Page 8: Introduction
CHAPTER 2: Introduction 2. Introduction 2.1 Description The Async/Sync Fiber Optic Modem is a miniature modem that combines the inviolability of fiber with the troubleshooting capabilities of V.52 and V.54 diagnostics. The modem operates in asynchronous or synchronous mode, supports data rates to 57.6 kbps, and plugs directly into a workstation’s RS-232 port. -
Page 9: Configuration Overview
The Async/Sync Fiber Optic Modem is fairly simple to install. The following instructions will help you set up and install the modem properly. If you have questions, call Black Box Technical Support at 724-746-5500. 3.1 Configuration Switches The Async/Sync Fiber Optic Modem uses a unique set of 16 external mini DIP switches that allow configuration to an extremely wide range of applications. - Page 10 CHAPTER 3: Configuration Overview 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 Figure 3-1.

Page 11: Configuration Switch Set S1
ASYNC/SYNC FIBER OPTIC MODEM The Async/Sync Fiber Optic Modem has two sets of eight switches, referred to as S1 and S2. As Figure 3-2 shows, the orientation of all DIP switches is the same with respect to “ON” and “OFF” positions. 1 2 3 4 5 6 7 8 Figure 3-2. -

Page 17: Installation
ASYNC/SYNC FIBER OPTIC MODEM 4. Installation The Async/Sync Fiber Optic Modem is easy to install. After configuring the DIP switches, simply connect the two fiber cables and then connect the RS-232 interface. Figure 4-1 shows the location of the fiber connections on the rear panel. Fiber Fiber Figure 4-1. -
Page 18: Operation
CHAPTER 5: Operation 5. Operation Once you have configured each Async/Sync Fiber Optic Modem and connected the fiber and RS-232 cables, you are ready to operate the units. This section describes the LED status monitors, the V.52 and V.54 diagnostics, and the power- on process. -
Page 19: Test Modes
ASYNC/SYNC FIBER OPTIC MODEM 5.1 Test Modes The Async/Sync Fiber Optic Modem offers two V.54 test modes to evaluate the condition of the modems and the communication link. These tests can be activated physically from the front panel or via the interface. NOTE V.54 test modes on the Async/Sync Fiber Optic Modem are available for point-to-point applications only. -

CHAPTER 5: Operation 5.1.2 R (RDL) EMOTE IGITAL OOPBACK The Remote Digital Loopback (RDL) test checks the performance of both the local and remote modems, and the communication link between them. Any characters sent to the remote modem in this test mode will be returned to the originating device. -
Page 21: Power-On
ASYNC/SYNC FIBER OPTIC MODEM 5.2 Power-On Once the Async/Sync Fiber Optic Modem is properly installed, it should operate transparently—as if it were a standard cable connection. Since operating power is derived from the RS-232 data and control signals, there is no On/Off switch. All data signals from the RS-232 interface are passed straight through. -
