down block connection, then back out from there to the next WR-5 data input (J2 pin 2), out J2 pin 1 of that WR-5 back to yet another isolated punch down block connection, and so on, with the last WR-5 Data Output (J2 pin 1) wired back to the host unit’s Data In connection. In this type of cen- tralized wiring scheme, every WR-5 that returns its data signal back to the punch down block using J2 pin 1 must have its J6 jumper installed. Without the J6 jumper installed, the data input signal on J2 pin 2 is routed to J3 pin 2 for WR-5 series wiring as illustrated above. Maximum cable length for data integrity is 1,000 combined feet between any two active units.

When more than four WR-5s are being used, an external DC power supply is re-

quired. The power supply must provide at least 13VDC and no more than 35VDC. In addition, each WR-5 requires 30mA of current, (or 0.03 Amperes). To determine the minimum current rating of the power supply in mA, multiply 30 times the number of WR-5 remotes to be used (Note: 1000mA = 1A).

Ashly offers an Inline Power Booster called the RPS-18 that provides 24VDC and 625mA maximum current. It has common, euroblock-style terminals for easy insertion between the host data port and WR-5 Input jack. Alternatively, it can be inserted between the J3-LINK jack of any of the first four WR-5 remotes, and the J2-INPUT jack of the next WR-5 in the chain. This latter application can be useful to overcome voltage losses, caused by long cable runs to multiple remotes. In either application, do not connect the +18V pin from the host unit’s Data connector to the exter- nal supply +18V. It is possible to use the host unit’s +18V for the first four WR-5 remotes and then supplement any remaining WR-5 remotes with the inline power booster. Always connect the exter- nal power supply ground to the host unit’s Data connector ground.

Cable Length - Two things to consider when running cable to the WR-5 are data integrity

&power supply voltage. Active buffers (line drivers) in the WR-5 maintain data integrity, allowing up to 1,000ft (304m) of cable between devices. Thus, a maximum cable length up to 1,000ft may be used between the Remote Data Port and WR-5 remote, and another cable up to 1,000ft may be used from the WR-5 Link jack to an additional WR-5 remote, and so on. Hence each WR-5 functions as a data repeater.

However, long cable runs act as resistors, which reduce the DC power supply voltage delivered to the WR-5. Each WR-5 requires a minimum of 13VDC measured across J2-INPUT jack terminals 3 & 4. It is vital to keep track of the power supply voltage drop across each successive cable run to those pins. For example, typical CAT5 (24AWG) wire has a DC resistance of 0.026 ohms per foot.

Since there are two conductors, (V+ and GND), the resistance is doubled to 0.052 ohms per foot. Therefore, voltage drop across CAT5 wire can be computed as:

Voltage drop = current (in Amps) * 0.052 (ohms) * cable length in feet

Where current is computed at 30mA (0.03A) per WR-5. If the supply voltage at the WR-5 falls below 13VDC, the WR-5 will not power up. TIP: To minimize voltage loss over cable length, use multiple conductors for V+ and GND, (WR-5 terminals 3 & 4). For example, CAT5 wire has a total of eight 24AWG conductors. Use one pair for wiring up the two data terminals. Use three conduc- tors in parallel for V+, and use the three remaining conductors for GND. This effectively reduces the power supply voltage drop by a factor of three.
