Gasboy ME-800 SHM User Manual

INSTALLATION GUIDELINES - ME800 SHORT HAUL MODEM

The Series 1000 System can be wired for direct comm unication distances over 1500 feet using
ME800 asynchronous Short Haul Modems (SHM). One SHM is required for each end of the
communication line. Com munication can be through Port 1 (as shown) or Port 2 of the Series
1000 system.

It is recomm ended that a surge protection device (P/N C08159) be purchased for each SHM to
help protect it from transient voltages that can be induced into the communication lines. One
device is required for each SHM.

This mounting kit C05795, for the ME800 Short Haul Modem, provides a shelf and all the
necessary interconnect cables required for installation of the SHM into the Ser ies 1000 post. It
consists of the following:

C01168 Screw, 8-32 x 3/8
C02188 Bushing, Snap-in 5/8 ID
C35026 Bracket, SH Modem Mounting
C04660 Cable Assy., AC Power Receptacle
C04661 Cable Assy., RS-232 x 2' w/Spades
C34856 Instructions, Installation

NOTES:

1. The maximum distances specified by the manufacturer are listed below. These dis tances
are valid when using 22 or 24 AW G two twisted-pair unshielded cable. Shielded c able will
reduce distance to one-third of the table value. Please note that the pr oper wire, according
to National Electrical Code (NFPA 70), NFPA 30, and Automotive and Marine Service Station
Code (NFPA 30A) codes and regulations must be used when the m odem is installed over a
hazardous location.

300 baud - 10 miles 2400 baud - 5 miles

9600 baud - 2 miles

1200 baud - 10 miles 4800 baud - 4 miles

2. Field wiring must be made with point-to-point wire or cable. If telephone lines are used, they
must be point-to-point (not go through any type of switching equipment).

3. AC power for the SHM on the remote end should com e from the same dedic ated breaker
that supplies power for the data terminal (printer).

4. Set both SHMs for DCE (switch located inside SHM).

Installation requirements f or the SHMs are specified by the manufacturer. G ASBOY will not be
responsible for any problems encountered if these units do not perform properly.
