in one of two modes. First, the WM-1000 can be con gured to be uniquely paired to the WB-1000 base in the vehicle. This provides private secure communica ons to your vehicle mounted mobile radio. If you work together with other users on a regular basis, the WM-1000 can be con gured to work in group mode. This allows handheld users to communicate with each other on a common channel. The WB-1000 base units ESPIITM structure works to establish one priority vehicle on the scene to handle tra c to and from the dispatch channel. 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 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. WM-1000 User Functions WB-1000 Installation Before installing the WB-1000, ensure that the mobile radio is properly aligned per the manufacturers 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:

Pin 1:
Pin 2:
Pin 3:
Pin 4:
Pin 5:
Pin 6:
Ground. Connect to the radios chassis or ground plane. 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-1000transmit audio path is programmed for pre-emphasis. Pin 2 is AC coupled and has an output impedance of 600 or 2.2Kohms (determined by J2). RV3 sets the transmit audio output level and J1 sets the adjustment range between 0-5VPP (J1 open) or 0-
100mVPP (J1 shorted). Remote enable/disable. Connect to the radios 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 JP1 is set to the + posi on. If this line goes to ground, set JP1 to the - posi on. J8 has two posi ons to add a pull up (+) or pull down (-) resistor to this line if used with an open collector or dry contact output. 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 2A at 15VDC. 12 VDC input. Connect to the radios 12V switched supply or a point capable of supplying at least 2A of current. 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 SVR-P250 receive path is programmed for de-emphasis (common data). If connected a er de-emphasis, program the receive path for at. Pin 6 is AC coupled and high impedance (>15K ohm). RV5 sets the receive audio level sensi vity; this input should be between 30mVPP and 5VPP. J7 sets the gain of the receive input amp. If open, the input has a maximum gain of one; if installed, the input has a maximum gain of Pin 7:
Pin 8:
Mobile COR detect. This line is used to indicate when the SVR-P250 should repeat the transmission to the handheld. Connect to a logic point in the radio that indicates proper tone and carrier 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 (common data). If the line goes more nega ve during an unmute condi on, program the mobile COR line as ac ve low. The input from pin 7 is high impedance and does not have to go rail to rail. The SVR-P250 uses a voltage comparator as a COR threshold detector and is factory set at 1.6VDC. The COR input must go at least 0.5VDC on either side of this threshold. Local mic audio. If programmed for local mic repeat, the SVR-P250 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. RV2 sets the local mic sensi vity. If the mic high line has su cient drive for this input, install J4 and leave pin 8 unconnected. J6 sets the gain of the local mic input amp. If open, the maximum gain is one; if installed, the maximum gain is 10. 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 SVR-P250 and program the on-air detect line for ac ve low. Solder jumper J5 will connect pin 9 to pin 4 (PTT output) and can be used on conven onal systems only. 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 jumper J13 should be in the NC posi on. On all other radios, the Emergency input pulls to ground on ac va on and jumper J13 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 8-32 x machine screws. Do not use longer screws to mount the WB-1000 to the bracket or damage may result. 37 Shield, Irvine, CA 92618 714-901-5462 ww.pyramidcomm.com
