2.2DESCRIPTION

The Patton Model 1110ARC fiber optic rack card modem is the rack mountable counterpart to Patton’s Model 1110A self-powered, fiber optic modem. Communicating full or half duplex over dual optical fibers, the Model 1110ARC supports data rates to 19.2 Kbps and distances to 4 miles.

Like all fiber optic modems, the Model 1110ARC is inherently immune to RFI/EMI noise, ground loops and transient surges. The carrier may be switch selected as either “Continuously On” or “Controlled by RTS”. Four pairs of bi-level LED indicators monitor TD, RD, RTS and CD. A single LED monitors power.

The Model 1110ARC is designed to mount in Patton’s 2U high 19” rack chassis. This 16-card chassis has a switchable 120/240 volt power supply and mounts cards in a mid-plane architecture: The front “brains” half-card can be plugged into different rear “interface” cards. The Model 1110ARC is available with a choice of two interface cards: one with SMA connectors, and one with ST connectors. Both cards are equipped with an HD-26 female connector for the RS-232 interface.

3.0 CONFIGURATION

This setting describes the location and orientation of the Model 1110ARC’s configuration jumpers. There are two sets of jumpers to set: those on the front “brains” card and those on the rear “interface” card.

3.1 FRONT CARD SETTINGS

The jumpers on the Model 1110ARC “brains” card set RTS/CTS delay and carrier control. Figure 1 (below) shows their location on the PC board.

Figure 1. Model 1110ARC front card jumper locations

JP1 and JP2: RTS/CTS Delay

The combined settings for jumpers JP1 and JP2 determine the amount of delay between the time the Model 1110ARC “sees” RTS and

when it sends CTS.
JP1	JP2	Setting
Off	Off	No delay
On	Off	No delay
On	On	9.0 mS
Off	On	79.5 mS

JP3: Carrier Detect

The settings for jumper JP3 determines whether carrier detect is enabled or disabled. Carrier detect feature responds to RTS; if RTS is on, the Model 1110ARC will have a carrier.

JP3	Setting
On	Enabled
Off	Disabled
