1. PRODUCT OVERVIEW

The TASC Bi-directional Power Sensor 2 Series (BPS 2 Series) is a commercial grade device for monitoring forward and reflected power from a radio through a transmission line, to an antenna.

The BPS 2 Series is equipped with 2 female N-Type connectors, the Input (TX) connector should be connected to the BTS TX or TX/RX output at a point where the device has a good “view” of the antenna and the transmission line. The Output (ANT) connector should be connected to the transmission line attached to the antenna.

A 4 pin key lock connector provides the analog level out, power and ground which is wired to a TASC site monitoring device such as the siteCOMMANDER or siteRSM.

There is one connector per side (forward and reflected).

Figure 1 – Bi-directional Power Sensor 2 Series

1.1. AOUT

The AOUT output connects to one of the analog inputs of the TASC’s site monitoring devices (siteRSM or siteCOMMANDER). siteVIEW 2.0 and SCCU software provide the GUI used to monitor and set-up the alarm points for the forward and reflected power levels.

siteVIEW 2.0 provides a formula field to convert the analog level (VDC) into power (dBm or Watts).

The BPS 2 Series must be set for the 0-5VDC analog range to operate correctly. Please refer to the siteCOMMANDER (015-050-0002) or siteRSM User Manual (015-050-0052) for instructions.

Bi-directional Power Sensor 2 Series User Manual 050-015-0070R02

If a formula is required in the 40-2000Mhz range that is not in the appendix, please contact TASC Systems Inc for assistance.

1.2. GND

The GND pin should be connected to the system ground.

1.3. VDC

The VDC pin requires 6-26 VDC applied to its input.

1.4. DOUT

The DOUT pin provides an open-drain output that latches low when the TX or ANT input levels drop below a factory set threshold.

Voltages in excess of +26VDC will cause irreparable damage to the board. Please make sure that the 4pin press lock connector is properly seated before applying power.

2. INSTALLATION AND SETUP

These sections provide the necessary information to install the BPS 2 Series. The BPS 2 Series provides both forward and reflected power readings in the form of analog levels back to the TASC siteVIEW 2.0 software using the TASC siteRSM or siteCOMMANDER monitoring devices.

There are two ways to install the BPS 2 Series, one way is stand alone interfacing directly to a siteRSM or siteCOMMANDER, the second way is via the 19” rack configuration to a siteRSM 1RU or 2RU chassis via a D-Sub ribbon cable.

2.1. BPS 2 Series stand alone

The stand alone configuration connects the AOUT (RFL) and AOUT (FWD) directly to the TASC site monitoring products without the 19” rack.

In this configuration it is up to the user to extend the provided cable length to fit the application. Simply cut one end of the provided cable and strip the leads and screw them down to the analog input on the site monitoring device.

2.2. BPS 2 Series 19” Rack

The 19” rack mount configuration allows for easy installation of up to 4 BPS 2 Series units to one siteRSM 19” 1 or 2 RU rack. The rack mount configuration is equipped with a Female DB-15, 8 port interface board for easy integration.

The provided DB-15 ribbon cable interfaces the RF Power Monitor Output to the siteRSM 19” rack RF Power Monitor Input. See the image below.

Figure 2 – BPS Rack Configuration to siteRSM

Page 11

Bi-directional Power Sensor 2 Series User Manual 050-015-0070R02

When installing a new BPS to the 19” rack, the interface board consists of 4 RFL (Reflected) connectors on the top portion of the board and 4 FWD (Forward) connectors on the bottom as seen in the below image.

Figure 3 – RF Power Monitor Interface Board

Simply match the RFL cable on the BPS 2 Series to the RFL connector and the FWD cable on the BPS 2 Series to the FWD connector on the board. The image below shows how to interface one (1) BPS 2 Series to the interface board using the outside most connectors first, RFL 1 and FWD 1.

If only one Analog Input Expansion is installed, range 9 - 16 will be used to monitor BPS 2 Series input power. The channel allocation will be:

BPS1 BPS2 BPS3 BPS4 Analog Inputs 9 10 11 12 13 14 15 16 DB15 Interface FWD1 RFL1 FWD2 RFL2 FWD3 RFL3 FWD4 RFL4

If the manufacturer installed both Analog Input Expansion and BPS Input Expansion, range 17 – 24 will be used to monitor BPS Input Power:

BPS1 BPS2 BPS3 BPS4 Analog Inputs 17 18 19 20 21 22 23 24 DB15 Interface FWD1 RFL1 FWD2 RFL2 FWD3 RFL3 FWD4 RFL4

Figure 4 – Single BPS Connection

If using the 19” rack BPS with the siteCOMMANDER configuration, an interface cable will need to be created between the rack and the siteCOMMANDER analog inputs. Listed below is the pin out of the DB-15 RF Power Monitor Output connector.

Pin Description

1 RFL 4 2 GND 3 RFL 3 4 RFL 2 5 GND 6 RFL 1 7 VDC + (6-26VDC) 8 Not Used

9 FWD 4 10 FWD 3 11 GND 12 FWD 2 13 FWD 1 14 GND 15 GND

Please refer to the Related Documents section of this manual for information regarding physical configuration of the analog input jumpers of the siteCOMMANDER or siteRSM to accept a BPS 2 Series as well, please refer to the SCCU or siteVIEW 2.0 Software Manuals for information regarding software configuration of the analog inputs.
