1.1.2 Features
· Low Power
+5V @ 20mA (Max) regulated power is supplied by the host/parent 3530-XXX via the
40-pin Expansion Interface Connector P1.
· ESD & Transient Susceptibility
The RS-232 I/O circuitry has been designed to meet the requirements of IEC 801-2 for ESD withstand capability up to 10KV and the requirements of ANSI/IEEE
C37.90.1-1989 (formerly IEE 472) for surge withstand capability.
· EMI Compatibility
EXPCOM232 Boards have been designed to coexist inside a shielded enclosure with the TeleFlow ä electronics. EMI radiation is insignificant and susceptibility is comparable or superior to associated electronics.
· Mounting
The EXPCOM232 Board measures 3.75” (9.525cm) in width x 4.0” (10.160cm) in height and mounts piggy-back on a TeleFlow or TeleRTU CPU Board.
· RS-232 Serial Port
EXPCOM232 Boards provide an additional RS-232 serial port that is programmable for rates up to 19.2Kbps. 3530-XXX units equipped with the EXPCOM232 Board can communicate with a local RS-232 device even though a radio or modem may be installed on the CPU Board’s network port.
1.2 COMPONENT IDENTIFICATION
EXPCOM232 Boards do not contain LEDs, switches or configuration jumpers. Two connectors are provided; 40-pin connector P1 mates with the host 3530-XX-X (connector J4 -
TeleFlow CPU or J18 - TeleRTU CPU) and accommodates the TTL interface between the two entities, while 7-pin connector TB1 mates with the RS-232 device that is being interfaced to the 3530-XXX. Additionally, the 3.5mm pitch plugable connector TB1 is removable from its mating EXPCOM232 Board socket.
1.3 INSTALLATION COMPATIBILITY
An EXPCOM232 Board can be installed into any of the following 3530-XXX models:
3530-10B - TeleFlow
3530-15B - TeleRTU
3530-35B - TeleRTU Module
3530-40B - TeleFlow ECR
3530-20B - TeleFlow Plus 3530-45B - TeleRecorder
3530-25B - TeleRTU Plus 3530-50B - TeleFlow Corrector
1.3.1 Restrictions
The 3530-XXX in question must be equipped with ACCOL application software. 3530-XXX units support installation of only one optional piggyback mounted Expansion Board (I/O,
Comm. or TIB).
